Energy Conservation and Economic Analysis of Public Buildings in Cold Areas
Taking a garbage transfer station in Beijing as an example,a building energy consumption analysis model was established using DesignBuilder software.The economy and energy efficiency of the public building envelope structure in cold regions were analyzed using Guanglianda software and EnergyPlus software,respectively.The optimal insulation material and thickness for the exterior walls and roof of the building were studied to minimize the full life cycle cost of the building and achieve the optimal energy-saving effect.The research results indicate that compared to roof insulation,exterior wall insulation has a greater impact on building energy consumption;XPS insulation board has a higher energy-saving rate than EPS insulation board and rock wool insulation board.When the total investment cost of XPS insulation board is the lowest,the insulation layer thickness is 0.14 m.From the perspective of economy and energy efficiency,XPS board is more suitable for cold regions.
