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.

Daylight and electric lighting: new research initiative

Submitted by Baerbel Epp on February 14, 2018
Task 61The IEA Solar Heating & Cooling Programme has approved Task 61, a new research initiative concentrating on integrated daylight and electric lighting solutions. The task will tackle unresolved issues and challenges of a growing market which meets 19 % of the total electricity demand around the world. It will launch with a 3-day workshop from 28 February to 2 March 2018 in Lund, Sweden. Experts with a background in R&D or manufacturing are welcome to join the initiative.

District heating shows lower total socio-economic cost in future energy system

Submitted by Baerbel Epp on January 31, 2018
Costs for ST 1What would the economic impact on a future energy system be if one were to unlock the full solar thermal potential in Austria, Denmark, Germany and Italy? According to a study conducted by Aalborg University as part of the IEA SHC Task 52 research project Solar Heat and Energy Economics in Urban Environments, exploiting the maximum potential will result in significant cost reductions if solar heat is supplied not individually but by district heating. The graph shows small changes of between -0.1 % and +0.2 % in total socio-economic cost both in the District Heating scenario (expansion of district heating grids) and the Heat Savings one (retrofits reduce heat demand in buildings) when the maximum solar thermal potential is realised by using either decentralised solutions or district heating to supply heat to consumers. The key factor influencing the outcome is the cost of solar thermal systems.

French PVT market is picking up

Submitted by Baerbel Epp on December 22, 2017
DualsunThe IEA’s Solar Heating and Cooling Programme will create its own international research platform on PVT systems in January 2018. Researchers and industry representatives from 13 countries so far will then start evaluating new PVT systems for HVAC solutions. This IEA SHC task, which is planned to run until the end of 2020, is being announced at a time when the PVT market in several European countries, such as France and Switzerland, is picking up speed. Experts with an R&D or manufacturing background are welcome to join the platform (see the contact details at the end of this news article).

How to approach green construction in the tropical zone

Submitted by Baerbel Epp on December 11, 2017
Dr Gao BCA SingaporeWhile nearly zero energy projects in Europe focus on reducing heat demand, green buildings in tropical Singapore require lower cooling loads. To study and discuss methods to meet cooling needs, construction and energy experts from all around the world met in Singapore in late October for a two-day workshop organised by the Building & Construction Authority Singapore (BCA) and the IEA’s Buildings and Communities Programme (EBC). The aim of the Future Buildings Forum (FBF) 2017 was an agreement on strategic R&D priorities for Transforming Cities in Hot and Humid Climates Towards More Efficient and Sustainable Energy Use.

SHC / SWC 2017: Twelve Experts Highlight Success Stories on Tape

Submitted by Baerbel Epp on December 4, 2017
videosFrom 30 October to 2 November 2017, the SHC 2017 and the SWC 2017 in Abu Dhabi brought together 500 researchers, industry specialists and other experts on solar heating and cooling. The 12 video interviews that recorded at the joint conference outlined trends in today's global solar heating and cooling sector and highlighted policy fields where urgent action is required. The videos were financed by the IEA Solar Heating and Cooling Programme and the European Copper Association. See the complete playlist.

IEA SHC Task 54: Solar Thermal Cost Reductions

Submitted by Baerbel Epp on November 26, 2017
Linz workshop Task 54The objective of IEA SHC Task 54 is to reduce the purchase price of solar thermal systems by up to 40 % across the entire value chain. To achieve this, the project partners have been evaluating technical and non-technical cost-saving potential, with low-cost materials, such as polymers, and production technologies bound to play an important role. At an early October workshop in Linz, Austria, about 50 project partners and guests discussed cost reductions made possible by new distribution channels, digital solutions and systems thinking approaches.

IEA Paper: How to Decarbonise the Industrial Sector

Submitted by Baerbel Epp on November 22, 2017
Cédric PhilibertThe industrial sector is the hardest to decarbonise. “Stakeholders are in fierce competition, so to adapt any source that is even slightly more expensive than the fossil fuels they are used to is difficult,” Cédric Philibert, Senior Analyst in the IEA Renewable Energy Division, said during the panel discussion The Road to 100% Renewable Energy at the joint SHC and SWC 2017 conference in Abu Dhabi in early November. He presented key findings from his most recent Insight Paper, Renewable Energy for Industry, which takes a closer look at cement manufacturing, iron- and steelmaking and chemical production (see the attached document).
