Application of Heat Insulation Solar Glass for Glass Buildings

Abstract

To enhance electrical energy production and improve heat insulation of photovoltaic modules (original solar glass module), a simple method for installation and generation of heat insulation solar glass (HISG) modules from traditional transparent PV modules (original solar glass modules) using heat insulation materials, improving functions such as power generation, heat insulation, energy saving and greenhouse gas reducing. Interest in photovoltaics (PV) integration into buildings, as well as heat insulation solar glass (HISG) be used as curtain walls on the buildings has been developed, where the HISG curtain walls play the role of building exterior components as an integral part of buildings as well as of producing electricity and providing functions such as heat insulation and selfcleaning. Two experimental houses used normal glass and HISG as curtain walls on the Ordinary house and the HISG house were constructed in this study. Results show that the illuminative penetration on HISG curtain was quietly high with efficiency of 32%, block UV-rays to 100%, low solar radiation 40% as compared to normal glass curtain wall (~97%), greatly enhanced indoor lighting ~29.4% and high heat insulation efficiency ~28.2% as compared to normal glass curtain wall on the Ordinary house. In addition, the energy-saving efficiency of the HISG house for heating and cooling were greatly improved respective to ~40% and 48% for comparisons to the Ordinary house, and the power generation of HISG curtain wall on the HISG house was achieved 2.63 kWh of electricity per day. Our work offers a low-cost route to the application of HISG modules 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.
