“BREEAM certification is a requisite to keep our properties competitive and sustainable whilst ensuring the durability of the tenant in the premises.”
- Cooling production is provided through two geothermal heat pumps which dispatch into the building through a cooled water loop.
- The heating system relies on convector supplied with grid electricity controlled through the BMS.
- Fresh air rate of over 36m3/h/occ is provided through air conditioning centrals (CTA) into the offices, connected with CO2 detectors.
- Electricity generated with 400 m² solar panels and 2 urban wind turbines.
- Solar thermal panels save energy for the hot water system connected to restaurants.
- Replacement of the two air to air heat installed on terrace by two geothermal heat pumps.
- Refrigerant detection system on the geothermal heat pumps technical local.
- Additional thermal isolation on the roof.
- 400 m² photovoltaic panels.
- 60 m² solar thermal panels for hot water production.
- 2 urban wind turbines.
- Green roofing with sebum helping rainwater run-off and thermal isolation
- Rainwater recycling system for irrigation and toilets
