Links for March 6th through March 11th

March 12th, 2010

If you're new here, you may want to subscribe to my RSS feed or check out my popular posts in the sidebar. Thanks for visiting!

These are my links for March 6th through March 11th:

  • Resisting Dickensian Gloom | Planetizen – I often read stuff I don't agree with, just to keep myself in check. This article is pretty much the opposite of everything I believe. I don't even know where to start. Suffice to say, statistics can be manipulated to back up *any* theory. I'm still a big fan of cities though…
  • No more niches – we need sustainable innovation at scale (Jonathon Porritt) – "I spent a day last week at Ecobuild – ‘the biggest event in the world for sustainable design, construction and the built environment’. That absolutely wasn’t a claim that could have been made at the first Ecobuild, five years ago, which attracted no more than 1000 visitors. This year, there were more than 50,000 people there. Earls Court was flush with exhibitors, from some of the biggest companies in the UK to distinctly ‘alternative’ start-ups taking a massive gamble on enough people falling for their particular ‘breakthrough innovation’. There were countless meetings and debates going on the whole time, and the kind of buzz that one doesn’t always associate with events of this kind.<br />
    For the politicians who’d dropped in, and wandered around looking a bit bemused, it all said one thing: no more niches. This was about scale. New orders. Expanding markets. Innovation (in the construction industry!). And even, dare one say it, new jobs."
  • Making the connection with sustainable development – The Regeneration Blog – Spot on Jackie – read the whole thing: "We got onto discussing whether "sustainability is the new regeneration" in terms of being the new emerging exciting industry to be part of, for the Noughties and the Tens, in the same way as regeneration was the party-to-be-at for the Eighties and the Nineties. And our verdict was: well, yes!<br />
    The parallels are all there. Environmental jobs are created on the fringe and (at least in the general perception) are still not mainstream. Despite a pretty coherent case, environmentalists still seem to be outsiders, banging on the door of the establishment. Those who choose the environment industry tend to be as messianic and passionate, as pointy-headed, as we were when we "invented" urban regeneration, in London Docklands (among other places) all those years ago.<br />
    Environmental projects tend to need the same skills that we deploy in urban regeneration…"
  • Official figures show construction output falling again, but devils lurk in the detail | Brickonomics – More doom from Brian Green: "If you do a crude breakdown of the work sponsored by the public sector, doing your best to include PFI, and the work that is properly private sector, then you find that the public sector underpins close to half the work currently under construction. That compares with less than a third before the credit crunch (see graph 2).<br />
    For me that graph in one picture illustrates the increased level of risk in the construction market given the likely pattern of future public spending."
  • Fewer redundancy in construction, but the future remains bleak on jobs | Brickonomics – Well reasoned doom (as ever) from Brian Green: "underemployment is, to some extent, becoming the new unemployment.<br />
    Broadly, the proportional cost of overhead per person increases with the reduction in hours. This makes each person, theoretically, less productive financially from the employers’ perspective.<br />
    Firms may be prepared to carry this cost for a limited period, but if they see no sign of an upturn the likelihood is of a further wave of job cuts. With people working fewer hours and proportionately carrying larger overheads, this (proportionately) increases the numbers of jobs likely to go."
  • Feed-in tariff ‘killing off’ burgeoning UK small turbine industry | Environment | guardian.co.uk – Not that I'm necessarily standing up for wind, but the capital cost in this example is half that of the solar: "This will allow a 1.5KW turbine, producing an average of 800KWh a year in windy conditions – less than a fifth of the average UK household's electricity needs. By comparison, UK panel installer Solarcentury has estimated that the typical 18 metre square domestic solar panel installation would on average generate just over 2,000KWh – nearly half the average household's electricity consumption."
  • 2009: EPCs in numbers | National Energy Services – Data, data, data! At last some figures which might indicate how many Part L non-dom properties built per year.<br />
    ND EPC (non-dwellings) 111,312<br />
    The post focuses on domestic market, but this is the first time I've seen *any* data on numbers of non-dom EPC's.
  • The Archdruid Report: Energy Follows Its Bliss – Via Chris Tweed, a druid(?!?) explains exergy. Very long post – worth reading the whole thing: "In a very small way, as you sit there considering your cold coffee, you’re facing an energy crisis; the energy resources you have on hand (the remaining heat in the coffee) will not do the work you want them to do (warming your insides). Notice, though, that you’re not suffering from an energy shortage – there’s exactly the same amount of energy in the dining room as there was when the coffee was fresh from the coffeepot. No, what you have is a shortage of the difference between energy concentrations that will allow the energy to do useful work. (The technical term for this is exergy). How do you solve your energy crisis? One way or another, you have to increase the energy concentration in your energy source relative to the room temperature environment."
  • SuDoBE — Sustainable Design of the Built Environment – Good to see Chris blogging again: "In the context of heated buildings, the ability of a source of energy to “do work” can be interpreted as delivering warmth to occupants. But as the post on exergy suggests, the concentration of heat is important and concentrated sources of warmth indoors are only available from fossil fuels. The erroneous assumption often made about warmth is that it doesn’t matter how it is delivered as long as it is capable of creating a comfortable environment. However, we know thermal comfort depends on the recent experience. If I return home on a cold day, what I want is not a uniform level of heating, which is increasingly the norm in new, highly insulated dwellings with small heating systems, but a high temperature heat source that will help me recover from the outside conditions quickly. There is an aesthetic pleasure to this which should not be underestimated."
  • Creating excellent primary schools: A guide for clients | Publications | CABE – Helping primary school clients, working in either the local authority or the school itself, to make the most of new capital investment in their buildings.<br />
    There is a clear link between well-designed primary schools and pupil performance and behaviour. Successful school design is the result of hard work and collaboration between designers, contractors and visionary, committed clients.<br />
    Creating excellent primary schools takes readers step by step through the process, offering practical tools and a dozen inspiring case studies to show just what can be achieved.
  • Rethinking biomass boilers | News | Architects Journal – "The number of stories reaching the AJ about the shortcomings of biomass boilers is growing daily. Sources say a raft of schools are giving up on their maintenance-heavy wood-chip or pellet-fuelled boilers and are instead relying on back-up gas-fired boilers.<br />
    This does not seem to be deterring design teams working on the new wave of Building Schools for the Future schemes, 86 per cent of which are going down the biomass route. Garry Palmer, director of advanced design at AECOM, which has been carrying out detailed research into biomass boilers, understands why this is. ‘Biomass is almost certainly the cheapest in terms of capital cost, and is the easiest way to get the additional Department for Children, Schools and Families [DCSF] funding available for low-carbon schools.<br />
    ‘However, when you look at lifecycle costs, other routes are more cost-effective… but the DCSF carbon calculator does kind of push you down the biomass route,’ adds Palmer."
  • Making better use of Energy Performance Certificates and data: Consultation – Planning, building and the environment – Communities and Local Government – Hurrah – another consultation: "Energy Performance Certificates (EPC) and Display Energy Certificates (DEC) have an important role to play in supporting our carbon reduction aims by providing vital information about the energy efficiency of buildings in England and Wales and advice about measures to improve their energy performance. To enhance their contribution, we are consulting on a number of measures to help improve the effectiveness of EPCs and to make better use of energy performance data."
