HEATING, VENTILATION & AIR CONDITIONING


Riverside Primary is a Passivhaus building, which provides a high level of occupant comfort all year round using very little energy for heating, hot water and cooling


SCHOOL OF THOUGHT


Heatrae Sadia water heaters from Baxi have been specified for Scotland’s first Passivhaus-certified Primary School, enabling Perth & Kinross Council to enhance education provision while taking steps closer to its Net Zero carbon ambitions


R


iverside Primary, Scotland’s first Passivhaus- certified Primary School, is a multi-


million-pound building which brings together North Muirton and Balhousie primary schools, providing modern learning space for 500 children with additional provision for a nursery and additional support needs (ASN). The project is part of Perth & Kinross Council’s


ongoing capital programme of school upgrades and improvements through hub East Central Scotland Limited (hubco) which is designed to enhance the environment for learning and teaching across the area.


YEAR ROUND COMFORT Passivhaus buildings provide a high level of occupant comfort all year round using very little energy for heating, hot water and cooling. They are energy efficient, environmentally friendly and economical to run. Instrumental in forming the energy strategy


for the new school building were BakerHicks Motherwell, appointed by Perth & Kinross Council, to provide mechanical and electrical design services for principal contractor Robertson Tayside. David Coulter, associate engineer and certified


Passivhaus designer at BakerHicks, said: “The hot water strategy was one of the main challenges when designing the system as we needed to avoid large scale energy usage. We wanted to explore using all-electric point-of-use solutions that would only generate energy when required, for example during break or lunch times. So we asked Baxi for help with the solution.” It was identified that Heatrae Sadia water


heaters – including Multipoint, Multipoint Eco, Hotflo, Aquaheat, as well as a Megaflo Eco

cylinder – would efficiently meet the hot water demands across the building.


EFFICIENT WATER HEATING BakerHicks had specified Heatrae Sadia products before and was familiar with their reputation for high-quality, robust performance. “A key benefit of these water heaters is that


the units are sized, thereby providing more flexibility to meet the required volume. But equally importantly is the excellent technical and aftersales support that we know we can expect from the Baxi team – and which proved invaluable on this project,” explained Coulter. All certified Passivhaus


buildings must undergo a rigorous quality assurance compliance process that includes tests to ensure the targets are met. Certification is only issued by the independent Passivhaus certifier, in this instance WARM, if the defined criteria are achieved. Coulter said: “We needed


to supply detailed calculations and evidence relating to the energy values of the selected technologies. And this is where we really relied on Baxi for support. They were great, working


closely with us to provide all the information required for certification and ready to help at every stage of the project.”


MEETING NET ZERO With Passivhaus certification now successfully achieved, Perth & Kinross Council has achieved its commitment to enhance education provision for children north of Perth and taken a step closer to its Net Zero carbon ambitions. “The very low heat losses of our Heatrae Sadia


products were a key component in the overall project. We are extremely proud to have played a part in this ground-breaking Passivhaus primary school,” said Baxi’s Stephen Lynch.
