A Case Study of Campus Building End Use of a University in Norway

Abstract

Energy use in university campus plays an important role in energy use of the society, because universities are complex infrastructure and they are similar to small towns. A university campus consisted of 35 buildings, with total area of approximately 300 000 m2 was analyzed. Six-year energy uses of electricity and heating of 24 buildings in one university campus in Norway were selected as case objects monitored by Building Energy Management System and web-based Energy Monitoring System. Descriptive statistics were applied to analyze energy use and influencing factors on energy use. The coincidence factors for both heating and electricity were calculated. The results indicate that the energy use of the whole campus were obtained as101 kWh/(m2a) for heating and 200 kWh/(m2a) for electricity, respectively. Regarding the individual buildings, the electricity use was 170± 89 kWh/(m2 a) and the heating use was 169± 115 kWh/(m2 a) for heating with a few exceptions of over 300 kWh/(m2 a). The influence of seasonal factor on heating was much higher than on electricity. The coincidence factors of heating were 0.96 in working day and 0.87 in weekend. The coincidence factors of electricity were 0.99 and 0.98, respectively. The results from the study could be used for energy planning of cities and other urban energy systems.
