Research On Thermal Environment In Xi’an City Commercial Complex

Commercial buildings as a special architectural form along with the changes ofsocial system, the development of social economy, the progress of social civilization,while commercial construction after reform into the modern historical stage, its sizebecome large, forms become diversified, complicated structure, function becomediversified, with the economic system ceaseless and perfect, consumers have higherrequirements at the same time, size of commercial buildings, commercial buildingsindoor comfort also put forward certain requirements; and the context of the globalenergy crisis, reduce commercial building energy consumption is also promoting thenecessary means to the development of green building. Based on this foundation,conducts the research to the indoor thermal environment of commercial buildings.Research for this study is representative of the choice of Xi’an existingcommercial buildings on the basis of investigation of commercial buildings,commercial buildings have a basic understanding of the situation through the fielddetection in indoor air temperature, and then through the subjective questionnaire oncommercial building indoor thermal environment comfort and satisfaction survey, atthe same time on the indoor consumer commercial buildings in different periods thenumber of statistics, so as to obtain the changes of the number of consumers indifferent periods; and the relationship between temperature, Business Hours, thenumber of consumers through the statistical analysis of the data, which reflects theproblems of existing commercial buildings; in order to solve the existing problems,this study uses building simulation technology, modeling simulation of commercialbuilding, and through adjust the boundary conditions of commercial buildings, is similar with the actual situation, on this basis, to obtain commercial indoor airconditioning to simulate the temperature value, the temperature reaches theconsumer satisfaction with the temperature range.Through the research of many commercial buildings, get consumer satisfactionwith the temperature range of values, and through the temperature range value todetermine the changes of air temperature in indoor air of values and the BusinessHours, the number of consumers.
