R10 – Switch2Save

Switch2Save A leap forward in smart windows and glass façades for highly efficient energy management using novel switching technologies.

In modern architecture, large-area glazing is a continuing trend because of its appearance and design variety. Large southwards-oriented windows help to reduce the energy demand for heating in winter. However, large-area glazing may significantly increase the energy demand for cooling and air-conditioning in hot summers. 

Smart Glass Solutions – such as electrochromic (EC) and thermochromic (TC) windows and glass façades – control the radiation energy transfer with the “touch of a button” and thus can drastically reduce the energy demands for heating and air conditioning of large buildings. In addition, they allow superior indoor lighting comfort in contrast to conventional mechanical window blinds. On October 1, 2019, the EU-funded initiative “Switch2Save” was launched to improve the availability and affordability of EC and TC smart glass technologies. The consortium of ten partners from research and industry will demonstrate the energy saving potential of smart glass solutions in two fully-operational buildings.

Climate change is a topic now on everyone’s lips and climate targets are being discussed at all levels. Solutions such as the use of natural resources for energy generation and energy recovery in existing cycles are currently of high research interest. One building block for a sustainable future is the EU Energy Performance of Buildings Directive that targets a full zero-emission building stock all over Europe before 2050.