  • Frank Chimero has a blog. (How-To) – Good philosophy: "Why do we look for recipes? Because we’re risk averse. If we fail, it’s because someone else gave us the wrong recipe. We get to skip on the blame, but can claim the success.<br />
    But, there’s money in recipes. If there’s a recipe, that means there’s a secret. And you can sell a silver bullet. The thing is, most people that are giving you a recipe are pandering to your fear. “What if things go wrong?”"
  • Facing up the biomass emissions – BSEE – Building Services and Environmental Engineer – "…many biomass installations already use a cyclone or multi-cyclone to remove particles from flue gases. However, cyclones are totally dependent on the mass of the particles for removal, so while they will remove around 50% of the coarser particles they do not remove particles below PM10. This is why the new Directive and its emphasis on PM2.5 has such significance for biomass installations…<br />
    Until recently there has not been a financially viable alternative but Hoval has now optimised a ceramic filter for use in biomass installations – without making the overall cost of a biomass installation prohibitive.<br />
    Capable of removing up to 96% of PM2.5 and PM10 particles, ceramic filters can be used with any type of biomass boiler and can retrofitted to existing installations, so they have the potential to address many concerns (real of perceived) about particulate emissions from biomass."
  • Green Building Programs: The Fundamental Flaw! – Michael Anschel – Excellent point, well made (read the whole post): "If we are asking people to think about how everything is connected, how everything goes somewhere, how their actions impact other people, and about their relationship with nature, then why the hell are we telling them to check their brain at the door and pick up a code book? It is almost as moronic as suggesting the LEED AP test (an exercise in minutia), or the NAHB Certified Green Professional test (a joke) have the ability to turn someone into a green expert!<br />
    Green building requires you to think. In green building, there is no easy path or one-size-fits-all solution. The sooner everyone understands this, the sooner we can get back to the business of green building."
  • FT.com / UK / Economy & Trade – BAE chief throws spanner in gas fitters’ work – "Gas fitters, photocopier repairmen and other technicians should stop calling themselves engineers, according to the chairman of BAE Systems, the UK’s biggest manufacturing company.<br />
    “Britain suffers from a language problem in that the word ‘engineer’ is applied to a lot of different people who do a range of jobs,” Dick Olver told the Financial Times. “Professional engineers need to take ownership of the brand and keep it for themselves.”"
  • Environment Agency – Opportunity and environmental sensitivity mapping for hydropower in England and Wales – "The map is based on a report commissioned by the Environment Agency to assess hydropower potential of our rivers and the impact of developing them on the environment.<br />
    In total over 25,000 sites were identified. These sites represent existing structures within rivers such as weirs and lochs. As well as hydropower opportunities they are barriers to fish movement and migration.<br />
    If a hydropower scheme were built on every one of these barriers they could generate one per cent of the UK’s electricity needs. In reality, only some of these sites could be exploited due to environmental sensitivities, particularly the impact on migratory fish populations such as salmon and eels, as well as practical constraints such as access to the electricity network.<br />
    However, we identified around 4,000 sites where a sensitively designed scheme incorporating a fish-pass could actually improve the local environment as well as generate electricity."
  • Office for Renewable Energy Deployment (ORED) – Department of Energy and Climate Change – Note – they have three objectives – carbon reduction is only one: "Office for Renewable Energy Deployment (ORED)<br />
    ORED's mission is “To accelerate the deployment of renewable energy in order to reduce carbon emissions, increase energy security and create business opportunities in the UK”"
  • Tories set out plan for local design standards – Building Design – "A Conservative government would introduce a decentralised planning system where local authorities each draw up individual architectural and design standards, the party has confirmed.<br />
    Proposals to fast track schemes that do not attract objection from local people are also included in the party’s long-awaited planning green paper, Open Source, published on Monday.<br />
    “Legislation already requires councils to promote good design, yet many are struggling” Ruth Reed<br />
    The paper dismisses the current system as “almost wholly negative and adversarial” and instead envisages a broad brushstroke national framework of planning policy, combined with more distinctive regional policies.<br />
    But RIBA president Ruth Reed — who is supportive of the paper’s emphasis on design — said “struggling” councils must be given more resources if they are to draw up and maintain local architectural standards."
  • IES » » 111 ways to save energy – Interesting statistic: "Buildings in New York City account for nearly 80 PERCENT of its greenhouse gas emissions. More than buses, cars and taxis. And in a city with more than 10,000 cabs alone, the fact that buildings are the largest contributor of greenhouse gases is astounding."
  • Ian McEwan: Failure at Copenhagen climate talks prompted novel rewrite | Environment | guardian.co.uk – "He said was happy to class himself as "warmer" — a term increasingly used by climate sceptics to describe those who agree with the scientific consensus that human activity drives warming. "Though I am quite tempted sometimes to be a calamatist. There is something intellectually delicious about all that super-pessimism."<br />
    McEwan added that his research on climate had forced him to reconsider opposition to nuclear power. "We just don't have anything else that can run our cities on a windless night in February." Better nuclear energy than coal, he said. "It is rare that virtue and necessity collide. Sooner or later we're going to have to find a new energy source for mankind.""
  • News – dcarbon8 carbon & sustainability consultancy – Well done, and good luck to Guy: "Deloitte, the business advisory firm, has acquired dcarbon8, a leading carbon and sustainability consultancy, as it expands and evolves its environmental and sustainability consulting practice.<br />
    The deal sees Guy Battle, a founder of dcarbon8, become a Deloitte partner and its employees join Deloitte."
  • Real Life LEED: FREE Unlocked LEED 2009 Checklists That Don’t Suck! – Does Real Life LEED have a day job as well (I assume so). In awe of how helpful this website is – wish I had time to do similar stuff for BREEAM): "Below you'll find links to Excel checklists for each of the five v2009 (aka v3) rating systems (…if you think I'm going to try to revamp the LEED-Homes checklist you're insane). Each prints to a single page, has an area for notes, and is COMPLETELY UNLOCKED, so if you don't like something you can edit it on your own."
  • My biggest mistakes « Scott Berkun – Great advice from Scott – especially if you're in a large multi-dis consultancy: "Not staying with the same boss/group. When I was there (‘94 to ‘03), after a long stint on the IE team, I jumped around Microsoft every couple of years, putting my curiosity and passions ahead of climbing ladders. I wanted a diversity of experiences – I had four different job titles in nine years at Microsoft – but this made it harder to get promoted and, in some cases, to earn respect in the MSFT culture. The advice I give people all the time is pick your manager first. A great manager will negate most other work problems, whereas an awful manager will negate most other work pleasures. Good managers get promoted and often their best people rise with them."
  • Why scientists must be the new climate sceptics – opinion – 04 March 2010 – New Scientist – At the risk of opening up a massive can of worms again, NS points out why bloggers and tweeters shouldn't have risen to Amanda's bait (key phrase being unnecessary and ultimately harmful). Good article worth registering onto the site to read: "Last November, architecture journalist Amanda Baillieu wrote a column in Building Design that questioned whether the building industry should support cuts in carbon dioxide emissions. It was tame stuff, yet it prompted a torrent of criticism, some of it offensive. That was unnecessary, and ultimately harmful to the cause Baillieu's critics were fighting for. Now Baillieu is presenting herself as a brave soul, fearlessly standing up to climate science orthodoxy – despite having presented no evidence to challenge global warming."

