Abstract: This paper reports study on life cycle commissioning for a university facility. In this building, commissioning in the whole fields of architecture has been conducted since planning phase. Total energy consumption in operation phase was calculated in the final stage of design phase. The predicted value was compared with required condition of OPR (Owner’s Project Requirement) to examine the validity of design. Then, performance in operation phase was examined by means of comparing measurement value with predicted value. According to the examination, it was found that there was difference between design and measurement values for the use of air conditioning. In this paper, as a commissioning in operating phase, causal factors for difference of the energy consumption for air conditioning were extracted by analyzing measurement data. The influence of each causal factor was confirmed by simulation using LCEM tool. This paper proves that LCEM tool is useful through the life cycle commissioning by above mentioned verifications.
