Sometimes the worst pollution can be experienced in Energy Efficient Buildings

Inadequate ventilation is by far the most serious cause of indoor air pollution, accounting for more than half of the problem, according to the National Institute of Occupational Safety and Health (NIOSH). Other lesser, but still significant, factors are aerosols, building products, cleaning and fragrance products and personal appearance products.

Air quality in a building is largely the result of an ongoing competition between the pollutants and the ventilation system. Other contributing factors include temperature, humidity, and microbial contamination.

Our efforts to make buildings more energy efficient and airtight have had an unexpected negative effect—increased air contamination resulting from decreased air exchange. Tightly caulked and sealed buildings without adequate ventilation systems trap pollutants inside the building. So we will shortly give you
