D5.2 Report on Improvement Contributions of the LTH/HTC System

This report provides description of the thermal comfort effects of the proposed low-temperature heating (LTH) and high-temperature cooling (HTC) systems in the pilot sites of Aran Islands and Sant Cugat. The pilot sites, the studied heating and cooling systems and the used modelling software are described. Suggested LTH and HTC systems are simulated and the results are compared with a baseline scenario. The results are presented and discussed. The simulations show that in the case of Aran Islands, the suggested hybrid heating system could potentially improve the thermal comfort of the occupants significantly while reducing the required supply temperature. In the case of Sant
Cugat, the results show that installing either of the studied types of cooling systems would clearly improve the thermal comfort of the occupants, with the radiant cooling system slightly outperforming an all-air system. Real-life performance evaluations will be included after the studied system being installed in pilots in the next version of the deliverable.
