The National Taiwan University of Science and Technology will attend the FOR ARCH 2017 fair and present the heat insulation solar glass.
The glass is very unique in the world due to it can generate solar power to supply all the energy consumption from cooling and heating system and still remain some power to feed back into grid. There is no possibility for any other Low-e glass in the world to reach this target.
The reflection of the heat insulation and reflection film can enhance the solar power generation and heat insulation simultaneously to gain more renewable energy and reduce more energy consumption from cooling and heating system. According to the test result of three real glass houses site testing at National Taiwan University of Science and Technology the Heat Insulation Solar Glass (HISG) house performed outstanding energy efficiency while compared with normal and low-e glass house.
Based on a continuous site testing from Oct. 2014 to June 2015 of 3m x 3m x 3m glass houses, the HISG house gained 685 kWh during this period. It can supplied all the heating and cooling consumption of 317 kWh during this period and remained 368 kWh feeding back into grid. Contrarily, the ordinary glass house consumed 587 kWh on cooling and heating system. The energy efficiency during this period could be 955 kWh due to the contribution from HISG.
The HISG has been proved to possess the highest capacity of energy efficiency for zero energy buildings in the world. The HISG could be applied on the vertical window or skylight for zero energy buildings. According to a computer simulation on the energy saving of a 26m x 26 m skylight on a 4 m high building in London and Abu Dhabi, the HISG can save 173,993 kWh and 256,512 kWh and decrease CO2 of 121,795 and 179,558 kg respectively while compared with normal glass.
The HISG is very unique in the world for zero energy buildings in the future."
