Energy efficiency funding in Bosnia and Herzegovina

Submitted by Baerbel Epp on May 11, 2018
Map: lonelyplanet.comThe Jugoslav Wars of the 1990s slowed down the rate of energy-related retrofits in the residential and public sectors of Bosnia and Herzegovina. Recently, however, the country has seen some improvement in the amount of funding available for clean heating technologies, such as solar thermal, biomass boilers and heat pumps. In early April, the European Bank for Reconstruction and Development, or EBRD for short, provided MKF Partner, a Bosnian microfinance institution, with EUR 5 million for low-interest loans and grants to make residential buildings more energy-efficient. It was the second time the EBRD had allocated funding to financial institutions in the country. Last November, EUR 17 million went to three Bosnian banks, as part of the EBRD’s Green Economy Financing Facility.

Solar showers for displaced people and refugees

Submitted by Baerbel Epp on April 20, 2018
Logo UNHCRThe UN Refugee Agency has begun ordering solar water heaters to improve the sanitary conditions in Ugandan refugee camps. The news ties in neatly with the first conference on Energy for Displaced People: A Global Plan of Action for Sustainable Energy Solutions in Situations of Displacement, an event which took place in mid-January in Berlin, Germany, and was attended by more than 100 delegates. The participants agreed to “lay the groundwork for the first-ever global, multi-stakeholder plan to ensure that crisis-affected people gain access to affordable, reliable, sustainable and modern energy services by 2030.”

Heat pump makes use of low-temperature solar energy for space heating

Submitted by Baerbel Epp on March 29, 2018
Markus BeslmeislWith round about four decades in business, the German-Slovak Thermosolar Group is one of the oldest solar thermal manufacturers in Europe. It began producing collectors in 1972 in Slovakia and started offering a special evacuated flat plate collector in 1997. Last November, long-time sales manager Markus Beslmeisl (see photo) acquired the remaining shares in the company from Johann Kollmannsberger. Solarthermalworld.org spoke with the new managing director about Thermosolar’s special solar heat pump system, called Duo Premium.

“Need to include solar in architectural education”

Submitted by Baerbel Epp on March 28, 2018
Sylvio PodestaBrazil ranks fourth on the list of the world’s largest solar thermal markets, but very few installations have been integrated into a facade or roof. Sylvio de Podestá is the architect behind one of the buildings that have roof-integrated collectors. At this hotel in Belo Horizonte, also known as Brazil’s solar capital, the collectors are at a slope guaranteed to maximise efficiency (see image). Usually, solar systems are added during construction, long after the design stage.

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.

Thermosiphon market rebounds in Italy

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.

Namibia’s path to a solar thermal future

Submitted by Baerbel Epp on January 19, 2018
Namibia Workshop SoltrainThe Namibia Solar Thermal Technology (STT) Roadmap outlines the country’s path to 1.5 million m² of collector area by 2030. The aim is to have an average 0.5 m² installed per inhabitant by then (see the attached document). During a workshop in Windhoek last June, stakeholders from policy and administration voiced their unequivocal support for the implementation of the STT Roadmap 2030, which was developed by a consortium of experts and funded by SOLTRAIN, the Southern African Solar Thermal Training and Demonstration Initiative.

Guide for potential investors

Submitted by Baerbel Epp on January 15, 2018
Solar Thermal NowAgainst the low standing of solar thermal technology, the British Solar Trade Association (STA) has launched a 16-page colourful brochure. The guide called Solar Thermal Now - A guide for domestic, business & public sector investors showcases the technology’s merits, the flexibility and broad application of solar thermal, while highlighting its enormous potential for cost and carbon savings. The report is available for download attached and association members can order hard copies. The brochure reveals some of the misconceptions in the support structure for ST in UK.
