The project signed between HEP ESCO and the Karlovac County was implemented on the basis of two contracts, covering electromechanical and structural measures of energy efficiency. In total, the Project encompasses about 20 energy efficiency measures in eight schools, the value of equipment and works being about 8.2 million kuna.
The electromechanical measures of energy efficiency included modernization work on lighting and heating systems in four schools. Modern fluorescent lamps with electronic dimmers were installed, whereby interior lighting has been improved and energy consumption reduced.
Besides lighting improvement, electricity-related measures included installation of reactive energy compensator. Heating modernization included installation of automatic heating controls responding to external temperature, thermostatic valves for room temperature control and replacement of a worn hot water boiler with a new high-efficiency boiler. All these measures have resulted in reduced energy consumption for heating, contributing to energy efficiency.
Regarding structural reconstruction, in four schools obsolete external carpentry was replaced with multi-chamber PVC carpentry and low-heat loss glazing. Thermal insulation of the façade of one school was also performed. These structural measures significantly reduce the level of heat energy required for heating, contributing directly to savings.
After all works were carried out and HEP ESCO Project completed, the schools were left with modern equipment and improved heating and lighting systems which are less costly to use and maintain.
