Despite the immense popularity of outdoor living spaces here in Georgia, when people are at home they tend to spend the majority of their time

indoors. Research has shown that in general indoor air is much less healthy than outdoor air. According to the U. S. Environmental Protection Agency (EPA) website, “In the last several years, a growing body of scientific evidence has indicated that the air within homes and other buildings can be more seriously polluted than the outdoor air in even the largest and most industrialized cities. Other research indicates that people spend approximately 90 percent of their time indoors. Thus, for many people, the risks to health may be greater due to exposure to air pollution indoors than outdoors.”1

Poor indoor air quality can be caused by a huge variety of pollutants, including harmful chemicals, bacteria and mold. Certain building materials may emit some volatile organic compounds (VOCS) into the air. If the home is not adequately ventilated, these pollutants may build up inside. The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) recommends a ventilation rate of 0.35 ach (air changes per hour) for new homes.

It is very important to consider the quality of indoor air your homes will provide your clients once they move in. Undoubtedly, as professional builders you design your homes to include proper ventilation, moisture control and zero-VOC materials and finishes. Many new homes now feature mechanical systems, such as energy recovery ventilators (ERV) or heat recovery ventilators (HRV), that bring outdoor air into the home to refresh the indoor environment.
