On October 16 2019, Switch2Save project was officially kicked-off at the meeting of consortium partners in Dresden, Germany. Coordinated by Fraunhofer FEP and with AMIRES participation, the project goal is to improve the availability and affordability of electrochromic (EC) and thermochromic (TC) smart glass technologies.
The Switch2Save consortium includes leading universities, research institutes and industries from six EU countries. Within the next four years, the partners will collectively develop a combination of EC and TC cells – with optimized maximum energy saving potential – based on a switchable total energy transmittance (g-value). They will scale the manufacturing technologies for increased availability and cost effectiveness, assess the performance of the innovative insulating glass units (IGU), and demonstrate the heating and cooling energy saving potential and the lighting comfort in two operational buildings in Greece and Sweden.
The Switch2Save EC and TC modules are based on nanoscaled thin film stacks that are applied to plastic webs or ultra-thin glass films by using large area vacuum and atmospheric pressure deposition techniques. The modules have a specific weight of less than one kg per square meter – much less than even a single glass pane in a window. They are easily integrated into IGUs by a lamination step to allow window and glass façade manufacturing with well-established processes – a key requirement for acceptance of the novel technology by construction companies. The integration of wireless switching and standard interfaces directly into the building automation systems will satisfy the needs of building owners and provide maximum energy saving when in operation.
Switch2Save will demonstrate the potential in two representative buildings – Greece’s second largest hospital in Athens and an operational office building in Uppsala, Sweden. The Switch2Save consortium will replace 50 windows and 200 m² glass façade area with the smart glass solution and will perform a full “before-after” comparison of the energy demand for a one-year cycle in both buildings. The findings will accelerate the widespread implementation of energy smart glass and significantly contribute to the goal of a CO2-neutral building stock in the EU before 2050.
