Lightweight switchable smart solutions for energy saving large windows and glass façades
Start date: 01.10.2019
Duration: 48 months
Coordinator: Fraunhofer Institute for Organic Electronics
Budget: 6.32 M€
The EU-funded Switch2save project proposes new materials that reduce energy demands in buildings with large glass areas. Their method involves the integration of transparent energy-smart materials with switchable total energy transmission values (g-value) to control the entrance of solar radiation. Switch2save has a unique performance, reduces manufacturing costs and increases opportunities for shadow solutions. Two prototypes will be tested in two buildings with large glass façade areas, a hospital in Greece and an office building in Sweden.
Switch2save targets active management of radiation energy transfer through glass-based building envelopes by integrating transparent energy smart materials with switchable total energy transmission values (g-value). Such materials are electro-chromic (EC) or thermo-chromic (TC) systems. Intelligent switching of those allows significant reduction of both heating energy demand in winter and cooling energy demand in summer. Switch2save’s unique and lightweight combined EC and TC smart insulating glass unit will be a breakthrough in performance (plus 20%); low-cost potential (minus 33% manufacturing cost) and increased design opportunities compared to state-of-the-art smart shading solutions.
