In a follow-up study of the energy conservation potential for the correct operation of air conditioning equipment in a commercial building, Honeywell Systems and Research Center modified the previous assumptions and compared July 1973 results with July 1974 results. As 80/sup 0/F was considered too high for employee comfort, all thermostats were set at 78/sup 0/F, and time programmers were installed to turn the 2 rooftop units on at 7 a.m. weekdays and off at 6 p.m. Override switches allowed a group working a late shift (10 hr/week average) to turn on one of the rooftop units at night. Even though July 1974 was the hottest July in decades, energy consumption was 50 percent less than July 1973, despite the great increase in cooling load. The 55 percent apparent savings in cooling energy appears to reasonably reflect computer prediction. Without submetering and complete instrumentation, it is impossible to normalize field and computer simulation data. Commercial buildings of this type (1-story, flat-roof) have great potential for saving money and energy by raising summer-cooling thermostat settings. Commercial buildings have greater potential than residences for savings using higher thermostat settings. Submetering the cooling equipment could be most helpful in justifying higher summer temperatures in commercial buildings.
