Large scale residential case studies

With Gwilym Still, Max Fordham, Sam Godfrey, Eric Wright Construction and Alison Haigh, Buttress Architects

Join us for the second webinar in our 2025 Masterclass series as we dive into two transformative Passivhaus projects in Manchester: the completed Greenhaus and the in-progress Willohaus. Learn how PHPP was leveraged as a powerful value engineering (VE) tool, integrating contractor input to optimise design choices. Explore the evolution of technical details across multiple projects, tackling key challenges like steel frame systems (SFS), standardisation, and mitigating thermal bridges in large-scale developments.

Discover insights from post-occupancy evaluation (POE) data, revealing how designs perform in real-world operation. This session offers a unique opportunity to learn from real case studies, gain actionable strategies, and stay at the forefront of Passivhaus and net-zero design. Don’t miss this essential webinar for anyone involved in sustainable development at scale!

BOOK Large-scale non-domestic case study 

With Jamie Gregory, AHR and John Peden, Fife Council

Gain practical knowledge and firsthand experiences from delivering one of Europe’s largest Passivhaus developments as we dive into Dunfermline Learning Campus.

Jamie Gregory will explore the process of using PHPP and other Passivhaus tools to optimise building performance through the various RIBA stages - while delivering great architecture, reducing risk, and maximising value. Drawing on his experience with one of the largest Passivhaus projects in Europe, Jamie will share key insights into how data-driven design decisions can enhance energy efficiency, comfort, and long-term project success.

He will be joined by John Peden, lead architect at Fife Council, who will present a “lessons learned” session from the Scottish Passivhaus schools delivery programme. John will highlight how Fife Council is applying these insights to future projects, offering valuable takeaways for local authorities and project teams.

23 April

BOOK A guide to certification at scale

With Tomás O’Leary, MosArt and Sally Godber, WARM 

Join us for a deep dive into the challenges and solutions for certifying large-scale Passivhaus developments, led by two of the UK and Ireland’s most experienced Certifiers. Learn from real-world examples, including Cairn Housing’s ambitious delivery of 3,000 homes in Ireland and the Dunfermline Learning Campus, one of the UK's largest Passivhaus developments. This webinar offers practical insights into managing certification processes, overcoming hurdles, and ensuring quality at scale.

BOOK Retrofit at scale (estate wide approaches to residential retrofit)

With Dr Sarah Price, Spruce and Lizzy Westmacott, ECD Architects

Explore the potential of EnerPHit for high-rise residential buildings. Gain practical insights into EnerPHit applications, scalable retrofit strategies, and innovative approaches shaping the future of sustainable building upgrades.

Sarah Price will delve into the adaptability of EnerPHit, highlighting its relevance across different building types whilst providing an update on the exciting progress being made with the new Retrofit Scheme. Sarah will also touch on the Retrofit Hub's published work on archetypes, showcasing one approach to tackling retrofit at scale and providing a broader context for achieving impactful results in the built environment.

Lizzy from ECD Architects will share insights from their large-scale retrofit projects, focusing on their work retrofitting 3,500 homes in Renfrewshire. The session will include a discussion on using PHPP at scale, pragmatic solutions and effectively communicating design principles to the project team.

18 June

BOOK Non-domestic EnerPHit 

In this final session of the 2025 Masterclass Series, we’ll explore the EnerPHit retrofit of the London School of Economics’ Firoz Lalji Global Hub (FLGH). Led by the Passivhaus and MEP consultants at Max Fordham and the project architects at David Chipperfield Architects, this case study will provide an in-depth look at the design and detailing process for this innovative non-domestic retrofit. The session will also highlight how lessons learned from previous projects were integrated into the FLGH, contributing to its success. Don’t miss this opportunity to delve into the challenges and solutions for achieving EnerPHit standards in a complex urban retrofit project.
