The Federation of European HVAC Associations (founded in 1963) is an umbrella organisation joining European associations in the area of building engineering services, representing more than 100,000 HVAC engineers and technicians from 27 European countries, and with supporter companies representing the HVAC industry. Its mission is to promote the latest technologies, research, knowledge exchange and capacity building and to support EU policy development. In hybrid GEOTABS, REHVA is supporting WP7 - Communication & dissemination activities promoting the concept. 

REHVA is in charge of task 7.2 on the dissemination of the project results towards building services professionals via its EU-wide network and communication channels (REHVA Journal, REHVA website, LinkedIn REHVA Energy Group,, CLIMA World Congress, etc.), as well as towards EU level stakeholders, policy makers and standardisation bodies. REHVA is also promoting the market uptake and exploitation of the developed Plug in GT technology by promoting the technology in industry fairs and professional conferences across Europe. It will update its technical guidebook on GEOTABS based on the project results and disseminate training materials developed for HVAC professionals via the PROF/TRAC Training and Qualification Platform (
