Frederick Net Zero Home
The home is designed to maximize the sun coming into the building all winter providing free solar heat and great daylight all winter. The heating system never comes on during the day in the winter. To keep the heat in, the home is highly insulated with 12” thick insulated walls, 18” attic insulation and spray foam air sealing to prevent air infiltration. The windows are designed for the orientation. The south windows have a high solar heat gain coefficient (SHGC) to let the solar heat in the winter. The East, West and North windows have a very low SHGC to block the summer sun and prevent overheating. The south windows are shaded in the summer with retractable awnings.
