One clear pattern seen in high performance houses is that when heating, cooling and domestic hot water loads are reduced, the other loads start to form an increasingly larger piece of the pie. These other loads include lighting, large appliance loads and miscellaneous end use loads (MELs).

Use of pin-base compact fluorescent lamps fixtures reduced lighting loads by roughly a third of typical use. ENERGY STAR® large appliances (dishwasher, refrigerator, clothes washer) installed at this house reduced both electric and domestic hot water loads.
