Indoor Air Quality
U.S. EPA studies have shown many airborne pollutants are 25 to 100 times more concentrated in indoor air than they are in outdoor air. Combine that with the fact that most people spend 90% of their time indoors and you might appreciate how important indoor air quality is. Toxic substances such as radon, formaldehyde, carbon monoxide, pesticides, molds, and household chemicals permeate the interiors of most homes.
Sustainably Built will help you minimize the presence of these pollutants through better design, proper ventilation, and the elimination of products that contain these toxins. Mold can be prevented through proper window and roof details, good penetration coverings, proper drainage planes, and the right vapor profile. Radon mitigation should always be practiced in new home construction, and old homes should be tested for excessive levels. Formaldehyde is an uncessessary but common chemical in building materials. By specifying formaldehyde-free insulation, wood products, adhesives, carpets, and upholsteries, formaldehyde can be eliminated from the building.
With the abundance and affordability of sealed-combustion heating equipment, combustion gases like carbon monoxide need not ever enter the building envelope. Proper sealing of the connection between the garage and living spaces help keep engine emissions, gas and oil vapors, pesticides, and other household chemicals out of the living space. Finally, mechanical ventilation helps ensure that if any of these substances enter the building, they will quickly be flushed out.
