Eco-friendly ways to keep your home cool in summer. Sunset Staff – July 11, 2021
To keep a house cool, itâs all about (1) keeping the sun out, or (2) keeping the air cool/conditioned. The key to this efficiency is having a solid thermal envelope for your home. In a typical residence, youâll see about 30 percent air leakage in the house duct system (this means hot air from the attic and from outdoors is leaking into the living spaces through electric plug sockets, recessed light fixtures, and the like). If your budget allows, have a local home-energy auditor do an infiltration test (or whole-house energy audit) to identify where leaks are located.