Links for December 8th through December 10th

December 11th, 2009

These are my links for December 8th through December 10th:

  • ASHRAE’s Building Energy Quotient building labeling program – ASHRAE's BEQ (roughly equivalent to DEC) continues to be developed.
  • The Language of Sustainability: Why Words Matter | GreenBiz.com – Communicating sustainability: "Provide context for "sustainability," in that it means the ability to continue into the indefinite future by respecting the Earth's ecosystems, its limits, and providing space for the other beings on the planet to exist. Otherwise, we create perverse concepts like sustainable growth, as if we can continue unlimited growth in the face of limits."
  • The Greenest Brick is the One That’s Already in the Wall : TreeHugger – Great point: "He understands also that while a sustainable building must be durable, flexible and frugal, it must first be lovable,
    "because it does not matter how efficiently the building performs if it is demolished and carted off to the landfill in a generation or two because it cannot be loved."
  • Climate Change | Housing | Quarter-Acre Block – "But relatively high densities have little to do with the use of sustainable transport. The best performer is the Canadian capital, Ottawa, which is much less dense than Los Angeles and about the same as Melbourne. Brisbane has barely half Melbourne's density and a third that of Los Angeles, but use of sustainable transport is similar to Melbourne and more than twice the level in LA.
    Sustainable transport use has more to do with transport policy than density, which is excellent news for anyone concerned about the environment. It would take many decades and vast expense to substantially change the density of a city of 4 million people, and we don't have that much time. Climate change and insecure oil supplies are urgent problems, and we need solutions now. Fortunately, transport policies can be changed more quickly and with less disruption than urban form, so we might be able to keep our leafy suburbs and still save the planet."
  • Homophily « twopointouch – Something often on my mind. Tricky: "Often, when I read blogs and tweets, I know that the person writing is doing so because it in some way amplifies or enhances their professional career. A lot of people I connect with are consultants of some description in their jobs. Their job is to be wise and right. That makes them lovely people, by and large, but there are arguably downsides. It can very often have the side-effect of meaning that they are never going to go out on a limb or wish to seem controversial. It’s also a job where you need people to want to work with you, so you won’t go around telling potential clients or collaborators that they’re wrong."
  • House 2.0: The Copenhagen Blues – Great article from Mark Brinkley: ”Milliband minor answered thus: “By 2050, our economies will be six or seven times larger than they are now, and so we must ensure that all that growth is low or zero carbon growth.”
    I took a proverbial double take. Six or seven times bigger than 2010? That assumes something like a 10% annual growth rate every year for 40 years. And yet carbon emissions are due to fall by 80% by that time. Just how is that going to work?
    Historically, economic growth has been fuelled by carbon – almost every innovation we come up with involves substituting machines for human labour, which involves burning carbon somewhere along the line. Now we may be able to make machines which are less carbon intensive, but do you really think we will be able to get to zero carbon by 2050 whilst at the same time expanding the world economy by six or seven times?"

Links for November 27th through December 2nd

December 4th, 2009

These are my links for November 27th through December 2nd:

