Our Retrofit Assessors are fully trained and qualified to undertake a retrofit assessment for dwellings in accordance with PAS 2035. The activities completed within the retrofit assessment include the production of an RdSAP assessment, a detailed floor plan, a condition report and an occupancy assessment.

The data collected from these sources is used by the Retrofit Coordinator (a service we can also offer) to formulate a Medium-Term Improvement Plan. We are also accredited DEAs (Domestic Energy Assessors) therefore have extensive knowledge and experience with RdSAP methodology and assessment of existing dwellings.

Our retrofit assessors will contact the client and arrange to visit the property. The process of the assessment is to look at the history and condition of a building, and its suitability for improvement, all analysed systematically. This type of analysis helps to establish the condition of the building and to identify defects and performance failures. It also establishes how defects have arisen and identifies the work that should be carried out not only to repair them and restore performance, prior to retrofit, but also to prevent them from recurring. It is important when a dwelling is assessed for retrofit, and when improvement options are evaluated, that the dwelling is treated as a system comprising the building envelope (or building fabric), the building services (ventilation, heating, hot water, lights and appliances), any LZC technologies or ‘renewable energy systems’, and also the behaviour of the occupant. The occupants are key elements of the system because they require certain conditions for comfort, they also operate energy-using lights and appliances; and give off heat.
