Links for December 11th through December 17th

December 18th, 2009

These are my links for December 11th through December 17th:

  • Is global warming unstoppable? – Another nutty theory or not?: "Garrett says his study's key finding "is that accumulated economic production over the course of history has been tied to the rate of energy consumption at a global level through a constant factor."
    That "constant" is 9.7 (plus or minus 0.3) milliwatts per inflation-adjusted 1990 dollar. So if you look at economic and energy production at any specific time in history, "each inflation-adjusted 1990 dollar would be supported by 9.7 milliwatts of primary energy consumption," Garrett says….
    "Economists think you need population and standard of living to estimate productivity," he says. "In my model, all you need to know is how fast energy consumption is rising. The reason why is because there is this link between the economy and rates of energy consumption, and it's just a constant factor.""
  • Kevin McCloud is a Big Hit at TGR/RIBA Conference – "The challenge of combining sustainability and conservation issues were thoroughly debated at the conference with input from conservation officers, architects and engineers. Some questioned the need to debate this issue when there are ‘only’ 380,000 historic buildings in the UK – perhaps we should be concentrating on the many thousands of non-historic buildings that are below current standards of sustainability.
    Others wanted to discuss what should be tackled first and what makes most carbon sense. The contrast between the photovoltaic panels at the nearby Heelis project costing £450,000 and only contributing 10-15% of the building’s electrical needs and Kevin McCloud’s modest but effective eco-refurb of a terraced house in Manchester reducing carbon emissions by over 30% but only costing just over £2,000 could not have been sharper."
  • ‘Sustainability’ is a dangerous mirage – Building Design – Owen's on top form: "It’s the very term “sustainability”, which has enabled even Dubai to present itself as if it is touching lightly upon the earth, that is at fault. What exactly is it that we want to “sustain”? Humanity? Nature? Capitalism? As a slogan it’s as awful as “save the planet”. The planet is safe, it’s we who are in danger.
    The problem with the rhetoric of sustainability is that, as a buzzword, it serves to fill the ethical void in the apocalyptic capitalism of the last 30 years. So, we get sustainable supermarkets, green-roofed car parks, carbon neutral desert cities, all of which are a kind of architectural offsetting as moronic as its economic equivalent. A hundred new industrial towns can have the mirage of Dongtan projected onto them. The recent demise of the British “eco-towns” is the pettier version of the same failure."
  • Controlling dew point – 2009-11-19 10:00:00 | Consulting-Specifying Engineer – Excellent article (ASHRAE/US bias) which explains the principles of designing to dew point rather than relative humidity: "Not so long ago, HVAC designers did not have to be especially concerned with humidity. With plenty of cheap energy, the industry could afford to wallop the air with heavy-duty cooling to dry it, then fry it with reheat to keep it from freezing the occupants."
  • Building4Change : European research gives blueprint for social sustainability – "Tools, instruments and metrics to foster sustainable communities are biased towards environmental sustainability, a European research project has found. The research, carried out by Oxford Institute for Sustainable Development, provides a blueprint for policymakers on incorporating social sustainability into European urban redevelopment initiatives.
    The report recommends greater integration of socially responsible investment and local authority indicators, alongside increased investment in data gathering to improve understanding of social sustainability. It highlights valuable monitoring systems such as the FootprintR sustainable investment policy, created by developer Igloo"
  • Abu Dhabi to set school building eco standard – Building – "A new sustainable building standard is being developed for Abu Dhabi's schools.
    The system is being drawn up by Estidama, the organisation behind the emirate's local sustainability code for the the Abu Dhabi Education Council."
  • Futerra Sustainability Communications – leading thinking – Another great guide to communicating sustainable futures from Futerra: "In this guide we argue that climate change is no longer a scientist's problem, it's now a salesman's problem. We call upon government spokespeople, climate campaigners and business advertisers to stop selling visions of hell. Instead we must all create and sell a new vision of a' low carbon heaven'.
    This guide is a new approach for us. Most of our previous thought leadership has been very practical – this is stronger, more opinioned and more controversial. There's still a lot of guidance and original research. But we're not pulling our punches."
