Three Ways to Build a More Comfortable, Energy-Efficient Home

For homeowners planning a custom build, Reid also suggests discussing zoning. Someone who prefers a colder bedroom at night may benefit from controlling that area separately instead of cooling the entire house to the same temperature.

2. Pay Attention to Air Leaks

Insulation is often the first thing people associate with energy efficiency. Reid encourages homeowners to consider the gaps that allow air to move through the building envelope, too.

“Sealing up the gaps and cracks in a home make a huge difference,” Reid said.

He points to areas around outlets, sill plates, and openings between living spaces and the attic. Even a heavily insulated wall cannot fully compensate for gaps that let outside air enter.

In his work, spray foam is one method used to address those leaks. Sealing penetrations into the attic, including those around recessed lighting, is another area he highlights. The goal is to help the home maintain its indoor temperature more effectively.

3. Plan for Fresh Air and Humidity Control

Ventilation is another part of a comfortable home. Reid highlights air exchangers, which introduce fresh air and can help manage indoor humidity during winter.

That matters when excess moisture contributes to condensation on windows. He encourages homeowners to consider how their ventilation system supports the indoor environment alongside heating, cooling, and air sealing.

For Reid, the larger point is that efficiency improvements should be evaluated by how they affect daily living as well as energy use.

When you create a more energy-efficient home, you’re creating a more comfortable home.
