Kawneer Glazing Systems to feature on world's first Passivhaus Leisure Centre
Kawneer glazing systems to feature on world's first Passivhaus leisure centre
The complete portfolio of Kawneer products will be used at St Sidwell's Point in Devon.
Work is expected to start shortly on the installation, on the world's first Passivhaus leisure centre, of architectural glazing systems by leading UK manufacturer Kawneer.
The systems - two types of curtain walling, three types of doors, windows and brise soleil - will be installed by Kawneer-approved specialist sub-contractor AB Glass for main contractor Kier at St Sidwell's Point in Exeter.
The 4,850m2 project will replace an ageing swimming pool with an eight-lane national/county-standard pool and four-lane learner pool, both with movable floors, together with dry sports facilities including gym, café and crèche, and health and spa amenities.
Benefits of the Passivhaus design include a 70% saving on energy costs when compared to a current good practice pool, a 50% reduction in water use, outstanding internal water and air quality, excellent daylight levels and lower maintenance costs due to a high-quality building fabric.
Step up Kawneer's Passivhaus-certified AA®100 capped curtain walling, which will be used around the building envelope and some locations internally, and RT®82HI windows which feature exceptional levels of thermal performance and airtightness, partly due to larger-than-normal thermal breaks.
These Passivhaus-certified products will be installed by AB Glass alongside Kawneer's AA®100 FR and AA®720 FR fire-rated curtain walling and doors as internal screens, AA®190 TB external entrance doors, AA®720 standard and AA®720 HI doors internally and externally, and AA®130 brise soleil.
The flagship in Exeter City Council's £330 million regenerating city centre masterplan, which also includes housing, offices, restaurants and retail, is expected to open to the public, alongside a new bus station, in the spring of 2021, and attract more than 500,000 visits a year.
Exeter City Council and Passivhaus designers Gale & Snowden architects have delivered several Passivhaus multi-unit housing schemes but this is the first commercial Passivhaus development they have embarked on together.
The hybrid construction comprises an in-situ concrete frame with aerated concrete blockwork infill and mineral wool batts on an insulated in-situ ground floor slab. The design also features a metal standing seam roof on CLT (Cross Laminated Timber) and glulam beam structure and a liquid-applied warm roof on a steel frame structure.
The Passivhaus Institute is acting as Passivhaus certifier and modelling the design in a bespoke multi-zone PHPP (Passive House Planning Package). As such, the energy performance figures are different to standard Passivhaus calculations due to the high pool and changing area temperatures.
Alan Brayley, managing director of AB Glass, who will have a team of up to 30 on the project for an estimated 30 weeks, said: "We are thrilled to have been awarded this contract. This is an innovative project that we are very excited to be involved in. The environmental credentials of this building are such that we believe some of the standards and skills we will be implementing here will be in high demand in the future as many more buildings look to emulate what we see here."
Kawneer systems help herald a gateway to a unique building
Manufacturer’s aluminium glazing systems used again at Bournemouth University
Frequent Kawneer specifiers Atkins has used the manufacturer’s architectural aluminium glazing systems again, on a unique building which forms a new £27 million gateway to a leading UK university.
Kawneer’s AA®100 zone-drained and capped curtain walling forms triangular screens some 25m.
wide and 15m high for the main atrium at Bournemouth University’s 5,000m2 Poole Gateway Building, while Kawneer’s thermally-superior AA®720 entrance doors were used throughout the building and its AA®190 TB automatic sliding door was used at the campus side entrance lobby.
In addition, Kawneer’s AA®541 fixed-light windows were used to create openings within both the rainscreen and masonry facades while thermally-broken AA®543 tilturn windows were used alongside aluminium spandrel panels as insertions to the curtain walling.
Kirsty Pesticcio, senior architect at Atkins, said: “The glazed elements have a significant impact on the building and the Kawneer products interfaced really well with the masonry and rainscreen façade.
“The triangulated gateway form was very complex in nature so we had to ensure fixings were angled with precision to tie into the structural members. Kawneer-approved installer Leay were engaged early within the design process to ensure the developing design met both our design concept and technical constraints of the products chosen.”
The building was targeting a BREEAM “Excellent” score so upper BRE Green Guide ratings for material specification, aligned with budgets, was important.
The Poole Gateway building is a state-of-the-art combined technical facility for the university’s faculties of Science and Technology and Media and Communication, the latter of which houses the UK’s only recognised Centre for Excellence in Media Practice.
The two-year build by main contractor Willmott Dixon comprises a steel frame, SFS infill and composite concrete decked floors. Although the building is primarily divided by internal stud partitions, there are many technical studio spaces which had to be designed and installed as a ‘room in room’ construction using timber frames.
Specialist sub-contractor Leay had a team of up to six on site for three winter months.
Leay’s business development manager Mike Watts said: “The main curtain wall screens are essentially large triangles. The transom locations were staggered in design in an attempt to prevent hard lines being established in the overall design.
“The transoms were set out by us to keep glass specification the same thickness on the project and also to optimise the material on the project efficiently to keep wastage down and therefore cost.
“The project was also designed to limit the amount of intermediate steelwork to make the atrium feel as open plan as possible as well as to dead load the full screen down onto the ground-floor slab.
“We proposed the use of Kawneer products on this scheme from the outset as we knew they would represent the best value for money and also achieve the structural requirements of the scheme. Working alongside the architect from an early stage, we were able to quickly assist with mullion sizings to allow setting out to be established and avoid potential clashes at a very early stage.”
Atkins’ brief was to deliver a new gateway building on the eastern edge of the university’s Talbot Campus which sits just inside the border between Bournemouth and Poole and would be predominantly used by students from the two faculties, providing a range of high-quality technical facilities to support undergraduate and postgraduate courses as well as research.
Kirsty Pesticcio said: “We believe the client is delighted with the overall design and how it meets the original brief of a gateway building to their campus.”
NESTA (National Endowment for Science Technology and Art) said: “Almost half of all graduates from specialist VFX [visual effects] courses who gained employment in the industry had graduated from Bournemouth University”. Graduates have worked on Hollywood blockbusters such as Lord of the Rings, Gladiator, Gravity, Star Wars, Madagascar and Interstellar, which won an Oscar in 2015.
The Poole Gateway building is one of three at Bournemouth University which feature Kawneer systems.
They have also been used on a £40 million new home for the Faculty of Health and Social Sciences. Again designed by Atkins, the Bournemouth Gateway Building features Kawneer’s AA®100 curtain walling with feature face caps on tall atrium screens along with AA®720 window vents and entrance doors and AA®190 TB doors. The Kawneer systems here were installed by fellow Kawneer-approved dealer Aluminium Sashes for main contractor Kier. The Bournemouth Gateway Building is due to open in September 2020.
Kawneer systems were also used on the original £22 million BREEAM “Excellent” Fusion building which features Kawneer’s AA®100 zone-drained curtain walling, AA®541 top-hung casement windows, AA®545 low/medium duty swing doors and series 190 doors. These were installed by approved dealer AB Glass for Willmott Dixon to a BDP design.
