The REHVA HVAC World Congress CLIMA is the leading international scientific congress in the fields of heating, ventilation, and air conditioning (HVAC).

 After the great success of the 2022 edition, organised by the Dutch association TVVL, the baton now passes to AiCARR for the organisation of CLIMA 2025: the 15th REHVA HVAC World Congress, which will be held in Milan, Italy, from June 4th to 6th, 2025.

The theme of this Italian edition is 'Decarbonized, healthy, and energy-conscious buildings in future climates', a topic that highlights the fundamental importance of the HVAC sector in all its aspects.

 In this perspective, CLIMA 2025 will offer professionals, academics, and companies in the HVAC sector a unique opportunity for international discussion about these 'hot' subjects.
