Construction of Solar Collectors for Warm Water – Practical Guide (2014)

Submitted by Raquel Ponte Costa on March 5, 2015

WECF,  Women of Europe for a Common Future, has published a practical guide explaining how to build a cheap and efficient solar water heating system, using local knowledge and materials and which can be used all year long. The document provides information on the different parts of a solar water heater, on how to build solar collectors and a heat exchanger tank.  It also gives further information on other solar water heater models.

Analysis of Austrian SDH Plants Constructed in the Framework of a National Funding Programme (2014)

Submitted by Raquel Ponte Costa on March 5, 2015

This presentation was given by F. Mauthner of AEE INTEC at the 2nd international Solar District Heating Conference in Hamburg on 3 – 4 June 2014.  It outlines the evolution of District Heating in Austria since the 1950’s with an emphasis on solar district heating (SDH).  In 2013, there were 25 SDH plants of over 500 m², representing 35.000 m² of collector area.  The presentation also provides information on national funding programmes, which cover 50% of the additional costs a solar thermal application require.  Up until now, approximately 90 Mio Euro funding has been provided.

Austria: Task 42 Meeting on Compact Thermal Energy Storage Systems

Submitted by Baerbel Epp on March 3, 2015
Task 42 MeetingIEA-SHC Task 42, entitled Compact Thermal Energy Storage, has entered into its final year and will end in December 2015. In February 2015, 44 scientists met for the 13th Experts Task Meeting in Vienna, Austria, to discuss the characterisation and development of materials for latent heat storage systems. This included phase change materials (PCM) like paraffin and thermo-chemical materials (TCM), such as sodium hydroxide solutions or zeolites. During the three-day meeting, the task members also visited the cogeneration plant Simmering in Vienna. The photo shows them in front of two pressurised water tanks with a total volume of 11,000 m3. The tanks are charged and discharged with 145 GWh annually and are operated to decouple heat energy production from demand in the district heating network of Vienna.

RE-Invest Establishes India as New Global Renewable Hub

Submitted by Baerbel Epp on March 3, 2015
RE-Invest 2015RE-Invest 2015, the first Renewable Energy Global Investors Meet & Expo, organised by the Ministry of New and Renewable Energy (MNRE), showcased the Indian government's commitment to the development and uptake of renewable energy in India, in order to meet the national energy requirement in a socially, economically and ecologically sustainable manner. The conference held in New Delhi from 15 to 17 February brought together the global investment community and renewable energy stakeholders from India. The photo shows the industry panel Make in India II, which was attended by representatives of well-known renewable energy manufacturers, among them D V Manjunatha, Founder and Managing Director of flat plate collector and tank manufacturer Emmvee Solar Systems (first from left). He bought back the 50 % stake in his company from Danish Solarcap in June 2014 and is now again the sole owner of a company with a turnover of between EUR 9 and 11 million and around 200 employees.

Global view: Solar Thermal Markets Transitioning from Residential to Commercial

Submitted by Baerbel Epp on March 3, 2015
TransitionChange is coming to the world’s solar thermal markets: Single-family homes – currently the most important sales segment – are going to lose their significance in the future. Most solar thermal manufacturers across the globe predict their sales to be dominated by other segments over the coming years. These are just some of the results from international survey ISOL Navigator December 2014, a study published by German agency solrico. 365 solar collector manufacturers and solar thermal system suppliers from all corners of the globe participated in the survey. The figures in brackets show the number of questionnaires which were included in calculating the regional averages.

“Very few countries have policies explicitly supporting renewable deployment in the industry sector”

Submitted by Baerbel Epp on March 2, 2015
Ruud KempenerThe International Renewable Energy Agency (IRENA) published two technology briefs last week. The 40-page documents, one entitled Solar Heat for Industrial Processes, the other Solar Heating and Cooling for Residential Applications, give a brief global overview of the market and technology development, including some recommendations for policy makers. It is the first time that the solar thermal sector is in the focus of a technology brief. The studies were published under the Energy Technology Systems Analysis Programme (ETSAP) of the International Energy Agency. Solarthermalworld.org spoke with one of the authors, Ruud Kempener, Technology Roadmap Analyst at the IRENA Innovation and Technology Centre in Bonn, Germany.
 

Abu Dhabi: IRENA´s Headquarters Become First 4 Pearl Office Building

Submitted by Baerbel Epp on March 1, 2015
IRENA HeadquaterThe future headquarters of the International Renewable Energy Agency (IRENA) represent the first office building in Abu Dhabi to be awarded the 4-Pearl Estidama Construction Rating Certificate. According to the Estidama website, the 2010 rating system was the first building certification code to be adopted in the Middle East. Estidama, which means sustainability in Arabic, was implemented by the Abu Dhabi Urban Planning Council (UPC) and aims at “creating more sustainable communities, cities and global enterprises”. In addition to low energy and water consumption, credit points are given for an integrated planning process, as well as ecological building materials and an innovative building design. IRENA’s new headquarters achieved 115 points above mandatory and therefore gained the 4 Pearl rating.

Europe: Conferences That Offer Solar Heating and Cooling Sessions in First Months of 2015

Submitted by Baerbel Epp on February 28, 2015
WSEDEurope’s conference season now starts new after the end of 2014: This week, the World Sustainable Energy Days began in Wels, Austria, with a special focus on Nearly Zero Energy Buildings. Solarthermalworld.org is offering information about all important events on the Calender of Events and will highlight some upcoming conferences in this news piece. The variety of solar heating and cooling topics is great, but the technology remains on the sidelines during most conferences. The Calender of Events lists 70 renewable conferences and fairs until November 2016.