    From the report: "Dates, percentages and figures come in action plans, not visions. A 20% cut by 2020 isn’t a vision, it’s a target. Put all the targets together and imagine what the world would be like if we met and exceeded them: that’s a vision."
  • Land Securities chief executive accuses Government of lacking courage on sustainability – Modern Building Services – "On the need to dramatically improve the poor energy efficiency of the UK’s existing building stock, he said, ‘Unlike in the USA, the UK always seems to have a reluctance to use carrots and sticks in the tax system to drive behaviour and redirect capital investment. There is good evidence that tax allowances change investment decisions — and these allowances can be temporary.
    ‘I would certainly advocate a much higher level of Enhanced Capital Allowances for investment in energy-saving plant and building adaptations. However, I think the simplest route may be to use the property rates system to reward those who occupy energy-efficient buildings .’"
  • Leeds given more power over regeneration – Building – "Rosie Winterton, minister for local government, has signed a programme to give Leeds and its regions more power over housing, planning and regeneration.
    The Leeds City Partnership pilot programme brings together 11 councils, regional partners and central government to create a devolved housing and regeneration board."
  • Building4Change : New plant produces energy by mixing fresh water and sea water – "World's first osmotic plant opens, but commercial version will not be available for several years.
    European renewable energy producer Statkraft this month opened the world's first power plant generating energy by mixing fresh water and sea water in Norway.
    The energy is based on the natural phenomenon of osmosis, the transport of water through a semi-permeable membrane. When fresh water meets salt water, substantial amounts of energy are released, which can be used to generate power.
    At the osmotic power plant, fresh water and salt water are guided into separate chambers, divided by an artificial membrane. The salt molecules in the sea water pull the fresh water through the membrane, increasing the pressure on the sea water side. The pressure equals a 120 metre water column, or a significant waterfall, and can be used in a power generating turbine."
  • Design Activism: Coming across chemicals: in plastics and in schools – "the main problem with the chemicals is that not enough of them have been properly tested for health effects, and the result is that we only regulate chemicals that we know about. A classic example is BPA, a chemical additive found in bottled water containers, baby bottles and the like. Last year mounting evidence about adverse health effects from BPA caused it to be withdrawn from the market.
    The long term solution to this problem is hatching in the Green Chemistry movement, which is aiming to put the burden of proof of safe chemicals on the manufacturers. Currently a chemical is innocent until proven guilty, however, there are simply too many chemicals and, based on the evidence we do have, no reason to assume their innocence. Proposed green chemistry policies also recognize that health problems might arise for interactive, multiple exposures."
  • Ben Casnocha: The Blog: 10 Easily Implementable Life Problem-Solving Strategies – Some great thoughts on procrastination from Ben: ""Can I fail at this?" It's like Raymond Chandler said: there is no success without the possibility of failure. Therefore, something I can't fail at is also something I can't succeed at. I can fail at conducting an interview, writing an essay or making a video. I can't fail at meandering around the internet in search of "neat stuff to read." In a recent tweet, I defined procrastination "the temporary displacement of tasks at which it is possible to fail with tasks at which it is not possible to fail." I suspect I'm less far off the mark than ever, especially regarding why procrastination is not a productive tendency."
  • ippr – Institute for Public Policy Research – Left foot forward – "Increased birth rates and an ageing population, coupled with a fall in net immigration into the UK means that natural change, births and deaths – is now responsible for a greater component of the UK’s population increase, rather than immigration.
    But what should a progressive UK population policy look like? It will have to deal with issues such as family size, retirement age, population distribution across the UK, as well as immigration control.
    Attempts to restrict immigration to a zero net immigration level… will have major economic consequences. At present younger immigrants make a greater fiscal contribution than do the older UK-born population. Big restrictions on labour immigration would result in higher taxes, among other outcomes. Fiscal deficits could be alleviated if everyone worked longer… Family impacts on population size, but how would British adults react to being told to stop at two children? What incentives could be offered to families who stop at two?"

