Colleges And Universities Architectural Design Strategies With Low Energy Consumption In The Northern Cold Regions

In 2014, China's fuel consumption has accounted for 23% of the world's total consumption. The building has become the main part of energy consumption and carbon emissions, energy consumption accounts for about 39% of total energy consumption. In 1999, the Ministry of Education called on that China's higher education enrollment rate need to increase from 9% to 15% in 2010, so all over the country began to build and expand campus. According to the statistical data in 2005, the total energy consumption of China's colleges and universities to 17.9 million tons of standard coal, accounting for 8% of the country's total energy consumption, the total water accounted for 6.6% of the municipal water supply, per capita energy consumption and water consumption level were higher than China's per capita living energy and water level. By the end of 2013, the number of colleges and universities reached 2788, students of about 3499 people, school area of 768.81 million square meters, of which the northern cold regions share ratio reached about 50%. Moreover cold area in winter use of centralized heating mode, energy situation is particularly grim.Taking the universities and colleges buildings in the northern cold regions of China as an example, set forth by the relationship between climate and thermal comfort and energy consumption, propose the passive energy conservation strategy based on thermal comfort characteristics. Firstly, according to energy consumption and indoor thermal environment data of Universities and Colleges to analyze energy consumption and indoor thermal environment situation.Then using climate consultant software to simulate building passive strategy of six typical urban (Dalian, Beijing, Shijiazhuang, Jinan, Taiyuan, Zhengzhou) of northern cold region by "climate adaptation model" as indicator. Under the analysis of the strategy effectiveness index, conclude that the external envelope structure is the main energy consumption factor. Combine with the problems existing in the north cold regions of the universities and colleges to find out how to improve thermal insulation properties of exterior wall, roof and exterior window.On the basis of the above two chapters conclusion, simulate case building annual load and natural room temperature with the most widely used energy conservation simulation software DeST. By analyzing the energy conservation effect of the external wall, roof and external windows before and after the transformation, obtain the optimal energy conservation transformation strategy. Optimize and combine the above effective strategy, through the comparison of the data to evaluate and verify the energy conservation effect. The best one is the most suitable strategy for the construction of the northern cold regions.This paper count up the total energy consumption of different functional buildings in campus and electricity consumption of case building, actual measurement indoor thermal environment of typical building in colleges and universities, in addition use software Climate Consultant and DeST to simulate. Combine thermal environment and energy consumption to measure and simulate indoor thermal comfort and energy consumption, provide a new design method for the research of university and college building energy consumption. At the same time, the passive strategy has far-reaching significance for the design and transformation of university buildings.