  • Smart Vendors: Biomass Supply Chain (UK) – Innovation & Cleantech – Possibly interesting (but very expensive – £150!) report on biomass (not sure how independent the authors are?): "The future evolution of the UK biomass supply chain will be significantly impacted by the opening of proposed major biomass power generation plants by firms like Drax Power and Prenergy in the next 3 years."
  • Debt storm threatens Dubai’s ambitions | Last Word | MEED – The most understandable commentary on Dubai which I have come across this week: "Dubai World has gone into a form of protective bankruptcy, similar to the US’ chapter 11 arrangements. It is a situation fraught with difficulties that could damage Dubai and the UAE. And the true scale of what Dubai owes is still unknown.
    But it is Dubai World’s creditors that face the biggest immediate problem. None can expect to receive any money until Dubai World’s assets and liabilities have been fully assessed, a judgement made about how big the gap between the two is and a schedule defined for when creditors will be paid, and how much. It is tough, particularly for those who are owed money today. But it is fair."
  • Regulation shapes revolution in Gulf sustainable buildings | Last Word | MEED – Interesting summary of green building accreditation throughout the Middle East. Will the Dubai ripples have an impact?:
    "Abu Dhabi’s new building code, regulations that make sustainability compulsory in all buildings and major retro-fits throughout the emirate, come into force on 1 January 2010."
  • First Net-Zero Neighborhood in the US Being Built in Boulder | Inhabitat – At last, some aesthetically pleasing (to my eye at least) net zero homes in my favourite US city, Boulder. Still enormous compared to the UK – 280m² for a townhouse is 3.5 times larger than the average new build UK home (76m² according to swing a cat):
    "Located on Broadway and Poplar Ave in Northern Boulder, the 1.5 acre neighborhood is conveniently located across from a market, shops and restaurants and with easy access via bus to the rest of the city. Six townhomes border Broadway, while six single-family homes sit back behind around a communal park. All the homes will be orientated to the south and photovoltaic systems can installed on the roof, which will completely provide the homes with all the energy they need."
  • Rebooting Britain: transform cities into lush jungles – Another article from Wired. This time, I have to disagree slightly – IMO London is currently the *only* UK city suitable for walking and public transport?: "Cities are at present vulnerable to the smallest interruptions in oil and gas supply. The first step in cutting this dependency should be a ban on private car ownership in metropolitan areas. Even a sprawling city like London can be comfortably navigated by walking, cycling, and use of public transport – powered, like delivery vehicles servicing businesses and homes, by batteries, biofuels, or hydrogen fuel cells. The great tidal flows of commuters could be reduced by rezoning commercial areas for residential use and introducing workshops and offices into residential areas, as in the human-scale, mixed-use street plans of medieval cities."
  • Rebooting Britain: tax people back into the cities – Really looking forward to PD Smith's new book. Here a flavour from Wired UK: "To create a low-carbon economy we need to become a nation of city dwellers. We tax cigarettes to reflect the harm they do to our health: we need to tax lifestyles that are damaging the health of the planet – and that means targeting people who choose to live in the countryside. We need a Rural Living Tax. Agricultural workers and others whose jobs require them to live outside cities would be exempt. The revenue raised could be used to build new, well-planned cities and to radically upgrade the infrastructure of existing cities."
  • When provided a choice, do people choose? – The Social Enterprise – Suw is spot on about adoptation of social media within companies (my experience on Yammer and Skype backs this up): "The successful implementation of social software doesn't stop with a technically successful roll-out. In fact, that's when the process begins because that's when your adoption strategy should kick in.
    Adoption is ultimately about behaviour change: persuading people that, for example,
    instead of sending an email to everyone with a new version of a document they are working on, they should put it on a wiki where it's easier to collaborate. This might seem like a small step – and for a few people it is – but for the majority that's a fundamental change to the way that they have learnt to work on documents."
  • Gordon Brown’s ‘eco town’ vision quietly shelved – Times Online – "Gordon Brown’s vision of establishing distinct “eco towns” across the country has been quietly shelved, it emerged today.
    The Government tried to keep up the project’s momentum by announcing a further 14 locations where “green developments” have local council backing.
    But it became clear the new sites will not be for the self standing towns of up to 15,000 homes originally envisaged by the Prime Minister.
    Most will be developments of no more than 5,000 homes on the edge of urban areas, which will be cheaper, easier to plan and attract much less local opposition than those first proposed by the Government."
  • Futerra Sustainability Communications – Conspiracies, Climate and Communication – More climategate fallout – Solitaire from Futerra defends her position (well said): "So in my own voice I want to get one thing straight; I hate climate change. I really really hate it and wish it wasn’t happening. Some of the climategate posts seem to imply we’re part of a ‘pro’ climate conspiracy. Considering how deeply and passionately I wish the darn thing wasn’t happening that accusation left me fish-mouthing in surprise. I don’t want climate change, I don’t like climate change, and I’m bloody annoyed that my best years will be spent trying to combat the darn thing.
    The horrible irony is how much I want the deniers to be right. If I had one wish it would be for climate change to be untrue, a blip, misread data, to slope off in embarrassment. If only."
    Now, can we stop being distracted by the semantics and arguments and get on with some design? Thank you.
  • CRED Guide | The Psychology of Climate Change Communication – Via Joanna Yarrow, a fascinating document on communicating climate change. Niggets include: "balance information that triggers an emotional response with more analytic information to leave a mark in more than one place in the brain."
  • A Climate Scientist Who Engages Skeptics – Dot Earth Blog – NYTimes.com – Read the whole article: "In grappling with this issue, I would argue that there are three strategies for dealing with skeptics…
    Most scientists retreat into the ivory tower. The CRU emails reflect elements of the circling of wagons strategy. For the past 3 years, I have been trying to figure out how to engage skeptics effectively in the context of #3, … Some of the things that I’ve tried in my quest to understand skeptics and more effectively counter misinformation include posting at skeptical blogs, such as climateaudit, and inviting prominent skeptics to give seminars at Georgia Tech. I have received significant heat from some colleagues for doing this (I’ve been told that I am legitimizing the skeptics and misleading my students), but I think we need to try things like this if we are to develop effective strategies for dealing with skeptics and if we are to teach students to think critically."
  • The Guardian – Poignant and depressing: "But I find I can't say this stuff anymore; not because I have stopped believing in climate change, but because I have stopped believing we can prevent it.
    Which is not to say that the End Times are here. One of the other problems with the climate change narrative is that it offers only two futures: Saving the World, or Apocalypse Now. We will probably get neither. More realistic is that we will experience what most previous human societies experienced – a painful decline after a period of over-expansion. We hear a lot about the year 2050: it is a handy date on which to hang our hopes of a "sustainable society", which has come to mean business as usual but without the carbon. It seems much more likely that by 2050 we will be mining our landfill sites for valuable metals and struggling to keep the electricity on, while we dream of the coral reefs that once flowered in the emptying oceans."

Sing a Song of Sustainable Cities

November 4th, 2009

Last night I had the immense pleasure of catching Jaime Lerner at the RIBA Jarvis Hall in Portland Place, London. I had originally come across Lerner on TED, Chris Anderson*’s brainchild. If you aren’t already aware of TED, go check out the many and varied lectures and performances.

Lerner is an architect and urban planner by trade and was also the mayor of Curitiba, in Brazil. Curitiba is the capital of Paraná. Lerner was mayor three times (1971–75, 1979–84 and 1989–92). In 1994, Lerner was elected governor of Paraná, and was reelected in 1998 until 2002.

Watch the video below, from TED which gives a very potted version (16 minutes) of what we were treated to last night. Lerner also talked at University of Westminster on Monday and will again tonight at BFI.

Jaime Lerner: Sing a song of sustainable cities

Some background (from Wikipedia) which was not given last night. Sunand Prasad and Nicky Gavron seemed to expect everyone in the audience to know exactly who Lerner was, but a lot of this I wasn’t aware of:

As Mayor, Lerner employed unorthodox solutions to Curitiba’s geographic challenges. Like many cities, Curitiba is bordered by floodplain. While wealthier cities in the United States such as New Orleans and Sacramento, have chosen to build expensive, and expensive-to-maintain levee systems to build on floodplain. In contrast, Curitiba purchased the floodplain and made parks. The city now ranks among the world leaders in per-capita park area. Curitiba had the problem of its status as a third-world city, unable to afford the tractors and petroleum to mow these parks. The innovative response was “municipal sheep” who keep the parks’ vegetation under control and whose wool funds children’s programs.

When Lerner became mayor, Curitiba had some barrios impossible to service by municipal waste removal. The “streets” were too narrow. Rather than abandon these people, or raze these slums, Lerner began a program that traded bags of groceries and transit passes for bags of trash. The slums got much cleaner…

Perhaps the crown jewel of Curitiba’s achievements is its Bus Rapid Transit system (called “Speedybus”). Originally, the city was given Federal money to build a subway (Curitiba is not a small town), but Lerner discovered that “heavy rail” like a subway costs ten times the amount for “light rail” (trolleys), which, in turn, costs ten times a bus system, even with dedicated bus ways. The “light rail” savings usually touted to sway municipal decision makers occur because even trolleys can have relatively fewer drivers than a 40 – 60 passenger bus. Lerner got Volvo to make 270 Swedish people accordion buses (300 Brazilians, says Lerner), so that the problem of a lower passenger number to driver ratio was no longer an issue. The City built attractive transit stops with the look and feel of train stations — and all the handicapped access equipment – inducing private firms to purchase and operate the buses. A hierarchy of buses of six sizes feed one other. The city controls the routes and fares, while the private companies hire drivers and maintain equipment.

