Study On Natural Light Environment Parameters And Optimization Strategy Of VDT Behavior In Office Space

In the 21st century,social change,economic development and technological progress have made great changes in the functional attributes,spatial layout and activity demand of office space.Under the background of this era and the promotion of related technologies,the low-cost and efficient VDT Operation gradually replaced the traditional operation mode as the main office mode of the enterprise,and the concept of paperless office has penetrated into the whole industry.The optical environment comfort of office space has always been a research hotspot in the academic field,but at present,the domestic optical environment design specifications are not only lack of VDT work content,and the update is not timely,the data is also difficult to meet the VDT work needs,unable to meet the actual situation.On the basis of practical investigation,this paper takes VDT Operation behavior as the core,individual psychological and physiological subjective comfort as the benchmark,conducts quantitative research on the index parameters of office space light environment,and probes into and supplements the rational development of office space light environment.Firstly,this paper describes the research background and existing problems of VDT work and office space light environment,and studies the spatial characteristics,spatial parameters,visual characteristics and visual influencing factors of VDT work behavior in specific literature and network research.Combined with the specific characteristics of VDT Operation Behavior,the light environment parameters(vertical illuminance and luminance threshold)of specific office space were studied.Combing the existing literature research,selecting typical office space samples,through on-site interview,questionnaire survey and field measurement,the paper conducts a real investigation on the characteristics of VDT Operation Behavior and the basic situation of office space light environment,summarizes the existing problems,and compares the performance of the same indicator in different light environment.Then through the way of experiment to study the specific index parameters,try to determine the specific parameter range.Finally,the optimization strategy is put forward from the design point of view.This paper mainly includes the following five parts:The first part of the introduction:through the research status at home and abroad to build a research framework,to the current problems in the VDT operating environment as the research content,to find suitable research methods,at the same time,to clarify the significance and purpose of this study.The second part of the basic theoretical research first defines the relationship between people,behavior and environment from the perspective of behavioral psychology,then studies the spatial characteristics,visual characteristics,environmental indicators and other factors of VDT Operation Behavior,and determines illuminance,evenness,glare and color temperature as the environmental indicators that affect VDT Operation,and advances the actual behavio of VDT Operation and the light environment status of office space We did preliminary research.This paper analyzes the importance of illuminance and evenness,glare and color temperature from three aspects of work impact,research status and space impact,and determines that the next research focus is the illuminance value and glare index of vertical working face.In the third part,the research on illuminance index of vertical working face firstly summarizes the relevant literature and research results,conducts field research on typical office space samples,and analyzes the existing problems.According to the research results,the illumination index of the vertical working face is studied,and the comfortable range of the illumination is determined.The fourth part is glare index research.Firstly,the relevant literature and research results are summarized.In order to break through the limitations of glare formula,the brightness threshold under absolute glare is studied.Conduct field investigation on typical office space samples and analyze the existing problems.According to the research results,the luminance threshold index was studied.Determine the comfort range of luminance threshold index.The fifth part of the optimization strategy part of the lighting indicators,architectural form,window design,furniture layout of these four aspects of the proposal.The sixth part of the conclusion and outlook part summarizes the research results of the office space light environment indicators,summarizes the lack of the article and the content that needs to be studied,and looks forward to the future research.
