Taking on climate change: Trowbridge County Hall

Architectural Profiles Limited works with Trowbridge to take on climate change.

Wiltshire County Council's workplace transformation scheme has seen Trowbridge County Hall redeveloped with the specific aim of reducing energy consumption by 40%. "We started by looking at the building envelope first, improving insulation and air-tightness to reduce the energy demand of the building" says engineering consultants WSP project manager Andrew Selway.

Architects Stride Treglown specified the products and systems of Architectural Profiles Limited to provide a retrofit building envelope, which could achieve the dramatic visual impact that they needed whilst also delivering the energy efficiencies the client imposed upon the project.

The system specified was APL Slimwall CPS aluminium Rainscreen system with 20mm wide reveal joints to all sides and all hung on an APL Tritherm support grid. Additional insulation was introduced into the cavity. The Rainscreen and specialist fabrications were all PPC coated in RAL 7012 slate grey.

APL provide a portfolio of products and systems for the whole building envelope, including roofs, for both retrofit refurbishment and new build applications.
