    Common challenge

    The building sector accounts for approximately 35% of CO2 emissions. About 50% of the dwellings in the partner regions consists of single-family housing in the owner-occupied sector. Although there is an enormous potential to reduce CO2 emissions by stimulating home-owners to adopt low-carbon technologies, the current average renovation rate is just around 1%. ‘Triple-A’ unites 7 local authorities (LAs) pioneering in renovation policies in their ambition to achieve a real market acceleration in this part of the building sector resulting in a significant reduction in CO2 emissions.

    Main Achievements

    Seven local authorities (LAs: cities of Rotterdam, Breda, Antwerp, and Mechelen; EOS Oostend; SPEE Picardie; Kent County Council) identified and tested new ways of supporting homeowners in local target areas using web portals, pop-up centers, demonstration exemplars and easy access to home energy monitoring systems (HEMS). This Triple-A strategy was refined with input from TU Delft, University of Ghent and Eandis/Fluvius, supporting homeowner decision processes, evaluating experiences and developing marketing plans and implementation.
    LAs built up both virtual and physical consultancy for homeowners. Building on PP's experiences with existing web portals, a questionnaire towards LAs, an inventory of low-carbon technologies and financial schemes, a public report and multiple workshops on LA web portal development, LAs supported the adoption and identification of LA web modules for easier access to low carbon technologies by homeowners. Subsequent activities helped the LAs to identify, select and realise new web modules in co-creation with stakeholders and LAs.

    The 7 LAs also launched local pop-up consultancy centers, either on a fixed location or in a mobile format. This development was supported by literature research, a questionnaire to local authorities, interviews with consultancy centers, an inventory of low-carbon technologies and financial schemes used by partners, and a jointly organized business modeling workshop, a comprehensive report and media and events supporting local pop-up consultancy centers. 7500+ persons visited the pop-up centers.

    In eight target areas the PPs demonstrated demo exemplar management using the input from jointly organized workshops, brainstorms, meetings, buddy cooperation, standardised contracts and information about finance, funding and demo models. Overall, PPs have installed 1640 demo homes achieving carbon savings of 3383 tonnes of CO2 per year, and have completed 1599 thermographic surveys and 199 feedback surveys so far. 

    PPs also scoped the use of HEMS with stakeholders to influence homeowner decisions, and consequently identified promising ways of using, adapting, selecting and procuring HEMS.

    Project indicators were developed and are being monitored. PPs work with a dissemination strategy, using, a Triple-A group on LinkedIn, articles, news items, presentations, banners, workshops, and preparation of final roadshows in 2020.