Natural land-use patterns within the city of Curitiba support public transit systems. Buildings along the dedicated bus ways are up to six stories tall, gradually giving way, within a few blocks, to single story homes. This mix of densities ensures sufficient user population within walking distance of bus stops.

Lerner has a very broad, dare I say, holistic view of sustainable cities. Green buildings, recycling and transport are all individually important, but on their own, are not enough. That said, his talk focused very much on the transit system and also on the way he has since applied the principles to other cities. The fascinating thing about the transit sytem in Curitiba is that it isn’t subsidised at all – it pays for itself.

I found this quote via Green500 originally although the link seems broken now. The 75% of CO2 emissions was a number quoted by Lerner last night too:

Cities are an important battleground in the fight against the impacts of climate change. Worldwide they cover less than 1% of the Earth’s surface, but account for some 75% of CO2 emissions. London alone emits up to 44 million tonnes of CO2 a year.

One of the most striking points for me was the fact that he had the agency, as mayor, to introduce the changes he made, which must be a unique position of an architect/urban planner. He couldn’t wear both hats at the same time, but the experience in both fields rubbed off on each other.

A quote, which I think he uses in the TED video above,  is that to be creative, cut one zero from the budget. To be sustainable, cut two. With a vision or proposed solution, it is possible to create sustainable cities without necessarily spending a fortune.

Lerner has an infectious optimism when it comes to the future of cities. As a lover of cities myself, I was won over by his enthusiasm. The city is a much more effective scale for sustainability than individual buildings. As he said:

Cities are not the problem. Cities are the solution.

*It was only when I looked it up on Wikipedia I realised there were 2 Chris Anderson’s – I had assumed Wired/Long Tail Chris and TED Chris were the same person – they’re not! Ooops!

Links for August 21st through August 25th

August 28th, 2009

These are my links for August 21st through August 25th:

  • Welcome to Green Building Index – via IES: "GBI is developed by Pertubuhan Akitek Malaysia (PAM) and the Association of Consulting Engineers Malaysia (ACEM). It is a profession driven initiative to lead the Malaysian property industry towards becoming more environment-friendly. From its inception GBI has received the full support of Malaysia’s building and property players. It is intended to promote sustainability in the built environment and raise awareness among Developers, Architects, Engineers, Planners, Designers, Contractors and the Public about environmental issues. The rating system will provide opportunity for developers to design and construct green, sustainable buildings that can provide energy savings, water savings, a healthier indoor environment, better connectivity to public transport and the adoption of recycling and greenery for their projects…Malaysia’s Green Building Index or GBI will be the only rating tool for the tropical zones other than Singapore Government’s GREENMARK."
  • BREEAM points for energy efficiency – 11/06/2008 – Contract Journal – This is an oldie but worth stating:
    "If people are a few points short, it could encourage them to step back and think innovatively about the project."
    Um, sorry, nope. At least I hope not. Embedding sustainability into a design, this is not.
    The point of innovation credits was to reward forward thinking which BREEAM has not yet covered, not a chance to tag on stuff at the end when you realise you're not going to get enough points.
  • UK Government CO2e Targets & Seeing Through the Eco-hype – "Key to acquiring the in-depth knowledge that will be needed to prosper in the world of low carbon building will be an understanding the political drivers for policy. Policy that experience has shown us is almost always re-active. Therefore, by gaining an understanding of the political pressures exerted by the challenges of climate change it should be possible to see where policy might be going next and how to address the necessary measures. This will give businesses a significant commercial advantage over competitors who will inevitably be playing catch up."
  • Putting Urban Planning In the Hands of the People | GOOD – “Many planning meetings are boring, contentious, and fail to stir people’s creative energy,” says Rojas. Even though planners consistently work closely with groups of constituents, they’re stuck with the kinds of tools they like to use: maps, words and pictures. Well, not everyone can understand a complex map. Other people are uncomfortable writing. And even the physical tools—Post-It notes, simple blocks, whiteboards—that planners use during charrettes do nothing to get the imagination pumping.
    “My process gives the public the power to create,” says Rojas. ”Giving people small interesting objects sparks their interest. Creating a 3-dimensional world with 3-dimensional forms breaks down the planning process into simple terms and helps participants translate conceptual planning ideas into physical forms.” Additionally, Rojas gives power to groups that might be disenfranchised by the typical neighborhood council meeting.
  • Leeds on frontline of local climate response | Sustainable Cities – ‘At the moment in all major cities outside London our fate is not in our own hands, we don’t have the financial wherewithal to do what the Victorians did. What I would very much like is the same sort of autonomy that London has with its mayor. If the city region had a mayor with the same powers, that would be a considerable leap forward because it would give you much more of a focus and much more chance to raise money. Please devolve power to us – trust us – is the message.’
    So what would he do with that power? One simple idea would be to introduce a London-style Oyster card for buses, trains and taxis in the city region. ‘The buses would then move much quicker and they’d be more attractive because at every stop at the moment they’re fiddling with change. It’s no surprise that London has a far better public transport system than Leeds. If we had something that was half as good it would be an improvement on what we’ve got now.’
  • Business case made for sustainable design | Sustainable Cities – "‘Our tenants are asking for things like more daylight, lower running costs and quantifiable carbon emissions and they are starting to embed sustainability in to their design and delivery process. The landlord tenant relationship is critical In order to achieve a high level of sustainability within a project. For the tenant space to be able to be sustainable, they need the base building to work with them. Everyone is noticing that landlords and tenants are starting to talk to each other more about delivering sustainable outcomes.’
    … In 2007 the company introduced a ‘green lease’ to provide a clear legal structure for increasing environmental accountability and to create a shared commitment to greater energy, water and waste efficiency. More than 360 green leases have now been signed in the UK for both offices and retail and another eight have followed in France. The success is due to the lease promoting collaboration and partnership and not being too prescriptive."

