QC Manufacturing, Inc. has for years been selling the brand QuietCool with the claim that our systems help save homeowners up to 50-90% OFF their A/C-related electricity costs. And while we knew this to be true, and our customers knew this to be true, it has taken years for the power brokers in Sacramento, and elsewhere, to believe in whole house ventilation technology.
California Energy Commission
That changed on May 31, 2012 with the announcement by the California Energy Commission, “Energy Commission Approves More Efficient Buildings for California’s Future.” The Standards, which took effect on July 1st, 2014, “offer builders better … ventilation systems and other features that reduce energy consumption in homes and businesses… some improved measures in the Standards include… whole house fans to cool homes and attics with evening air reducing the need for air conditioning load.” Greater detail is provided in the State of California Energy Commission’s, 2013 Building Energy Efficiency Standards Discussion Paperwhich outlines the state’s general strategy to lead California to “Zero Net Energy” by 2020 for newly constructed homes, and 2030 for newly constructed commercial buildings. To be sure, the new Title 24 measures, that took effect July 1st, 2014, are wide ranging initiatives designed to reduce humans’ carbon footprint. In the Energy Commission’s exhaustive 2013 Building Energy Efficiency Standards Administrative Regulations, at page 226, the new regulatory standards for whole house fans are more clearly outlined. For starters, Title 24 will require that all new construction homes in 7 of California’s 16 climate zones will require the installation of a whole house fan.
Moreover, the standard for system air flow matches the recommended system configuration of 2 CFM/ft2 that QuietCool has been promoting for years. What is new, however, is that the attic venting requirement will require 1 square foot of attic venting for every 375 CFM blown by the system. This will require that new home builders increase the amount of attic venting to meet the new standard. Dealers and contractors are interested to know where the new Title 24 rules will apply since the new regulations do not apply statewide. The seven climate zones to which the new law applies are zone 8 through 14 on this climate zone map. Finally, the law states that where “whole house fans are required, only those whole house fans that are listed in the (California Energy Commission) Appliance Efficiency Directory may be installed.” And, of course, every QuietCool dealer and customer knows that QuietCool systems are the most energy efficient whole house fans on the market today, as listed on this very same Directory!
