Links for July 23rd through July 27th

July 28th, 2010

These are my links for July 23rd through July 27th:

  • Worldchanging: Bright Green: Transition Towns or Bright Green Cities? – Read the whole article: “That sort of casual eagerness for the death of others is appalling. Worse, the strategy implicit in this vision of transitioning — that there can be local soft landings in the event of a global hard crash, that indeed the only proper scale at which to prepare for a soft landing is at the local level, and that perhaps collapse will solve some of our problems — is delusional.
    Collapse is not a tool for social change. …. Anyone who thinks an energy descent plan prepared by a community group future-proofs them against people like Charles Taylor has simply taken a vacation from reality.
    Local efforts can’t protect against the violence of a systemic breakdown. …To plan for the collapse of large-scale systems is to plan for widespread evil and suffering; ethical planning for the collapse is impossible: post-collapse idealism is oxymoronic.”
  • All power to the wind – it cuts your electricity bills – opinion – 26 July 2010 – New Scientist – “Insofar as there is a problem, it lies in handing control of industrial policy to marginally priced markets. Market-based decisions are not technology-neutral. They favour short-term profits, and that encourages the building of power stations with low capital costs and high marginal costs. That means gas-fired plants, which are tailored to make a profit whether the spot price is high or low.
    In fact, hardly any nuclear or coal-fired plants have been built in the past 15 years, only gas-fired plants, along with renewables installed thanks to support mechanisms such as feed-in tariffs.
    If those mechanisms had been ruled to be market-distorting subsidies and removed, leaving the market to make all the calls, we would see nothing but new gas plants built. This would leave us vulnerable, wondering where tomorrow’s natural gas, on which we would be utterly dependent, would come from – a scenario that has only been prevented because wind turbines receive support.”
  • Linking Green Buildings, Productivity and the Bottom Line | Buildings | GreenBiz.com – Interesting stats: “Indeed, the 2003 California report found average annual employee costs to be 10.25 times larger than the cost of space per employee. The author extrapolates these findings to calculate that a 1 percent productivity increase would therefore have a financial impact over time roughly equal to reducing property costs by 10 percent.”
  • More than Passive – Michelle Kaufmann Studio – “Although he is introduced to me as “one of the world’s great Passivhaus experts” (and having designed over 100 built Passivhaus homes, he has earned this title), Walter is quick to respond saying that is not the title he wants. He clarifies in our conversation as well as during his very compelling presentation the next day. While Walter commends the Passivhaus intentions, he says that it is about more than that. It is about good design. “Designing a Passivhaus is easy. But we need to make sure we are designing good Architecture as well.” It is much more than just calculations and scientific numbers. “Good architecture is not a scientific result.” His message resonates strongly, as this is a fear of green rating programs in general (whether it be LEED, or other), that some architects will simply follow the checklist and not innovate or design.”
  • A Bold New Model for Sustainable Cities – Robert G. Eccles and Amy C. Edmondson – HBS Faculty – Harvard Business Review – “Unlike the real estate developers doing places like Masdar in Abu Dhabi, New Songdo City outside Seoul, and Dongtan in Shanghai (basically “green” real estate plays with a “let’s build it and hope they come” approach), Living PlanIT’s model is to create an ecosystem of large and small company partners that will focus on creating products and services for sustainable urbanization. The people that the partners bring in to produce those products and services will be the anchor occupants of the model city. The hope is that this activity will then attract other businesses and inhabitants.”
  • Commercial Lighting Solutions: Login – With lighting set to be the bete noir of Part L 2010, this looks intriguing (but US based): “The Commercial Lighting Solutions provide actionable “how to” guidance on ways to improve your building interior lighting efficiency and reduce your energy consumption, without compromising quality design criteria. Strategies include the use of high performance commercially available products, daylighting, and lighting controls, all within the context of integrated designs supported by performance specifications.”
  • A Reporter at Large: The Island in the Wind : The New Yorker – Fascinating article on renewable energy in Denmark: “The biggest disappointment, though, had to do with consumption.
    “We made several programs for energy savings,” he told me. “But people are acting—what do you call it?—irresponsibly. They behave like monkeys.” For example, families that insulated their homes better also tended to heat more rooms, “so we ended up with zero.” Essentially, he said, energy use on the island has remained constant for the past decade.”
