    Online database on advanced PCMs

    Compared to water, phase change materials (PCMs) offer more capacity to store heat in tanks. As a consequence, researchers in all corners of the world have been developing new materials and their properties. To ensure the employment of a shared methodology and the use of equivalent terms to...

    EU labelling: “Solar devices to be classified as heaters”

    The German-based Solar Heating Initiative has developed a new calculation method to label solar thermal systems based on the Ecodesign Directive 2005/32/EC. It put the method, which allows for a fair assessment of solar thermal energy input into a heating system, forward for consideration...

  • collector labels Solergy (left) and Solar Keymark (centre top) as well as the EU Energy Efficiency label (right)

    Three labels in Europe – what are the differences?

    Labels and trademarks should give the end-consumer a clear feedback on the quality and performance of the labelled product. Currently there are three labels available for solar products or solar assisted heating systems in Europe, so there is an increasing need to explain the differences to...

    On-site collector testing: new standard in development

    Once a large solar field is set up at its designated location, what tests can be conducted to show that it performs as expected? Soon, the IEA Solar Heating & Cooling Programme may have an answer to this question, as it is working on internationalising Denmark’s testing procedure. No...
