Links for February 22nd through February 23rd

February 26th, 2010

These are my links for February 22nd through February 23rd:

  • House 2.0: Dickon Robinson – "(Dickon Robinson) made some interesting observations about social housing, particularly so as he has been so intimately involved in it at Peabody. He recalled that the original council houses, built in the 20s and 30s, were only available to people who had jobs, and that they were regularly inspected by council officials to see that they were being properly cared for — these selection criteria were relaxed after WW2, when many families had to be rehoused. He then suggested that for some, social housing had become "deeply dis-empowering" because tenure was secure, rents were low and thus it "stopped you having to get up in the morning." He also spoke out against pepper-potting, the current practice of mixing affordable with private housing, the logic being to avoid building ghettos. He thought it hadn't been a great success and that, by and large, people were happier living with neighbours of similar social standing. Interesting thoughts, running counter to the prevailing mainstream"
  • two roads to solving the refurb crisis – part 2 « carbon limited – Great post from Casey – read both: "Here are my problems with using the SO to fund retrofit:
    1. It’s unfair – everyone pays, while only a small proportion of households get a retrofit in a given year
    2. It’s inappropriate – you’re asking the big energy companies to transform the energy market when their mission is the diametric opposite
    3. It’s a false market – government loves to let the market solve problems (quite right too!) but the supplier obligation isn’t a market, it’s just regulation. Large energy companies may be motivated to find the least cost option but not where the results would threaten their core business. This includes opening up the energy market to new players.
    PAYS on the other hand only affects those whose houses are refurbed and should keep bills steady rather than increase them. And done correctly, it could create a very large market of small and medium businesses, spawning competition and innovation."
  • Living with rats: Stop talking about the knowledge economy. Start building a wisdom economy. – As always, a thought provoking post from Julian Dobson: "The knowledge economy is competitive. The wisdom economy is collaborative. The knowledge economy assumes that if we can know that bit more than others, we will get what they have or keep them from getting what we have. It believes in dog eat dog. The wisdom economy says dogs do better when they hunt in packs. It sees knowledge as something to be shared and built collaboratively. It is highly suspicious of the intellectual property industry and the crowd of litigators and branding experts who hang on its coat-tails. Where the knowledge economy is amoral – your disadvantage is of no concern as long as I am succeeding – the wisdom economy accepts at a profound level that your disadvantage is my problem."
  • At last the Tories nail their planning colours to the mast – just in time for Bura@20 ! – The Regeneration Blog – Jackie Sadek comments on the Tory Green Planning paper: "Community engagement is really very hard to get right, particularly in areas of deprivation, and almost impossible in areas where there is wide disparity of household income. It just feels a bit naive; "Planning for Real" was always a little fanciful (almost hippie-like) and there now seems to be some sort of romantic notion that we can become like the people in "Passport to Pimlico".
    Frankly the Cameron claim that Open Source Planning "will mend our broken planning system" is really a very strong one. The claim that "it'll help to build stronger communities and help to mend our broken society too" is eye-wateringly ambitious indeed. The ideologue in me (still alive and kicking) would like to think it's worth giving it a go, but this policy is going to have to be implemented by people who really know what they are doing."
  • Argument Against Environmental Benefits of Locally-Grown Food – Not unbiased by any stretch, but some valid arguments: "The report explains that linear travel miles are not indicative of total energy use and therefore not necessarily a valid measure of the environmental impact of moving food over long distances. Instead of total miles traveled, the report states that the energy use per unit of food moved paints a more accurate picture of overall energy use…Shipping eggs across then entire U.S. by tractor-trailer to a grocery retailer is still the most fuel-efficient, eco-friendly option, said the report. This underscores the tremendous efficiency achieved through modern transportation systems and economies of scale. While the report did not examine all food products, it does conclude that “food should be grown where the agricultural resources and capacity are most suited to efficient food production,” rather than close to population centers."
  • Introduction : Future Venice – I found Rachel Armstrong via TED talks – this looks intriguing: "It is hoped that, since it is possible to design the metabolism of a protocell, a type of protocell might be engineered to capture carbon dioxide from a solution and turn it into its solid carbonate form to produce “pearls” of solid carbon dioxide. This system would form the basis for a new carbon-fixing building material. Early stage experiments to test this hypothesis are currently being conducted."

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."

Links for April 7th through April 9th

April 14th, 2009

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

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