2010 was a good year for the solar thermal industry in Canada. The total newly installed collector area (brown line) grew by 54 %, from 129,418 to 199,491 m2. Air collector sales (red line) doubled and - for the first - overtook the solar swimming pool market (blue line), which is more or less stagnating. With 150 %, the segment of glazed solar water collectors (pink line) experienced the highest growth, although the 20,000 m2 sold in 2010 make it still a low-level market.

This presentation was created by Rob Dumont of the Alaska Center for Appropriate Technology, which promotes sustainable economic development in Alaska. It covers passive solar heating design and thermal mass construction.
Solar thermal technology has still a long way to go in Southeast Asia before being recognised as the reliable and valuable alternative energy source it is appreciated for in other parts of the world. Solar heating and cooling technology did not play a major role at Singapore’s Clean Energy Expo Asia (CEEA) at the beginning of November 2011. The trade fair and conference is part of the Singapore International Energy Week, which is the biggest event of its kind in Southeast Asia. Only two international solar thermal exhibitors found their way to Singapore: Austrian engineering company SOLID (see photo) and hydraulic specialist Oventrop from Germany.

This case study contains a brief synopsis of a solar thermal water heater project that was performed by Todd Lavery of Union College in New York.
The Solar Heating and Cooling Programme of the International Energy Agency (IEA SHC) is planning to start its own annual conference in 2012. The conference name SHC has been chosen in reference to the long-established research programme IEA SHC. The full name is International Conference on Solar Heating and Cooling for Buildings and Industry. The 1st SHC will take place in San Francisco from 9 to 11 July 2012 – in cooperation with the Intersolar North America (10 to 12 July 2012).
This case study is the result of a partnership between New Zealand’s Energy Efficiency and Conservation Authority (EECA), the country’s dairy farmers and technical experts, showing the benefits of solar water heating and waste heat recovery systems used to reduce energy costs.
The global breakthrough of solar thermal will depend on how well the industry masters the challenge of cost-effective tank and collector manufacturing. This is the key issue of the 3rd SMEThermal conference on 7 February 2012 in Berlin, Germany. The international event is dedicated exclusively to process optimization, automation, and new materials in the solar thermal industry. The organizer, Berlin-based Solarpraxis, launched the complete programme at the end of October (see attached pdf).
During the meeting in Paris in October 2011, the Solar Keymark Network has accepted an extension of the Solar Keymark Scheme Rules. In the future, Solar Keymark will be available for both solar water heater stores and concentrating solar collectors. At the same meeting, the Solar Keymark Network has approved the new Annual Collector Energy Output Calculation Tool as a standard measuring tool for all Solar Keymark certified collectors. The energy output calculated with it can from now on be found on all Solar Keymark data sheets.