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."

Links for November 14th through November 19th

November 20th, 2009

These are my links for November 14th through November 19th:

  • Welcome to amazonails – Enerything you ever needed to know about straw bale building.
  • Footprint » Common carbon language – "The ‘Common Carbon Metric’ will be piloted by the leading green building rating tools and made available to anyone dedicated to promoting the understanding and development of a low-carbon built environment. The real impact of this initiative lies in the detail which has yet to be announced, but it is an indication of the growing consensus about the role the built environment can play in mitigating climate change."
  • Publications – News & Publications | BioRegional: solutions for sustainability – via Hattie at AJ, I find that BioRegional are making lots of their reports free. Will be interesting to read the One Planet Communities and compare to BREEAM, LEED and Estidama. Communities (rather than buildings) will be the buzzword for 2010. Unfortunately Pooran Desai's book is not free, but can be ordered from Amazon.
  • marklynas.org | Closed because of geoengineering works – Mark Lynas on geo-engineering (something I'm really not comfortable with): "Geoengineering deeply divides scientists and environmentalists. Should we really consider spraying sulphates into the stratosphere, planting artificial trees across deserts or dumping iron filings in the Pacific as legitimate options to cool down our planet? Kruger, whose preferred solution involves spreading billions of tonnes of lime in the oceans (see cquestrate.com), likens the approach to having an airbag in a car: it’s better not to crash, but also sensible to insure against the risk that the worst will happen. Plus, “the time to design an airbag is before you are skidding on ice”."
  • Predicted vs. Actual: Closing the Gap – "Marcus Sheffer, chair of LEED’s Energy and Environment Technical Advisory Group (TAG), shared some ideas under consideration for the next update to the rating system slated for 2012. The group is closely looking at LEED’s energy credits so that energy simulations more accurately predict performance. For example, the TAG is looking at ways to encourage modeling earlier and more frequently in the design process. “We need to change the practice of validation modeling at the end of a project,” said Sheffer. “We need more iterative modeling.” "
    Interesting comment after the article – can we *really* predict performance?
  • Three older houses to be Passivhaus retrofitted – "An architects practice is being funded by the Technology Strategy Board to undertake design and feasibity studies into a proposed scheme to retrofit three empty houses to Passivhaus standard. The Retrofit for the Future competition is designed to address the challenge laid down by the government's target of reducing greenhouse gas emissions by 80% by the year 2050."
  • Announcing Living Building Challenge Version 2.0 — ILBI – For those unfamiliar with ILBI, think of it as uber-LEED: "Version 2.0 of the Living Building Challenge expands its focus to local food production, unrestricted access to nature, no gated communities and other equity issues."

October 23rd, 2009

These are my links for October 20th through October 21st:

  • Brand vs. Lovins On Nuclear Power | WBUR and NPR – On Point with Tom Ashbrook – Lovins argues against nuclear: "Nuclear is about the most expensive and slowest thing you can build. And I don’t think it’s true you need to build everything. You can’t afford to build everything. You need to choose the best buys for your goal, just as in assembling a financial portfolio you don’t stuff it full of one of everything on the market. You figure out the diversified set of assets that will best meet your investment objectives. If you buy something really expensive and risky, that actually makes your portfolio perform worse because you didn’t get to buy stuff that would have performed better".
  • Insolvency increase suggests recovery will start with a W – Leeds University Business School – Doom from my MBA alumni newsletter: "Ten months ago the message of the Monetary Policy Committee was that the recession would be short but sharp, a V shape. As economic statistics started to catch up with real events this view had to change and the V became a U the recession would be deep and more prolonged than originally anticipated. Our data suggest that the shape is likely to be a W. Company insolvencies translate into unemployment and the now rapid rise in unemployment in a stagnant economy puts further pressure on indebted and financially stressed households and further strain on the banks. This will potentially incubate another crisis in the economy by the late autumn, hence the double dip (W). It is difficult to envisage how a recovery will emanate from Britains debt-bloated economy. It wont come from consumer spending nor a housing boom. It might come from Britains culture of creativity, innovation, technology and enterprise…"

August 14th, 2009

These are my links for August 7th from 14:13 to 14:37:

  • Wales waives planning for micro-renewables – Building – "The changes will enable householders to install certain types of domestic micro-generation equipment, including solar thermal panels, ground and water source heat pumps, and flues associated with biomass and combined heat and power systems, on or within the boundary of houses and flats, subject to certain criteria.
    The measures go further than the authorities in England by allowing standalone solar panels up to the boundaries of properties, provided they satisfy certain height and highway criteria"
  • FT.com / World – Sceptic switches tack – Lomborg (much maligned anti-hero) is back and distancing himself from the climate change deniers. He's still going to cause waves though, on Copenhagen : "“Getting a deal will undoubtedly be very hard, but if we get better ideas on the table that are cheaper and more efficient [than emissions cuts for the rich] then there is a greater chance that we will succeed,” he said."

