Research On The Optimization Design Of Natural Lighting Environment Based On Visual Comfort Evaluation

Natural light as a kind of green energy is inexhaustible, compared with artificiallighting, natural lighting is more advantageous to the user’s physical and mental health,for a long time people have reached a consensus: use in the construction of the naturallight can save lighting energy consumption. Natural light has many positive effects on thehuman body, such as: to improve work efficiency, soothe the nerves and so on. Naturallighting effect can not be ignored, but the advantage of natural lighting in the constructionindustry of China has not been given sufficient attention, lighting design is not in thearchitectural design process has not formed a professional lighting design, bad is notconducive to building energy efficiency and the impact of indoor lighting comfort.Sufficient natural lighting full of architectural space, not only can save building energyconsumption, but also beneficial to people’s physical and mental health. In recent years,the increasingly serious environmental problems, resource problems are more and moreprominent, more and more attention have paid to the architect energy-saving potential ofnatural lighting. How to make good use of natural light to ensure indoor full lighting hasbecome an important topic. Taking high-rise office building in Chongqing area as theresearch object, optimization design of the natural light environment of office buildingsare studied, discussed in the design stage, how to comprehensively considering variousfactors to optimize the design.The full text is divided into5chapters, in order to put forward the question, analysisquestion, solves the question mentality:The first chapter, introduction. This thesis topic, proposes to use the office buildings,glass curtain wall of the huge energy consumption, also cause light pollution, summarizesthe purpose and significance of research, research, research methods on general, do aliterature review on the current domestic and foreign research situation.Related concepts and theoretical research, second chapter. The development historyand lighting of office buildings in Chongqing, analyses the light climate characteristics,provides the theory basis for the next step research survey.The third chapter, analysis, investigation, different forms of windows, investigationof human visual perception and the interior light environment, and on this basis,according to the statistical data are compared, which can determine the initial impact ofvisual window form of human feelings formation. The fourth chapter, the preliminary study, based on the visual theory, using thequestionnaire survey method of visual perception for different window size and formwere studied, the different individuals of different shape, size and position of windows onthe perceptual effects.The fifth chapter, the optimization strategy, on the basis of the above study, bothlighting and comfort requirements, put forward a method to optimize the office buildingindoor natural light environment design, namely the reasonable planning based on thephase of the programme, to effectively control the window form, optimization is designedto achieve the visual comfort and lighting, energy consumption.Sixth chapter, conclusion and prospect, summarizing the office building inChongqing area of natural light environment design research.
