Energy Savings and Photovoltaic Power Generation
Low-E
Photovoltaic Glass
for Buildings
Often the total area on the vertical sides of a building are far greater than the area of rooftops. This area should be used for energy generation without sacrificing the aesthetics and design freedom of the building envelope. Kaneka’s enabling photovoltaic technologies integrate energy generation into building materials and their applications.
Building Integrated Photovoltaics (BIPV) has the capability to drive these values in the building envelope.

IGU & PV Energy Savings - New Construction
IGU & PV Energy Savings Retrofit
Disclaimer: Calculated values are based on numerical simulations performed by Institut für Bauklimatik Dresden. For the simulation BIM HVACTool Version 1.8, EnergyPlus Version 8 and NANDRAD Version 1.4 were used. Climate was defined by data from DWD and IWEC. The simulated building has a volume of 11,640m³. 40% of the facade surface is covered by windows.
