Kawneer's curtain wall plays a key role at the National Automotive Innovation Centre.
Kawneer glazing systems showcase leading-edge automotive research
Kawneer's curtain wall plays a key role at the National Automotive Innovation Centre.
Aluminium curtain walling by leading UK manufacturer Kawneer, has helped an award-winning and cutting-edge combination of industry and academia achieve a BREEAM "Excellent" rating.
The National Automotive Innovation Centre (NAIC), at the University of Warwick, is one of the largest centres of its kind in Europe, and a partnership between WMG (University of Warwick), Jaguar Land Rover and Tata Motors UK and features Kawneer's AA®110 mullion-drained curtain wall.
The curtain wall system with 65mm sightlines, occasional fritting and in places a translucent inner layer, has been used at triple height on the entrance façade, as ribbon glazing on the ground and third floors, and as roof lights underneath the over-sailing roof.
Delivered between January 2015 and August 2018, using BIM by main contractor Balfour Beatty, the project was the first live construction site to trial BIM-based meeting space and such was the success of BIMspace, a next-generation facility camouflaged in a site cabin, it won BIM Initiative of the Year at the Building Awards.
Designed to provide a national focus for expertise in automotive R&D, it accommodates up to 1,000 technologists, academics, designers, students and engineers, with the aim of fostering collaboration to develop and utilise new breakthrough vehicle technology.
The L-shaped building is four storeys high and is 33,000m2, with a full-height atrium and a glulam and steel composite diaphragm roof. The Kawneer glazing, which plays a key role in the project by allowing natural light to penetrate the deep-plan building and providing views in as well as out, was divided into several equally key components.
At the entrance façade, the quadruple-height Kawneer curtain walling clearly demarcates the public entrance area to the building, allowing for views in and out from the main entrance space/exhibition, while triple-height glazing mirrors the glazed wall to the engineering hall directly inside the building. Glazing in this area is bolted back to full-height rectangular steel sections and interfaces with revolving doors at ground level.
The ground-floor ribbon glazing linking into the entrance facade glazing, wraps around the main public front to the building, providing a fully-glazed facade to the cafe as well as the student projects space.
Generally single storey in height with elements of double storey glazing at key points along its length, some panes of glass are fritted at 60% grey to provide shading, and in more commercially sensitive areas and service areas, an interlayer was added to make the panels translucent. Incorporated into the Kawneer system are a series of glass louvres controlled by an actuator providing smoke ventilation in case of a fire in the exhibition area.
On the majority of the third floor, a ribbon of capped curtain walling provides a visual break between the timber cladding panels and the glulam roof which appears to float over the building, while allowing the third-floor office spaces to take advantage of panoramic views into the surrounding landscape. Here, the Kawneer curtain walling also deals with the deflection of the dramatic glulam roof which can deflect by up to 50mm.
The Kawneer capped curtain wall also forms punched windows in the brickwork and timber cladding panels, allowing natural light into, and views out of, offices, key working spaces and stairwells. Here, the system allows for deflection of the timber cladding panels, with glass louvres incorporated into the Kawneer system in the stairwells to provide smoke ventilation in case of fire.
Finally, the Kawneer curtain wall forms roof lights in the design studios, providing north lights in a series of single and double-height design spaces.
Glazing mullions were positioned to reflect the rhythm of the anodised aluminium mesh cladding around the first and second storeys, and the curtain walling was powder coated to match the colour of the structural steel elements of the building.
Environmental sustainability influenced the choice of materials and construction methods, including the in-situ concrete frame and glulam roof structure which was renewably sourced with low embodied energy. The roof also houses 1,900m2 of photovoltaic panels to reduce the energy load.
Cullinan Studio, who were the architects, said: "We needed to meet green guide ratings for our BREEAM assessment and the Kawneer curtain walling helped us achieve this.
"The materials - anodised aluminium, glass, glazed brickwork and engineered timber - are enduring and can be built with a high degree of precision - all project excellence in engineering.
"The silicone jointing along the ground-floor glazing and entrance facade helped create the illusion of a seamlessly glazed wall while simultaneously dealing with the movement of the building. In order to achieve the double and quadruple-height areas of glazing, the system was fixed back to steel sections."

Kawneer systems help rejuvenate the UK’s oldest business school
Kawneer’s market-leading curtain wall, window and door products feature on University House at the University of Birmingham.
Architectural glazing systems by leading UK manufacturer Kawneer were specifically selected for a £18.5 million extension to the UK’s oldest business school for their ability to meet the building’s design aesthetic and high-performance requirements.
Multiple Kawneer products, including two curtain wall systems, two door products and three window variations, were used by main contractor Morgan Sindall Construction for the University House project, a gateway to the University of Birmingham’s city centre campus.
The University House building is steeped in history and heritage as it was originally established as the School of Commerce in 1902. The Grade II listed Business School building was formerly the first halls of residence for female students and was converted to its current use in the 1960s.
The new 3,000m2 extension features Kawneer’s AA®110 and AA®100 mullion-drained curtain wall systems with capped and capless mullions as well as AA®100 zone-drained fully-capped curtain wall. The AA®100 system, with 50mm sightlines, was used in all areas with the exception of two full-height curtain wall screens which featured on the building’s ‘social space’ characteristic that utilised the AA®110 system with 65mm sightlines.
In addition, Kawneer’s series 350 and AA®720 HI thermally-superior entrance doors were used alongside AA®720 HI windows as fixed lights, side-hung open-in inserts and electrically-operated bottom-hung open-in inserts.
Glancy Nicholls Architects were appointed to design a building that provided a cellular and multi-occupancy space for the school’s academic staff, with student break-out spaces along with refurbished professional services, staff offices and enhanced café and catering facilities.
There were a number of challenges on site with available space as it was situated adjacent to the original building, surrounded on two sides by heavy perimeter landscaping/trees and bordered by a formal lawn. Glancy Nicholls designed and developed a series of offices located around a central atrium space, with connections back into the existing building at ground and first-floor levels.
Glancy Nicholls director Simon Jesson said: “The Kawneer systems were selected by the sub-contractor to meet the stringent thermal performance requirements along with the high-quality detailing required by the planners.
“To maximise the daylighting the elevation incorporated large windows but also required user control of the ventilation as well as glare control. The system was able to provide the aesthetic requirements for incorporating silicone jointing to minimise the impact of the frame on the proportions of the windows.
“The relationship to the brickwork cladding, the stone and the glass-to-glass corners on the bay windows was managed efficiently with the necessary trims and recessed details to maintain a clean-looking façade.”
The Kawneer glazing systems were installed by specialist sub-contractor and Kawneer dealer Duplus Architectural Systems.
Simon Jesson added: “Planning sensitivities were considerable with the massing of the building required to be sited adjacent to the listed building without dominating the elevation, but being contemporary with high-quality materials, in this case multi bricks and an Indiana limestone cladding system, complemented by the anodised bronze high-performance windows.
“The south elevation was a considerable challenge, with projecting bay windows that allowed daylight and a view of the formal lawn but were screened to adjacent landowners. The triple-glazed glass-to-glass corner projecting past the line of the cladding was a key design feature.”
He concluded: “The client is really pleased by the overall look and feel of the building. The elevations are a contemporary aesthetic which complement the existing listed building.”