July 31st, 2009

These are my links for July 26th through July 27th:

  • International Green Construction Code (IGCC) Now in the Works| News | Architectural Record – International in the same way the World Series is a global baseball competition: "On June 29, the American Institute of Architects, along with the International Code Council (ICC) and the American Society for Testing and Materials (ASTM), announced their intent to create an International Green Construction Code (IGCC).
    The new code aims to cover all aspects of sustainability in the built environment, from roofing to ventilation strategies, drawing from existing codes and standards to create one universal code. The code will apply to new construction and renovations. “We hope this will bring all of the separate efforts together and put them under one umbrella to make it easier for jurisdictions to know what they are adopting,” says Adolf Zubia, ICC board president."
  • CBI climate change progress tracker. CBI on climate change. – Climate change remains one of the most critical issues affecting the UK, but in tough economic times it is at clear risk of slipping down the political agenda. Urgent action to cut emissions must be delivered if we are to hit government emissions reduction targets, ensure a future independent supply of energy, and manage rising energy costs.
    The CBI’s Climate Change Tracker is a tool developed by the CBI to track progress against the priorities set out in the CBI’s 2007 climate change report, Climate change: everyone’s business.
    The Tracker benchmarks the progress of the priorities for action set out in the report, focusing on the immediate decisions and delivery needed up to 2010.
  • Dubai development may be down, but it’s not out – Los Angeles Times – Fascinating and scary article on Dubai: "In the heart of most cities, the biggest piece of land that a single developer is typically able to control is one square block. …In Dubai, whole districts of the city, many covering dozens of square blocks and hundreds of acres, have been given over to single developments. Seeing architectural diversity within any project as a threat to the bottom line, their creators usually hire a single firm to design them around a recognizable theme…
    The result is a surprising twist on the privatization of cities like Los Angeles, where public space is notoriously scarce. In the privatized city, as the well-known critique goes, people aren't forced to mix with people who are different from themselves. They are hidden from that interaction inside their private cars and gated developments. … In Dubai, remarkably enough, the same is true for buildings, which tend to cluster together with other pieces of architecture just like them."
  • Property’s Quangocracy – Property Week – Excellent dissection of the RDA's and their spending. MIPIM anyone?
  • Charter of the New Urbanism | Congress for the New Urbanism – My Jane Jacobs obsession has lead me to the doors of New Urbanism and their charter. With LEED-ND and BREEAM Communities rearing their heads, time to get to grips with New Urbanism and what the future holds…
  • Frank Gruber: New Urbanism: Very Misunderstood – "New Urbanism, although it has antecedents in mid-century voices (such as that of Jane Jacobs) …is a movement that arose in the 1980s among architects upset not only with the decline of the quality of the built environment but also with the failure they perceived of the profession of architecture to pay attention to the spaces between buildings and the larger urban or regional context…
    New Urbanists are attacked from both sides of America's cultural divide. Chances are, if you mention New Urbanism to group of forward thinking, contemporary design professionals, whether architects or planners, they will roll their eyes. To them New Urbanism, …is a facilitator of sprawl, not a solution. …New Urbanism is hopelessly nostalgic.
    But if you find yourself among a group of conservatives or libertarians, … you'll just as likely unleash a denunciation on the grounds that New Urbanism aims to thwart the natural desire of Americans to live in a single-family house on a cul-de-sac."
  • Media library · Town and Country Planning Association – "Leading planning and housing charity, the Town and Country Planning Association(TCPA) will celebrate its 110th AGM today by publishing a Manifesto for the 21st Century. The Association’s vision – Towns and Countryside for a New Age of Challenge – sets out a new set of aspirations which directly address today’s challenges of climate change, globalisation and social justice.
    The TCPA’s Manifesto comprises four main elements: choice and diversity; cities and the larger task; a revitalised countryside; and networks of cities, towns and villages."
