3 Assessment Home Energy Survey A home energy survey is a visual inspection that doesn t include the use of diagnostic testing equipment. Its purpose is to assess the general energy performance of an existing home including: Building envelope features (windows, doors, insulation, ducts) and ages. Heating, cooling and ventilation equipment types, characteristics and ages. Appliance and lighting characteristics. Comfort complaints. Visible moisture issues. Visible health and safety issues. Assessment General Energy Audit It expands on the home energy usage, as well as a more thorough financial analysis of its energy costs. The general energy audit also includes diagnostic testing using specialized equipment such as a blower door test, duct leakage tester, combustion analyzer and infrared camera. These tests are done to determine: The location and number of air leaks in the building envelope. How much leakage is occurring from HVAC distribution ducts. How effective is the insulation inside walls and ceilings. Any existing or potential combustion safety issues. Conservation (Everyday) Install a programmable thermostat to lower utility bills and manage your heating and cooling systems efficiently. Plug home electronics, into power strips; turn the power strips off when the equipment is not in use Lower the thermostat on your water heater to 120 F. Use low flow showerheads for additional energy savings. Efficiency (Long Term) Install a programmable thermostat to save up to 10% on cooling and heating costs. Change to new and improved light bulbs. Reduce energy use from about a third to as much as 80% with today s increasing number of energy efficient halogen incandescents, CFLs and LEDs. Seal air leaks and properly insulate to save up to 20% on heating and cooling bills, while also increasing home comfort. Alternative Energy Solar Energy 3

5 Building & Site Assessment Orientation Do You Have Enough Space? Got Shade? Solar PathFinder 2kW system in Arlee, MT West The rule of thumb for PV panels is 100 square feet of space is needed for every kilowatt (kw) of electricity produced. For thin film PV materials (such as solar shingles), about 175 square feet of space per kw is needed. Solmetric s SunEye What s Your Angle?
