Location (general information, house shape and size, and exterior shading)
Structure (air tightness, foundation & floor, walls, doors & windows, skylights, and attic & roof)
Systems (ducts & pipes, thermostat, heating, cooling, water heating)
Large Appliances (refrigerators & freezers, cooking & dish washing, laundry, hot tubs, spas, and pumps)