July 17th, 2009

These are my links for July 14th through July 16th:

  • Sustainable Homes – This could open the doors for more LA's to impose CSH (and BREEAM?) levels for planning conditions: "Chelmsford Borough Council requires that Code for Sustainable Homes Level 3 is achieved as a planning condition for new buildings. The developer appealed against this condition but following consideration by the Planning Inspectorate the condition was held as "reasonable and necessary"."
  • House 2.0: On triple glazing – Mark Brinkley warming to the idea of Passivhaus: "comfort underlies the PassivHaus take on triple glazing. I have been a voice arguing that triple glazing is “overkill” in the UK climate and that the energy used in making these units would probably never be repaid by the energy saved over their lifetime. However, the main reason for using triple glazing is not to save energy but to provide more comfort, as the internal temperatures remain more even.
    Feist produced a table showing what the temperature differences were close to different forms of glazing when the internal temperature is designed to maintain at around 21°C and the external temperature drops to —5°C.
    • next to a single glazed window, the adjacent temperature is around 1°C
    • next to a double glazed window (2000 vintage), the adjacent temperature is around 11°C
    • next to a triple glazed window, with a centre pane U value of just 0.65, the temperature is 18°C."
  • Portland Architecture: A man struggling: Guy Battle comes to Portland – Guy stands up for engineers: "Do engineers deserve more credit?
    Yes, I think so. Engineering is the hidden hand. They have an enormous amount to contribute to architecture, but too often their contribution is gently put to one side. I think it’s something that should be celebrated. You look at someone like Peter Rice or Neil Thomas, Chris Wise, Guy Nordenson, and a host of other fantastic engineers, and they don’t really get the recognition they deserve."
  • Ashden Awards (Jonathon Porritt) – Kirklees (again): "Kirklees Metropolitan Borough Council – one of the unsung heroes of local government who have been doing their "sustainability bit" for the last 20 years. But their current home insulation initiative has really made people sit up and listen as it has succeeded in achieving real scale – where so many of the current measures are just picking around at the edges. Here’s what the Award citation said:
    "In 2007, Kirklees Council committed £10 million to providing free loft and cavity-wall insulation for every home in the borough where it can be used. The scheme targets one council ward at a time, using the local Councillor and local advertising, then individual home visits by assessors. By May 2009, 66,000 out of the 172,000 households in the borough had been assessed, 54,000 referred for surveys, 26,000 surveys had been completed, and 21,000 had insulation installed. This avoids an estimated 18,000 tonnes a year of CO2. 140 jobs have been created by the scheme.""
  • Cutting carbon with smart finance | Forum For The Future – Innovative financing examples: "For instance, Kirklees’ Re-Charge scheme loans householders money to install low-carbon technologies in their property, such as solar panels to heat water. It is successful because there are no interest charges and the money does not have to be repaid until the property is sold. The council only has to subsidise the interest on the loans and this costs around three times less per home than using a grant scheme."
  • FT.com / Weekend columnists / Tim Harford – Carbon footprinting: time to pick up the pace – The ever lucid Tim Harford:"The carbon-footprinting process often produces surprises. An environmentally conscious consumer in the crisps aisle of the supermarket will probably be thinking about packaging or “food miles”. The Carbon Trust reckons that about 1 per cent of the climate impact of a packet of crisps is from moving potatoes around. The largest single culprit is the production of the nitrogen fertiliser, and half of the climate impact in general takes place at the agricultural stage. The point is not that agriculture is always the problem, but that it is very hard for a well-meaning consumer to work out what the green purchasing decision actually is. For this reason, the Carbon Trust has a carbon labelling scheme. The trouble is that many consumers simply do not care enough to pay more or choose a less enjoyable product simply because of the low carbon label."
  • Ground Control | PD Smith | Kafka’s mouse – Minton's book duly added to my wishlist. Review: "Sections of our city centres are being sold off to private developers to create shopping monocultures such as Westfield London or "malls without walls" like Stratford City, which is being built for the 2012 Olympics and is one of the largest retail-led developments in Europe. It is, says Minton, "a private city within a city" and represents a return to the early 19th century when aristocrats owned great swathes of London, fortifying their estates of up-market housing with gates and private security forces.
    Now, “land and property which has been in public hands for 150 years or more is moving back into private hands”. Minton argues that today’s privatised city centres and gated communities are fostering "a new culture of authoritarianism and control"."
  • Market Research Strategies – Excellent article on generating leads in a down turn market. Primarily aimed at US architects, but easily relatable to UK and engineers/consultants.

Links for June 3rd through June 5th

June 9th, 2009

These are my links for June 3rd through June 5th:

  • ECUK – Sustainability – Engineers chartered with EC now explicitly expected to "Do more than just comply with legislation and codes": "ECUK’s Guidance on Sustainability clarifies the role of engineers in relation to sustainability and lists six principles to guide professional engineers in their work. It should be read alongside sustainability related information produced by Professional Engineering Institutions, such as codes, policy statements or guidance of a technical nature. "
  • Sustainable legislation: keep it simple – Building – Pooran Desai of BioRegional takes on CSH: "Up to Code Level 4, the outcomes from an environmental persepective are basically sound though the metrics can be made more straightforward, robust. However, Code 5 and 6 as they are currently written are of dubious environmental value. The industry now generally accepts that forcing ‘net zero carbon’ on-site electricity generation is not helpful. There are other problems. On higher density sites particularly where you can’t collect sufficient rainwater to flush toilets, it forces on-site grey water treatment, often energy and chemical intensive, when even the Centre for Alternative Technology states that conventional sewage treatment is more eco-friendly than on-site grey water recycling. The solutions needed to deliver Code 5 and 6 are not just expensive in capital terms, but may not be kept operational because of high maintenance costs. This means that many homes built to current Code Level 5 and 6 will be less eco-friendly than Code 4."
  • Genuine partnership remains the key to regeneration success – The Regeneration Blog – Excellent point, and not just for regeneration, but the entire construction industry: "I was at a conference the other day when a very clever person (oh, I wish, I wish, it had been me) said "less than three years ago we were confidently asserting that we had seen the end of boom-and-bust, now we are bust we are pinning our hopes back on the forthcoming boom. Well, you can't have it both ways"."
  • Lord Turner on failed markets, irrational markets and environmental policy – 21 May 2009 – "The CCC’s report concluded that the electricity sector would have to be radically decarbonised by the 2030s in order to meet the 80% 2050 target. This cleaner electricity could then be applied, across other sectors such as transport, to help reduce emissions. He said that the CCC had concluded that the volatile nature of the financial market, with its direct impact on carbon and fossil fuel prices meant that a wholly market-led approach to tackling climate change would simply not work. Stronger policy instruments, coupled with government intervention would be needed to deliver the radical changes required."
  • Living Building Challenge Version 1.3 — ILBI – A kind of supplement to LEED, via CRGBC: "The Living Building Challenge is a rigorous performance standard that defines the closest measure of true sustainability in the built environment, using a benchmark of what is currently possible and given the best knowledge available today. Version 1.3 is comprised of sixteen prerequisites within six performance areas, or Petals: Site, Energy, Materials, Water, Indoor Quality, and Beauty + Inspiration."
  • China’s Grand Plans for <br/>Eco-Cities Now Lie Abandoned by Christina Larson: Yale Environment 360 – Arup's mythical Dongtan – lessons learned (a must-read): "Dongtan and other highly touted eco-cities across China were meant to be models of sustainable design for the future. Instead they’ve become models of bold visions that mostly stayed on the drawing boards — or collapsed from shoddy implementation. More often than not, these vaunted eco-cities have been designed by big-name foreign architectural and engineering firms who plunged into the projects with little understanding of Chinese politics, culture, and economics — and with little feel for the needs of local residents whom the utopian communities were designed to serve."
  • NYCDOT – Street Design Manual – "The New York City Street Design Manual provides policies and design guidelines to city agencies, design professionals, private developers and community groups for the improvement of streets and sidewalks throughout the five boroughs. It is intended to serve as a comprehensive resource for promoting higher quality street designs and more efficient project implementation.
    The Manual builds on the experience of innovation in street design, materials and lighting that has developed around the world, emphasizing a balanced approach that gives equal weight to transportation, community and environmental goals. It is designed to be a flexible document that will change and grow, incorporating new treatments as appropriate after testing. The use and continued development of the Street Design Manual will assure that New York City remains a leading innovator in the public realm as it becomes a greater, greener city."
  • Eco-ventilation health scare prompts regulation change – Building – "The draft report by the BRE’s Dr Michael Swainson and seen by Building, found that filters were not being replaced when worn out, which could lead to a build-up of humidity, carbon dioxide and other pollutants, as well as driving up energy use. It also says this could increase the risk of cancer in the homes of smokers.
    Mechanical ventilation systems are required in energy-efficient airtight homes to make sure that fresh air can circulate and that pollutants and humidity are extracted from the house. However, like a hoover, if the filter is not replaced the system stops working.
    The systems are virtually unavoidable if a home is to meet level four of the Code for Sustainable Homes, which all new homes in the social sector must meet by 2010."

