Study On Comfort And Optimal Design Of Natural Light Environment In Entrance Hall Of Yanqing Winter Olympic Village

With the continuous improvement of the quality of life,people have higher and higher requirements on the indoor physical environment of buildings.The importance of the light environment as the main component of the physical environment is particularly prominent.After the Winter Olympic Village,as a hotel building,more attention should be paid to the quality requirements of the indoor light environment.Among them,the foyer space as the entrance and exit of the building,its sense of experience is particularly important to the first impression of users.Therefore,in order to make the users of the hotel buildings in the Winter Olympic Village adapt to the indoor light environment quickly and bring healthy and comfortable positive emotions when entering and leaving the hall space after the Games.Through the theoretical research,field research,computer simulation,and based on a Ergo LAB305.6 platform provide galvanic skin,ecg and eye movement instrument to measured physical data of the people died as a result of the experiment,the games village hall space is the study of natural light environment,on the premise of saving energy,from the enclosure structure material properties,the form of light and space form three aspects of yanqing games village athlete group can not meet the comfortable light environment demand the hall space optimization design,so as to achieve healthy and comfortable green high standards of indoor light environment.It is hoped to provide a theoretical basis for the reconstruction of the entrance hall space light environment as a hotel building after the Winter Olympic Village and provide a reference for the study of the indoor space light environment of related types of buildings.This paper is divided into six chapters:Chapter 1: Introduction.The background,purpose and significance of the topic selection,the status quo at home and abroad,the content and objectives of the research,the terms and research methods related to natural lighting design and the drawing of the technical route diagram are discussed;Chapter 2: through combing general construction specification and relevant theories of natural lighting,natural light using Muneer&Kinghorn model for yanqing climate condition has carried on the further research,for simulating yanqing six games village athlete group 9provides the reference for the light environment of the foyer space source,at the same time for later scholars of natural light climate provide first-hand information.Secondly,through field research,the natural light environment parameters of the two entrance halls of the athletes’ group 1 with the external structure were measured and the material properties were determined,so as to provide data sources for the light environment parameters needed in the human factors experiment and software simulation in the future;Chapter 3: Through Ecotect and Radiance light environment simulation software,the light environment of 9 hall Spaces of 6 athletes groups in Yanqing Winter Olympic Village is simulated in the four seasons of the year,and the corresponding simulation results of brightness,illumination,lighting coefficient and window brightness are analyzed;Chapter 4: The visual function of 36 ordinary people aged 21-30 was studied experimentally,which provided the basis for the visual function level of the experimental subjects in the human factor experiment in the foyer space comfortable light environment.Through the influence of indoor light environment.Through to affect indoor environmental comfort level of intensity of illumination and affect indoor light glare value window brightness parameters for experiment and research,and analyze the result,the subjective evaluation results and wearable sensors(galvanic skin EDA,ecg and PPG eye pupil diameter)in the data of objective physiological data results,the combination of the research results more scientific and objective;Chapter 5: By comparing the simulation results of indoor light environment parameters of 9 foyers in the previous two chapters under natural light environment with the corresponding illuminance and window brightness parameters required by comfortable light environment of the foyer space in the human factor experiment,it is found that there are three foyers.Therefore,under the premise of energy saving,optimization design is carried out from the three aspects of space form,lighting form and enclosure material attribute,so as to improve the quality of light environment of the four vestibule Spaces under natural lighting conditions;Chapter 6: As the conclusion part,the light environment optimization design of 9 hall Spaces for 6 athletes in Yanqing Winter Olympic Village is summarized.
