The building uses all forms of renewable energy sources available in Central Poland: solar energy (both for heating and electricity generation), biomass, wind, and underground heat.
The load-bearing elements of the building are:
▪ foundation: monolithic reinforced concrete slab 30cm made of tight concrete on periporous blocks 35cm thick, with perimeter thermal insulation
▪ external construction walls made of silicate blocks insulated with a 35 cm layer of mineral wool.
▪ internal construction walls made of silicate blocks (class 20 MPa)
▪ ceiling made of prefabricated, prestressed concrete slabs, 20 cm high, with rims on the edges;
▪ partition walls made of silicate blocks
The building façade includes aluminium windows and external doors, meeting the requirements for the frame and glazing U <0.80 W / m2K, with solar radiation energy transmittance for glazing g> 50%. The building is equipped with mechanical supply and exhaust ventilation based on heat recovery units. Ventilation also acts as air heating. There are two groups of rooms in the building: research laboratories and office/training rooms. Separate air handling units were designed for each group of rooms.
The building is equipped with three heat sources:
▪ a ground-air heat exchanger – is responsible for initial heating of the ventilation air, and in summer it is used for passive cooling of the building
▪ three reversible air-to-air heat pumps – proper heating or cooling of the ventilation air
▪ a biomass boiler with a capacity of 22 kW – peak source, used for heating and domestic hot water preparation.
The domestic hot water preparation system is a bivalent system. The main sources are solar collectors: vacuum and flat collectors (4 pcs), operating in separate circuits, periodically supported by a biomass boiler.
Electricity to power the building comes from the power grid, a micro-wind turbine (500W), and an on-grid photovoltaic installation with a capacity of 30 kW. The building is integrated with a BMS and an electric vehicle charging station.
