    Optimised control strategy for solar district heating in Italy

    Despite its small size, the solar district heating system in Lodi, close to Milan, is one of few in Italy to feed surplus heat into a local network. In March 2017, Linea Reti e Impianti, the public utility based in this city of 45,000, started buying heat produced by a 192 m² solar thermal...

    Green hotel in Italy’s mountains

    Solar thermal performs well even in high-mountain areas during winter season. The installation shown in the photo is proof that combining solar and other renewable technologies, such as biomass boilers and a solar-assisted heat pump, results in a synergy that can be very productive. The...

    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...

    How to identify suitable areas for SDH

    Though the availability of areas for large solar district heating plants remains a major point of contention, there are ways to expand the market. They include detailed local heat plans, the use of unconventional, e.g., polluted or contaminated, areas, and awareness raising among public and...

    Building-integrated solar envelopes: barriers to deployment

    Active and passive solar systems integrated into building envelopes are key to combatting climate change. However, there are many barriers which confine current solutions to the demonstration stage and prevent them from going mainstream. To increase the size of the market, researchers have...

    Sweden: Pioneer of solar district heating

    When it comes to district heating, Sweden has made the switch from fossil fuels to biomass and waste heat (see chart). As early as 2015, biomass provided 46 % of the energy in district heating networks across the country, followed by 24 % from waste incineration and 8 % from industrial...

    Solar thermal and biomass – a winning solution for district heating

    Biomass may be cheap and carbon-neutral, but a solar upgrade of biomass-fired district heating could further improve efficiency and reduce local emissions. For example, solar heat helps avoid having to start up and shut down wood-chip boilers or operate them at partial load. It can even...
