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.

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. Besides, with the rapid growing demand of housing, the energy consumptions of buildings increase dramatically, which is equivalent to approximately 48% of total energy use in Sweden. Meanwhile, traditional energy resources like coal, oil and so on are still the main resources to produce both thermal energy and electricity. Moreover, since Sweden is located in high latitudes with extreme cold climatic condition, more heating energy consumption would be needed to keep a satisfied indoor environment. Phenomenon above...

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. Besides, with the rapid growing demand of housing, the energy consumptions of buildings increase dramatically, which is equivalent to approximately 48% of total energy use in Sweden. Meanwhile, traditional energy resources like coal, oil and so on are still the main resources to produce both thermal energy and electricity. Moreover, since Sweden is located in high latitudes with extreme cold climatic condition, more heating energy consumption would be needed to keep a satisfied indoor environment. Phenomenon above lead sustainable development of energy become a preferential task in Sweden.
Under current circumstances, applying energy saving measures and using renewable energy resource are two of the best choices. The main objective of the study is to assess the potential of applying energy saving measures and adding renewable energy resources in both current and future climatic conditions in the campus of Lund University in Sweden. The scope of this project is to investigate the energy performance of two object buildings for current and future climatic conditions as well as considering the potential of applying possible retrofitting techniques. The two buildings are the IKDC and M-huset, both are a part of the LTH in Lund. M-huset was built in 1960s and it was regarded as a representative of old construction in this study. The IKDC was built in 2002 and it was considered as a typical modern construction for comparison with M-huset. Besides, the potential assessment of adding renewable energy resources performing for the whole buildings in the LTH campus is also investigated for current and future climatic conditions. Also, the study of Life Cycle Cost and Life Cycle Assessment were carried out for long-term economic profit and environmental protection point of view.
Five phases were carried out in this study. First, literature review phase was done for energy saving techniques, renewable energy resource applications, life cycle cost and life cycle assessment. Second, heating and cooling energy consumption calculations towards two object buildings were performed for both current and future climatic conditions in IDA ICA. Future climatic conditions were simulated based on the TDY, ECY and EMY weather file for the period of 2009-2038, 2039-2068, and 2069-2098. Third, energy saving measures were applied and simulated for M-huset as a representative. Then, the potential of adding solar energy, wind energy and shallow geothermal energy for whole buildings inside the LTH campus were investigated through Rhinoceros, System Advisor Model, Autodesk Flow Design, WRPLOT View, and G.POT method, which were also estimated for both current and future climatic conditions. Last but not least, the economic profit and environmental feasibility were estimated through life cycle cost and life cycle assessment for building retrofitting measures and renewable energy applications.
From the masses of results, several valuable conclusions were drawn. 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. It is also important to consider environmental protection and economic profits together with local climatic condition when choosing retrofitting methods for buildings.
From assessing the potential of adding renewable energy resources perspective, the campus of Lund University has enough potential to apply solar, wind and shallow geothermal energy resources by installing PV panels, small-scale wind turbines and ground source heat pump. For solar energy, PV module materials like monocrystalline has the highest efficiency and generation than polycrystalline and amorphous. Moreover, 40 degrees inclination of PV modules shows the highest annual power generation when modules are fixed. Besides, to cover the electricity consumption in M-huset only seven times bigger scale of the PV already installed would be need, which indicates it is possible since M-huset still have plenty of available roof areas. Whereas, the energy consumption in winter is hard to reach for space limitation. For wind energy, big scale and horizontal blade wind turbines have higher efficiency, shorter investment payback time, and lower environmental burden than small-scale and vertical blade wind turbines. However, space limitation and acoustic pollution makes the small-scale wind turbines become the optimal choice when applying wind energy inside the campus. For shallow geothermal energy, G.POT method is a preliminary but useful method to assess the potential. Although local ground condition is hard to change, deeper and bigger boreholes would lead to a higher shallow geothermal potential.
For future climatic condition, heating and cooling energy consumption would reduce and increase respectively, which indicates the same phenomenon as the trend of global warming. Besides, future climatic condition would not have huge or certain influence on renewable energy applications. Although majority of wind speed would slightly lower down in future, no certain variation trend was find for solar energy and shallow geothermal energy in this thesis. (Less)
