Indoor Air Quality
Can be affected by many of the products used in the construction of your home as well as products used for cleaning and maintenance. Careful product selection during construction can significantly reduce dangerous off gassing by materials with a high voc content.
Proper ventilation can be a huge factor in a homes performance. Poor ventilation can lead to moisture build up or condensation which can cause mold and other unwanted growths. This can have adverse effects that can cause respiratory ailments and other illnesses.
Inadequate ventilation can increase indoor pollutant levels by not bringing in enough outdoor air to dilute emissions from indoor sources and by not carrying indoor air pollutants out of the home. High temperature and humidity levels can also increase concentrations of some pollutants.
Lack of proper ventilation can also lead to build up of toxic gases caused by combustion sources like wood burning fire places, gas water heaters, and HVAC units.
Careful planning is needed when trying to balance energy efficiency and indoor air quality. Good bathroom exhaust fans should be used whenever possible even though they are not required by code if window ventilation exists. Most people don’t prefer to open windows in cold winter months or when air conditioners are being used which can inhibit proper ventilation.
