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
• Learning & Education.

CLIMA 2022 will have its EYE ON 2030.

Energy

CLIMA 2022 considers beside the Energy Efficiency First principle the Clean Energy Transition of the built environment of vital importance. The development of high-performing building services systems that use heat, cold and electricity from renewable resources is accelerating, creating a need for flexibility, energy storage and inter-building energy exchanges.

Digitization

CLIMA 2022 considers digital solutions that encourage the energy transition in the built environment as a very important theme. Solutions of the digital building transformation are expected in the areas of (predictive) digital twinning, data-driven smart buildings, data management, and continuous commissioning.

Health & comfort

The achievement of health and comfort of people in the built environment, whether at home, at work, at school, or enjoying free time, is a complex subject that involves physics, behaviour, physiology, energy conservation, climate change, architecture, engineering and technology. 

Circularity

As a result of a growing population worldwide and the need for comfortable and healthy indoor environments, a massive building challenge lies ahead with the development of new building projects as well as the need to upgrade the existing building stock.

Learning & education

The European Union set ambitious targets for the green energy transition in the built environment.  To deliver the transition to an energy-efficient, circular, digitized and healthy built environment, we need the urgent upscale of skills and knowledge and the wide dissemination of technical innovations, proven knowledge and approaches.
