Research On Energy Conservation Reconstructions Of Existing Government Office Buildings In Wuhan City

In this paper, the government office buildings in Wuhan are the object of study. First of all, we do some research to find the climatic characteristics of Wuhan City and the characteristics of energy consumption of government office buildings. On the base, we analyze the strengths and weaknesses of energy-saving technologies and energy-saving materials to find suitable energy-saving methods, which can be used for external walls, windows, shading, ventilation, roof and lighting equipment and so on.Based on the above methods, the author take a government office building in Hankou as an example to find out optimized methods by using computer simulation. Energy simulation software DeST-C exploited by Tsinghua University and the International commerce software Airpak for HVAC are the main tools to simulate. By the simulation of a variety of energy-saving methods ,we can find the best way to reconstruct the building .In particular, the author highlights the benefits of energy saving habits(people take the initiative to reduce electricity consumption ) which often neglected by people and the pay more attention to zero-investment ecological method such as natural ventilation (in summer morning and evening ) . Finally, we can find a method which can reach the requirement of Public buildings energy-saving design standards, need less money, and be friendly with the Ecological environment.At the end of the paper, in order to promote the public buildings energy conservation reconstruction in Wuhan city ( a large research and construction project) to be carried out smoothly ,the author also give some advices to help the supervision and regulation work of energy conservation reconstruction in Wuhan City.