June 2nd, 2009

These are my links for May 26th through June 1st:

  • Concentration Solar Power Module Integrates Into Side And Roof Of Buildings – min-CSP – intriguing but no data in the article to back up the theory: "The system, of which the international patent has already been requested, consists of a stationary lens and a linear absorber plate that concentrates sunlight to generate energy. This concentration system reduces the space that until now was needed with traditional plates, which move around in search of sunlight"
  • UK Climate Impacts Programme – Socio-economic scenarios – Getting quite old now (Feb 2001) but sets forward 4 potential scenarios for socio-economic situations against which climate change will play out in the UK :
    1. National Enterprise
    2. Local Stewardship
    3. World Markets
    4. Global Sustainability
    At 140 pages, it's not a quick read, but useful resource.
  • A glimpse of the future as 56% of surveyors see workload fall (Brickonomics) – More sound commentary from Brian: "But for all the figures on workload, the two bits of data that will probably reflect most the long-term effects of the recession are those for employment and for profit margins. Both continue to look grim.
    It may sound like a management course cliché but one of the biggest weaknesses of the construction industry is one of its biggest strengths, its flexibility.
    And this weakness is exaggerated by the easy willingness of firms to work at below cost.
    My recollection of the 1990s recession was the less damage was done by falling workloads, which the industry's flexibility can absorb without huge stresses, than was done by winning work below true cost or at unsustainable thin margins."
  • Monbiot.com » How Much Should We Leave in the Ground? – I had wondered about this before – good to see George has done the math for me: "Even ignoring all unconventional sources and all other greenhouse gases and taking the most optimistic of the figures in the two Nature papers, we can afford to burn only 61% of known fossil fuel reserves between now and eternity." This would result in a 2ºC rise in temperature. Adaptation, here we come…
  • Monbiot.com » Crash Landing – Monbiot being unusually level headed: "we were told by both the airline companies and the Confederation of British Industry that business flights were necessary and non-negotiable: civilisation would collapse if executives weren’t able to fly whenever and wherever they wished. The government repeated this creed, insisting that the UK economy was dependent on the expansion of Heathrow. Now we learn that these are the first expenses to be cut when a contraction begins. Businesses are discovering that there are other means of engaging with people overseas, such as email, video-conferencing and an outlandish new device called the telephone."
  • ACE – If we can’t count the buildings, how can we plan cuts in emissions? – There's an elephant in the room, and his name is data: "There is no definitive data showing precisely what the carbon footprint of Europe's buildings is. So we can have no confidence we can identify precisely what percentage of the carbon dioxide emissions by end use comes from space heating as opposed to water heating, lights and appliances as opposed to cooking."
  • Why Has Globalization Led to Bigger Cities? – Economix Blog – NYTimes.com – Great article on cities with a slant on India: "The right response to the problems of megacities is not to get misty-eyed about village life, but rather to work to improve the quality of infrastructure in those growing urban areas."
  • FT.com | The Undercover Economist | Dear Economist: Can you help me to stop procrastinating? – How to cope with procrastination: "The behavioural economists Dan Ariely and Klaus Wertenbroch conducted an instructive study of procrastination with three groups of students at MIT. Each group had to complete three assignments over the course of the 12-week course. The first group had a separate deadline for each paper, after four, eight and 12 weeks. The second group had no intermediate deadlines: all three papers were due at the end of the course. Students in the third group were asked to impose their own deadlines.
    Students with well-spaced deadlines – those in the first group and a subset in the third who had spaced out their deadlines – tended to achieve the highest grades. Students who had assigned themselves no intermediate deadlines, or had been assigned none, fared poorly."
  • A new era for public health? « – "Yet one group of very important people now admit they too have neglected the issue. The latest edition of The Lancet – probably the world’s leading medical journal – says health professionals “have barely begun to engage with what should be the focal point for their research, preparedness planning and advocacy”. Now doctors see climate change as “the biggest global health threat of the 21st century”.
    The Lancet calls for a “new public health advocacy movement” to usher in an unprecedented era of co-operation between widely divergent spheres such as disease, food, water, sanitation, shelter, settlements, extreme events, population and movement.”"
  • Prince fails on sustainability – Building Design – A bit late getting to this one – Amanada takes on Charles: "This is where the speech unravelled for in making out “experimentation” to be a terrifying leap in the dark rather than something good based on hypotheses and a body of knowledge he came across as an intellectual Luddite, whose only solution is to retreat into a Hobbit-like world of organic earthy buildings and no cars."
  • Carbon-effective refurbishment – Modern Building Services – Ant Wilson calls for an integrated approach to refurbished buildings: "At the same time, the lower metre could be well insulated and fitted with photovoltaics (PVs) and internally lined with phase-change boards. Emerging concentrated photovoltaic energy generation (CPV has around 1000 times less embedded energy than conventional PVs, and its price is falling rapidly, which will improve the cost-effectiveness of building-integrated PV in coming years."

