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.
General State Hospital of Nikala Agios Panteleimon, Athens, Greece (NHOSP)
NHOSP is the second largest hospital in the area of Balkans (largest in Greece) operating multiple intensive care and special care units. Totally 56 windows and balcony doors will be replaced with Switch2Save energy smart IGU/windows in four representative clinics of NHOSP of south orientation, where indoor conditions are of outmost importance, from premature babies to elderly adults.
The ambition is to:
- Demonstrate renovation integration of a significant number (56) into an operational environment without modifying the building structure within < 2 weeks per unit (closing time) and without disturbing operation in adjacent clinics
- Determine and demonstrate (TRL7) improved energy saving and thermal energy storage capacity in an operational environment in a Mediterranean climate through 12-month continuous energy monitoring before and after energy smart window installation.
- Demonstrate that adaptive glazing can play a pivotal role not only in energy saving but also in improving healthcare
Vasakronan owned Rental Office Building, Uppsala, Sweden (VAS)
VAS is an operational office building with rental offices currently being used by two companies (Ramboll Engineering Office, and Briab Fire Consultants). The building was assembled in the year 2000. It is a six story high building with garage in the basement story. It is a medium heavy concrete building, with a rather large share of window glass. The building was classified LEED Gold in 2004. Switch2Save will replace glass facades (total surface area > 200 m²). A minor modification of the sash / frames for the IGUs will be implemented to hold triple pane IGUs. In contrast to that, the automatically controlled window blinds will be removed. The installation will be performed during full operation of the building.
The ambition is to:
- Demonstrate minimum disturbance by replacement of glass facades with novel energy smart solutions during full operation of the building
- Determine and demonstrate improved energy saving and thermal energy storage capacity in an operational environment in a Northern Europe climate through 12-month continuous energy monitoring before and after energy smart window installation.
