UK’s first BREEAM ‘Outstanding’ educational building
5th July 2016

The £12.65 million Energy Safety Research Institute (ESRI) at Swansea University become the first education building in the UK to achieve BREEAM “Outstanding” with the help of architectural glazing systems from KAWNEER

The systems were used throughout the 4,500m2 building and comprise AA541 top-hung casement windows, low/medium-duty swing doors and AA100 zone-drained capped curtain walling featuring dressed aluminium feature beams. These mimic steel beams by being glazed into the system and insulated to create horizontal emphasis at varying levels.

They were installed on the brickwork and rainscreen-clad building with cavity and SFS inner wall construction by Kawneer-approved specialist sub-contractor Dudley’s Aluminium for main contractor Bouygues UK.

Ian Standen, associate architect with regular Kawneer specifier Stride Treglown said: “The Kawneer systems are a key feature of the design as the window and curtain walling details became the focus of the Prince’s Foundation for Building Community who were advising the university.”

The ESRI site was part of 40 hectares gifted by BP, one of the university’s major industrial partners. Its funding through Central Government’s UK Research Partnership Investment Fund was contingent on achieving a BREEAM Outstanding rating which made it the first education building to do so.

The design has looked to improve the building’s thermal envelope performance through passive design (reducing air permeability, U-values and g-values) primarily and has subsequently included additional options to reduce energy consumption and to use and recover energy efficiently.

Ian Standen said: “Material sourcing and recyclability were key issues for the design team. As a result the U-values through the frame and press cap details came under scrutiny to match the design criteria and BREEAM credits for the building's energy usage and air permeability requirements.

“By working very closely with the technical team at Kawneer and the sub-contractor providing samples and building mock-ups, agreement was secured for the aesthetic and technical changes presented in using the Kawneer systems, and they work well with the glazed fritted panels and insulated units on the project.”
