The object of this research was to investigate of the energy performance of a national chicken slaughterhouse in order to achieve condenser heat utilization generated by the operation of the existing, refrigerant systems. The paper focuses also for the technical realization of condenser heat utilization by concept plans and payback time calculations. The utilizing heat of a cooling circle's condenser is a quite quickly returnable investment. The time of payback is around 330 days by heat utilizing for hot water preheating and also air heating.

“…The EU Directive 2010/31/EU requires buildings, or parts of buildings, to meet a minimum energy performance or be subject to a retrofit or refurbishment [4][5][6]. These requirements may be met by renovating a building's envelope and HVAC systems [7][8][9][10][11]. The stability of indoor air parameters is also a very important factor, essential for such institutions, schools, hospitals and also museums.…”

In this research the technical designing of energy efficient heating system with vertical-borehole heat pumps for institutional buildings was performed. The local government would like to change the old gas boiler-based heat producing system to up-to-date, environmental friendly equipment with the financial support of the European Union. The payback time was calculated and environmental calculations were achieved with carbon dioxide saving by various conditions that were also achieved during the research project. The results show that the heat pump system also provides a significant reduction of environmental load, in addition to significant energy savings. The amount of calculated savings justifies the environmental friendliness of heat pump systems.
