The conventional American home lets heat in from under doors and around window sashes, and right through under-insulated walls.
While wind turbines and solar panels are impressive green technologies, the way to really slash one's bills and environmental impact is to live in a hyper-efficient house, and it doesn't get more hyper than the "passive houses" now being developed. These are essentially maximum-security prisons for thermal energy, with thick insulation that leaves no unprotected studs to conduct heat to the outdoors, triple-pane windows and an overall approach to air-tightness that lunar colonies could aspire to.
In Europe, as many as 6,000 homes have been passive-house-certified in the past decade, with thousands more approaching, though not quite meeting, the rigorous requirements. According to energy-efficiency consultants, a passive house in the northeastern United States could consume 90 percent less heat than equivalent sized current homes.
Passive houses have been shown to be among the most reliable and cost-effective approaches to efficiency. In Germany, off-the-shelf windows, gaskets and other passive-house-certified products have brought construction costs to within 5 percent of those for conventional homes. In the United States, that price premium can be 11 percent or more.
With any new construction you want to make sure that insulation, air-infiltration and weather-sealing are the best they can be. Even if the extra attention to detail adds a few thousands of dollars to the construction cost it is quickly recovered with hundreds of dollars saved every month.
