The energy consumption for air conditioning in summer is one of the main energy consumption for buildings. Reducing the summer power consumption has become an important research direction of sustainable development in subtropical regions. This research mainly studied five different energy-saving measures for reducing building energy consumption in summer, and their numerical simulations. The real experimental data were used to verify the simulation results for the power consumption of air conditioners. The reliability and accuracy of the simulation software were validated by some examples. Three kinds of analysis software: eQUEST, DesignBuilder and Ecotect were used in this study. By comparison between simulated data and real experimental data, the method of simulating real situation, its feasibility and applicability were discussed in very details. In this research, two experimental houses were set up to conduct five groups of comparison experiments for different energy saving measures, including those for the external wall heat insulation, roof insulation, internal shading, external shading, and the reduced opening rate of windows. The angle-adjustable sunshades were used in external shading experiments. The internal shading is through the device installed in the inner side of the transparent enclosure, such as the curtain. Heat insulation measures for wall and roof insulation experiments are the installation of thermal insulation layers which were embedded in walls or roofs to protect buildings from inflow of heat. The heat insulation materials used in this research are EPS. Window opening rate is one of the important factors of energy saving. In the premise of ensuring the lighting, decreasing the window opening rate can reduce the air conditioning power consumption. The half size of the windows was used in the experiment. The best effect on reducing air conditioning power consumption for experimental houses is the exterior thermal insulation and shading, followed by shading and roof insulation. The power-saving effect for reduced opening rate of windows is the worst. In five groups of experiments, three kinds of building energy consumption simulation software, eQUEST, DesignBuilder, Ecotect were used for air conditioning power consumption simulation. In order to better simulate the real situation of buildings, the simulation methods were surveyed and tested in details, including the exploration of the shading inter-influence between the experimental houses, and the influence of different modeling methods. The simulation results of ASHRAE are more reliable and accurate than DesignBuilder and Ecotect. Among five groups of experimental results, the simulation results of DesignBuilder for air conditioning power consumption are the closest to the experimental results. The energy saving rate of three kinds of simulation software is slightly different from the experimental data. The energy saving efficiency of roof insulation is generally lower.4950025 bytesapplication/pdf論文公開時間: 2018/8/3論文使用權限: 同意有償授權(權利金給回饋學校)建築能耗模擬節能實驗eQUESTDesignBuilderEcotectBuilding energy consumption simulationEnergy saving experiment[SDGs]SDG7建築空調耗能模擬之不同軟體對比與實驗驗證Experiment and Simulation of Building Cooling Load by Different Analysis Toolsthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/278209/1/ntu-104-R02521251-1.pdf
