I love roof overhangs on so many levels. On the symbolic level they convey a sense of protection and security as they shield us from the elements. They’re welcoming, like open arms saying, “…hello, here is the entry, come inside”.
On a purely functional level they are great climate modifiers, keeping the walls dry at critical joints, and are particularly effective at shading summer sun.
As a crusty waterproofing consultant once told me “I would be out of business if every building had generous roof overhangs; a poorly designed or constructed detail will not leak a bit if it doesn’t get wet”. At Stillwater we have embraced generous roof overhangs and always try and employ them, particularly over windows.
It seems to me a tax system that encouraged people to work hard by mainly lowering income tax and encouraged people to use less fossil fuel by taxing carbon, would be a better way to go. To achieve a greater independence from fossil fuels it’s most effective to have both carrots and sticks. The good thing about a carbon tax is it would be effective, transparent, and not nearly as susceptible to manipulation and gaming as can be the case with incentives. If such a tax caused the average new home size to drop by 300sf, would that be such a bad thing? Bjorn Lomborg, the controversial Danish economist, has pushed his way back into the global warming debate with a book that proposes “smart solutions” to climate change. Those promised solutions rely heavily on R&D aimed at making clean energy cheap, rather than attempts to shut down dirty energy sources. Lomborg says his views haven’t changed, but more people are willing to listen to him because international negotiations on limiting greenhouse emissions have accomplished so little. Dan Charles
If you haven’t already read about the BEDZED project on the outskirts of London, it’s worth a look. A trendsetter at the time, its still is one of the go-to examples of zero energy sustainable housing of significant scale. Eye catching as it is, the front facades may well be too uniform and anonymous for American urbanites not accustomed to the row house so ubiquitous in the “suburbs” of the United Kingdom. Kate Andrews of Inhabitat explores further:
BEDZED: Beddington Zero Energy Development in London
“The Beddington Zero Energy Development (BEDZED) may not be new news, but is a fabulous example of innovative, zero-energy, sustainable housing on a multi-unit scale. The residential and workspace development in the London borough of Sutton is a carbon-neutral community with plentiful green spaces, recycling facilities, water saving features, and a legally binding green transport plan. It’s the whole kit-and-caboodle of sustainable living, and has been a flourishing green community since its conception in 2002.”