  • Building4Change : Are airtight homes good or bad for occupant health? – “There is already strong evidence that energy efficient homes have a positive impact on occupants’ physical and mental wellbeing. Basic improvements in indoor temperature levels in winter and reduction in fuel poverty can have a significant impact. But there is a shortage of evidence to inform decision-making in this area and it is vital that risks to public health are not increased
    There are a number of areas where more knowledge is needed. Although 0.5 air changes per hour is the accepted norm, we lack a definitive assessment of a safe minimum level of ventilation. There is no comprehensive study on the part that home ventilation plays in ensuring health. We have insufficient knowledge of the actual ventilation rates being achieved in UK homes, impacts of ventilation system design, installation and operation, and impacts of occupant behaviour.”
  • How to test your decision-making instincts – McKinsey Quarterly – Strategy – Strategic Thinking – This means that to protect decisions against bias, we first need to know when we can trust our gut feelings, confident that they are drawing on appropriate experiences and emotions. There are four tests.
    1. The familiarity test: Have we frequently experienced identical or similar situations?
    2. The feedback test: Did we get reliable feedback in past situations?
    3. The measured-emotions test: Are the emotions we have experienced in similar or related situations measured?
    4. The independence test: Are we likely to be influenced by any inappropriate personal interests or attachments?
  • Enough With Jane Jacobs Already | By Andrew Manshel – WSJ.com – An odd article, but it reminded me of the existence of Whyte’s video “The Social Life of Small Urban Spaces”, which can be found online, worth hunting out: “More attention ought to be paid to the finely grained thinking of William H. Whyte and less to Jacobs’s overblown pronouncements and unprovable theories. Whyte was a close observer of people’s behavior in public spaces and emphasized the importance of the many subtle design features that make people comfortable in parks, plazas and public buildings. Following Whyte, designers, planners and community members need to pay more attention to proven, good ideas, to established data and to the fine points of landscapes and buildings.”
  • They don’t build them like they used to: Steve Mouzon’s Original Green | Kaid Benfield’s Blog | Switchboard, from NRDC – ‘Original green’ means common-sense things like building with high ceilings, cross-ventilation and shading in warm climates, and building with steep roofs and southern exposure in cool ones. It means using original forms of transportation, such as walking and bicycling, whenever possible, and designing and inhabiting communities that facilitate such self-propulsion. It means growing food nearby, and ‘living local’ as much as possible. It means accepting a wider ‘comfort range’ of temperature; our ancestors, Steve points out, were adaptable and reasonably comfortable within a range of 30 degrees or so Fahrenheit; today people fight over two degrees’ difference in ‘thermostat wars.’ Original green places and buildings have intinsically smaller environmental footprints than conventional buildings and places, especially when lifecycle effects are included, and in many cases even if the conventional ones have the benefit of green technology.
  • Theses on Sustainability | Orion Magazine – Worth reading the entire artcile: “THE TERM HAS BECOME so widely used that it is in danger of meaning nothing. It has been applied to all manner of activities in an effort to give those activities the gloss of moral imperative, the cachet of environmental enlightenment.”
  • Dynamic Thermal Properties Calculator – Free excel tool, includes decrement, admittance and kappa values: “The motivation for producing this tool is a growing need among architects and engineers for more information about the thermal properties of construction elements other than just their U-value. This is needed to help optimise the passive performance of buildings and ensure a high level of inherent energy efficiency. Going forward, it is likely that far more attention will be paid to getting this right given the forthcoming changes to Part L and SAP. Another driver is the issue of climate change adaptation, which is starting to result in greater scrutiny construction materials and their thermal properties.”
  • Climate change weather file generator – CCWeatherGen – Adaptation is flavour of the month: “The CCWeatherGen tool allows you to generate TMY2 or EPW climate change weather files with a few mouse clicks. You can produce ‘morphed’ climate change as well as ‘unmorphed’ present day TMY2 and EPW files from the original CIBSE/Met Office TRY/DSY format files. The CCWeatherGen tool is made available free of charge. However, it is solely distributed WITHOUT the required baseline weather files and/or climate change scenario data!”
  • 2degrees : Discussion Topic – “BSI has announced the launch of its new Kitemark® scheme for Energy Reduction Verification (ERV) which will independently verify and certify those organisations that achieve a reduction in carbon emissions through lower energy use. The Environment Agency has approved the scheme as one of the Early Action Metrics that contribute to the CRC Energy Efficiency Scheme, the UK’s mandatory climate change and energy saving scheme.”

