THE WAY TO LIMIT EMISSIONS - THE ONLY PASSIVE REGIONAL GOVERNMENT BUILDING IN POLAND
About this good practice
The West Pomeranian region has built its new headquarters in a way that combines attractive architecture and state-of-the-art automation with ecology. This so-called 'passive building' is the only regional government headquarters in Poland to be built using passive construction methods. Thanks to the use of several innovative solutions, the building has an extremely low energy consumption. This is confirmed by the BREEAM certificates. The building operates a BMS for efficient energy management.
An educational trail has also been developed to show how energy can be saved using today's technology and to raise awareness among residents and tourists visiting the building.
Two heat pumps have been installed in the boiler room, with a combined heating capacity of 225 kW and a cooling capacity of 180 kW. Space heating is provided by fan coil units. The air handling units have COMBI exchangers. The buildings also draw energy from the sun. Photovoltaic panels (102 modules in total) with a total maximum capacity of 39.69 kWp have been installed on the roofs of the buildings, and all premises are equipped with devices and systems to reduce electricity consumption. Energy-saving and efficient LED lighting has been used.
In the passive building on Mazowiecka Street, the annual heat gains significantly exceed the annual heat demand, so some of the heat and cold can be transferred to the building on Piłsudskiego Street. This provides a thermal balance for both buildings
Resources needed
The investment cost more than PLN 200 million (EUR 48 million). 76% of this was provided by European Funds.
Evidence of success
- Lower operating costs for energy management;
- Building uses eight times less energy than a standard building;
- Promotion of innovative solutions, including heating and cooling systems;
- Maximum use of energy from natural resources;
- Off-grid operation capability;
- Increased comfort for employees and interveners;
- Increased independence from fossil fuels;
- Ensured better indoor air quality through the possibility of CO2 and humidity control;
- Ensured low-temperature fluctuations.
Potential for learning or transfer
The solutions used in passive building can be replicated in regions and cities where existing fossil fuel heating systems and more environmentally friendly solutions are desired. The aim would then be to reduce air pollution and energy consumption. Directive 2010/31/L of the European Parliament and of the Council of 19 May 2010 states, among other things, that public administration buildings should in principle be near-zero energy buildings. So there is no doubt that the example of the headquarters of the West Pomeranian Region shows the way forward in terms of changing the public administration buildings, but it is also a way of raising public awareness about the construction of low-temperature district heating networks.
