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
