ZEH Demonstration - Califon, New Jersey

 

Although it did not start out to be a zero energy home - the remodeling project performed by Bill Asdal (Asdal Builders) in conjunction with the NAHB Research Center and with support from the Department of Energy Building America Program, resulted in a newly remodeled home that will be a net-zero energy home. See how it was done and other project details by visiting the links below.

Before the remodel, two old farm houses sit side by side, looking very old and run-down.

After the remodel, the houses look brand new, with new siding, new trim, and solar panels on the roof.
