Analysis And Research On Sensitivity Of Energy Consumption In Comprehensive Gymnasium In Cold Area

With the rapid development of human civilization,many problems caused by the over-exploitation and utilization of earth resources have sounded the alarm for us.As a city's iconic building,large public buildings account for a huge proportion of building energy consumption.As an important part of large public building,stadium have a variety of shapes and and huge space scales,which is undoubtedly at such a high energy consumption level.Facing the vigorous development of sports career and the increasingly fierce construction of stadium,the green energy-saving design of stadium has high research value.In response to today's problems,green building design blindly seeks high-tech technology and equipment,unable to focus on energy saving design,lacking systematic and comprehensive building design data basis and theoretical knowledge.this article aims at energy saving and emission reduction,from the perspective of building design,based on the northern region stadium data collection and specifications,use simulation software to conduct single-factor and multi-factor energy consumption sensitivity simulation experiments.study the changing characteristics of various design factors that affect the energy consumption of stadium,calculate the energy sensitivity sensitivity and weight of each design factor.Better guide the green building evaluation and green design practice of stadium in the future.The research ideas provide reference for related research on different types of tall space public buildings in other regions of my country.It will also help to achieve the goal of energy conservation and consumption reduction in the construction industry.To achieve the goal of standardizing high-level,high-performance sports buildings and low-energy buildings..First,analyze the current development prospects and existing problems of energy consumption and green design of stadium,determine the research background and research significance of this article,clarified the concepts related to the comprehensive gymnasium in the cold area,building energy consumption simulation,sports building database and building energy consumption sensitivity analysis,and the overall research process is proposed.Secondly,Through the preliminary information collection of sports construction data in10 provinces in cold regions,determine the data collection principles and research methods.At the same time,Conduct field technical research on some venues and summarize the basic working conditions,supplement and improve the database information and collection content.Classified according to the collected data,using Access software to build a cold stadium database.Thirdly,based on the information extracted from the sports building database,comprehensive relevant specifications and literature,building large and medium-sized typical reference model from the environmental climate layout,space design,enclosure interface structure design,HVAC system,indoor load and operating frequency.As much as possible to ensure that the typical reference model is accurate and reasonable.It is clear that the data of each parameter comes from the setting basis.At the same time,determine the energy consumption sensitivity analysis process and the operating principle of the simulation software to ensure that the simulation experiment is smooth and the results are accurate.Fourthly,through the specific analysis of the application of the sensitivity analysis method,determine the principle of the specific method based on the local sensitivity analysis.The energy consumption sensitivity analysis of individual design factors for medium-sized and large-scale gymnasiums is carried out from the layout space scale,building shape,enclosure interface,and equipment operation.Analyze the relationship between various design factors and building energy consumption,and determine the key design factors in energy-saving design of medium-sized and large-scale gymnasiums.Finally,based on the relevant indicators of energy saving contribution rate and sensitivity coefficient derived from the simulation results of single-item sensitivity analysis of medium-sized and large-scale comprehensive gymnasiums,three data types of spatial scale,window-to-wall ratio,and K value of enclosure structure are selected.Taking the medium-sized comprehensive gymnasium as an example,the factorial design method is used to conduct a multi-design factor energy consumption sensitivity experiment on some design factors.Using SPSS software to analyze the statistical results of ANOVA and Multi-factor linear regression,analyze the interaction between the overall influence law and factors,and explore the simultaneous change of multiple design factors and the correlation and change regulation of building energy consumption.