Links for April 7th through April 8th

April 9th, 2010

These are my links for April 7th through April 8th:

  • Bleak and tortured: Kapoor’s Orbit is hardly an Olympic ideal | Building Blog – “the fact that Kapoor’s works seems to have garnered criticism from critics and the public alike renders it, in this regard at least, unique.
    what does it say?
    And this perhaps is Orbit’s biggest flaw and the reason why it has attracted such negative publicity. To the mayor of London and the London 2012 organising committee, who have been gushing profusely about the sculpture since it was unveiled, it clearly provides a big, pop-art symbol of the games that will doubtless look good on TV and divert attention away from the fact the London Olympic Park lacks much of the architectural ‘wow’ factor so clearly evident in Beijing.”
  • Self Reliance Myth – Debunking some myths (read the whole post): “I hear people say they are growing 30%, 50%, even 70% of their own food. What they usually mean is that they are growing fruits and vegetables that make up some percentage of the total cost or weight—but not calories—of their food. Vegetables are high in wet weight, but low in calories. If you are growing 100% of your own vegetables, they provide about 15-20% of your daily calories, unless you are living mostly on potatoes or other starchy veggies. Most daily calories come from grains, meat, or dairy products. So if you’re not raising large-scale grains or animals, it’s unlikely that you are growing more than one-quarter of your own food, measured honestly by nutritional content. In that case, it’s not accurate to claim you are “70% food self sufficient.” …. Now we begin to see how difficult, and even undesirable, self sufficiency is. You won’t have time for much else if you are truly food self sufficient, even in a permaculture system.”
  • IES » » In Practice: linking Revit to IES – “it is important to note that gbXML is not perfect and limitations transferring information between BIM and energy simulation software still exist. A key issue to understand, when looking to cycle through design options in a timely manner, is that there are some fundamental differences between an energy model for analysis and an architectural model used to generate construction documents. For example, many BIM elements do not support information exchange identifying the thermal performance characteristics that are needed to run energy analysis. …
    At early stages, if you take the perspective of the energy modeler they want to include the minimum amount of information to answer the question at hand, to reduce the variables and the analysis time. If you take the perspective of the architect, the visual character of the overall model is important to convey the design intent, as well as the details to express the layering of the idea(s).”
  • marklynas.org | Why no party can afford to be anti-nuclear – “By attempting to be populist but appearing merely outdated, the Lib Dems have produced an energy policy that is by far the least realistic of the plans by the three major parties. On 19 March, the Conservatives launched a sensible plan for a carbon tax on electricity generation to encourage investment in both nuclear and renewable power. After years of dithering, Labour is now on track with its large-scale offshore wind programme, nuclear new-build and major grid upscaling.
    The Lib Dems are left with wishful thinking. The writer David MacKay summarised their approach in his book Sustainable Energy: Without the Hot Air as “Plan L”, which would leave a zero-carbon Britain dependent on imports for two-thirds of its electricity, and on coal for much of the rest. (This is “clean coal”—a technology yet to be invented on the required scale.)”
  • House 2.0: Part G and the Water Calculator – Comment from Nick Grant on Mark’s Part G post: “The calculator approach is inherently flawed (on many levels) but cannot easily be dropped as it was voted on by ‘Stakeholders’ and became policy. There is a critique on my website which led to a review for CLG. Unfortunately the report of the review has not been published as I would rather reference that.
    Many of us find it really draining to have to put so much effort into debunking seriously flawed policies as you regularly flag up on your blog. We would rather get on with designing more sustainable buildings (and renovations) but have to spend huge amounts of time and effort (usually unpaid) arguing against supposedly green policies that are making things worse.”
  • Awash in Awareness: Knowing a Product’s “Water Footprint” May Help Consumers Conserve H2O: Scientific American – “Concerns over greenhouse gas emissions have vaulted the term “carbon footprint” into mainstream vernacular. Now, by promoting the concept of a “water footprint” with the goal of including it on product labels, researchers are hoping to draw similar attention to how drastically we’re draining our most precious resource. As the use of a footprint to gauge water use gains popularity, however, researchers are struggling to reach a consensus on how best to measure that footprint so the public understands its full impact.”
  • Urban Resilience § SEEDMAGAZINE.COM – Fascinating article on resilience: “From a systems standpoint, what cities are doing is creating a network—which in itself could strengthen resilience. Knowledge generated in one place could be used in another, and experiences and best practices could be shared. But this power shift raises an interesting governance question, as every organization in place today when it comes to global governance—the CBD, the United Nations, the Law of the Sea—is based on the nation state. Now on the sidelines, a very powerful network of cities is growing, sharing information technology, and driving an ambitious sustainability agenda.”

