Overall, heat is mainly lost through the roof and walls, while cold air enters the house from lower parts. As a result, energy is wasted due to air movement.
In the upper areas, warm air escapes through the attic hatch and recessed lights. Heat is also lost through bathroom and kitchen fan vents. In addition, air leaks out through small gaps around electrical outlets and the plumbing stack vent.
In contrast, cold air enters the house through the crawl space and around the outdoor faucet. As warm air escapes from the house, cold air is drawn inside from these lower areas. Therefore, energy is wasted because of poor insulation and continuous air leakage.
