Exhibit 1, Item 7) Provisions of the DOE Zero Energy Ready Home PV-Ready Checklist (Revision 07) are Completed.

DOE Zero Energy Ready Home National Program Requirements Mandatory Requirement 7 (Renewable Ready) shall be met by any home certified under the DOE Zero Energy Ready Home program, only where all of the following conditions are met:

1. Location, based on zip code has at least 5 kWh/m2/day average daily solar radiation based on annual solar insolation using PVWatts online tool, AND;
2. Location does not have significant natural shading (e.g., trees, tall buildings on the south-facing roof, AND;
3. Home as designed has adequate free roof area within +/-45° of true south as noted in the table below. 

DOE recommends but does not require solar thermal water systems. See the DOE Zero Energy Ready Home Solar Hot Water-Ready Checklist (Encouraged).
