EcoHat adorns energy-efficient tract homes
Wednesday, March 12th, 2008
Tract homes are turning eco-chic, at least in a small town outside of London. British architecture firm Rogers Stirk Harbour & Partners has designed a 145-unit housing development in England that could be a future model for efficient housing around the world. The two-story homes, which are between 700 and 1,400 square feet, feature a modern twist on the English chimney: the Ecohat.
Sounds like something a hippie would put on in winter, but the EcoHat is an aluminum structure (painted bright red) that contains powerful solar panels and an airflow system to optimize energy consumption inside the home. Sitting on the spine of the house like a chimney and angled toward the sun, the Ecohat filters fresh air coming into the building for natural air-conditioning and reuses hot air circulating through the stack to power a hot water system.

SAN FRANCISCO–Ten years ago, a designer of a top-selling toothbrush might beam with pride over his or her creation. But seeing that indestructible saber of plastic washed up on a beach shore–battered but relatively unchanged–might cause the same designer some pause in today’s eco-conscious climate.
The World Wildlife Fund UK, a nonprofit conservation group, uncovered in a recent report that the world’s top 10 makers of luxury brands–the likes of Bulgari, Tiffany, LVMH–have less-than-stellar records on environmental and sustainable business practices. (Story
Metropolitan cities are setting the example this year on decorating with eco-Christmas lights. San Francisco this weekend, followed by Paris on Monday, lit massive holiday trees with mini light-emitting diode bulbs, which burn brighter than typical bulbs and emit no heat. The LEDs consume about 90 percent less electricity than typical lights and can last as many as 20 holiday seasons.
