The first public-private partnership in Slovenia for the supply of heat and cooling in the Town Hall of City Municipality of Kranj.
Due to improvements in the Town Hall of City Municipality of Kranj convenience of the users of the building in winter and summer was increased. Energy demand for heating and cooling was reduced with cogeneration of heat and electricity and also by 30 kWp photovoltaic power plant placed on the roof of the building. Average annual heat demand of previous years amounted to 826 MWh. A comparison was made for the heating season 2012/13 where was taken into account use of heat measured up to and including the month of February 2013. For the remaining months comparison has been based on calculated approximation of previous years. The use of heat at the end of the heating season is around 590 MWh, which represents approximately 29% reduced heat consumption. Installations were renovated and the central control system and soft measures as education of employees were also introduced. As result of all these measures the need for heating was reduced.
Public-private partnership investment volume of 1.7 mio EUR includes investments in:
- gas boiler, power of 635 kW,
- central cooling, 250 kW,
- CHP system - 80 kW,
- renovation of mechanical installations,
- Air Conditioning of meeting halls,
- photo voltaic power plant of 30 kWp.
Evidence of success
Successful implementation of investment resulted in 236 MWh or 29% reduction in heat consumption and improved working conditions (air condition) for employees.
Potential for learning or transfer
For the project of public-private partnership the changes in national law were needed.
