Quality Assurance Studies Detect Failures in Conventional Heating and Hot Water Supply

Dear Solarthermalworld.org Reader, 

 

Whether a small residential system or a 2,000 m2 solar process heat plant – inspections and monitoring can definitely improve the performance of a majority of installations. In this newsletter, we take a closer look at two quality assurance studies. In Austria, 40 commercial systems between 100 and 2,000 m2 were monitored over the first year in operation. In Italy, 430 mostly residential hot water systems were inspected after an average of five years in operation. Both studies, as different as they may be, came to the same conclusion: Despite the detection of a high number of smaller and larger problems, most of these were found in the conventional part of the heating and hot water supply system. Actually, only 43 % of the 115 problems were linked to the solar circuit in Austria. In Italy, only 8 % of the systems had failures of the heat transfer fluid and less than 3 % showed damage in the solar collectors. The difficulties most often encountered by the Italian inspection teams were undersized pipe insulation, incorrect installations of the expansion vessel, as well as leakage in the primary circuit and in the valves.

India: Solar Process Heat with less than 18-Month Payback Period
by Jaideep Malaviya

“Where there’s a will, there’s a way” is the slogan at Sharman Shawls, one of India’s leading garment industry and export companies. Based in Punjab state in northern India, Sharman Shawls uses diesel to meet the hot water requirements for dyeing, bleaching and washing garments. The enterprise’s daily consumption is close to 200,000 litres of water and the processes require almost 1,700 litres of diesel per day. 180 flat plate collectors preheat hot water to 80 °C, saving 82 litres of diesel at 300 days a year. Space constraints have limited the diesel saving per day to 5 %.

Position Paper: Actions Needed to Pave Way for Net Zero Energy Buildings
by Bärbel Epp
 

Over 40 % of primary energy use and 24 % of greenhouse gas emissions are attributed to global energy use in buildings so architects and builders are being posed the challenge of creating highly energy-efficient structures. One vision promoted by stakeholders in many countries worldwide is Net Zero Energy Buildings. To provide an analysis of the market potential and the actions required for a market uptake of this architectural design approach, the IEA Solar Heating and Cooling Programme published a position paper entitled SHC Net Zero Energy Solar Buildings in June. The 10-page summary is based on the insights of 82 experts from 19 countries, who have been conducting research within a joint IEA SHC Task 40 and Annex 52 of the Energy in Buildings and Communities Programme over several years.

ESTIF: Don’t Miss Opportunities of Solar Heating and Cooling
by Bärbel Epp

The European Solar Thermal Industry Federation is expanding its services in policy advocacy and communication. In July, ESTIF started a new series of Webmeetings with national trade associations in form of webinars. During the first online meeting, ESTIF´s policy officer, Stefano Lambertucci, informed the association representatives about two major policies: the outcomes of the Renewable Energy Progress Report and the preparations for the EU Strategy on Heating and Cooling by the European Commission, which is going to be published in the last quarter of 2015.

IEA SHC: Mutual Recognition of Test and Inspection Reports Saves Industry Costs
by Bärbel Epp
The work of the Global Solar Certification (GSC) Network is expected to continue within the framework of the IEA Solar Heating and Cooling Programme (SHC). The Executive Committee of the IEA SHC approved the set-up of a task definition workshop in Paris on 7 October 2015, in order to establish a new task under the title International Standards & Global Certification. “Collector and system manufacturers selling products in several countries, as well as representatives of certification bodies, test labs and inspectors from all around the world are invited to join the meeting in Paris and become members of the international research community discussing the harmonisation of standards and certification schemes worldwide,” explains Jan Erik Nielsen, Manager of the GSC Network and initiator of the new task.

Italy: Solar Steam for Cheese Production
by Riccardo Battisti
 
Direct steam production, 35,000 litres of diesel saved per year and the advantage of the Italian incentive scheme for renewable heat: All these favourable conditions allowed a small dairy in Sardinia to choose a concentrated solar thermal plant with Fresnel collectors for generating 200 °C steam. The steam is used to supply heat to the industrial processes for cheese production. The investment of EUR 400,000 will have a payback period of about 4 years.
