SOLARGE: objectives (2/3) HOUSES, HOTELS, PUBLIC AND SOCIAL BUILDINGS IN EUROPE

  • SOLARGE is a European co-operation project to open up markets for large solar thermal plants, (>30m2) for multi-family buildings (MFH), hotels, public and social buildings

    • Analysis of existing projects and identification of market obstacles and opportunities

    • Identifying factors for success concerning technology, project development and realisation

    • Information and sensitisation of target groups in Europe

    • Compilation and communication of European good practice projects and solutions

    • Support for national and European energy policies

    • Development of proposals to improve existing political framework conditions for CSTS applications

    • Europe-wide dissemination of results


Solarge realisation 3 3
SOLARGE: realisation (3/3) HOUSES, HOTELS, PUBLIC AND SOCIAL BUILDINGS IN EUROPE

  • Training and further education measures for the supply side e.g. manufacturers and architects

  • Events concerning the above subjects in the partner countries

  • Compilation of well-documented best practice projects

  • Interviews with plant operators, manufacturers and investors

  • Information campaign for investors

  • Support for municipalities and decision makers

  • Positioning the issue at events and conferences

  • Provision of information material via internet

  • EU-wide dissemination of the project results: interactive project web-site, market studies, good practice project database: see www.solarge.org

Conclusion and recommendations
Conclusion and recommendations HOUSES, HOTELS, PUBLIC AND SOCIAL BUILDINGS IN EUROPE

  • Solar thermal systems for MFH sector is a promising target market (350 kWth ~0,9 million m2 per year)

  • Spain and France represent 55% of this market

  • Lots of system configuration are applied in this market, with all have advantages and disadvantages

  • Bottom line: apply sound solutions that last for > 20 years without technical problems and a minimum of maintenance

  • How? Apply simple and solid configurations, meaning:

    • As few as possible (moving) parts

    • Avoid complex hydraulic solutions

  • Do they exist? …. Yes!
