A Study of Technical and Economic Analysis to Energy-saving Glass of Construction in Hot Summer and Cold Winter Zone

摘要

In hot summer and cold winter zone, engineers and designers are always plagued by the rational use of energy-saving glass combining with practical engineering. Scientific selection of energy-saving glass has important theoretical and engineering significance for building energy saving. In this study, glass comprehensive index was established, technical and economic factors of glass were considered altogether. The comprehensive indexes of different energy-saving glasses were calculated and the evaluation analyses of energy-saving glasses were done. For the first time, research results show that mid-hollow Low-E glass has maximum energy efficiency under the present technical and economic conditions and vacuum glass has wide application prospect in the future. The conclusions of the study are in good agreement with engineering practice.