Links for April 7th through April 9th

April 14th, 2009

These are my links for April 7th through April 9th:

  • Insulation is king – part 2 – "When NOT to insulate
    Some properties, typically built before 1940, have no vertical damp proof course (VDPC) around the windows. They rely on the ventilation in the cavity to stop rainwater penetrating to the inside wall. In this case you will need to either insert a VDPC or not fill the cavity.
    In any house, cavity wall insulation will reduce ventilation, preventing natural moisture build-up from being removed. So if you have cavity wall insulation make sure you also have trickle vents or extract fans."
  • Interior Design Trends – Garden Landscaping Ideas – Beautiful Homes | Maryland – Northern Virginia – Washington, DC – Passivhaus – Always interesting to see reactions to Passivhaus (more desirable than LEED?):
    "The thought of a home so efficient that it doesnt need a HVAC system is quite intriguing, and for some, more desirable than a LEED cert. The PeakOiler's will love it. Of course, our HVAC contractor might not like the concept too much, but hey, there's still ductwork to run and an ERV to take care of. …
    Another one of my concerns is that the home is that the home I've seen are necessarily boxy and without much exterior detail. According to Katrin Klingenberg, an architect who built one of these in Champagne Urbana, IL, "The surface/volume ration has to be very good… you do not want to have a lot of nooks sticking out of your house… because you lose energy". This runs counter to our typical bungalow designs that are quite high on the nook and cranny ratio."
  • Forestry Commission – The Trees and Design Action Group – via Hatty at the AJ Footprint blog (an excellent blog, BTW), "No trees, no future" report from Forestry commission.
  • Sustainable Energy Without the Hot Air: the Freakonomics of conservation, climate and energy – Boing Boing – Great review from Cory of David McKay's Without Hot Air. I think I'm going to have to cave and buy on paper – I've not opened the electronic version I downloaded months ago and this review really makes me want to read it.
  • Reinventing America’s Cities – The Time Is Now – NYTimes.com – "With their crowded neighborhoods and web of public services, cities are not only invaluable cultural incubators; they are also vastly more efficient than suburbs. But for years they have been neglected, and in many cases forcibly harmed, by policies that favored sprawl over density and conformity over difference.
    Such policies have caused many of our urban centers to devolve into generic theme parks and others, like Detroit, to decay into ghost towns. They have also sparked the rise of ecologically unsustainable gated communities and reinforced economic disparities by building walls between racial, ethnic and class groups.
    Correcting this imbalance will require a radical adjustment in how we think of cities and government’s role in them. At times it will mean destruction rather than repair. And it demands listening to people who have spent the last decade imagining and in many cases planning for more sustainable, livable and socially just cities."

Links for March 31st through April 6th

April 7th, 2009

These are my links for March 31st through April 6th:

  • Sustainable Design: What Do Europeans Know That We Don’t Know (But Should)?- 3/1/2009 – Building Design & Construction – "The respective roles of regulation and market forces are quite different in Europe from what we expect in the U.S. and Canada. That's one of the fundamental current differences that are likely to converge over the next five years, as the U.S. and Canada face up to the carbon reduction challenge. Generally speaking, in Europe, and especially in the U.K., people expect their governments to regulate, so government incentives for energy-efficient buildings are less prevalent there than they are in the U.S., or even in Canada."
  • Top 10 Myths about Sustainability: Scientific American – Fantastic (long) article:
    Myth 1: Nobody knows what sustainability really means.
    Myth 2: Sustainability is all about the environment.
    Myth 3: “Sustainable” is a synonym for “green.”
    Myth 4: It’s all about recycling.
    Myth 5: Sustainability is too expensive.
    Myth 6: Sustainability means lowering our standard of living.
    Myth 7: Consumer choices and grassroots activism, not government intervention, offer the fastest, most efficient routes to sustainability.
    Myth 8: New technology is always the answer.
    Myth 9: Sustainability is ultimately a population problem.
    Myth 10: Once you understand the concept, living sustainably is a breeze to figure out.
  • Visualising sustainability « Computing for Sustainability – An incredible resource – 158 different visualisations of definitions of sustainability. I can't remember who send me this – thanks whoever it was.
  • ArchNewsNow – WORDS THAT BUILD: Re-invent Green Communication – Great article from a great series. Can easily substitute BREEAM for LEED and it will read the same: "Your goal is to filter the enormous written text of LEED and deliver the gist of relevant LEED issues into commonplace and yet engaging English. This isn’t as quixotic as it might initially sound. The advantage of LEED language over odious “GREENSPEAK’ or “ECOMARKETBABBLE” is that it traffics in concrete specifics within building systems. The downside of LEED language is that it borders on “official” bureaucrat-ese,” the palaver of numbed technocrats."
  • House 2.0: Why sash windows work – "in a critical passage in Part F, the ventilation regulations, there is a reference that says that, when replacing windows, rapid ventilation should not be made worse. Up until now, no one has challenged the assumption that this simply means that the openings should be of similar size. But it transpires that a single opening casement is far less effective at rapid ventilation than a combination of top and bottom openings."
  • Sustainability in practice: Carbon profiling | Design details | Architects Journal – "Sturgis carries out carbon profiling using a bespoke software program that measures the embodied carbon of a building over its lifetime to ascertain its whole-life carbon footprint. Part L requires a calculation of operational energy-use, the Building Emission Rate (BER), which is calculated in kgCO2/m2/year. Carbon profiling uses these same units to measure Embodied Carbon Efficiency (ECE), including allowances for the demolition and transport associated with the building. The total annual carbon cost of a building is the sum of the BER (operational energy) and the ECE (embodied energy).
    Each component of a building is analysed. For example, an aluminium panel and glass cladding system can be compared with a concrete panel and glass cladding system. The concrete system uses about 20 per cent less carbon to construct than the aluminium and will last approximately two to three times longer. Therefore, the ‘carbon cost’ over time is significantly less for concrete than for aluminium."
  • Should aesthetics be part of BREEAM? | Zerochampion – Guest post from Benjamin Kinch: "no matter how energy and water efficient a building may be, it becomes a waste of resources, a potential detriment to the community and environmentally damaging if no one wants to occupy it."
  • Hallmarks of a sustainable city | Publications | CABE – "Hallmarks of a sustainable city sets out the practical and policy responses to climate change that CABE believes are needed to ensure our towns and cities are geniunely sustainable places."
