As buildings become more airtight and energy efficient, actively managing indoor air quality becomes more important. Not only are some air pollutants highly dangerous, but many—like radon and carbon monoxide—are undetectable by human senses. And with 90% of our time typically spent indoors, slight elevations of VOCs can amount to chronic exposures.
Here you’ll learn what pollutants to be wary of and ways to promote clean, fresh air, including:
finding the right level of ventilation
specifying products that won’t emit problematic chemicals
controlling pressure differentials to avoid unintentional introduction of polluted air
The BuildingGreen Guide to Insulation provides detailed guidance on insulation products and practices, including cost comparisons and detailed recommendations on what insulation to use, and what to avoid.
Build Equinox and Minotair Ventilation Inc. (MVI) have updated their heat-pump-based energy recovery ventilation systems, providing better control of humidity, heating, and cooling in a smaller footprint.
The number of environmental product standards and certifications is growing rapidly, putting numerous different "green" logos on products. This article reviews the key programs and evaluates their rigor, and offers guidance in using them to accomplish project goals.
