    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 (LA's: cities of Rotterdam, Breda, Antwerp, and Mechelen; EOS Oostend; SPEE Picardie; Kent County Council) identified, tested and evaluated new ways of supporting homeowners in local target areas using new communication policy approaches involving web portals, pop-up centers, demonstration exemplars and easy access to home energy monitoring systems (HEMS). An integrated Triple-A strategy was jointly developed with TU Delft, University of Ghent and Eandis/Fluvius. This resulted in a model that helps the LA's to identify strategic priorities and activities they can develop to improve supporting single-family home-owners in their quest for renovation measures.

    Using this framework, LA's developed both their virtual and physical consultancy for homeowners. LAs' existing web portals were adapted with additional web modules developed by the LA's, using both qualitative and quantitave research as well as co-creation with local stakeholders.

    The 7 LA's also launched local pop-up consultancy centers in target areas, either on a fixed location or in a mobile format. Both consultancy developments were supported by literature research, questionnaires, interviews, an inventory of low-carbon technologies and financial schemes, jointly organized business modeling and co-creation workshops and local events. 11000+ persons already visited the pop-up centers and the pop-up idea was copied by multiple other LA's.

    In 8 target areas the LA's also 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 2479 demo homes achieving carbon savings of 3945 tonnes of CO2 per year, and have completed 1599 thermographic surveys and 199 feedback surveys.

    All partners also investigated the use of HEMS as a means to influence homeowner decisions, and consequently identified promising ways of using, adapting, selecting and procuring HEMS, as well as improved ways to collaborate with local stakeholders.

    The project is succesfully reaching its expected outputs and deliverables. Various key findings were already made pubic in scoping and evaluation reports. The project is now preparing a final dissemination event in each country.
