Manufacturer Founds Air Collector Association SAHWIA

Submitted by Baerbel Epp on June 23, 2009

solar air collectors of Solarwall” Air collector companies exist very much in the shadows of the manufacturers of water collectors. Therefore a Solar Air Heating World Industry Association (SAHWIA) is necessary. But not all manufacturers are pleased with the procedure that lead to the association’s founding. Photo: Solarwall

Mechanical Equipment & Control Strategies for a Chilled water and a Hot water system (2008)

Submitted by Hans Craen on April 19, 2009

This report from 2008 falls within the framework of the Internal Energy Agency’s Solar Heating and Cooling Programme.

The objective of this report is to undertake pre-normative research to develop a comprehensive and integrated suite of building energy analysis tool tests involving analytical, comparative, and empirical methods.

These methods will provide for quality assurance of software some of which will be enacted in specific standards to be used for certifying software used for showing compliance to building energy standards.

Barriers to Technology Diffusion: the Case of Solar Thermal Technologies (2006)

Submitted by Hans Craen on March 27, 2009

This joint paper from the OECD and IEA (October 2006) looks into the different barriers that exist which prevent solar thermal technologies to deliver its real potential. Next to listing the barriers, the document also looks into means to overcome these, the existing technologies & markets and identifies best practices which can be used by policy makers in both industrialised and developing countries.

Three barriers to diffusion are analysed in more detail:

(1) Technical barriers,

(2) Economic barriers and

Cape Town: Draft of Solar Water Heating Bye-law

Submitted by Baerbel Epp on March 25, 2009

Thermosiphon system in Cape townCurrently, solar water heating systems have hardly penetrated in Cape Town, South Africa. Only 2 % of city’s 906,000 households use solar energy. The planned bye-law should boost the market to 76,000 newly installed system in the next two years, but has been delayed due to continuous legal obstacles. Photo: Sustainable Energy Africa

Enlarging Testing Facilities for SRCC in the USA

Submitted by Baerbel Epp on February 15, 2009

The extension of the federal tax credits by eight years and the election of Barack Obama have suddenly made the U.S. market for solar thermal energy far more attractive. The importance of imports of collectors and systems is growing. The number of flat plate and evacuated tube collectors has increased more than tenfold within three years according to the statistics of the Energy Information Administration (EIA) from 3,000 m2 (2005) to 36,000 m2 (2007).

Dynamic Market Growth in the UK

Submitted by Baerbel Epp on February 2, 2009

The UK was still one of the most dynamic solar thermal markets in Europe in 2008 – despite the worldwide economic crisis. According to the British Solar Trade Association (STA), the amount of solar thermal collectors installed countrywide in 2008 grew by 50 % to 81,000 m2 (57 MWth)."

New Association and Subsidies in Thailand

Submitted by Baerbel Epp on November 29, 2008

The solar thermal sector in Thailand finds its voice. After one year of preparation, the Solar Thermal Association (STA) is very close to being approved by the government. “We expect approval by January 2009”, says STA president Somsak Chutanan, CEO of the company Infratech Engineering & Services. It will be exactly one year after officially founding the association in January 2008.

The Agenda for Solar Thermal in SEIA

Submitted by Baerbel Epp on October 28, 2008

The solar thermal division of SEIA, the Solar Energy Industries Association in the USA, should be strengthened. This is the decision of a meeting of solar thermal stakeholders during the conference and exhibition Solar Power in San Diego in the middle of October. Representatives of the solar thermal industry as well as of the Solar Rating and Certification Cooperation (SRCC) discussed two different options.

Spain: Solar Obligation since 2006

Submitted by Baerbel Epp on August 29, 2008

In March 2006 the Spanish Government passed the new Technical Buildings Code (CTE). It has been the most significant reform of the country’s building sector in decades. The law covers safety, health and noise protection issues in buildings, and it deals with sustainability and energy efficiency aspects. The solar sector of the CTE includes an obligation regarding the use of solar thermal energy in all new buildings and buildings undergoing major renovation and/or changes of use. Solar energy is supposed to cover 30 to 70 % of the domestic hot water demand.
