Ventilation Solutions

Energy efficient windows and doors, thicker insulation and air tight vapor barriers have made buildings more efficient, saving both energy and money. While this has made many buildings more efficient, it has also made it nearly impossible for these buildings to “breathe” to expel the stale polluted indoor air and exchange it for cleaner, fresher outdoor air.

If too little outdoor air enters a building, pollutants can accumulate to levels that can pose health and comfort problems. Unless they are built with special mechanical means of ventilation, buildings that are designed and constructed to minimize the amount of outdoor air that can “leak” into and out of the building may have higher pollutant levels than other buildings. However, because some weather conditions can drastically reduce the amount of outdoor air that enters a building, pollutants can build up even in buildings that are normally considered “leaky”.
