Field tests of various combinations of electric, energy conserving appliances were conducted in 16 homes in Orlando and 12 homes in Miami. The appliances tested were central air conditioners, ceiling fans, heat pumps, heat recovery water heaters, dedicated heat pump water heaters, and refrigerators. The purpose of the tests was to measure the actual reduction in energy use associated with various combinations of conserving appliances. With the exception of the refrigerators, all tests were conducted with both a conventional unit and a high efficiency unit in parallel in each test site. These were used alternately on a weekly basis so that energy use for baseline and high efficiency units was measured in the same house with the same family. In addition, in each city, the houses were in a development of similar houses. Roughly half the homes had high efficiency refrigerators. The tests ran from January through August of 1982. Results show significant variations from house to house with the same appliance and a reduction in enegy use with the efficient refrigerators, heat pump water heaters, and air conditioners. Results for ceiling fans showed no savings for the average of all the sites although those sites which had larger than average air conditioning loads had significant savings. Heat recovery water heater tests showed savings in Miami where new heat recovery units were installed for testing. At the sites in Orlando where existing heat recovery units which had been in service for 2 to 5 years were tested as installed no savings were found. Heat pump tests were inconclusive due to limited data.
