Energy saving design method study on university existing buildings in cold climate zone

Based on numerous universities of various types it is identified that they have become a major energy consumer. This study takes existing public buildings of universities in cold climate zones as the object and starts with the investigation into the current situation and characteristics of energy consumption by public buildings of one typical university in Xi'an to systematically analyze the characteristics of existing buildings, test the thermal environments in summer and winter, and obtain first-hand data. Besides, the principles and design methods suitable for the existing public buildings' energy-saving, the transformation of universities are discussed with a view to find out its key problems and establish a corresponding energy-saving technology system. With respect to the application technologies, flexible technology combination and application is achieved, aiming at different characteristics of existing building energy consumption and the input of transformation funds, and energy-saving technology clusters at different levels are formed to practically implement the transformation.
