Whole House Fan

  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...

  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. But there’s actually an easier place to start: using an energy-saving whole-house fan.These fans blend advanced cooling technology and whisper-quiet operation, making them effective at circulating fresh air throughout your home without needing too much power! Powerful ventilation at a lower cost Besides cooling your home, a whole-house energy-saving fan lets you ease into a more sustainable lifestyle. QuietCool fans  are certified by the  California Energy Commission , meeting strict standards for efficiency and environmental responsibility. With high-performance motors and insulated ducting, they improve airflow while reducing your home’s energy consumption.   Compared to air conditioning units, whole-house fans that are energy efficient use only a fraction of the power, soyou’ll likely n...
