Our Role

Retrofit Assessor, Retrofit Designer & Energy Assessor.

______ Project Overview
This retrofit project for Riverside Scotland will see whole-house retrofit and upgrading works carried out on 30 units of existing social housing located in Kilwinning, North Ayrshire.

30 one-bedroom bungalows in Pennyburn will be improved to reduce energy usage, lower tenant energy bills and make the properties heat-pump ready. The existing homes currently achieve EPC Band D, and this will be improved to a Band B rating, following completion of the works. The project follows an archetype approach.

______ Our Scope
As the appointed Retrofit Assessors, Carbon Futures was responsible for assessing the existing condition of the properties, producing existing drawings and reporting on suitable energy efficiency measures. Energy modelling was carried out in SAP10 to determine the existing energy profile of the archetype properties. As part of the design process, further energy modelling was carried out to help determine a suitable suite of measures to be installed. Thermal bridging analysis was carried out to check surface temperatures at vulnerable junctions. The final selection of measures was decided through a collaborative approach with the team and linked to funding opportunities. Drawings and specifications were produced for the chosen measures and building warrants obtained. Key detailing relating to junctions and fire requirements were included. Carbon Futures are also providing technical support during construction as needed.
