Project Value: £4,500,000.00

Term: October 2021 – December 2022

The City of Edinburgh Council

May and Gunnet Court

This energy efficiency project involved the external and internal retrofit of two nine-storey blocks, comprising 96 mixed-tenure flats, to meet PAS 2035 standard. Delivered in North Edinburgh, the project aimed to enhance energy performance, improve resident comfort, and reduce carbon emissions.

Initially designed to upgrade the building envelope with external wall insulation and ceiling insulation around newly installed triple-glazed windows, the project evolved to achieve full PAS 2035 compliance. This included appointing key retrofit roles and collaborating closely with design teams, manufacturers, and the supply chain to integrate advanced energy-saving measures.

Working with partners, we developed a comprehensive retrofit design and ventilation strategy. Early cost modelling allowed for adjustments that secured additional ECO funding, optimising the scope to deliver enhanced value and client savings for the City of Edinburgh Council.

Project Goals

The client came to us with several goals for their North Edinburgh project. They sought to improve energy efficiency across two nine-storey blocks, aiming for significant upgrades to reduce energy consumption and heating costs for residents. They also wanted to address safety and durability issues, particularly with the existing roof and corroded steel balconies.

A major challenge was engaging with the diverse tenant demographic, ensuring effective communication and access during intrusive internal upgrades like ceiling insulation, window installations, and ventilation improvements. Additionally, the client sought to maximise ECO funding while maintaining cost efficiency and achieving high-quality retrofit outcomes which aligned with their vision for innovation.
