Energy Efficiency Simulation And Economic Research On Building Envelope Of Energy Conservation Measures In Beijing Area

The high energy consumption in construction has become a heavy burden to the energy of the whole society. Currently the most of the buildings in our country lack the heat preservation and the effective heat insulation measures.In this regard, but also to the outer envelope of the largest energy consumption, at the same time, the building envelope is the largest proportion of the building wall and outside the window, so the building wall and the window energy The development of technology and the reform of wall and window energy-saving insulation is an important issue of building energy saving, which requires us to further promote the development of new peripheral structure technology and related industries, on the other hand, you want to make effective use of building resources, Need to develop more energy-efficient resources.This paper analyzes and studies the building energy problem faced in the process of development in China, and expounds the structure insulation technology outside of the building industry, and uses the theory of partial heat conduction to express the economic benefit of this technology. The comparative analysis shows that dry decoration The exterior wall external insulation system of brick polystyrene board has obvious energy- saving effect. The numerical simulation of the thermal conductivity of the thermal insulation material of the exterior insulation structure by using Fluent shows that the polystyrene board insulation wall can significantly reduce the use of air conditioning and other heating and cooling equipment and improve the service life of building insulation system. Based on the study of energy efficiency of building life cycle, the cost of building construction can be found in the whole process of building the application of the surface energy-saving technology, although the building may need to invest in the early construction of large, but the cost Fully able to use in the subsequent construction of the recovery process, and can play a great role in the protection of the building. Outside the shade structure which can make the building outside the window energy consumption is significantly reduced. In this paper, through the analysis of energy-saving technology application and related energy consumption and income of some buildings in Beijing, the benefits of building energy-saving technology are analyzed from economic efficiency and energy-saving efficiency.Approximate calculation. This paper takes the energy conservation of Beijing Poly Hyde Park apartment as a sample, calculates and analyzes the collected information about the cost of design and construction, and the cost and energy consumption during the construction process. Building investment payback period and other data, I hope this can be the current development and progress in this area to provide a reference, so that energy-efficient buildings in China can get a wider recognition.
