Crowdfunding the Heat Changers campaign

Submitted by Baerbel Epp on July 2, 2018
Photos: Heat ChangersThe German Solar Heating Initiative has put together a crowdfunding project to fund a consumer campaign called Heat Changers. Its initiators, Marisol Oropeza and Stefan Abrecht (first and second image from top left), have already brought some well-known supporters on board, including Markus Elsässer, Founder and Managing Director of Solar Promotion and organiser of the Intersolar Europe (bottom left), and Australian Ken Guthrie, formerly chair of the IEA Solar Heating and Cooling Programme (top right). The funding deadline for the EUR 35,000 project on kickstarter.com is 19 July 2018. The money is intended to be used for a six-month solar heat promotion campaign via social media, a website and other online tools.

Daniel Mugnier Is New IEA SHC Chairman

Submitted by Baerbel Epp on June 27, 2018
The new chair of the IEA Solar Heating and Cooling Programme, also known as IEA SHC, will be Daniel Mugnier, a leading expert in solar cooling. Mugnier, who heads the R&D department at French-based Tecsol, was elected during an executive committee meeting in Stockholm on 21 June and will hold the position for two years. He will replace Australian Ken Guthrie, who has chaired IEA SHC since 2014.

Rising demand for solar heat in large buildings and industry

Submitted by Baerbel Epp on June 6, 2018
SHW 1By the end of 2017, the market for solar heating and cooling had grown by 472 GWth, which again made it the largest for solar energy in the world. The one for photovoltaic systems gained 402 GWp to become the second-largest, and 5 GWel was enough for concentrating solar power to rank third, according to the latest Solar Heat Worldwide report. The report also highlights the rising use of megawatt-class solar heating and cooling solutions for large public and residential buildings, as well as factories. It was launched at the end of May by the IEA Solar Heating and Cooling Programme (IEA SHC). Lead author is the Austrian research institute AEE INTEC.

This was one of the main messages of the International Workshop on the Status of PVT Systems, organised by Fraunhofer ISE on 16 May 2018 in Freiburg. The event, held as part of IEA SHC Task 60, Application of PVT Collectors and New Solutions in HVAC Systems, featured 15 speakers, who updated 63 attendees working in industry and science on the progress made with PVT products and research.

On-site collector testing: new standard in development

Submitted by Baerbel Epp on May 17, 2018
Photo: Riccardo BattistiOnce a large solar field is set up at its designated location, what tests can be conducted to show that it performs as expected? Soon, the IEA Solar Heating & Cooling Programme may have an answer to this question, as it is working on internationalising Denmark’s testing procedure. No decision has been made on whether the procedure will become part of a full-fledged standard or be turned into a technical specification.

Building-integrated solar envelopes: barriers to deployment

Submitted by Baerbel Epp on May 2, 2018
Solar FacadeActive and passive solar systems integrated into building envelopes are key to combatting climate change. However, there are many barriers which confine current solutions to the demonstration stage and prevent them from going mainstream. To increase the size of the market, researchers have examined these barriers as part of Task 56, Building Integrated Solar Envelope Systems for HVAC and Lighting, under the auspices of the IEA Solar Heating & Cooling Programme. Their report will not be available until September 2018, but this article contains a summary of the main conclusions.

IEA SHC Webinar: Cost reduction potential above 30 %

Submitted by Baerbel Epp on April 5, 2018
Chart: AventaThe key takeaway from an IEA SHC Solar Academy webinar held on 14 March 2018: There is still much room for cost cuts along the entire solar thermal value chain. The webinar was organised jointly by the IEA Solar Heating & Cooling Programme’s Task 54 and the International Solar Energy Society.

Solar district heating on the Roof of the World

Submitted by Baerbel Epp on February 27, 2018
Photo: Task 55A contract to set up a solar district heating network in Langkazi county in Tibet has been awarded to Arcon-Sunmark Large-Scale Solar Systems. The Chinese-Danish joint venture signed an agreement with the local government of the autonomous region of Tibet. The system should provide solar district heating for 82,600 m² of floor area and meet 90 % of the yearly space heating demand in Langkazi, the town sharing its name with the county. The system, planned to be set up by November, will consist of a 22,000 m² collector field, 15,000 m³ of pit storage and a 3-MW electric boiler. The sponsor of the pilot project is China’s central government.

Solar cooling increases annual solar fraction

Submitted by Baerbel Epp on February 24, 2018
Task 53 1Solar cooling could be an effective way to increase the annual solar fraction of domestic hot water production and prevent the solar system from overheating in summer. Under the aegis of the IEA Solar Heating & Cooling Programme, researchers from Task 53, New Generation Solar Cooling & Heating Systems, have written a new book, titled The Solar Cooling Design Guide: Case Studies of Successful Solar Air Conditioning Design. It includes a detailed case study of two buildings containing offices and flats in Montpellier, France. The on-site 240 m² flat plate collector system powers a 35-kW absorption chiller to achieve a 70 % solar fraction in annual hot water production (see photo). Between November and March, the system continues to provide around 40 % of the heating energy to meet hot water demand.
