"Housing consumes 40% of our nation's energy use,1 making it a prime target for energy-efficiency measures. Steps such as adding insulation, installing high-efficiency HVAC (heating, ventilation, and air-conditioning) systems, and tuning furnaces rank high as simple ways to lower utility bills and improve comfort and indoor air quality. But an energy-efficiency label attached to a product is meaningless if that product is installed incorrectly, and when it comes to green building techniques, the devil is in the details. The complexities of high-tech equipment and the subtle and usually invisible movement of air and moisture in homes mean even experienced and well-intentioned contractors do not get things right in every instance. This can result in health problems for occupants and installers alike."
