The Triple-A project aimed to install demonstration exemplars of a variety of low-carbon technologies to increase awareness and adoption of these (building/construction) technologies by homeowners. Through this, the adoption of low-carbon technologies became normalised and created ambassadors for the technologies who can influence other homeowners. This document aims to outline the process used to implement these demonstration homes and provides examples and guidance from the experience of the project partners. The demonstration exemplars implemented ranged in their approaches but were grouped into four different types: • Model A: Utilising new and innovative technologies. • Model B: Whole house or nearly-zero carbon retrofit. • Model C: Large scale or community wide mass retrofit. • Model D: Longer term phased retrofit. These models were explored using a structured approach, taking into account various aspects. These stages are discussed in more detail throughout this document, which includes the lessons learnt at each stage:  Identifying suitable target areas in 8 local authority regions for single-family home renovations  Exploring citizen segments in target areas and related engagement opportunities  Identifying suitable financial incentives for engaging single-family homeowners  Testing installation of technologies through demonstration homes  Evaluating CO2 reduction of demo exemplars and awareness raising @en

Frontrunner local authorities aim to achieve a market acceleration in the owner-occupied single-family home renovation sector by increasing awareness of – and enabling access to – low-carbon technologies in residential target areas. With their easy availability, adaptability, and possible mobility, pop-up consultancy desks can provide local outreach in target areas for achieving home renovation measures. This research looks into the adoption, use and effectiveness of fixed or mobile energy consultancy desks in target areas organized by local authorities. Local authority initiatives are described, compared and evaluated regarding various parameters. For two local authorities in the Netherlands, Rotterdam and Breda, pop-up initiatives are elaborated upon, examining the number of visitors, needed resources and experienced barriers and opportunities. The results show that both longer-term fixed and short-term mobile consultancy pop-ups can be suitable for providing energy awareness and consultancy in target areas, and for stimulating the local adoption of low carbon technologies. The results clarify pros and cons of both approaches and the elements of business models that can be used by other local authorities. Recommendations for business models for self-supporting consultancy in target areas and guidelines for local authorities are planned. For sustaining the pop-ups, collaboration is recommended with other partners.@en
