Low Energy Consumption Design For The Entrance Space Of A Cold-area Theater Building In A Comfortable Thermal Environment

As the development of the construction industry becomes more and more perfect,the thermal comfort of the indoor space environment of the building has aroused widespread concern.However,to ensure the thermal comfort of the indoor environment,HVAC designers usually set up mechanical equipment to meet the demand.Under such premise,the heating and air conditioning energy consumption of the building space is increasing.However,even if the energy consumption of building operation is increasing,the improvement of indoor thermal comfort is not satisfactory.The reason for this is that the designer lacks an understanding of the relationship between the physical thermal environment and thermal comfort,especially in cold areas.Under the climatic environment,there is a large gap between the outdoor temperature and the ideal indoor thermal environment,and the problem of energy consumption is more serious.Related research is urgently needed.Based on the above background,this article takes the entrance space of the cold theater building as the main body of research,and at the same time selects the typical theater entrance space for field research,measures the indoor thermal comfort of the objective data and issues a subjective questionnaire,on this basis,summarizes different designs Variables and specific user groups affect the degree of indoor thermal comfort and operating energy consumption and operating rules.Therefore,the low energy consumption design of the entrance space of the cold theater building with thermal comfort as the basic goal is proposed,and it is verified by software simulation analysis.The thesis is divided into five parts.The first part summarizes the background significance of the research,defines relevant concepts,and determines the overall research framework of the thesis.The second part starts with the study of the development history of theater architecture space,establishes a database of cold-area theater architecture,comparatively analyzes the value range and spatial scale range of different types of theater entrance space design features,and at the same time explains the basic theory of thermal comfort as discussed later in accordance with.The third part selects the entrance spaces of three typical cold theater buildings to conduct on-site measurement and subjective questionnaire survey on the indoor thermal comfort to understand the current characteristics of the space thermal comfort and the situation of the users;The analysis of relevant design codes determines three types of typical models: the scale of the front-end,allinclusive and ring-shaped inlet space models,and the heating,ventilation and air conditioning HVAC parameters as the prerequisites for thermal comfort and energy consumption simulation.The fourth part is based on the design variables that affect the thermal comfort and energy consumption of the entrance space of a typical theater under cold climate conditions including orientation and window-to-wall ratio,thermal performance of the envelope structure and the use of shade size.Using Ladybug & Honeybee software for simulation analysis,and find the optimal combination of design variables by controlling the simulation results.In the fifth part,based on the simulation results and related theoretical analysis,the strategy for the low energy consumption and thermal comfort design of the cold space theater entrance space is obtained.The typical model summarized in the thesis aims to provide guidance and reference data model for the design of the entrance space of the cold theater,and the simulation analysis results can be used by the designer to clearly design the focus of thermal comfort and low energy consumption in the scheme design stage.The design strategy mentioned in this article is not limited to the single type of entrance space of the theater building,it belongs to a general method system,and can also be applied to other building types.
