Home attic fans are supposed to cut cooling costs and keep temperatures down — but most people install a quiet attic fanand just hope for the best, never bothering to check if it’s working. The Florida Solar Energy Center (FSEC) wanted actual proof.They ran a field study on a single-family home in Cocoa, Florida, where summer attic temperatures can soar past 130°F. The house already had solid insulation and a radiant barrier, so they weren’t expecting dramatic gains. But still, after installing two PV-powered attic exhaust fans, the team saw a measurable drop in peak attic heat and noticeable changes in HVAC energy use. How they tracked the results FSEC logged temperature and power data around the clock. They wired the home with sensors and recorded data every 15 minutes to build a full thermal and electrical profile before and after the fans went in. In the attic, they installed Type-T thermocouples to monitor air temperature. Paired with indoor and outdoor readi...
From Power-Hungry to Power-Smart: Why Upgrading to Energy-Efficient Fans Is Essential for Lower Bills and Greener Living in 2025
If you’re looking for a way to reduce your energy use without giving up comfort, you might be considering putting money into better insulation or maybe a new HVAC system.
