In 2016, air-conditioning accounted for nearly 20% of the total electricity demand in buildings worldwide and is growing faster than any other energy consumption in buildings. The main share of the projected growth in energy use for space cooling comes from emerging economies and will more than triple by 2050 to 6,000 TWh/a. Therefore, the IEA SHC Task 65 “Solar Cooling for the Sunbelt Regions”, started in July 2020, is focusing on innovations for affordable, safe, and reliable Solar Cooling systems for the Sunbelt regions. The innovation is the adaptation of existing concepts/technologies to the Sunbelt regions using solar energy, either solar thermal or solar PV. Solar cooling will therefore play an important role in the decarbonization of the cooling sector using natural refrigerants, e.g. with hybrid system solutions of all kinds coming onto the market.

The webinar gives an overview of the market and technology development (Prof. Dr. Uli Jakob, JER/Green Chiller) and reports first insights from the analysis of boundary conditions and potentials for solar cooling systems within the Sunbelt region based on geographical data (Richard Gurtner, ZAE Bayern) as well as the assessment and benchmarking of solar cooling systems in general (Dr. Daniel Neyer, Neyer Brainworks).

The webinar moderated by Bärbel Epp of the German consultancy Solrico.
