Environmental Quality
Good air quality is an important environmental consideration. The air quality inside the home can aggravate and even cause respiratory problems. To boost air quality high performance home heating, ventilating and cooling systems control indoor moisture and reduce particulates and toxins. Using natural ventilation is a great way to improve air quality. Natural ventilation uses the dynamics of wind flow and pressure to move air through home spaces.
