CLIMA 2022 EYE ON 2030
we go on in hybrid form

The REHVA World Congress CLIMA is the leading international scientific congress in the field of heating, ventilation and air conditioning (HVAC). The congress is organised every 3 years by one of the member associations of REHVA. CLIMA 2022 will be organised by TVVL, the Dutch Society for Building Services in collaboration with both Delft University of Technology and Eindhoven University of Technology.

From now to 2030 the world of HVAC will change radically. Fuelled by irreversible influences, the current demands on climate installations will change completely. To meet global climate goals and pursue the EU Green Deal, the regulatory environment on building performance, decarbonisation and the energy transition will change in 2022 within the ‘EU Fit for 55 package’, while the Renovation wave strategy aims at the deep energy renovation of up to 35 million buildings by 2030.

CLIMA 2022 will focus on 5 themes related to this massive transformation that is on the horizon: Energy, Circularity, Digitization and Health & Comfort. Everybody will agree that these themes will have a huge impact. But how will they evolve from now till 2030? Which insights will we have with regards to the themes? And how do these themes relate to each other? Will they reinforce or delay each other? And how does the impact of climate installations relate to the building process and other influences? What education and learning is needed? With these questions in mind, CLIMA 2022 will have its EYE ON 2030.

Important: CLIMA takes place the 22nd – 25th of May 2022.
