Shape Design Study Of Multilayer Office Building In Cold Region Based On Thermal Comfort Simulation

In recent years,our country’s construction of office buildings has become the fastest growing building type.The potential in energy saving of office building is very huge under the large construction.The comfortable indoor thermal environment is benefit to user’s physical and mental health,improving the quality of living environment.But the improvement and maintain of thermal comfort need to waste a lot of building energy consumption.This paper studies the work way of design parameters between low-energy office building form and indoor thermal comfort in cold region.Through the questionnaire survey and measured about office buildings’ thermal comfort in cold region,get the thermal neutral temperature and acceptable temperature range of users.Then analyzing the office building modeling with different combination of shape parameters,concluded the office building form design strategy to meet thermal comfort with the limition of energy consumption.Research make the architectural design decisions more scientific and provide practical reference for office building sustainable design in cold region.Firstly,this paper analyzes the background and research status,establishes the research methods and framework,and then dissects design parameters of thermal comfort and shape design in office buildings.Then carry out the research measured on site of thermal environment and human body heat acclimation of office building,and concluded that the influence level of thermal comfort parameters,selected the thermal neutral temperature as the judging indexes of simulation in the following research.Finally,this paper summarized the typical morphological parameters through on-the-spot investigation to office building in cold region,and carried out the simulation analysis of different parameters,such as architectural plane form and orientation,the total length width and depth,and height of the coupling.Make the indoor temperature as a characterization of thermal comfort level,Obtain the office building shape optimization design strategy based on thermal comfort simulation.
