Cím:	Effects of building refurbishment on the operative temperature and ACH / Kalmár Ferenc, Kalmár Tünde, Varga Edit, Csáki Imre, Jenei Tünde
Dátum:	2009
Megjegyzések:	In residential buildings and block of flats built until 1980, because of the poor thermal insulation of the external building elements, the energy consumption is high in order to assure the thermal comfort needs of the occupants. The air tightness of the closing elements is also low so the infiltration is high enough to avoid the capillary condensation. The mean radiant temperature of the building elements is slightly low because of the poor insulation. To obtain a certain operative temperature value the indoor air temperature has to be kept at a higher value. In both cases appears supplementary energy consumption. In this paper two side effects of additional thermal insulation are analysed from energy point of view. On one hand to avoid capillary condensation lower ACH is needed, therefore energy savings up to 7% are obtained. On the other hand because of the higher mean radiant temperature to obtain the same operative temperature lower air temperature should be provided, so the energy savings can reach even 20%.
