Study On The Feasibility Of Passive House In Multi Storey Office Building

With the increasingly serious global energy crisis and the deterioration of the ecological environment,energy conservation and emission reduction have become an important issue in the world.Today,China's environmental carrying capacity has reached or close to the upper limit,in line with the people's expectations of a good ecological environment,promote the formation of green low-carbon cycle development is imperative.In our country,the building energy consumption accounts for about 1/3 of the total energy consumption,while the number of public buildings accounts for about 1/3 of the total urban construction."11th Five-Year" plan proposed to transform both energy-efficient office building for the pilot,planning to carry out energy-saving renovation of existing public building,establishment and implementation of energy-saving rate of 50% of the existing "standard" energy saving renovation of public buildings;"12th Five-Year" plan implementation of public building energy consumption per unit area decreased by 10%,among them to reduce the energy consumption of large public buildings energy-saving target of 15%.All above shows that the development of energy-saving public buildings is the inevitable requirement of building energy conservation and national policy.The passive room technology can reduce the energy consumption of the building,which is the most simple,the most cost-effective and the most favorable to the environment in the construction area.Therefore,it is of great significance for the development of energy saving in our country to learn from the passive housing design strategy.Based on the above problems,this study is aimed at the problems of energy saving in multi storey office buildings,taking Dalian city as an example:(1)Combing the development process,design principle,energy consumption and energy consumption of office buildings.Understand the advanced design concept and the energy saving of the office building,so as to provide reference and reference for the application of the passive house in the multi-storey office building.(2)Such investigation of eco technology innovation in Dalian City office building,favorable conditions and feasibility analysis of passive real possibility in the eco technology innovation city,put forward opinions and suggestions,to promote the development of passive housing in the eco technology innovation city.(3)The feasibility of induction strategy in real passive multilayer office building on the design from the qualitative point of view,from the quantitative point of view,office building in the actual case,the building energy consumption simulation by software,analyzing by comparison,choose reasonable passive design strategies,and ultimately make the building to meet the load index of passive house in the standard.The above two aspects will provide reference value for the future construction of multi storey office building into a passive house.This research belongs to the field of architectural design and architectural technology.The research involves passive housing and office building energy-saving technology,hasmade many aspects of passive and feasible design strategies,hoping to improve the theory research in the field of China,and has guiding significance to the actual engineering construction.
