Research On Dynamic Skin Design Of Office Buildings In Severe Cold Region Based On Daylight Comfort

With the development of urbanization,more and more office buildings are emerging,and the energy consumption of office buildings has become one of the key issues that architects pay close attention to.In recent years,as an important research direction to solve the energy consumption problem of office buildings,daylighting has been used more and more widely.daylighting has many advantages that can not be replaced by artificial lighting,such as economy,energy saving,comfort and so on.But daylithting also has its shortcomings.With the change of time,it is difficult to maintain a stable level of indoor daylight environment,so there will be many problems,such as glare,excessive illumination and so on,affecting the comfort of office buildings.As an indoor and outdoor interface,building skin has an important impact on the stability of indoor daylight comfort Dynamic skin can respond to changing environment dynamically,and enhance the stability of indoor daylight comfort.Based on the above background,this paper combs the key points of dynamic skin design,and establishes a dynamic skin model based on cold office units.The effectiveness of dynamic skin enhancement is proved by the measured method.Firstly,the related theories of dynamic epidermis,as well as the related theories of daylight comfort,daylight environment and dynamic epidermis influencing factors in cold regions are combed.Secondly,on-the-spot investigation of existing office buildings in frigid areas,the main factors affecting indoor daylight comfort are established,and the feasible morphological model of dynamic skin of office buildings is established.On this basis,through the simulation of daylight comfort performance,the reasonable dynamic skin shape is selected,and the dynamic skin control strategy is established.Finally,the dynamic skin scale model is established,and the feasibility and rationality of the dynamic skin model are explored by means of artificial sky dome and other experimental equipment from two angles of daylighting and glare.The research results show that it is feasible and necessary to construct dynamic skin model of office buildings in severe cold regions based on daylight comfort.Using this model can greatly improve the comfort,improve efficiency and save energy consumption.
