| With the acceleration of social urbanization,in China,More than 99%of the 2 billion square meters of newly built houses are high-energy buildings,and the building energy consumption accounts for about 27%of the total social energy consumption.The interior and exterior transition space serves as a "bridge" connecting the interior and exterior of the building.Its energy consumption is also huge.With the continuous improvement of people’s living standards,people have higher and higher requirements for healthy life and comfortable life.In the past,people thought that if they want a comfortable living environment,they need to increase building energy consumption,or if they want to reduce energy consumption,they need to reduce the comfort level of the environment.The building energy saving and the comfort limit each others development.Solving its problem is an important content of socialist ecological civilization construction.Therefore,it is of great significance to control the relationship between human life comfort and building energy conservation through reasonable methods.In order to provide people with a comfortable,healthy,green and energy-saving building environment,this paper mainly adopts the objective test and subjective survey of human body comfort and the method of Design builder numerical simulation to discuss this topic from three aspects:(1)Explore the rule of heat and light demand of human body under different temperature sudden state.In the winter of 2017,20 healthy college students were selected as the subjects to carry out experimental research on human heat-light comfort in indoor and outdoor transition Spaces with different energy supply methods.Through physiological parameter test and subjective feeling survey,the change rules of people’s heart rate,skin temperature and subjective feeling vote during the day and night when people change from "cold--neutral--cold" environment were discussed.Transition from experimental data analysis it is concluded that people in the indoor and outdoor space for heat and light to stimulate the response of the different levels,as well as the transition space comfortable temperature and illumination parameter is 14.19℃,and 125 lux.(2)It is very important to plan the excessive space reasonably.Reasonably introduce solar energy to meet the condition of human thermal and light demand,and simulate the energy consumption analysis before and after the transformation of the transition space.To explore the influence of orientation,window-wall ratio and energy supply mode under the condition of satisfying human heat-light comfort,reduce heat dissipation of enclosure structure,conduct simulation analysis of different heat-light contribution degrees,and explore the building energy consumption of indoor and outdoor transition space under the condition of different heat-light contribution degrees,so as to determine the design strategy of different indoor and outdoor transition space.(3)Proposed meet the demand of human body thermal-light of indoor and outdoor building energy efficiency optimization strategy transition space.Although the interior and exterior transition space is not the main functional building of human life,it is a "bridge" connecting the interior and exterior.To make reasonable optimization of the existing transition space and make a rational design strategy for the buildings in the planning.It not only improves the environment of transition space,but also greatly reduces building energy consumption.Therefore,based on the research on the relationship between human thermal and light demand and building energy conservation in the indoor and outdoor transition space in cold regions,to improve the quality of human life,have very important significance,reduce energy consumption of building the transitional space in order to satisfy the demand of human society development provides a new way of thinking,to create human destiny community and is of important guiding significance for energy conservation and emissions reduction. |