  • The Effect of the Recession on Partnering in the Construction Sector – Excellent presentation from Don Ward, which he presented at the AEC networking meeting at the Building Centre last week. Slides 31/32 hold key messages for me. A lower price for the client does not necessarily have to eat into our profit margins (and in fact, shouldn't – we all need to make money).
  • Real Time Carbon – I love this – I have a great deal of time for anything coming out of AMEE : "Until now, anyone trying to understand the carbon impact of the electricity they use has only had a single static Government conversion factor. The factor – currently 527 grams CO2 per kWh of electricity – is updated only a few times a year.
    The standard figure is based on a number of assumptions about the mix of energy used to generate electricity – the "generation mix". It tells consumers nothing about the carbon intensity of electricity at a given time.
    Real Time Carbon wants to help energy users see the real-time carbon intensity of electricity so they can avoid consuming at times of high emissions. We look forward to a time when appliances, buildings and factories automatically manage demand according to the carbon being released."
  • Our Seven Commitments – Royal Town Planning Institute – Interesting work from RTPI, but it feels a little late? Interested to find out how they do with no.1, behavioural change, and good to see it isn't a "cast-in-stone" mainfesto : "The seven commitments are supported by a living and continuously improved action plan that will deliver practical outcomes, benefiting communities at the global and the local scale."
  • U.S. Energy Secretary Steven Chu: “Global Warming Is the Greatest Challenge Facing Science” « The Dirt – "In the case of energy-efficient buildings, Chu argued local knowledge drives local building development, and needs to be updated to ensure best practices in energy-efficient buildings quickly go global. ”Buildings are local. We don’t ship buildings to Denmark.” He described the type of knowledge needed for creating energy-efficient buildings as a sort of “hands-on,” practitioner’s knowledge –”it’s like a gardener’s craft or like those who know how to cook well.” Still, he thinks it is possible to “teach each other how to capture carbon, how to create more energy-efficient buildings.” To those who argue that any intellectual property (IP) transferred overseas should be protected, Chu added “it’s not about intellectual property (IP), it’s about people.” He also argued that the case for energy efficient buildings is economic — highly energy-efficient buildings can reduce current energy consumption by four-to-five times, putting “more money into people’s pockets.”"
  • Ch 13 Page 79: Sustainable Energy – without the hot air – From David MacKay's excellent book:"“it’s better to drive than to walk.” Whether this is true depends on your diet. It’s certainly possible to find food whose fossil-fuel energy footprint is bigger than the energy delivered to the human. … According to a study from the University of Exeter, the typical diet has an embodied energy of roughly 6 kWh per kWh eaten. To figure out whether driving a car or walking uses less energy, we need to know the transport efficiency of each mode. For the typical car …, the energy cost was 80 kWh per 100 km. Walking uses a net energy of 3.6 kWh per 100 km – 22 times less. So if you live entirely on food whose footprint is greater than 22 kWh per kWh then, yes, the energy cost of getting you from A to B in a fossil-fuel-powered vehicle is less than if you go under your own steam. But if you have a typical diet (6 kWh per kWh) then “it’s better to drive than to walk” is a myth. Walking uses one quarter as much energy."
  • DOE: Building Energy Codes – News Item – "The decision to create the joint publication resulted from the recent legislation passed by the U.S. Congress, known as the American Recovery and Reinvestment Act of 2009 (ARRA). The Act establishes an energy efficiency goal of 90 percent compliance with the 2009 IECC and Standard 90.1-2007 in all 50 states by 2017. In establishing this goal, the Federal legislation recognizes the 2009 IECC and Standard 90.1-2007 as the energy efficiency benchmarks for residential and commercial buildings.
    Because the ICC and ASHRAE documents complement each other, publishing them in one book benefits architects, designers, engineers, and code officials. It makes it easier to choose between design options, and helps make sure new and renovated buildings are in compliance with the latest references and local building safety codes."
  • Bad British Architecture: BLAR MHOR HOUSING IN CAOL, FORT WILLIAM BY ARCHIAL FOR LORNE DEVELOPMENTS – Very quickly, a firm favourite on my blogroll. Ghost of Nairn in acerbic form as usual: "One helpful rule of thumb, from Nairn to you. When someone presents a masterplan with a perimeter of a line of trees, it means they're trying to hide something. Do not trust these people."

