The energy renovation project of three courthouses in Slovenia – in Celje, Murska Sobota and Slovenj Gradec – has been successfully completed. This Slovenian Ministry of Justice project was conducted within the framework of a public-private partnership (PPP) and carried out by a consortium of GGE and Petrol.
The goal of the project was to raise energy efficiency and save money on annual costs associated with heating and lighting systems in these buildings, says GEE on its website.
The GGE – Petrol consortium was selected for this job by public tender issued by the Ministry of Justice in 2016.
As part of the retrofitting project, the boiler rooms were renovated and improved, natural gas was replaced the extra light fuel oil, thermostatic valves with hydraulic balance were installed, thermal insulating materials were used, and building furniture was replaced.
Lighting systems also went through a renovation, with introduction of more energy efficient lamps, and energy management and monitoring systems were installed in all three facilities for better control over energy consumption.
According to the GGE statement, the renovated courthouses will now benefit from the following annual savings:
Murska Sobota: heat 164 MWh and electricity 53 kWh,
Celje: heat 242 MWh and electricity 84 kWh,
Slovenj Gradec: heat 70 MWh and electricity 40 kWh.
In a Public private partnerships between GGE and a public partner, GGE provides financing and implements the project, as well as maintenance services for the duration of the contract.
GGE recoups its investment gradually, with the public partner immediately benefiting from savings. Once the contract expires, the public partner benefits from the full amount of savings.
This is one of many public-private partnerships GGE has implemented in the region. Another project in Slovenia is the largest energy efficiency PPP in the region signed with the City of Ljubljana, for retrofit of 49 municipal buildings. GEE carries on that one also in a consortium with Petrol, for the energy retrofit of 49 municipal buildings.
In the region, there is also the public private partnership for heat energy delivery with the City of Pirot. Public lighting renovation PPPs carried out by GGE include the cities of Kruševac and Petrovac na Mlavi in Serbia, along with municipalities Ada and Žabalj, and the Istrian city of Novigrad in Croatia.
