Abstract

An increased utilization of renewable energy sources in the heat and electricity generation is one of priority tasks of the Slovak Republic to boost the use of domestic energy potential and thus to decrease the Slovakia’s dependence on imported fossil fuels. Heat pumps and photovoltaics offer the most energy-efficient way to provide heating and cooling in many applications, as they can use renewable heat sources in our surroundings. The experimental workplace of our Faculty “Economic Research Centre for Renewable Energy Sources and Distribution systems” was founded with the purpose of investigating possibilities to reduce the energetic costs of buildings tied to economy. The realized project of the Centre creates real environment for effective implementation research of technologies in laboratory and operative conditions: technologies of co-generative elements, heat pumps, photovoltaics elements, thermal capillaries, and technologies in field of measurement and regulation. The result is the design with possibility to repeat it on other similar applications as well as the utilization of experience and determination of economical expedience of researched technologies implementation. In the contemporary phase of the research we evaluate of operative behavior of the zero-energy building, interaction with building constructions and study of inner climate parameters and overall results for central heat supply system.
