Ashland Net Zero
This Premier SIP-built single-family home is sited on an east/west axis to allow passive solar gain, as well as align the roof for both solar thermal and PV Systems. The client wanted to build the shell especially energy efficient so they could go Net Zero.
SIPs were a great fit for this job not only for the energy efficiency but because it was a tight infill lot. The structure was installed very quickly with the walls going up in just six hours...including lunch. It took just six hours more to install the roof a day later.
Innovative Design Elements:
The floor is a full floating R-20 insulated slab. The walls are 6" SIPs with 2x4 nonbearing interior walls to break thermal bridging and allow more insulation. The total wall R-Value is R-45.
