There are many benefits of building construction with prefabricated thermo active ceilings technology, and the most highlighted are: short lead time, ease of installation, low price, lack of taking up space in a room and additionally the possibility of working in heating and/or cooling mode. An analysis was carried out to illustrate the factors that influence the thermal output of a ceiling heating system in residential buildings located in 5 climate zones in Poland and 2 in Ukraine. The thermal loads were determined for the entire building, designed in accordance with the regulations in force in each country, for the flats and particular rooms (considering the heat exchange between the flats according to PN-EN 12831:2006). An average heating medium temperature of 34°C was assumed. The results were compared with the achievable heating capacity of the ceiling system, which results from the difference between the heating medium temperature and the indoor room temperature. It was investigated that the system achieves the calculated output in all climate zones in Poland, while it will not be sufficient in Ukraine. This is due to both less stringent building thermal protection regulations and different indoor design temperature values, resulting in a higher average temperature in the flat. When analysed on a room-by-room basis, it became apparent that in all considered locations there were rooms for which the heating capacity was insufficient. In the climate zones I to IV in Poland, the problem concerns only bathrooms, where in this case quite often the surface heating can be combined with a supplementary electric radiator. In the V climate zone in Poland and both in Ukraine, the solution to the power shortage under design conditions may be: building construction according to a higher energy standard, increasing the supply temperature (with the limitation of maximum ceiling surface temperature to 35°C for living spaces) or using additional heating elements not only in bathrooms. A novel part of the article discusses calculated power shortages in relation to climate change and the external design temperatures suggested by sources other than the standard.

Warunki klimatyczne w istotny sposób wpływają na zapotrzebowanie na energię, na potrzeby ogrzewania. W artykule przeanalizowano wpływ lokalizacji budynku mieszkalnego na terenie Polski, na jego wskaźniki energetyczne. W szczególności oceniono zapotrzebowanie na moc grzewczą, na energię końcową i energię pierwotną paliw nieodnawialnych. Na podstawie uzyskanych wyników obliczeń określono również wartości współczynnika ostrości klimatu i porównano z zalecanymi do opracowywania audytu efektywności energetycznej.

The climatic conditions have a significant impact on the energy demand for the purpose of heating. In the following paper the location impact of the residential building in Poland and its energy indicators have been analyzed. Particularly the demand for heating power, the final energy and non-renewable primary energy fuels have been estimated. On the base of the results of calculations the harsh climate values have been determined and they have also been compared with the recommended for development the audit of energy efficiency.
