Abstract : This thesis develops a straightforward and accurate method to determine mechanical heating system changeover timing. Transitional season weather causes buildings to stay within acceptable thermal comfort ranges without requiring supplemental heating. Significant energy savings can be realized if heating plants can be shut down during periods they are not required. The term 'trigger temperature' is used to describe the minimum acceptable comfort conditions which must be maintained before changeover can be made. Computer simulation of ninety-four hypothetical office buildings is used to record data for hourly building temperatures. Statistical regression analysis techniques are employed to analyze the data and develop temperature prediction models for a range of building envelopes and occupancy schedules. Hand calculation and micro-computer applications are offered to provide changeover decision criteria for facility managers using this method.
