Project Focus BESPOKE SYSTEM FROM KALZIP FOR PASSIVHAUS SCHOOL Abespoke roofing system from Kalzip has been chosen for Scotland’s first Passivhaus School in North Muirton, Scotland. The system was chosen for its incredible sustainability benefits, along with its speed of installation. The new £16.5 million school will be built on the site of the current North Muirton Primary School and will have a capacity for 500 pupils, incorporating a nursery and additional support needs (ASN) provision each with their own dedicated outdoor space. The roofing system was developed by Kalzip alongside architects Architype and Curtis Moore contractors to achieve these demanding standards through Kalzip’s thermal modelling and demonstration of the life cycle of Kalzip’s products, along with the sustainability of the system, which were all achieved. The Passivhaus Standard represents an inclusive approach to design, aiming to create buildings that offer exceptional comfort to occupants while minimizing energy usage for heating and cooling purposes. The forthcoming school project is committed to attaining this standard, which will lead to a substantial decrease of 60-80% in energy consumption. As a result, this reduction will contribute to carbon emissions reduction while simultaneously lowering operational and maintenance expenses. Achieving the Passivhaus Standard entails a comprehensive focus on efficient design and construction practices, as well as careful material selection to ensure optimal building efficiency throughout every phase of the project. A Kalzip Built Up Insulated System with structural deck roof was installed on the school with a U-value of 0.10W/m 2 K to achieve Passivhaus Artist’s impression: North Muirton Primary School. “The Kalzip system is ideal where speed of installation on a project is of utmost importance” standards. This system was a bespoke solution for the school, but the main product is used predominantly for new build construction, although it can also be used as a refurbishment solution in the event of a failed roof, or when building improvements are being considered. The Kalzip system is ideal where speed of installation on a project is of utmost importance. A non-fragile Kalzip liner sheet can be quickly installed to provide a temporary weather cover to allow other trades to work below. The remainder of the roofing components can then be installed without affecting the critical path of the construction programme. The architectural plans for the building were meticulously crafted following extensive consultation with the local community. They will offer top-notch educational facilities, including 16 classrooms, with an additional two classrooms reserved for potential future school expansion. The building will also house provisions for Additional Support Needs (ASN), group study rooms, a versatile multi-use hall, a kitchen area, staff amenities, a multi-use games area (MUGA) pitch for both school and community use, and a nursery facility that will operate throughout 50 weeks each year. There was some complexity to the project in which Kalzip provided assistance and early collaboration was key for this project, with the design challenges that needed to be achieved while also working to Passivhaus standards. There was also some difficulty in focusing on every element from structure to the individual fixings as each aspect required precise U-value calculations, with no room for error, in which Kalzip’s technical expertise was crucial for the success of the project. Councillor Caroline Shiers, Lifelong Learning Convener, Perth & Kinross Council, said: “This is a very exciting development as part of the Council’s work to transform the school estate in Perth and Kinross. We aim through this project to both enhance education provision for children in the north of Perth, but also support a more environmentally friendly learning and teaching environment – as one of the first Passivhaus primary schools to be built in Scotland." North Muirton also meets the ambitions of Perth & Kinross Council as they work towards a Zero Carbon agenda, as the Council’s Interim Chief Executive, Barbara Renton, explained: “We want to ensure that our buildings, from offices to schools, are energy efficient, cost-effective to run and maintain, and contribute to an improved environment. Using the Passivhaus Standard for the new primary school in North Perth enables us to address all three areas at once through carbon reduction being built into the design and construction process.” Contact Kalzip Kalzip www.kalzip.com/en/ 28 TC FEBRUARY <strong>2024</strong>
