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 October 30th through November 5th

November 6th, 2009

These are my links for October 30th through November 5th:

  • GEO DYNAMICS – How sustainable are heat pumps? -:- Construct Ireland – Great, but long, article on the pros and cons of air source heat pumps. Level of detail is just right, with plenty of graphs and good argument.
  • BSRIA review of NG Bailey’s Solais House – Great review of Solais House. I hadn't realised that it was a spec office before, having seen David Frise present it recently. That explains why it's aesthetically…dubious. Despite this constraint, promises to be a great example – although we await the POE results.
  • A place for PVC in a sustainable world? | Forum For The Future – Fascinating article on PVC. Still not convinced about the green guide rating of A for PVC windows, but things are getting better: "It’s not the first time that TNS has wrestled with the issue. It originally grappled with the stuff in 2000, when, with the support of the UK Environment Agency, it investigated whether PVC could have any place in a sustainable society. The answer was a cautious ‘yes’ – providing the industry addressed some of its most pressing challenges."
  • Sir Nicholas Grimshaw – People – Dwell – Great quote from Grimshaw on sustainability: "You’ve got to do a bit of lateral thinking on these green issues. It’s quite important to be pragmatic. The one thing we have to watch very carefully is polarization"
    Unusual to find a pragmatic architect – consultants and engineers usually much more pragmatic as they don't play the same zero-sum game as architects are forced into.
  • Footprint » You should have been at the RIBA tonight… – Intriguing – anyone know anything more on Bill's views?: "Dunster also made a strong plea on behalf of the Code for Sustainable Homes, calling it ‘an enlightened piece of legislation in danger of being dumbed down by the UK-GBC and the ZeroCarbonHub.’"
  • News : NDS – From Mandelson's Hinto Engineering Lecture: "Snow didn’t use the term, but he was angling at the idea that Britain was becoming a scientific knowledge economy. This is certainly the case now. We need to understand more clearly than ever the way in which our pure science and applied science underwrite our prosperity, not least so we can strengthen their contribution to economic growth.
    The wider costs of any failure to do this are very high, both for our own economy and society, but also globally. Snow was worried about how a scientifically illiterate society might fail to feed the expanding populations of the developing world. That concern is still very much with us, and to it our society would have to add the massive problem of decarbonsiation and the management of our environmental impact on the planet. "
  • Constructing Excellence in the Built Environment » Blog Archive » Never Waste a Good Crisis – Another report added to my 'must read and comment pile': "Government, as a client, needs to understand the enlightened thinking that better and more intelligent designs improve patients’ recovery in hospitals and learning outputs in schools. So, rather than reduce the number of schools and hospitals being built, it must sponsor smarter and more productive solutions and reduce the amount of money wasted on the procurement process. For Government as a policy maker, the challenge is to create an environment that incentivises innovation and speeds up the modernisation process."
  • Thoughts on Copenhagen: Nicholas Stern | News | Architects Journal – Good series of interviews from Hattie in the AJ, on COP15, including this one from Nick Stern: "Energy consumed in the construction and operation of buildings is responsible for more than one third of total energy use. According to the fourth assessment report by the Intergovernmental Panel on Climate Change, published in 2007, the building sector has great potential for reducing greenhouse gas emissions.
    It concluded that the energy consumption of new and existing buildings can be cut between 30 and 50 per cent without significantly increased costs.
    Architects, together with other built environment professionals, have the strategic and technical skills to deliver buildings that both lead to lower emissions and withstand those impacts of climate change that are now inevitable. With existing technologies, these buildings are now affordable. New technologies are constantly being created. What is required is the vision, leadership and commitment to make a low-carbon future reality."
  • Thoughts on Copenhagen: Pooran Desai | News | Architects Journal – The run up to COP15 has started, with this snippet the most interesting thing I found in AJ's recent piece, from Pooran Desai: "To achieve effective change, we need elegant solutions and a sensible systems-based approach to zero carbon; for example, recognising electricity as a pooled resource and not unnecessarily converting buildings into power stations. Land use is as critical as carbon emissions."

