A great deal of interest in photovoltaics (PV) integration into buildings has been developed by heat insulation solar glass (HISG) due to the advantages claimed of HISG (in terms of energy saving in the cold and hot seasons, enhance power generation and self-cleaning, protection from external noise and wind loads). This study compares energy consumption of heating and of cooling in three houses of normal glass (Ordinary house), Low-E glass (Ordinary solar house) and HISG house. Results show that the energy-saving efficiency of the HISG house has achieved respective 70.68 and 56.09% for cooling; about 23.53 and 10.34% for heating as compared to those of the Ordinary house and Low-E house. The energy consumption for heating and cooling of the HISG house has significantly reduced with energy efficiency ~19.59–37.07% at outdoor temperature above 30oC compared to that of the Ordinary house. The results in this study also offer a low-cost route to the application of HISG modules on buildings with high energy-saving efficiency, it is able to be used for monitoring progression of the greenhouse gas reduction, as well as evaluating their energy efficiency on buildings in the green buildings at the current and future.
