With sustainable and responsible design being at the forefront of modern architecture, it’s no surprise that Gale & Snowden Architects chose Kawneer’s innovative aluminium glazing systems as part of the energy-efficient design to transform St Sidwell’s Point into the UK’s first Passivhaus leisure centre.
Located in Exeter, Devon, this 6,700m2 project centred around the replacement of an ageing leisure centre swimming pool with an eightlane national/county-standard pool and four-lane learner pool, both featuring movable floors.
One considerable façade challenge was to achieve an average 0.8 W/m2 K and a 0.4 m3 /h/m2 @ 50 pascals air leakage which exceeds the current building regulations. For the main glazed areas, two types of curtain walling and three types of doors were specified, as well as high performance windows and brise soleil. All were installed by Kawneer-approved specialist sub-contractor AB Glass on behalf of the main contractor Kier Construction.
Kawneer’s AA®100 HI capped curtain walling was used to create the distinctive building envelope and complement some internal locations, in addition to featuring RT®82 HI windows whose exceptional levels of thermal performance and airtightness helped to achieve the high building specification.
Both products meet rigorous energy efficient design standards and are Passivhaus-certified. These were complemented by Kawneer’s, AA®190 TB external entrance doors, AA®720 standard and AA®720 HI doors internally and AA®130 brise soleil.
Benefits of the Passivhaus design include a 70% saving on energy costs when compared to a current ‘good practice’ leisure centre facility, 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.
The flagship leisure centre in Exeter City Council’s £330 million city centre regeneration masterplan is expected to attract more than 500,000 visitors a year and has been shortlisted for ‘Building Project of the Year’ in the South West Constructing Excellence Awards 2022.
