Maverick NYC mechanical systems designer Henry Gifford has long been a critic of LEED, arguing that it encourages the wrong things, and doesn't go far enough to ensure that certified buildings really save energy or provide good air quality. I have great respect for Gifford and the work he does to design and commission low-energy buildings with great ventilation on very tight budgets. Unlike too many practicing engineers, he knows exactly how much energy his buildings are using.
I was down in Orlando last week — land of asphalt, ChemLawns, and Mickey Mouse. As is typical in that part of the world, it was too hot outside and too cold inside. In one of the mammoth Disney hotels, I was participating for two days in the Tenth Anniversary Annual Meeting of an organization called FLASH. FLASH is the Federal Alliance for Safe Homes — it used to be the Florida Alliance for Safe Homes, which explains the "L."
Rigid boardstock insulation.
In this final installment about insulation we'll take a look at the family of rigid boardstock materials. Unlike fiberous or spray-foam insulation that is installed in wall or ceiling cavities between the studs, rafters, or joists, boardstock insulation is applied either on the interior or exterior surface, spanning across the framing.
"Water shortages are expected to become more and more common in the coming decades. A 2003 report by the U.S. General Accounting Office reported that 36 states are likely to experience water shortages by 2013."
A wind turbine ad on the New York Times homepage! Sure, Web ads are relatively cheap, but it still looks like a sign that alternative energy is hitting the big time.
As a key component in polycarbonate plastics such as those used for reusable water bottles, baby bottles, canned-food liners, and some building materials, bisphenol-A (BPA) has become the new chemical to fear.
This press release just came through; sounds like it will be a pretty great resource. It's not up yet though — check it out in a few days.
The U.S. Green Building Council has announced that LEED 2009 is open for a second public comment period, from now until September 2, 2008.
Although not as green as cellulose, batt insulation makes sense under certain conditions.
Last week's column addressed cellulose insulation, which is the greenest and one of the most effective insulation materials available. But it isn't always practical or affordable to install cellulose. To insulate walls with cellulose, it's usually necessary to hire an insulation contractor, and if the job is very small--bumping out and reinsulating one wall of your home, for example--the cost may be prohibitive for that small improvement. This is where batt insulation makes sense.
Here's a fun exercise that a group of architects, designers, and others completed today as part of the Designing for a Living World symposium that I'm attending, hosted by Interface at Shelburne Farms in Vermont. It's a little thing I call... "Headlines from the Future."
Here's the deal. Take these ten topics:
Oceans
Agriculture
Energy
Poverty