Links for January 23rd through January 26th

January 29th, 2010

These are my links for January 23rd through January 26th:

  • Not the last straw: Homes made from straw bales make a comeback | MNN – Mother Nature Network – Volunteer labour makes costing straw bale difficult: "Though the materials used for straw bale buildings – straw & plaster – are typically inexpensive, the special knowledge required to design & build these structures usually means that labor costs can be anywhere between 10 percent and 20 percent higher than for traditional buildings, though some of that cost is made back through energy efficiency.
    “The construction of these buildings takes a person who’s done tons of training to really understand exactly how to get the material to behave,” says Moore. “It just ends up costing the consumer too much money for the benefit it produces.”
    In addition, straw bales can create extra hassle in terms of coordinating their delivery from local farmers, having a big enough job site to store all the bales and keeping them dry during construction.
    One way that people help keep labor costs down is to throw “bale raising” parties where friends & family members help stack bales and plaster walls."
  • Forget Sustainability, It’ s Time to Talk Resilience – "There's a new concept infiltrating the climate change conversation, and it has the potential to change the conversation altogether. It’s time to give sustainability a rest and start talking about resilience, Rob Hopkins writes in Resurgence.
    “The term ‘resilience’ is appearing more frequently in discussions about environmental concerns, and it has a strong claim to actually being a more successful concept than that of sustainability. Sustainability and its oxymoronic offspring sustainable development are commonly held to be a sufficient response to the scale of the climate challenge we face: to reduce the inputs at one end of the globalised economic growth model (energy, resources, and so on) while reducing the outputs at the other end (pollution, carbon emissions, etc.). However, responses to climate change that do not also address the imminent, or quite possibly already passed, peak in world oil production do not adequately address the nature of the challenge we face.”"
  • House 2.0: The Denby Dale Passive House – "Because of all this, the house down the end of Geoff and Kate’s garden has assumed a significance they cannot have dreamt of when they first contacted Bill Butcher. It’s not just a low energy house, it’s a Passive House. And it’s not just a Passive house, it’s an assault craft landing on the beach that is the Code for Sustainable Homes. By 2016, when in theory the Code should kick in fully and all new homes should be “zero carbon”, you would not be allowed to build this house. For a start, it is going to have a gas boiler — not permitted under Code Level 6. And it will have nothing in the way of home-generated electricity (although the Feed-In-Tariff coming on stream later this year may cause Geoff and Kate to reconsider)."
  • Archinect : Views : Victory Gardens, or the Impact of the Financial Crisis on Architecture – Gloomy, but worth reading the whole article: "The hard part is going to be for architects to understand just how this is healthy for the profession. First, architects have hardly raised their productivity since the integration of digital design tools into their work. Sure, designs have gotten much more complex, but more isn’t always more. Many firms have wound up wasting labor on gimmicky designs produced by an army of interns. Now those firms are going to finally begin using technology the way it was meant to be. Watch as fifty-person firms shrink to five or ten core employees. Instead of talking about the cool things that digital technology can make, architects are going to talk about how fast and efficient digital technology makes them.
    That will be a huge paradigm-shift and will lead to more interesting work along the way."
  • Sustainability: Carbon reduction – Building – Everything you need to know about CRC: "So is the financial liability placed on organisations by the CRC significant enough to demonstrate a convincing business case for improving energy performance in existing buildings? Not quite. However, the business case becomes more compelling when energy savings are taken into account as shown in the table below.
    Early investment in more energy efficient systems can reap significant savings in terms of reduced energy costs. The example shows the initial investment paid back in less than four years. If early action is difficult due to the current economic climate, then appropriate investment in time for the capped phase (2013) will also significantly reduce CRC liability and generate substantial energy savings.
