We were engaged to deliver a coordinated Energy Strategy and overheating assessment along with BREEAM certification for this large-scale, mixed-use development post Reserved Matter submission, to ensure the developments’ resilience to a changing regulatory framework.
This long-running development has been subject to changing regulatory requirements. Updates to Part B of the Building Regulations, required a change from steel framing systems (SFS) to blockwork, impacting the Energy Strategy and thermal bridging considerations. This requirement emerged during construction. We guided Redrow to deliver the most straight-forward route to compliance, given existing design constraints. Through a coordinated review of u-values and thermal bridging, we were able to demonstrate design flexibility to meet regulatory requirements and meet the client’s brief.
The development was also conditioned to deliver BREEAM Very Good and deliver dwellings compliant with CIBSE TM59, with acoustic constraints influencing some parts of the development.
We quickly built a good rapport with Redrow’s team, external consultants and supply chain, developing an in-depth knowledge of the site. Over the course of the project, we took our lessons learned and applied or further developed these for the next block, tailoring our approaches and recommendations accordingly. We also developed a comprehensive library of thermal bridging values for future use following extensive analysis.
Primarily, we resolved complex overheating challenges by working closely with the acoustician and architect to develop cost-effective, implementable solutions ; including lowering g-values on sensitive facades and identifying exactly which windows could be openable.
By delivering a range of services, we were able to coordinate assessments and associated solutions between ourselves, the design teams and other consultants or suppliers; taking a project-wide view, rather than offering isolated recommendations.