Links for October 24th through October 29th

October 30th, 2009

These are my links for October 24th through October 29th:

  • Campaign calls for strengthened renewables policy – PlanningResource – "Ministers pledged in July to update the guidance in PPS1 and PPS22 to "ensure that they set a clear and challenging framework for delivering energy infrastructure consistent with national ambitions."
    TCPA energy policy manager Kate Henderson said: "The planning system can play a key part in tackling climate change by ensuring we get the right amount of renewable energy, by encouraging carbon zero development and by shaping development which reduces the need to travel by car.
    "But despite some excellent rhetoric, much of the planning system is still locked in the age of stupid. It allows carbon intensive development and often refuses real solutions to climate change such as renewable energy projects."
    Ministers plan to publish a draft new PPS on climate change and renewable energy by the end of the year, with the aim of adopting new guidance before the end of the current parliament."
  • Energy standards for homes to fall short of Passivhaus – Building – The death knell for CSH?: "The Hub has proposed a radical overhaul, with builders asked to meet an annual energy output per square metre depending on building type, rather than satisfy the points-based system operated by the code."
  • UK must replace 12 million non-condensing boilers by 2022 says CCC – CCC recommends that: "Non-residential buildings achieve a minimum Energy Performance Certificate rating of F or higher by 2020."
  • SuperFreakonomics Ignores the Business Case for Sustainability – Andrew Winston – HarvardBusiness.org – I have largely missed the Superfreakonomics geo-engineering debate – this is a good starting point. Hoping to catch Levitt and Dubner at LSE later this month – some pointed questions will be ready…
  • Statistics watchdog hits out at government emissions claim – PlanningResource – "The government has been exaggerating the UK's success in cutting carbon emissions, according to the UK Statistics Authority.A Department of Energy and Climate Change claim that carbon emissions were 12.8 per cent lower in 2007 than in 1990 is "unsatisfactory" and falls short of the government's code of practice for official statistics, said the watchdog's chairman Sir Michael Scholar.In a letter to the Commons environmental audit committee chairman Tim Yeo, he said nearly a third of that fall is made up of carbon credits in the EU trading scheme and do not represent real
    cuts. The fall is 8.5 per cent without the credits."
  • RIBA to bin ‘outdated’ fee scale graphs | News | Architects Journal – So everyone will be laminating their old copy then? : "The RIBA is to drop its fee scale graphs in the latest edition of A Clients Guide to Engaging an Architect.
    The loss of the graphs, which featured percentage fees based on independent cost survey data, marks the demise of the institutes once compulsory fee scales abolished as mandatory in 1982 and as recommended scales in 1992.
    The RIBA maintained the revised guide would still contain concise written advice about how practices calculate fees and structure payment options."
  • PassivHaus UK – My current obsession with U-values unearthed this gem: "Please note that whilst PHPP includes a worksheet for calculating the U-values of components it is not sufficiently accurate for demonstrating compliance against UK building regulations as it does not adhere to BRE document Conventions for U-value calculations (2006 Edition). Whilst the U-value calculator incorporated within PHPP is used as a basis for certification purposes designers are recommended to use suitable U-value calculator software packages for demonstrating UK building regulations compliance and undertaking SAP calculations, suitable software includes BRE's own U-value calculator, or other software packages such as BuildDesks free U-value calculator."
  • Climate Change (Political Response): 21 Oct 2009: House of Commons debates (TheyWorkForYou.com) – Andrew Stunell (Lib Dem) reminds us all of a forgotten Bill during last week's 1010 debate: "In 2004, I was fortunate to be top of the ballot and able to introduce the Sustainable and Secure Buildings Bill in this House. I wish to say to the House and to the Minister that there have been missed opportunities as a consequence of the Government not choosing to implement what was in that Bill, which allowed them to amend the building regulations to take account of the sustainability and efficiency of buildings."
    Worth reading the entire debate (despite the outcome)

Links for October 5th through October 7th

October 9th, 2009

These are my links for October 5th through October 7th:

