Western Power Distribution depot
A two-story, BREEAM Outstanding steel-framed depot.

Highlights
- Achieved a BREEAM Outstanding rating of 91.9%, post completion, making it the world’s highest rated BREEAM project at the time.
- WPD Spilsby has also been assessed by the Considerate Constructors Scheme which ranked it in the top 5% of construction sites assessed in the UK.
- Achieved a top environmental award with an Energy Performance Rating of -2, which means it’s more efficient than a fully carbon neutral building.
- Using standardised specification methods developed as a result of working on nearly 40 depots for WPD has enabled B3 Architects to create a library of specific BIM component families and design processes.
Approaches Used
- A ‘fabric first’ approach to provide excellent U-value and airtightness.
- A long-lasting, air-tight envelope to help reduce the operating costs of the building includes Trisomet® composite panels for the roof and walls, with its energy efficient liner. As well as being robust, quick to fit and cost-effective, the panels have a PIR core which provides the desired high level of insulation which contributes to the BREEAM Outstanding rating.
- The panel system features Colorcoat® High Reflect pre-finished steel liner which is designed to provide at least 85% reflectance.
- Both the Colorcoat® pre-finished steel products used and the Trisomet® composite panels are certified ‘Very Good’ to BES 6001, obtaining the maximum number of credits available in the Responsible Sourcing of Materials sections of BREEAM for materials that are not being re-used.
- Innovative Active heat / energy generation. Data monitoring over 2 years.
