| The application of solar energy technology in the building can reduce the consumption of fossil energy and reduce the carbon emission in the whole life cycle of the building,which is of great significance to environmental protection.All countries in the world are doing a positive research on the technology of solar energy utilization,but the research on the integration of solar energy utilization technology and architecture has not reached a consensus.The contents of this paper are belong to one part of the Shaanxi province science and technology co-ordinate innovation project project project<<The research and promotion of the green house system of the original bamboo and keel composite structure>>(Project number:2016KTZDSF04-02-02),In order to ensure the smooth completion of the project,this paper has undertaken the research on the solar energy utilization measures of a new type of composite structure green house.Based on the green housing system of the original bamboo and keel structure,the optimum utilization method of solar energy in the system is analyzed through the methods of structural diagram,optimization analysis and software simulation,at last produce the design scheme of the demonstration building.The original bamboo joist composite structure adopts the new spray type environmental protection wall as the enclosure structure.In order to ensure that the building has good energy saving effect,the paper analyzes and optimizes the structural level of the original bamboo keel composite structure wall at first.On the basis of the mechanical research results of the research group,the construction method of the solar energy technology utilization node in the original bamboo keel composite structure system is analyzed and designed.the sketch map of node construction is drawn as thebasis for the construction of demonstration buildings.Based on the design concept of passive solar house,the solar energy utilization mode is optimized to find the best form for solar energy utilization.For example,determined the value of the area ratio of the window wall,the optimal design of the additional sunlight and the arrangement measures of the regenerator should be added.In order to ensure the demonstration building should be successful completion,four sets of demonstration building design options are presented in the paper.The four sets of plans are different in the design style and the building area,and the space use area of each function is also diversified to meet the individual needs of different households.In the design process of the project,we always aim at saving energy and improving the indoor thermal environment quality,in order to providing a comfortable and economical living environment for the residents.The scheme uses a variety of passive and active solar energy utilization technology,to analyses and calculates the operating conditions of passive solar energy utilization technology and the heat collection of solar hot water system..Use the computer software Energyplus to compared the optimization model and the standard model.The results show that the energy saving effect of the optimized model is remarkable,and the efficiency of heating energy saving can reach 32.8% in winter.In order to ensure the good energy saving effect and the indoor thermal environment quality,the main functional space of the optimized model is further simulated and predicted in the winter heating period and the summer cooling period.Combined with the simulation results,the indoor thermal environment quality is analyzed,and the improvement measures are put forward.Suggestions for improvement are made for the problems in the simulation results.The research results of this paper enrich the utilization of solar energy technology in the original bamboo structure housing,which can significantly improve the efficiency of solar energy utilization and the energy saving efficiency of the new type of original bamboo and keel composite structure,which plays an important role in the further development of the system. |