These are my links for July 2nd through July 8th:

  • Woobius Scribbles — Bottom-up collaboration in the construction industry – Excellent post on collaborative working by Woobius and the curse of email:"You know that feeling. You’ve just set up the best collaboration system ever. You have all the processes documented and approved. Everyone’s agreed to use the system. Things couldn’t be better. Then, the project kicks off and there comes that sinking feeling when you realise that everyone is bypassing your carefully tuned system.
    Everyone is sending emails instead."
  • If zero carbon is the answer then just what was the question? « isite – Martin has an excellent rant and takes on Passivhaus amongst other issues pertaining to zero carbon: "Passivhaus is emerging as the aspirational darling or solution. But what is the true embodied energy of passivhaus, in particular the massive amounts of insulation, sheeting and duct tape? Passivhaus will reduce energy requirements and costs. Excellent. But I would love to see the payback time on the total and higher than normal embodied energies and waste."
  • Tellytubby land: BedZed revisited – Building – Fantastic review of BedZed 7 years on. I was fully aware of the situation with the CHP, but less so with the allotments and car use issues. A long article, but very worthwhile reading.
  • Climate change odds much worse than thought – MIT News Office – More doom, but presented in pretty roulette wheels. I ought to stop reading all this doom, but am strangely compelled to keep checking for confirming evidence. Behavioural economists, make of this what you will.: "The new research involved 400 runs of the model with each run using slight variations in input parameters, selected so that each run has about an equal probability of being correct based on present observations and knowledge. Other research groups have estimated the probabilities of various outcomes, based on variations in the physical response of the climate system itself. But the MIT model is the only one that interactively includes detailed treatment of possible changes in human activities as well – such as the degree of economic growth, with its associated energy use, in different countries."
  • The orders figures and public spending fears point to industry chaos ahead – need it be so? (Brickonomics) – I'm in broad agreement with Brian on this:"What firms should be doing now is assessing what they are good at and what they are not good at, what makes them profit, what costs them time and resources unprofitably.
    They should focus on quality of earnings not volume of earnings.
    They should focus effort on what they are good at and judiciously shed the operations that are weak….
    That however does not alter the reality that this recession will be cruel and that the industry has no choice but to retreat. Turnover overall must fall. Competition does need to be taken out of the market.
    It is better that firms recognise their weaknesses and retreat from them than seek to bid unrealistically against those better placed.
    The worst of all outcomes would be to lose good firms because of the woeful bidding by weak operations desperate to win work at any price."
  • We don’t know what is coming next – so get ready – The Regeneration Blog – Jackie's advice on getting ready for a potential change in administration: "But in the meantime, my current advice is this: you know not what is coming next, so get as ready as you can. Have a total clear out (in every sense), trim down, strip back everything and establish your priorities.
    Swot up on localism and reconnect with your bottom-up roots. If you are able to deliver decent outputs (notably jobs or homes) you will be safe even if – or perhaps especially if – as we suspect, the RDA's get wiped away and their responsibilities are given to County Councils and the like. "
  • Sustainable Design Tools Exhibited at AIA 2009: AECbytes Feature Article – Excellent review of the latest 'sustainable design' software tools available on the market, including Ecotect (aligned with Autodesk and therefore AutoCAD – very popular with architects), IES (my favourite) and TAS and Hevacomp (which are now both owned by Bentley (the home of AutoCAD rival Microstation). Whatever happened to Cymap? Seem to have been left behind…
  • PlanningBlog: When did everyone get so cynical? « – "Regeneration is quite often seen as big business riding roughshod over local people’s wishes. It’s eyed with suspicion and written off as ‘ a waste of taxpayers money’ before it’s even come out of the ground.
    This all ties in with the wider anti-politician backlash currently sweeping the country. Politicians and anyone in authority are seen as ‘out to line their own pockets’ and anything they propose or champion is therefore, by association, a bad thing.
    Of course we should question authority and challenge things we don’t agree with but whatever happened to taking something at face value? A much needed regeneration of an area might actually be just that, not a conspiracy or an attempt to get one over on the general public.
    I’m not sure what the answer is to this. … Perhaps the problem is with the politicians themselves and only political reform can ‘reconnect’ and re-build trust between the people and those in authority."
  • Government ends energy bulbs scheme – The IET – Some sensible news: "Power companies will no longer be able to mail out millions of energy-saving light bulbs to meet their targets to cut greenhouse gas emissions from homes.
    The Department for Energy and Climate Change (Decc) has announced changes to the Government scheme requiring energy suppliers to cut emissions from homes, including an end to the direct mail out of low-energy light bulbs by January 1, 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 21st through April 27th

