A seatbelt buckle sitting in the sun will be heated by the sunlight, the hot air above the stove rises while the cold air from your refrigerator flows down when you open the door, and a fork or a spoon left in a hot dish can transfer that heat from the dish right up to your fingers. You probably have an intuitive understanding of how heat moves from place to place.

Attention to and maintenance of the building takes care of the latter, but the former is best addressed by a professional with experience in sealing building envelopes for your local climate.

This can be a problem in places where parts of the envelope are joined, such as the point where the wall meets the roof or where the edges of doors and windows meet the floor, but it can also appear through the surface of aging or damaged building materials.

A great deal of the loss of cool air during the summer is due to drafts and air leaks through cracks and other small passages. Adjusting AirflowĪir flow control includes not only attention to the air quality and ventilation of your home, but also to boost your energy efficiency, especially during seasons that require more heating and cooling. Especially during rainy winters, it is important to maintain elements of the building that direct rainwater away from the house or prevent it seeping through cracks, including gutters, spouts, caulk and weather-stripping. Water vapor control depends on managing the routes by which moisture enters a home: as vapor carried along with air movements, which can be addressed along with airflow and diffusion through permeable building materials, particularly foundations and walls that regularly encounter groundwater or standing rainwater. Damp building materials allow for the transfer of heat into the house much more quickly, but it also works the other way around the cool air inside an air-conditioned home draws humidity to condense onto walls, frames or insulating material. In addition to causing problems with mold and water damage, the passage of water and water vapor through to the interior of the envelope structure is a significant factor in the leakage of thermal energy. For specific solutions for your home, you can consult a Net-Zero Energy home building company in Scottsdale, but for your convenience, here are the three basic components of an energy-saving building envelope.

Net-Zero Energy efficient building envelopes are a huge factor in keeping energy costs down by limiting the amount of air and heat that is lost through leakage: a house that is properly and thoroughly sealed keeps the air and heat inside for longer, which means that your heating and cooling systems don’t need to work as hard to keep your home comfortable. It includes doors and windows, insulation and exterior walls, the foundation, and the roof. The building envelope is everything between the inside of your home and the world outside.