  • Energy Efficiency Partnership for Homes – Partnership Publications – EEPH/CLG report: "This report presents results and findings of the joint EEPH (Energy Efficiency Partnership for Homes) and Department for Communities and Local Government (CLG) project to study the levels of compliance with Part L of the Building Regulations.
    Specifically, it presents the results from a study of compliance for new dwellings built since April 2006 in accordance with Approved Document L1A (2006). The results for the full sample for the 2nd Phase of the project are presented"
  • The future of green building in China – ClimateChangeCorp.com – Interesting (long) article on green building in China: "Perceived high cost is another barrier. When a World Business Council for Sustainable Development survey in 2007 asked the real estate developers and building professionals worldwide how much more they thought green buildings cost than normal buildings, the Chinese respondents said they thought certified green buildings cost 28% more. They were unaware that in China the average extra cost for a LEED certified building has been 3-5% more. This figure is similar to the global average incremental cost for LEED certified buildings.
    Lewis says as long as the Chinese developers have a perception that green buildings cost a quarter more, they will surely not go for green projects."
    China’s green building targets
    * Reduce building energy use in all cities by 50% by 2010 and 65% by 2020 (base year 1980)
    * Top 1000 State Owned Enterprises Programme aims to improve energy efficiency in the largest SOEs by 2010…
  • Target Zero – About Target Zero – AECOM have been commissioned by Corus and BCSA: "The aim of this project is to understand the implications of the UK Government's move towards 'zero carbon' for five steel framed non-domestic building types.
    Target Zero will research and cost options for improving operational energy consumption and reducing embodied energy and other life-cycle impacts. The fully costed solutions generated will demonstrate how to achieve the three highest BREEAM ratings and meet the anticipated changes to Part 'L' of the Building Regulations."
  • Zerofootprint » Communities – Interesting competition to retrofit a post-war, pre-90's concrete building and operate at net zero for a year. Their definition of net zero is on-site NOT community level, and by my reckoning excludes biomass: "All the energy required to power household amenities, cool, heat, and light the building must be provided on a net zero basis. Possible onsite energy systems can include wind, solar, bio-fuel cells (from occupant produced organic waste), hydrogen cells, etc. Energy must be produced by devices located within the building and its nearby property, and cannot be powered by fuel brought to the building. The building can contribute excess energy to the grid and, when necessary, access an equivalent amount, but no more."
  • Passivhaus Windows | GreenBuildingAdvisor.com – I've been slightly obsessed with window u-values recently. This article has a great overview of German vs. US calculations differences and some good suppliers for windows from Canada: "When I interviewed Dr. Wolfgang Feist in 2007, he told me, “The reason for the number which we now use in Europe is the comfort of the occupants. It is a functional definition. During the winter, the coldest surface temperature in the room will be the window. If you don’t have a radiator in your room, the difference between the surface temperature of the window and the mean surface temperature of the room should not be more than 3 degrees Celsius; that’s for comfort reasons.”
    The colder the climate, the more important it is to use U-0.14 or better windows in a Passivhaus building — and not just for comfort. Low U-factor windows are necessary to meet the Passivhaus maximum annual heating energy standard of 15 kWh per square meter."

September 26th, 2008

These are my links for September 24th through September 26th:

  • Fabric Insulation – ways of further raising performance standards for all types of building fabric: BD 2428 – Planning, building and the environment – Communities and Local Government – This report summarises building thermal performance requirements in Denmark, Germany, Switzerland and the Netherlands and classifies them according to the approach taken (elemental unit-based approach, target U-value average heat transmission through the building envelope, heat demand calculation or integrated energy use calculation).
    The regulations are compared to each other and contrasted with United Kingdom building codes.
  • Minister pledges zero-carbon homes definition consultation ’shortly’ – The Government expects to begin consultation on the final definition of zero-carbon homes shortly, planning minister Caroline Flint told the Labour Party Conference in Manchester.
    The minister confirmed that the issue of how the zero-carbon definition dealt with on and offsite green generation remained the most challenging element of the form of words which would be consulted on.
    The fringe meeting heard that Government-commissioned research into the zero-carbon target had highlighted problems over the availability of some of the key technologies and an estimate that the new standards could add between 17 and 24 per cent to the costs of a new home.
    The conference also learnt that the standard would be significantly harder to achieve in high-density, urban infill schemes compared to more large-scale non infill projects.
  • How eco-towns can support living within ecological limits – Cutting-edge principles for the agencies involved in developing proposals for eco-towns have been published by BioRegional and CABE. The report, What makes an eco-town?, defines an eco-town as a place designed to make it easy for residents to reduce their ecological footprint by two thirds and their carbon dioxide emissions by 80 per cent below 1990 levels.
  • Patrick Barkham talks to Tony Wrench about low-impact housing in … – Closure on the Welsh Hobbit house planning controversy: "After a long struggle with the authorities, Wrench got retrospective approval for his home, tucked away in a valley in south-west Wales, via an unusual planning policy experiment in Pembrokeshire. County council and Pembrokeshire Coast National Park planners agreed to allow for low-impact developments on rural land where normal houses would not be considered, as long as they met stringent environmental, economic and social criteria."
  • Environment Agency – Green roof toolkit – GLA green roof toolkit.

