IEA SHC Solar Academy: Task 65 Solar Cooling for the Sunbelt Regions - I

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 will give 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 (Tobias Schmetzer, ZAE Bayern) as well as the assessment and benchmarking of solar cooling systems in general (Dr. Daniel Neyer, Neyer Brainworks).

The webinar will be moderated by Bärbel Epp of of the German consultancy solrico.


Q/A Session: The 90-minute webinar will include a 30 minutes Q/A session and a recording of the webinar will be available online afterward. The webinar is organized by the Solar Academy of the IEA Solar Heating and Cooling Program and hosted by ISES, the International Solar Energy Society.


Special announcement - Webinar re-run on 27 October 2022 at 6 AM GMT/UTC

ISES and the IEA SHC Solar Academy are happy to announce that this webinar will be broadcasted again on 27 October 2022 at 6 AM GMT/UTC to accommodate our global audience, especially from Australia and Asia. The broadcast webinar will then be followed by a live Q/A with the webinar speakers.

Uli Jakob

Uli Jakob is Director of dr. jakob energy research GmbH & Co. KG (JER). He has more than twenty years of industrial and scientific professional experience, particularly in the product development and commercialization of renewable and energy-efficient technologies. His areas of specialization are building physics, renewable energies and climate engineering, with a particular focus on innovative energy concepts and energy efficiency in industry and urban districts. He holds a PhD in Applied Thermodynamics from De Montfort University Leicester, U.K. and an engineering degree in building physics from the Stuttgart University of Applied Sciences. In May 2020 he received an honorary professorship from the Stuttgart University of Applied Sciences.

Before founding JER, Uli worked as CTO/ Director at the international system supplier SolarNext AG and as Managing Director/ Research Assistant at the Competence Center for Sustainable Energy Technology ( in Stuttgart. Since September 2012 he has also been Managing Director of the Green Chiller Association for Sorption Cooling e.V. based in Berlin and was appointed Operating Agent/ Task Manager of the IEA SHC Tasks 65 on Solar Cooling for Sunbelt Regions (2020-2024) in June 2020.

Uli will introduce task 65.

Tobias Schmetzer

Tobias Schmetzer is the GIS and tooling engineer in the project "SunBeltChiller – a Solar thermal energy system for cooling and process heat in the sunbelt region" at the Bavarian Center for AppliedEnergy Research, ZAE Bayern in Garching, Germany. Tobias Schmetzer studied computer engineering at the Technical University of Ilmenau and has been working in the fields of GIS systems, heat distribution grids and chillers/heat pumps at ZAE Bayern since 2021. Within the IEA SHC Task65, Tobias works together with Richard Gurtner on Subtask A1: Climatic conditions & applications.

Tobias will present an analysis of boundary conditions and potentials for solar cooling systems within the sunbelt region based on geographical data.

Daniel Neyer

DI Dr.techn. Daniel Neyer is Founder and Managing Director at neyer brainworks, a certified consulting office for renewable energy, building services and energy-efficient buildings. In 2021, he co-founded a social business – TWIGA Sun Fruits GmbH, which is providing turnkey solar heating/cooling solutions for the agro-food sector. Besides, he is a senior researcher at the Unit for Energy Efficient Buildings at the University of Innsbruck. He is an Engineer holding a master's degree in Eco Energy Engineering, a master's degree in Domotronic, and a PhD in technical sciences and gathered more than 15 years of R&D and professional experience. He is involved in several national and international projects and is an Austrian expert in the IEA SHC Tasks. His main fields of activities are numerical simulations in HVAC’s and buildings, component and system development and optimization as well as assessment and benchmarking of renewable heating and cooling systems. Currently, he is Subtask C leader of the IEA SHC Task 65.


Daniel will present an assessment and benchmarking of solar cooling systems.
