Regional adaptability of typical energy efficiency technology in GB 50189-2015 Design standard for energy efficiency of public buildings

The heat transfer coefficient of opaque structures and the window to wall ratio are the important aspects that influence the energy saving of building envelope. Performance coefficient of water chiller is the key point for energy saving of the system. Taking the public building model database as the research objects, evaluates the overall performance of public building in each climate zone by the final calculating result according to the weighting method of distribution feature. By the single factor analysis method, calculates the energy saving effect of the same energy conservation measures in different climate zones. A quantitative analysis of energy saving measures can directly show the necessity for the application of the energy saving measures.
