The Study On The Appropriate Technology Of Green Office Building In Cold Area

In recent years, with the system of green evaluation in China is increasingly perfect, scientific research evaluation agencies have been established, the state and the introduction of policies to encourage local and green building research project to carry out a comprehensive, China’s green building industry has been rapid development. At the end of the two quarter of 2013,6 years a total of top 978 green building label project, the total construction area of 105,000,000 square meters. Both the construction of 40,000,000,000 square meters of green building in China, accounting for 0.25%. Among them, the green public building 459, Green Office identified 211, accounting for about half of the total public building.With the rapid development of China’s green building industry, many green building projects have been completed and started operating while the number of green building labeling China increased year by year, but the result is not ideal for green building. First of all, the implementation of green building technology is poor, a lot of technology only stay in the design stage not put into operation. Logo certification programs are more concentrated in the green building design stage, green office building operation identifies the project only account for 8.5% of the total green office building. Secondly, the poor effect of green technology is put into operation, can not achieve the expected benefits.The cause of the failure of green technology has two main points:first, the designer in the green building design stage, the technology for analysis and economy, not suitable for project their own characteristics, suitable climatic conditions, suitable for site requirements of the technical scheme of the cost budget and the investment recovery. Blind reference evaluation standard for green building, green building technology added, the architectural design and green building requirements, combined with mechanical stiffly, resulting in some of the green building is not green. The rapid development of the green building industry which hinder the healthy. Second, in the building after the operation, the lack of professional property management team on the green technology further supervision and maintenance. Therefore, the green building should be increased in view of the different regional climate characteristics in terms of research, study on appropriate technology type refinement architecture.The research object is set to the office building in cold area. Taking into account the main office building as an important part of public buildings in China, generally belongs to the high energy consumption buildings, and along with the increasing of large projects of the government office, its social influence is also growing. Secondly, the cold area as one of the five regions in China, with the cold and long winter, summer is hot and the precipitation is relatively concentrated. Because of this area in winter, summer climate comfort is low, most of the air-conditioning, indoor heating system to meet the indoor comfort requirements, resulting in higher energy consumption of office building in cold region. Third, a good operation effect of green office building in cold region, in green building operation identification to obtain office project, number of run ID cold area accounts for 38.9%, is located in the five major climatic zones for the first time. Therefore, in the region to promote green office building has to saving energy and resources, on the other hand, in the promotion of the concept of green building to play a good exemplary role.This research method is different from the traditional theory research method, which belongs to a feedback model, namely the feasibility of green technology running through the actual test results, then the theory to supplement and correction. Mainly from the cold region of China has won the GBL projects selected 20 representative office building as a case study, the implementation of the three part of the situation, operation situation, operation efficiency of investigation, statistics, analysis of green technology used in these projects, summarizes the common technology of office building in cold area and difficulty of implementation technology, and technology problems in operation.In the existing office building green technology research foundation, combined with the characteristics of climate in cold area and green building practical results, summarize the office building for green technology used in cold regions. In this paper, the green technology mainly includes two parts of green building design and the appropriate technology selection.1. Green building design refers to design the building to meet the current conditions of their green, namely the maximum use of favorable environment (wind, light, landscape), avoiding the environment unfavorable site (noise, dust). This part summarizes the professional green building (site design, architectural design, HVAC design) design principles;2. Part of the choice of appropriate technology appropriate technology for office building in cold area (simulation technology, energy-saving technologies, water-saving technology, intelligent technology) were summarized using conditions, implementation, economic benefits, office building in order to guide the different scale, different investment expected for technology selection.In the Chinese CNOOC building project for the appropriate application of technology in the practice of green office building in cold area with comprehensive instructions. Introduction to project design, technology selection and operation efficiency, in order to provide a reference model for the green office building design in cold area.
