World’s largest Passivhaus school cuts energy use in half in first year

New figures from BAM UK & Ireland show the world’s largest Passivhaus school has cut energy bills by £433,392 and reduced energy consumption by 48% in its first year of operation, despite freezing temperatures and snow across Scotland.

Built for Fife Council, the new Passivhaus-certified building opened in Autumn 2024, bringing together 2,700 students from two high schools, Woodmill and St Columba’s, and replacing older school buildings. The two schools are linked by a central hub designed to foster collaboration, innovation and community use, supporting better outcomes for all.

Under Scottish Learning Estate Investment Programme (LEIP) funding requirements, the first-year energy performance of the building is critical, with funding contingent on meeting strict in-use energy targets.

Under a three-year facilities management contract with Fife Council, BAM UK & Ireland is delivering real-time monitoring which shows the building is far exceeding the required targets, setting a new benchmark for sustainable school design in the UK and helping to reduce energy costs.

Jim Ward, regional director at BAM UK & Ireland, said: “These figures prove without doubt that Passivhaus works at scale. Because we built and now operate the school, we can see exactly how it performs in real conditions including during periods of extreme cold. The building is operating around 20% better than its original energy performance target, while delivering significant financial benefits, which is a real accomplishment and sets a new standard.

“Building like this is not without its challenges - Passivhaus schemes demand a different approach from the industry from conception to delivery. They introduce a new level of accountability where every system and every detail has to perform exactly as intended.”

Councillor Cara Hilton, Fife Council’s education spokesperson, is delighted Dunfermline Learning Campus is living up to expectation: “The Passivhaus certification continues to be a fantastic achievement for Dunfermline Learning Campus. It highlights our commitment to sustainability and providing high-quality learning environments for our students.”

BAM has managed the project across its full lifecycle, from design and construction to post-occupancy monitoring and management. A digital twin and building management system collect data from 150 metering points every 30 minutes, enabling live performance monitoring and allowing BAM to assess factors such as temperature and air quality in real time, making continuous changes to improve efficiency and user comfort.

Key highlights from the first year:



  • The campus is operating 20% better than original energy performance target
  • Extensive airtightness testing, achieving 0.4 air changes per hour — well beyond regulatory requirements and even beyond the Passivhaus requirements of 0.6 changes per hour
  • Real-time monitoring using a digital twin allow BAM’s FM team to manage energy and comfort levels within the building.
