Constructing leaky buildings isn’t the answer.
It’s true that well constructed, energy-efficient houses save money and energy. And with suitable mechanized ventilation, they can have better indoor air quality than a leaky building. The principal factor behind this is control.
In a drafty household, outdoor air enters the home intermittently via cracks, unsealed joints and penetrations, depending mostly on the climate. Often there will be extra leakage, leading to a drafty, unpleasant home. In other buildings there won’t be enough, resulting in a stuffy home. Mechanical air flow in a properly-insulated, well-sealed home; will exhaust pollution and bring in outdoor air in a controlled, premeditated process. This key fact makes a dwelling both comfortable and energy efficient.
Utilize energy efficient design. Developing tight, suitably-insulated homes reduces heating and cooling costs. Household air quality and energy efficiency walk hand in hand.
Controlling humidity in a home can help get rid of mold, mildew, and various biological growths that have been linked to a number of ill health effects. Building an energy efficient residence with good air sealing and the use of barriers and diffusers to control vapor properly are crucial. The whole building envelope, from the foundation to the roof, needs to be engineered to not just stop moisture entry, but also to permit any moisture which does enter a means to escape. Sufficient ventilation should help make sure that moisture stays within appropriate levels.
Removing or managing individual sources of pollution are essential steps in providing good indoor air quality. If you utilize the appropriate materials, isolate those which are known to cause problems, and supply sufficient ventilation, the levels of indoor pollution in your home may be greatly reduced. Suitable ventilation purges or reduces the concentration of stale air in the home, and imports fresh air from outside.
Along with other methods, selecting, installing, and integrating your home’s combustion equipment is an important component to building a house with safe indoor air quality. Because of the potential for combustion appliances to generate pollutants that can harm your health, they must be properly set up, operated and maintained correctly. Poorly or incorrectly vented appliances can greatly increase moisture in the air, introducing both biological growth, and damage to the home. The good thing is, contractors can take steps to lower the risks for combustion equipment.
The way in which a home is handled, maintained, and lived in is an important factor affecting indoor air quality. Preparing for this maintenance during your home’s construction process and grasping the most important concepts will promote good indoor air quality, and even reduce potential problems with the structure of your home for years to come.
