The Study Of Indoor Nature Ventilation For Office Buildings Based On <evaluation Standard For Green Building>

In recent years, with the continuous development of human society, the acceleratingprocess of urbanization, the increasing number of buildings in cities, the proportion of theenergy consumption of buildings in energy consumption our social total continues to increase.Energy shortages becomes an important problem in social development at present that shouldnot be neglected. So vigorously develop green ecologic buildings is the inexorable trend asfor the development of architecture today.<Evaluation standard for green building> has beenpromulgated and implemented by the Ministry of Construction in2006. Starting from thewhole life process of construction projects, there are some related requirements of economizeon land, power, water and raw materials, indoor environment, operations management, etc. Itprovide theoretic guidance for design and decision-making process of the green buildingprojects. As one of the most important problems of green building, the indoor natureventilation of buildings, not only relates to the indoor comfort and human health, but alsoplay an iimportant role for energy consumption of buildings. Especially for most of thewhite-collar nowadays, who spent about one-third of their daily time in the office, the officeenvironment becomes eespecially important. The research of this article is how to organizeindoor natural ventilation in the office space preferably through appropriate design methodand control technique, so as to provide a comfortable and healthy workplace for users.First, this article starting from the contents of <Evaluation standard for green building>,interprets the related content of wind environment in the standard with building code in detail,and then introduces the basic theory of indoor nature ventilation and wind simulation analysismethods of environment in detail. On this basis, the author analyzes and summarizes thestatus of indoor nature ventilation for office buildings in Hefei by the method of combiningpractical tests with questionnaire survey, and finds the deficiencies of the status. Then on thebasis of the climate environment in Hefei, research various influence factors on theorganization of indoor ventilation such as outdoor environment, building layout, design of thedoors and windows, and so on. Based on comparing the differences the effects of indoornature ventilation under different conditions, we can draw a conclusion about control measureadjustability for office buildings in Hefei. Finally, through the application research of windenvironment control technology for actual project in Hefei and the simulation analysis for theeffect of indoor nature ventilation, the feasibility of control measure on indoor ventilation for office buildings in Hefei should be verified. So that the author wish it could provide somedirection and advice for design and research of indoor nature ventilation for office buildingsin the future of the region.
