Study On Energy-saving Of Industrial Buildings

Along with the development of economic and the acceleration of urbanization, the construction is in rapid development. World energy is shortage, but building energy is rising. Now, people pay more and more attention to energy saving of building and do a lot of work for it. National and local laws and regulations of the energy conservation have been issued. For example," the design standard of public building energy efficiency "," the design standard of residential building energy saving ", and so on. The technical standard provide powerful technical support for building energy saving. The design research of industrial building energy saving start the80Era and China would build the statistics system about transportation industry and industrial energy. The national bureau of statistics also regularly released the investigation result about energy consumption, although this work has been doing, but the research of widely system is still relatively slowly. So far, only individual industry standard of energy saving and the energy-saving criteria are qualitative requirements, and the maneuverability is not strong. Currently, there does not have a complete national standard of industrial building energy-saving.First, this paper analyzes the characteristics of industrial energy consumption. Also, it describes the main characteristics and application field of DeST energy simulation software. The article take printing company in Shanxi province as an example, analyses the impact of building enclosure structure on building energy consumption by the DeST-c. It simulates different kinds of envelope of annual energy consumption, and proposed some appropriate energy-saving measures. We use DeST establishment building energy simulation software for load calculation model, use dynamic simulation method for simulation of large factory hot and cold all year round the total load, cold and heat load hourly, and Annual cooling and heating load index. By changing the parameters of the method to comparative simulation analysis, we can get loads of different values,. Therefore, we can analyse the factors affecting the whole building energy consumption and compare the results. Through the energy simulation and analysis, we can have some discussion on energy saving of industrial building.
