According to the company website, Singaporean investment holding company Rowsley had spent USD 5 million on the design of a selective coating for these metal plates. Professor He Tao from the China Academy of Building Research (middle of the photo), visited Sanqiaoneng’s coating plant in late January.

Europe’s first-ever renewable heating and cooling target

Submitted by Baerbel Epp on June 26, 2018
Renewable Energy Directive for 2030After night-long negotiations, the European Parliament and Council have reached an agreement on the Renewable Energy Directive for 2030. At long last, discussions that started in November 2016 came to a close in the early morning of 14 June. The new regulatory framework stipulates that a 32 % renewable energy target is to be achieved by the EU in 2030. “This is a substantial increase compared to the 27 % originally proposed by the European Commission,” said Pedro Dias, Secretary General of Solar Heat Europe/ESTIF. “Moreover, the Commission can now take corrective action if this overall target is not met.”

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.

EU Funding for Solutions to Decarbonise Heating and Cooling Market

Submitted by Baerbel Epp on November 19, 2017
Horizon 2020A search for ‘solar thermal’ in a recently published 195-page document titled Secure, Clean and Efficient Energy will not return encouraging results (see the attached document). The publication by the Horizon 2020 Work Programme 2018-2020 shows only 6 entries in total. “Solar thermal is definitely not a priority of the new programme,” said Daniel Mugnier, Head of R&D at French engineering services company Tecsol. “And even if the European Solar Thermal Technology & Innovation Platform were to try to promote several hot topics, there’s only one call [LC-SC3-RES-7-2019 on solar process heat] dedicated to the technology.”
 

SHC 2017: Largest experts’ meeting on integrated solar heating and cooling

Submitted by Baerbel Epp on November 8, 2017
SHC2017_1500 experts from more than 50 countries attended the 5th International Conference on Solar Heating and Cooling (SHC) in Abu Dhabi, UAE, from 30 October to 2 November 2017. It was the first time that this biennial conference by the IEA’s Solar Heating and Cooling Programme had been organised jointly with the Solar World Congress by the International Solar Energy Society (ISES). The new partnership resulted in 2017’s largest experts’ meeting on integrated SHC solutions for buildings, industry, cities, regions and utilities, and in over 300 presentations.

Belo Horizonte – Brazil´s Solar Capital

Submitted by Baerbel Epp on October 25, 2017
Belo HorizonteBelo Horizonte, a municipality about 600 km north of Sao Paulo in the state of Minas Gerais, is also known as the solar capital of Brazil. Not only does it have a population of about 2.5 million, but solar water heater installations on many of its high-rise multifamily buildings. The photo shows one example, a block of flats for the wealthy middle class. The roof is completely covered in solar water heaters, which meet around half of the annual hot water requirements. This article will present the main drivers of an exciting market development in Latin America: a university research group specialised in solar heating and cooling, committed system planners, strong manufacturers and a pro-solar state utility.

China: Solar Process Heat and Space Heating and Cooling Rack Up Market Shares

Submitted by Baerbel Epp on April 19, 2017
CSTIFChina’s shift away from residential towards commercial solar thermal applications continues: The collector area of newly installed solar water heaters in single-family buildings declined by 26 % in 2016, whereas the ‘engineering segment’ remained stable last year (see the table below). This segment is comprised of all non-domestic hot water applications, such as space heating and cooling as well as applications in industry and agriculture. Overall, its share in the newly installed collector area went from 61 to 68 %. All figures were taken from the Report on the State of China's Solar Thermal Industry (July to December 2016), a document drafted by Dezhou-based consultancy Sun’s Vision on behalf of CSTIF, the Chinese Solar Thermal Industry Federation. CSTIF has presented this report – which also includes several development strategies – to the National Energy Board. 
 

Nicaragua: Soft Loan to Fund EUR 4 Million Project

Submitted by Baerbel Epp on October 14, 2016
Hospital ManaguaThere is now nothing in the way of constructing an impressive solar heating and cooling installation in Nicaragua. At the end of September, the last signatures were placed under the contract documents for a 4,450 m² collector field which will supply air conditioning and warm water to the Hospital Militar Escuela Dr. Alejandro Dávila Bolaños in Managua (see photo), the capital city of the central American nation. “Installation work will start in January 2017, and commissioning is planned for the second quarter of next year,” was how Christian Holter, Managing Director of S.O.L.I.D, outlined the ambitious plan. The Austrian turnkey system supplier had been struggling for over three years to receive financing for the 4 million EUR project in form of a soft loan, a financing instrument for developing countries.

SOLTRAIN: 2,150 Technicians Trained and 187 Demonstration Systems Installed in SADC Region

Submitted by Baerbel Epp on March 1, 2016
SOLTRAIN ConferenceThe Southern African Solar Thermal Training and Demonstration Initiative (SOLTRAIN) presented the project’s remarkable progress since 2009 during a conference in Midrand, South Africa, on 11 February 2016. “Between 2009 and 2015, about 2,150 people have been trained in 80 courses, and nearly 187 solar thermal systems ranging from 2 to 250 m² collector area per system have been installed in the five target countries South Africa, Namibia, Lesotho, Mozambique and Zimbabwe,” Project Coordinator Werner Weiss, Managing Director of Austrian institute AEE INTEC, summed up the results. The photo shows the presentation of Dr Thembakazi Mali, Senior Manager Clean Energy Solutions at the South African National Energy Development Institute (SANEDI) on 11 February. The one-day conference was attended by 63 stakeholders from the SADC region.
