Webinar Cover 2023-09-19On the global level, buildings account for around 40% of the primary energy consumption and approximately 25% of greenhouse gas emissions. In Europe, buildings are responsible for 40% of the energy consumption and 36% of the CO2 emissions. Additionally, building construction materials embody large amounts of energy embody large amounts of energy.

IEA SHC Task 66 on Solar Energy Buildings is focused on developing economic and ecologically feasible solar energy supply concepts with high solar fractions for new and existing buildings and communities. The targeted solar thermal and solar electrical fractions depend significantly on the climate zone.

For moderate climate conditions as in central Europe, northern China, and northern USA, the solar fractions to achieve are:

  • At least 85% of the heat demand.
  • 100% of the cooling demand.
  • At least 60% of the electricity demand for households and e-mobility.

IEA SHC Task 66 work covers single-family buildings, multi-story residential buildings and building blocks, and both new buildings and the comprehensive refurbishment of existing buildings.

This webinar will provide an overview of the work of SHC Task 66 on Solar Energy Buildings and present the most important results achieved so far.

Q/A Session: The 90-minute webinar will include a 30-minute 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 Programme and hosted by ISES, the International Solar Energy Society.
