EQUITONE [natura] and [textura] from Marley Eternit have helped create the award-winning BREEAM 'Excellent,' research facility at Swansea University.
The Institute of Life Science building (Phase 2), won the BREEAM Wales Award thanks, in part, to Marley Eternit's EQUITONE architectural fibre cement facade material. The BREEAM awards recognise only those construction projects that demonstrate excellent environmental aspects in their specification, design and construction. An EQUITONE fibre cement facade met this criteria because it can contribute to an A+ rating as defined in the BRE Green Guide to Specification based on generic rating for autoclaved fibre cement single sheet.
Powell Dobson Architects also specified the material because of its aesthetics, which addressed the challenging brief: to deliver a sustainable building whilst working within the constraints of an environment which is suitable for clinical research and trials facilities. Barrie Jones of Powell Dobson Architects explains: "We specified EQUITONE materials because the contrasting textures and array of colours on offer allowed us to create a visually striking aesthetic. We were delighted to win the BREEAM award and the use of Marley Eternits facade materials played a key role as it is able to achieve an A+ rating as defined in the BRE Green Guide to Specification.
Equitone natura in Charcoal and Cool Grey was the predominant material used on the facade because it created a striking visual appearance. Equitone textura in Sand and Egyptian Blue was chosen for recessed elements within the facade and a number of feature walls. The Equitone facade panels were rivet fixed to a metal framing system at upper levels of the building. Secret fix was used for panels at the lower level to accentuate the sheer, architectural facade that the designers felt suited this high-tech research facility. 100mm of PIR board was used to insulate the walls, which achieved a U-value of 1.1 W/m²K.
