Imagine Homes brings green building to suburban subdivisions
As former president of Medallion Homes, John Friesenhahn knew something about building energy efficient production homes in suburban San Antonio. When he founded Imagine Homes in 2006, he took that knowledge with him.
Today, Imagine Homes have many green building features seldom found even among custom builders in San Antonio.
Of course the toilets are low flow, but Imagine Home installs low flow dual flush units to save even more water. Water heaters are on demand units, but they also use a structured plumbing system to minimize the amount of cold water that has to be flushed out before the water becomes hot.
They have embraced the closed attic system and now insulate attics as well as walls with Demilec Agribalance foam, resulting in a semi-conditioned attic in which to place duct work. Low e windows improve efficiency while low VOC paint reduces air pollution.
Each bedroom has either a return air vent or a transfer grill to make for better flow of conditioned air. The HVAC system features programmable thermostats and maintains a slight positive pressure to keep outdoor pollutants outdoors and to push indoor pollutants out. Each house is blower door tested.
