Viikki Environment House - Smart Demand Response System & Renewable Energy Storage

Viikki Environment House is a high-performance office building in Helsinki. Part of the energy consumed in the building is produced on-site: the solar panels placed on the façade and roof cover 572m² and produce 20% of the energy consumption along with four wind turbines. The energy needed for heating water and interior spaces is supplied by Helsinki’s district heating network. The cooling is supplied through a cost free borehole water system that consists of 25 boreholes each 250 m deep and making 95% of the cooling energy renewable.
 A building automation system has already been implemented to couple the need of energy and heat and electricity production. The storage is connected to other building energy loads to enable better optimisation and provide the nearby public e-car charger with solar energy.
Viikki Environment House has been equipped with smart heating control and demand response along with modifications to the existing building control management on heating and electricity optimisation.
