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).

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, Health & Comfort and Learning & Education. CLIMA 2022 will have its EYE ON 2030.
