The project is part of the 2014-2015 Programme of Energy Renovation of Public Sector Buildings, adopted by the Croatian Government in 2013. This Programme has generated 57 public procurement procedures for the provision of EPC, 21 signed contracts for 68 buildings (total floor area: 225.000 m2 ), and € 125 million of total investment, for 70 million kWh of expected energy savings.

 

Basic settings and characteristics of the program: the ESP provides energy services to improve the energy performance of building. It prepares project documents, carries out the energy renovation of the building (construction works, installation of equipment and materials), and monitors and maintains all building elements and installed equipment. ESP invests and takes technical and economic risk. The Client ensures payment of compensation to ESP during the contract period. Payment of services is based on verifiable savings (service charge should be less than the savings).

 

Replication/transfer/upscale: replicability is ensured by the Programme of Energy Renovation of Public Sector Buildings for the period 2014-2015.

 

Measurement, reporting & verification: throughout the contract duration, the Energy Service Provider (ESP) shall monitor and control savings.
