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.

IKEA stores begin to switch over to solar heating and cooling

Submitted by Baerbel Epp on February 13, 2018
Ikea SingaporeIKEA, one of the world´s biggest home furnishing retailers, has demonstrated a strong, long-term commitment to climate protection. By 2020, the company intends to generate as much energy from renewables as it consumes in day-to-day operations. While most of the electricity is now generated from renewable sources, IKEA’s store managers have not lost sight of the heating part of the equation. Two locations, one in Singapore (see photo) and one in the Russian Omsk region, have recently announced the completion of new solar heating and cooling installations.

CBENS to discuss solar heat for industry

Submitted by Baerbel Epp on February 12, 2018
CBENS 2018Brazil’s solar energy association ABENS has invited about 500 experts to the solar energy conference CBENS taking place from 17 to 20 April 2018 in Gramado. This year’s event, held in the south of the country, offers a round-table discussion about solar heat for industrial processes, or SHIP for short, to raise awareness among technicians, researchers and future professionals of a technology that many in Brazil know little about.
 

State-of-the-art collector production in Uzbekistan

Submitted by Baerbel Epp on February 9, 2018
gazeta.uzLast November, Uzbek-based Artel Group gave a tour of its new collector and tank production facility. It houses the manufacturing lines for selectively coated and laser-welded collectors traded under the brand name Royal. Stainless steel tanks insulated with polyurethane foam and holding between 300 and 1,000 litres complement the business’s product portfolio. Turkish manufacturer Solimpeks has been advising the company on design matters since 2016.

SHC industry roadmap for Australia

Submitted by Baerbel Epp on February 8, 2018
Despite Australia’s high levels of solar irradiation and rising energy costs, its solar heating and cooling market has been in decline each year since 2010. The newly installed glazed and unglazed collector area went from a peak of 1.14 million m2 in 2009 to 544,670 m2 in 2016 – less than half of what it used to be. Reversing the downward spiral is the aim of an industry roadmap, titled Solar Heating and Cooling in Australia´s Built Environment, which was commissioned by ARENA, the Australian Renewable Energy Agency, and is currently under review. During an internal workshop in Abu Dhabi last November, Australian-based consultancy Coolgaia discussed the findings from the roadmap with solar cooling experts working on Task 53 of the IEA Solar Heating and Cooling Programme (see photo).

Solar to replace coal in Polish district heating networks

Submitted by Baerbel Epp on February 7, 2018
NFOŚiGWZbigniew Kamieński, adviser to the president of NFOŚiGW’s board, has recently made some encouraging statements. During the conference Use of renewable energy sources and seasonal heat storage in district heating in Warsaw on 17 January, he said that the proposal of a new subsidy programme for renewable district heating deserved attention and implementation. The conference with nearly 130 attendees was organised jointly by NFOŚiGW, the National Fund for Environmental Protection and Water Management, and IEO, the Institute for Renewable Energy, and was supported by the SDHp2m project

Lebanon´s success in driving down prices

Submitted by Baerbel Epp on February 1, 2018
Lebanon learning curveThe Lebanese solar thermal market has made great strides in bringing down the cost of solar water heating. Between 2010 and 2016, average system prices decreased by 43 %, from USD 1,880 to USD 1,313. This is one of the key findings presented by Tony Gebrayel, Energy Engineer at LCEC, the Lebanese Center for Energy Conservation, during the Beirut Energy Forum in September 2017 (see the attached document). The reduction was achieved by stable sales of between 50,000 and 60,000 m² of collector area per year.

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.

Solar-heated hotels in MENA region

Submitted by Baerbel Epp on January 29, 2018
GIZ Hotel BroschureSolar thermal can easily provide cheap, secure and clean heat to drive growth in the tourism sector. But what about optimal system sizes and applications? A new brochure has been trying to find answers to this question. Titled Solar PV & Thermal Applications for Hotel Sector, it has been created jointly by the German Agency for International Cooperation and the Egyptian Regional Center for Renewable Energy and Energy Efficiency as part of a project called Re-Activate: Promoting Employment through Renewable Energy and Energy Efficiency in the MENA Region.
