Assessing the potential of applying energy saving measures and renewable energy resources in the campus of Lund University

Abstract: Several problems concern about energy are frequently discussed in recent decades, such as the shortage of traditional energy resource, the increase of energy price and the destruction of living environment by energy conversion. To solve these problems, sustainable development of energy become a preferential task all around the world. Under current circumstances, applying energy saving measures and using renewable energy resource are two of the best choices. The goal of this study is to assess the potential of applying energy saving measures and adding renewable energy resource for two object buildings inside the campus of Lund University in Sweden. Heating and cooling energy consumption calculations towards both buildings were performed for both current and future climatic conditions. Meanwhile, the potential of adding solar energy, wind energy and shallow geothermal energy were investigated. Also, the economic profit and environmental feasibility were estimated through life cycle cost and life cycle assessment. For applying energy saving measures perspective, results show that adding insulation material to old walls, adjusting heating and cooling set point, applying high-efficient heat recovery system, and adding shading device would have significant effect on decreasing heating or cooling energy consumption. Moreover, heating and cooling energy consumption in future scenarios would decrease and increase respectively, which indicates the same phenomenon as the trend of global warming. From adding renewable energy resources perspective, the results show that the campus of Lund University have enough potential to apply solar, wind and shallow geothermal energy resources by installing PV panels, small-scale wind turbines and ground source heat pump. Besides, future climatic condition would not have huge or certain influence on renewable energy applications.
