This article summarizes a methodology developed to evaluate the energy savings impact of HVAC maintenance training for community colleges in California. The methodology was developed in a study conducted jointly by Servidyne Systems, Inc. and the California Energy Commission. The study involved: 1) a review of previous literature on attempts to quantify training and preventive maintenance impacts; 2) creation of a simplified calculation model for estimating energy savings that could be attributed to HVAC maintenance training; 3) application of the model to nine sample community colleges, using data taken from energy audits of the colleges; 4) calculations of the range of energy savings that could be anticipated through training at the nine colleges; and 5) field surveys to evaluate HVAC equipment conditions and document typical maintenance problems at community colleges that could be addressed by a training program.
