The IEA Solar Heating and Cooling Programme has published a Call for Nominations for its 2017 Solar Award. Until 1 May 2017, administrators of successful SHC support programmes or policies can be nominated for the award, which will be presented at the International Conference on Solar Heating and Cooling for Buildings and Industry taking place in Abu Dhabi from 29 October to 2 November. “Recipients will have demonstrated substantial achievement and measurable market impact from a programme / policy measure implemented in the last 5 to 10 years to support solar heating and cooling,” the call announcement reads. Nominations can be submitted online.
Two large industry events in China over the last months have shown that there is great demand for discussion regarding the transformation of the domestic solar heating and cooling market. The Green Business Forum attracted around 1,000 solar thermal stakeholders to Dezhou in Shandong province from 22 to 25 September, and several hundred industry representatives took part in the annual assembly of the Chinese Solar Thermal Industry Federation (CSTIF) from 7 to 9 December in Kunming, Yunnan province (see photo). According to the latest CSTIF figures, the solar thermal market experienced a sharp 9 % decline last year from 43.5 million m² to 39.5 million m² (30.5 to 27.7 GWth), which reduced it to 60 % of the size it had had in the peak year of 2013.
Masdar Institute of Science and Technology will host the key solar heating and cooling conference this year in Abu Dhabi from 29 October to 2 November. Two major organizations in the solar arena joined forces to offer a conference with a wide range of solar heating and cooling topics: IEA Solar Heating and Cooling Programme (IEA SHC) and the International Solar Energy Society (ISES). One registration fee will get you into both events – International Conference on Solar Heating and Cooling for Buildings and Industry (SHC 2017) and ISES Solar World Congress (SWC 2017). Joint plenary sessions will be followed by parallel sessions, which are arranged separately by IEA SHC or ISES, and jointly organised sessions on selected topics like solar buildings. The Call for Papers for both conferences is open until 24 March 2017.
The 191 solar process heat projects which have made it into the online database add up to an installed capacity of 0.11 GWth (0.159 million m²), which is only a small fraction of the potential estimated for this type of application. To quantify the technology’s global opportunities, the researchers from the now-completed four-year Task 49 / IV, Solar Heat Integration in Industrial Processes, analysed the results of several national studies which had tried to determine the potential of solar process heat while considering restrictions such as temperature range and the space available for the systems (see the chart on the left). “For Europe, where mainly non-concentrating collectors had been investigated, the percentage of technical potential for solar process heat related to the total industrial heat demand is around 3 to 4 %,” was the conclusion by the authors of the attached report Potential studies on solar process heat worldwide.
After seven years, the IEA Solar Heating and Cooling Programme (IEA SHC) is planning to launch another international research cooperation on PVT technology. PVT includes panels which combine photovoltaics and solar thermal into one unit either as glazed or unglazed systems. The first and only task on PVT systems was completed in June 2010. The new one, entitled Application of PVT Collectors and New Solutions with PVT Systems, is in the definition phase. It is expected to start in July 2017 and run for 3.5 years. Interested researchers and industry representatives have been invited to attend a two-day workshop at ETH university in Zurich, Switzerland, from 16 March (1 p.m.) to 17 March (12 a.m.) in order to discuss crucial aspects and the structure of the global initiative.

The recent approval of Working Rules means that the Global Solar Certification Network (GSCN) can now accept membership applications. The reuse of test and inspection reports in different certification schemes will be possible at the beginning of 2017. The GSCN was developed in Task 43 of the IEA Solar Heating and Cooling Programme to facilitate the cross-border trade of high-quality solar thermal products. The world map shows all the certification schemes which are already on their way into the GSCN – and more are said to follow soon. GSCN industry members can use a collector test report or a production inspection report from one of these schemes to apply for a certificate in another part of the world which is also part of GSCN. The procedure saves manufacturers time and money by removing the need for collector retesting or a second site inspection.
Whether investors put their money into large-scale concentrating solar heat and power systems, solar district heating plants or photovoltaic fields, they need to be able to rely on data sets to include the uncertainty and variability of input information. Financial institutions do like to know in what way these factors can impact revenue flows in financing, so researchers of IEA SHC Task 46, Solar Resource Assessment and Forecasting, have spent several years analysing various approaches to the topic. The flow chart of the financing model shows that solar resource data is essential to a proper assessment of the average power or heat generation per year as well as the range of variability over several years. SHC Task 46 is a five-year collaborative effort (2011-2016) with support from the IEA SolarPaces Programme (Task V) and the IEA Photovoltaic Power Systems Programme (Task 14).
From 11 to 14 October, more than 300 experts in solar energy met in Palma de Mallorca for the EuroSun 2016 conference. Organised by the International Solar Energy Society (ISES) in cooperation with the University of the Balearic Islands (UIB), the conference is attended mainly by scientists and industry stakeholders from the solar heating and cooling sector. But for the first time, speakers also included well-known specialists from the photovoltaics sector. Two panel discussions illustrated the wide range of opinions on solar heat and solar electricity market development and the technologies' competitors. The photo shows Professor Eicke Weber (middle), newly elected Vice President of ISES and Director of the Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE) based in Freiburg, Germany, and two of the three conference chairs: Professor Wolfgang Streicher (left) from the University of Innsbruck, Austria, and Professor Víctor Martínez Moll (right) from the UIB.
The summer school called City in Transition (Stadt im Wandel) ended with a public presentation of the project designs from four student groups on Monday, 26 September, in Berlin, Germany (see photo). During the previous week, students from different fields and German universities had developed a master plan for solar-optimised buildings in an area of Berlin’s Adlershof district. ”We educated students on how to combine town planning and solar energy usage,” explained Tanja Siems, one of the organisers of the summer school and Head of the Institute of Urban Design & Studies, Faculty of Architecture and Civil Engineering of the University of Wuppertal, Germany. Several experts from the IEA Solar Heating and Cooling programme’s Task 51, Solar Energy in Urban Planning, had supported the summer school as tutors or evaluated the final presentations.
LED technology has greatly changed the face of the lighting market: In just a few years, lighting systems have become twice as efficient and half as expensive. These changes have resulted in a large but often untapped cost- and energy-saving potential in commercial buildings. The research in Task 50 of the IEA Solar Heating and Cooling programme, Advanced Lighting Solutions for Retrofitting Buildings, has shown that the lighting industry is increasingly exploring opportunities for the use of contracting instead of leasing solutions to convince customers of retrofits. According to Marc Fontoynont, Professor at the Department of Energy Performance at Aalborg University, Denmark, and subtask leader of Market and Policies, there is a growing number of specialised companies which offer contracting models for lighting solutions, such as Austrian manufacturer Zumtobel has done with its contracting plan Now! (see chart). All in all, these contracting solutions are less complex than the ones for heat.
