TASK 66: Solar Energy Buildings

Integrated solar energy supply concepts for climate-neutral buildings and communities for the "City of the Future”

IEA Solar Heating & Cooling Technology Collaboration Programme

The Solar Heating and Cooling Technology Collaboration Programme (SHC TCP) was established in 1977, one of the first programmes of the International Energy Agency, to promote the use of all aspects of solar thermal energy. The SHC TCP's work is unique in that it is accomplished through the international collaborative effort of experts from member countries and the European Union.

The benefits of this approach are:

  • accelerates the pace of technology development
  • promotes standardization
  • enhances national R&D programmes
  • permits national specialization
  • saves time and money

What's New
  • SBE21 conference spotlights historic NZEBs - The SBE21 Heritage conference in mid-April involved a deep exchange of ideas between researchers, architects and practitioners about how to reduce the energy consumption of historic buildings while retaining their aesthetic features and cultural significance.

  • How to design an 85 % solar-heated and 100 % solar air-conditioned house - During an online meeting from 1 to 2 July, the IEA Solar Heating and Cooling programme will launch a new global research platform called Task 66 Solar Energy Buildings. The researchers participating in the new task intend to develop and popularise a building standard focused on solar energy as the main energy source for heating, cooling and electricity generation.

  • Survey: Multiple-benefits and priorities in Solar Neighborhoods - What are the priorities in the planning of your neighborhoods and cities? You are invited to contribute to our research on Solar Neighborhoods. (Posted: 2021-04-26)
  • Solar-heated multi-family buildings gain popularity in Germany - Many new largely solar-heated houses in Germany are multi-family buildings, and their number is growing, according to Sonnenhaus-Institut (Solar House Institute), an alliance of about 300 architects, planners, building companies and system integrators that specialise in the design or construction of houses where sunlight provides at least 50 % of the heat and, in some cases, electricity a year. (Posted: 2021-04-24)
  • Solar houses: above 95 % solar fraction is possible - Between 2014 and 2019, the Austrian Climate and Energy Fund supported the construction of over 100 solar-heated houses, 19 of which were monitored by the Austrian Institute AEE INTEC following completion. (Posted: 2021-04-24)

  • END of Task 60 - Task 60 has officially ended on Dec 31, 2020.
  • SBE keynote speakers announced - Get inspired by SBE21 Heritage Keynote Speakers Dr. Ege Yildirim and Prof. Harald Garrecht.
  • Strategies to promote solar envelopes - In the last four years, the multidisciplinary IEA SHC Task 56 research group worked intensively on strategies to increase the market penetration of solar envelope systems. The group has found that prefabrication, a customisable appearance and an interdisciplinary planning process can provide component manufacturers with significant opportunities for growth.
  • Using solar energy to recover acids and metals from wastewater - An IEA SHC research group led by Dr Joachim Koschikowski, of Fraunhofer ISE, has created a matrix depicting thermal separation methods for industrial wastewater treatment and resource recovery. As part of Task 62, Solar Energy in Industrial Water and Wastewater Management, launched by the IEA SHC programme in October 2018, the group took a closer look at which industries could benefit from using solar heat to reclaim acid and metals from wastewater streams.
  • SHC Technology Position Paper: PVT Collectors and Systems - The quest to decarbonize society's electrical and thermal systems has never been more urgent.  In this Technology Position Paper, experts of IEA SHC Task 60 on PVT Systems layout how to support the development of PV/Solar Thermal (or PVT) collectors and systems.

Solar Heat Integrations in Industrial Processes

Solar Heat for Industrial Processes (SHIP) is at the early stages of development but is considered to have enormous potential for solar thermal applications. The industrial sector accounts for approximately 30% of the total energy consumption  in OECD countries. And, the major share of the energy needed in this sector is used for heating and cooling buildings and production processes at temperatures from ambient up to approximately 350°C. This is a temperature range that can be addressed with solar thermal technologies. -- View PDF