April 28th, 2009

These are my links for April 21st through April 27th:

  • NGS GreenSpec – Materials – Embodied energy – Data on embodied energy is notoriously difficult to find. This is a useful source: "The figures included in the following table are a much-shortened and abbreviated adaptation of a survey published by the Sustainable Energy Research Team (SERT) of the University of Bath. The survey, ‘Inventory of Carbon & Energy (ICE)’ V1.6a, was compiled and written by Prof. Geoff Hammond & Craig Jones, 2008. The full detailed survey, complete with original data, methodology and notes, is availablefrom www.bath.ac.uk/mech-eng/sert/embodied/
    The figures are based on a ‘Cradle-to-Gate’ analysis of publicly available information."
  • BSD launches wiki site – Building Sustainable Design – "The BSD Project wiki allows you to upload details of projects, images and design team information to our project database.
    You don’t have to know every last detail about a particular project, just log in and fill in the bits you do know then encourage other members of the project team to upload information on the aspects of a scheme for which they were responsible.
    Like Wikipedia, the BSD site is a database open to everyone, to contribute or scrutinize and over time we hope the wiki will grow into a valuable resource of contemporary project design."
  • ACE – CFLs won’t save much energy if they stay in the kitchen drawer – Andrew Warren on all those unsolicited lightbulbs. Not only unsolicited, but often packaged in boxes too big to go throught the letterbox, requiring an extra car trip to the post depot. *sigh*
    "Since 2002, the energy companies have distributed 262m light bulbs. That amounts to an average of over eleven CFLs for every single household in Britain. Nonetheless I keep meeting people who have never received any such largess. Bearing in mind the large number of studio and single-bedroom flats around, with far fewer than eleven light sources, that ought to mean that some households must have got at least a couple of dozen.
    Are they all installed? Amazingly, nobody seems to know. There is no requirement for anybody to keep tally on which addresses these 262m bulbs have gone to, let alone to establish whether they are being put to use. If ever there was a need for a sample survey of existing homes, this must surely be it."
  • Recovery soon for construction? (Brickonomics) – "Clearly the wider economy as measured by GDP has a major impact on construction output, but the link is neither linear nor direct. … construction is a series of mini-industries with growth cycles that are out of phase.
    When you aggregate the various cycles of construction together the effect is to elongate the overall response rate to outside signals….. So while housing is moving up, commercial may well still be moving down before rising later.
    The pattern is further muddled by the heavy influence of public spending, which accounts for about a third of all work. This can operate counter-cyclical to the private sector, dulling the up and down movement and reshaping the V towards a U.
    And it is this spending that currently poses the most concerns regarding the shape of the construction recovery.
    There is a real risk that public spending on construction will take an L-shaped path in the near future as the Treasury seeks to balance its books."
  • James Randerson: To stop a climate catastrophe we must first believe we can make a difference | Environment | guardian.co.uk – "Far from over-playing their hand to swell their research coffers, scientists have been toning down their message in an attempt to avoid public despair and inaction."
  • scottberkun.com » Where do your ideas die? (With a bad illustration) – This sounds familiar (from my days back in large engineering consultancies): "Executives often do this flinchy sort of thing and it’s big news at many corporations to start “idea programs” to encourage people to submit ideas. These programs are launched, ideas are submitted, and there is much rejoicing. But little change.
    The reason there is little change is that idea inputs were never the problem. The bottleneck was further upstream. Crowdsourcing, brainstorming, mindmapping, and the dozens of other techniques people obsess about help create early idea volume, but do little to help the curators, the people who winnow down the hundreds of ideas down to dozens, and dozens down to a handful.
    It’s much more useful to study where the bottlenecks are, when and why new ideas are killed, and who the people are that are killing them."

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."
