These Homeowners Pay Almost Nothing for Heating and Cooling

EarthTalk is a Q&A column from E/The Environmental Magazine
Dear EarthTalk: I recently saw a reference to “Enertia houses” that require little in the way of external sources for heating or cooling. Do you have any information on this housing design? — Alan Marshfield, via e-mail
Enertia is a brand name for homes designed and sold in kits by North Carolina-based Enertia Building Systems (EBS). The idea essentially marries the concepts of geothermal and passive solar heating/cooling into what amounts to a highly energy efficient hybrid system. Architectural inventor Michael Sykes coined the term “Enertia” in the 1980s to describe the innovative homes he was designing that would store solar and geothermal energy and make use of it for most if not all heating and cooling needs.
