Energy-Saving Behavior of Windows for Public Buildings in Cold Region

The design of windows and glazing curtains is the key point in energy-saving design procedure. According to the investigation and analysis, energy losing through windows is in the majority of overall energy consumption. The types and behaviors of energy saving windows are discussed in brief. According to the specification of Design Standard for Energy Efficiency of Public Building of China, the thermal insulation performances of exterior windows are analyzed theoretically. On the basis of climate characters of cold region in china and requirements of the criterion for public architectures energy-saving design，the proper types for the northern region of china are put forward, and therefore provide references for architectural designers.
