Abstract: This is a study focused on energy-saving guidelines for non-residential buildings. These guidelines are important in order to promote and spread the implementation of the energy-saving techniques in HVAC system for non-residential buildings. In this study, three factors are taken into consideration (i.e., thermal load factor, design factor and operational factor) which affect the energy consumption of the buildings. Then, a case study concerning these factors is conducted and the effects were compared with various energy-saving techniques. To evaluate the energy saving technique by the Life Cycle Energy Management tool (LCEM), we assumed model buildings as prevailing office buildings. As for thermal load factor, we set internal heat gain caused by office automation facilities, 20W/㎡, 40W/㎡ and 60W/㎡ respectively. As for operational factors, we supposed that different cases result in different usage ratio since usage seemed vital in different aspects. In this paper, we evaluated 6 energy-saving techniques [i.e., optimization (for intake outside air volume), total heat exchanger, suitable fans, adaptation of VAV (Variable Air Volume) control, adaptation of VWV(Variable Water Volume) control, and preventing of short-circuit in outdoor units.
