ThermCo

ThermCo evaluates low-energy cooling concepts all-over Europe using a standardised method based on existing
monitoring data from best practice examples, provides design guidelines for typical building concepts in the
European climate zones for architects and HVAC-engineers and collects the knowledge available. The proposed
approach is applied to eight demonstration projects in different climatic zones of Europe.

The aim of ThermCo was to evaluate low-energy cooling concepts all-over Europe using a standardised method based on existing monitoring data from best practice examples, to provide design guidelines for typical building concepts in the European climate zones for architects and HVAC-engineers and to collect the knowledge available. The proposed approach was applied to eight demonstration projects in different climatic zones of Europe.

High performance buildings have shown that it is possible to go clearly beyond the energy requirements of existing legislation and obtaining good thermal comfort. However, there is still a strong uncertainty in day-to-day practice due to the lack of legislative regulations for mixed-mode buildings which are neither only naturally ventilated nor fully air-conditioned, but use a mix of different low-energy cooling techniques. Based on the findings from monitoring campaigns (long-term measurements in combination with field studies on thermal comfort), simulation studies, and a comprehensive review on existing standards and guidelines, the main outcome of the ThermCo project is a REHVA Guidebook which will act as a commonly accessible knowledge pool for passive and low-energy cooling techniques. The RHEVA Guidebook on Low-Energy Cooling and Thermal Comfort (expected date of publication: May 2010) will support HVAC planners in reducing the cooling energy demand, improving the indoor environment and designing more cost-effective building concepts.
