IEA SHC Task 53: Innovative Solar Cooling Systems

Submitted by Baerbel Epp on February 28, 2017
IEA SHC Task 53The biggest challenge for a small market like the solar cooling one – which has still a long way to go – is how to reduce system costs. One way to achieve this objective besides increasing market volume is standardisation. Companies from around the globe have responded to the challenge by developing pre-engineered solar cooling kits. To provide a better overview of the innovative technologies in this field, the researchers of IEA SHC Task 53, New Generation Solar Cooling and Heating Systems, collected technical data on 10 small to medium solar cooling units and published them in table form (see the attached document). The list includes market-ready as well as close-to-market solutions.

Energie 2017, Den Bosch

Submitted by Baerbel Epp on October 23, 2016
Energie is one of the largest live events in the Netherlands on energy-saving technology and sustainable energy. Whether it concerns a specific improvement or an integral approach, from reducing energy consumption to stricter purchasing policies, Energie is the place to be. With a broad and varied program and attention for innovation, the fair has gained an unmistakable status. 2017’s edition will take place in Den Bosch from 10 to 12 October.
 

TASK 45 / 55: Guidelines on How to Design Seasonal Storage

Submitted by Baerbel Epp on August 1, 2016
Bore Hole StorageSeasonal storage is a key component in the transformation of today’s energy industry. Besides storing energy in summer for heating in winter, it can also be used to save waste heat from the industry and to increase the electricity production from biomass CHP plants. Experiences gathered with the technology during case studies were summarised as part of the study Seasonal thermal energy storage – Report on state of the art and necessary further R+D, which was published by Task 45, Large Scale Solar Heating and Cooling Systems, of the IEA SHC programme. Together with the Guidelines for Materials & Construction on the two most common storage types, borehole (see the chart) and water pit, it provides a good overview of the current advancements in this field (all three documents attached). Additional research into the design of seasonal storage will be carried out in follow-up Task 55, Towards the Integration of Large SHC Systems into District Heating and Cooling (DHC) Network. Interested stakeholders have been invited to join the kick-off meeting of Task 55 in Graz, Austria, between 19 and 21 October (see contact details below).

Certification – A Marketing Tool for Solar Thermal Energy Professionals

Submitted by Baerbel Epp on April 11, 2016
To have a solar thermal system on the roof of one’s home may be a good thing if it does work well. But the probability that solar water heaters perform as they should and as long as they are supposed to is higher when they are installed by real experts familiar with the best practices of the industry. But how is one to know whether an installer is a real professional? Certification may be a viable indicator of whether or not a plumber can be trusted with installing a modern solar thermal system. That is why certification is gaining importance not only in manufacturing, but also in other parts of the industry. 
 

IEA SHC: Task 56 Kick-Off Meeting on Building Integrated Solar

Submitted by Baerbel Epp on March 30, 2016
Norway AventaAlmost 30 experts from 25 partner organisations met in Bolzano, Italy, on 21 and 22 March for the kick-off meeting of IEA SHC Task 56, Building Integrated Solar Envelope Systems for HVAC and Lighting. The overall goal of the task is to find out “why some ways of solar integration do work, while others don’t,” as the Task Operating Agent and Coordinator of the Sustainable Heating and Cooling Systems research team at Italian institute EURAC, Roberto Fedrizzi, put it – and, of course, to find measures to improve solar technology integration into façades and roofs. The photo shows a residential home in Stavern, southern Norway, where 7 m2 of solar collectors have been integrated into window frames in the south-facing facade, contributing to both domestic hot water preparation and space heating.

Solar Cooling: From Research to Market Competitiveness

Submitted by Baerbel Epp on October 6, 2015
Otti SAC 2015Diligent research on small scale low-temperature chillers, the launch of a new generation of compact solar cooling units and large-scale plants able to compete economically with conventional cooling solutions: These are just some of the main trends which were discussed during the 6th International Conference on Solar Air-Conditioning organised by German company East-Bavarian Institute for Technology Transfer, OTTI, Rome, Italy, on 24/25 September. The photo shows Conference Chairwoman Prof Ursula Eicker from the University of Applied Sciences, Stuttgart, Germany (forth from left in first row) together with the international scientific committee consisting of researchers from Germany, Spain, Greece, Italy, France, China, Austria and Cyprus.

Netherlands: Ambitious Targets for Sluggish Market

Submitted by Baerbel Epp on July 20, 2015
NetherlandsThe newly installed collector area in the Netherlands has not grown by a significant margin since 2011, and it even decreased slightly in 2013 (see the chart on the left). According to the Dutch industry association Holland Solar, this is to be considered a fair outcome, as the number of new residential construction permits has declined in recent years. Residential construction is by far the most important market for solar thermal technology in the country. There have not yet been any statistics on the newly installed collector area in 2014, but considering that the number of building permits was twice as much in 2014 than in the previous year, experts estimate that solar thermal sales will at least have remained at their previous levels. The authors from the German-Dutch Chamber of Commerce, DNHK, see a silver lining for 2015 in a market analysis published in May 2015 in the framework of the German Renewable Energies Export Initiative (see the attached PDF in German).

Solar Thermal Power 2020: Exploiting the Heat from the Sun to Combat Climate Change (2003)

Submitted by Raquel Ponte Costa on June 21, 2015

This study is a product of a partnership between the European Solar Thermal Industry Association and Greenpeace.  It provides information on the current state of solar thermal technology, and develops a scenario for where the solar thermal market could be by the year 2020.

Solar Days 2015: Individual Schedules in Eight Countries

Submitted by Baerbel Epp on May 31, 2015
LuftballonsThe European Solar Days (ESD) seem to have lost some momentum. Since the European Union stopped co-financing the ESD, it seems that several national partners among the so far more than 20 participating countries have found it harder to get monetary support for their work and all of the activities required for coordinating the Solar Days campaign at national level. Still, the European Solar Thermal Industry Federation (ESTIF) has been able to agree with several previously participating countries on a common schedule from 1 to 15 May. Austria, Switzerland, Norway, Poland and Serbia have already told ESTIF about their activities in May (see the table below). Belgium, Denmark, Slovenia and Spain, however, will not offer any solar days this year. The photo shows an event in an primary school in Switzerland
