Links for May 26th through May 27th

June 1st, 2010

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

  • Some Transition Thoughts on the Energy Bits of the Queen’s Speech » Transition Culture – I'm not a particular fan of the Transition Towns movement (something too insular and regressive about it to sit comfortably with my world view, each to their own and all that), but Rob writes some excellent pieces. This article is well worth a read – he knows his energy policies well and makes some good points about funding, FiT's and CCS.
  • Blogs and Comments – Comments – Dan Box – The Government has found a backhanded way to subsidise nuclear power – The Ecologist – Why Huhne's compromise on nuclear could be a good thing (IMO) although Box is obviously not happy: "The way it works is this: European companies currently pay for each tonne of carbon they emit by buying permits, the price of which is determined by the market itself. A floor price will most likely drive this price up…, making pollution more expensive. It will also encourage investors to put money into non-polluting companies by making the market in which they operate more predictable.<br />
    …Driving up the cost of producing polluting energy from coal- or gas-fired power plants, doesn’t just favour renewables. It also makes the costs of nuclear production far more competitive, even without subsidy."
  • Guest blog: Goodbye HIPs, Hello EPCs | National Energy Services – "From today, if you intend to sell your house you no longer need to have a HIP in place, but you do need an Energy Performance Certificate (EPC). To comply with the new law, you need to have instructed a Domestic Energy Assessor to prepare one, and either to have paid for it, or given a clear undertaking to pay, before marketing.<br />
    If you are selling through an agent, he or she must be satisfied that an EPC has been commissioned before starting to market your home. Both parties must make reasonable efforts to secure an EPC within 28 days, and all of the new duties carry fixed penalties where somebody fails to comply."
  • Footprint » Embodied carbon is the next hot topic – "Carbon profiling methodology is clearly explained and applied to a case study of Arup Associates’ Ropemaker Place, a 20-storey BREEAM Excellent office block in the City completed in May 2009. This research, commissioned by British Land’s Sarah Cary who was also on the panel, shows that embodies carbon makes up more than half of Ropemaker’s carbon emissions.<br />
    The next challenge is creating statutory incentives for reducing embodied carbon. Simon Cox of ProLogis described a recent project where planners were willing to reduce the renewables requirement in light of a sustainability strategy which had addressed embodied carbon. Guy Battle of dcarbon8 (and now Deloitte) remarked that the day will come Part L incorporates embodied carbon. Simon Sturgis noted that BREEAM awards less points for retaining a concrete frame than for putting bat boxes on a building."
  • Solar energy reduces electricity bills by a third – Modern Building Services – "The installation of solar photo-voltaic panels on affordable homes in Huddersfield has proved even more energy efficient than Kirklees Neighbourhood Housing and supplier Photon Energy expected.<br />
    Not only have the residents benefited from the production of solar electricity on site, but they have also become more economical in their use of electricity.<br />
    The panels have been installed on 30 all-electric bungalows and flats for older people at Fernside Estate in the Almondbury area of Huddersfield."
  • The climate-change greenhouse in a datacentre – "When you're building a datacentre, the biggest problem you've got is often getting rid of the heat generated by so many computers running in such a small area. Some data centres just pump it out into the outside world. Others use the excess energy to heat local homes. But TelecityGroup's newest datacentre, Condorcet – which opened in Paris earlier in the year, uses its heat to conduct research into climate change.<br />
    The building's exterior is comprised of a massive arboretum – a greenhouse, which is maintained at the climatic conditions expected to be prevailing in France in 2050. The French National Institute for Agricultural Research (INRA) operates a research centre there, growing plants from around the world to investigate which will be viable to grow when climate change's effects are starting to be felt in the country."

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.
