Abstract [en]

This paper presents the modeling results of combining low temperature heating (ventilation radiator) with ventilation energy-demand savings. Investigations on operational energy and thermal comfort are in focus.

IDA ICE is employed to investigate the thermal performance and energy usage. The results show that low temperature heating can reduce mean air temperature fluctuations in the selected archetype. When combining low temperature heating with ventilation and air-tightness renovations, the thermal performance of the heating system can be largely improved to an acceptable level. The retrofitting strategy can save 41 % of heating energy demand and 27 % of total primary energy.