My del.icio.us bookmarks for September 11th through September 19th

September 19th, 2008

These are my links for September 11th through September 19th:

  • BREEAM set to cover communities – Building – Unlike existing BREEAM tools, the assessment will take into account regional requirements. Cotter said: “For example, does the development meet the criteria for employment stimulation? It’s about making sure development complements regional local planning requirements.”

    It has not been decided whether the assessment will include existing buildings.

  • Rogers and Foster shun nuclear design framework – Building – “Ethically, we wouldn’t get involved in projects like this. We have a fairly strict constitution set up by Richard [Rogers] which prohibits work on military schemes and power stations.”
  • NHF demands stricter CO2 timetable for housebuilders – Building – Orr said: “Currently, private developers are not being compelled to meet minimum standards on greenhouse gas emissions at all. In fact, they are being allowed to put their profits ahead of the survival of future generations.

    “It's time that ministers legally locked private developers into the same timetable as housing associations. We have long been calling for the government to ensure that from April 2008 all new private homes emit 25% less CO2. And we would like ministers to make certain that all new privately built homes are zero carbon by 2016, at the very latest.

    “Unless the government compels the private sector to meet the same standards and timetable, private companies will simply try to wriggle out of their environmental duties, saying it costs too much.”

  • The Question of Global Warming – The New York Review of Books – "Environmentalism has replaced socialism as the leading secular religion. And the ethics of environmentalism are fundamentally sound. Scientists and economists can agree with Buddhist monks and Christian activists that ruthless destruction of natural habitats is evil and careful preservation of birds and butterflies is good. The worldwide community of environmentalists—most of whom are not scientists—holds the moral high ground, and is guiding human societies toward a hopeful future. Environmentalism, as a religion of hope and respect for nature, is here to stay. This is a religion that we can all share, whether or not we believe that global warming is harmful."
  • OMNIVORACIOUS: Thomas Friedman and Fareed Zakaria: Author One-to-One – via Ben Casnocha, Friedman takes Zakaria to task on the alleged green revolution: "So you'll know the green revolution is happening when you see some bodies–corporate bodies–along the side of the road: companies that didn't change and therefore died. Right now we don't have that kind of market, that kind of change-or-die situation. Right now companies feel like they can just change their brand, not actually how they do business, and that will be enough to survive."
  • Felicity Lawrence: We could slash our CO2 emissions if we ate less meat. What a pity Boris Johnson doesn’t agree | Comment is free | guardian.co.uk – Whilst the article is good, the reason I am flagging this one is the fact that McD's are the Olympics 2012 official caterer. Cognitive dissonance, anyone?
  • TALL BUILDINGS OFFER ECONOMIC BENEFITS, SAYS REPORT: British Property Federation – Fascinating study on tall buildings (in response to Boris quashing some of Ken's plans, I strongly suspect) in London: "The exercise was one of changing the distribution of employment, rather than total levels of employment. The economic benefit was equivalent to the annual output for each of those 80,000 workers increasing by £2,500 a year. A second scenario redistributing those 80,000 workers to less accessible parts of Central London produced a decline in output equivalent to £1,600 a year for every one of those 80,000 workers."

July 24th, 2008

These are my links for July 22nd through July 24th:

  • Target Finder : ENERGY STAR – Create building type specific targets based on US zipcode. Excellent resource, but be mindful the target is energy, not carbon.
  • New Buildings Institute – Getting to Fifty – There are no technical barriers, and few financial ones, to restrict the energy efficiency of most commercial construction from being at least 50 percent better than current code requirements. However, there is limited practical guidance for design teams
  • Advanced Buildings Home – Don't try this at home. Specification ensures energy reduction without modelling (US oriented – credits can be gained under LEED). In UK, of course, we now have SBEM. Modelling effectively mandatory…
  • Zero carbon houses cost up to £47,000 more to build – Building – As I flagged up yesterday, with a rather less sensationalist headline (slightly disappointed with Building on that one – not helpful in today's gloom and doom)
  • Ska rating: – Skansen Open Source fit-out assessment (BREEAM competitor). Still looks to be under development…
  • Is LEED still relevant? » Blog Archive » YoChicago – The pro's and con's of LEED are debated in the comments to this blog post.
  • RIBA CABE BSF – RIBA unsurprised at low quality of BSF design. RIBA "called on the government to let it road test the RIBA's alternative 'Smart PFI' model, which it claimed would 'would ensure design intelligence is deployed right from the start of any BSF programme'."
