Recording available for ticket holders:Design optimisation at scale: Reducing Costs and Project Risks in Large and Complex Projects

With Allan Smith, Morrison Construction and Caroline Martin, WARM

Kick off the 2025 Masterclass series with a deep dive into design optimisation for large-scale Passivhaus projects. Join experts and PHT Patrons Allan Smith, Morrison Construction and Caroline Martin, WARM as they share strategies for refining early-stage designs, collaborating effectively with supply chains, and avoiding costly over-design. This session will uncover fabric and MEP design strategies with insights from Tier 1 contractors and the UK Certifiers Circle, equipping you with the knowledge to achieve high performance while optimising both cost-efficiency and buildability. Don’t miss this opportunity to gain actionable solutions for delivering ambitious and sustainable Passivhaus projects at scale.

19 February

Recording available for ticket holders: 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!

19 March

Recording available for ticket holders: 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

Recording available for ticket holders: A guide to certification at scale

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

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.

21 May

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

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

This session will examine the potential of an EnerPHit-informed approach for large-scale residential retrofit, highlighting both its challenges and its flexibility across various applications.

Sarah Price from Spruce will open the session by exploring the key drivers behind retrofit in the UK and the pressing challenges in decarbonising our built environment. She will also share insights from Prospect Hill and introduce the Retrofit Hub’s published work on archetype studies, emphasising the importance of collaboration in overcoming the challenges ahead. Sarah will then discuss the adaptability of the EnerPHit standard across different building types.

Lizzy from ECD Architects will share practical insights from their large-scale retrofit projects, focusing on their work retrofitting 3,500 homes in Renfrewshire. She will cover the use of PHPP at scale, from pragmatic fabric-first solutions to full EnerPHit implementation in the most ambitious block, along with effective strategies for communicating design principles to project teams.

Attendees will gain practical insights into EnerPHit and PHPP applications, scalable retrofit strategies, and innovative approaches shaping the future of sustainable building upgrades.

18 June

BOOK Non-domestic EnerPHit 

With Maria-Chiara Piccinelli and Laura Burley, David Chipperfield Architects, Patrick Watson, 3PM and Gwilym Still, Max Fordham

In the final session of the 2025 Masterclass Series, we turn our focus to the EnerPHit retrofit of the London School of Economics’ Firoz Lalji Global Hub (FLGH). Project managers from 3PM will introduce the project’s ambitions, procurement strategy, and delivery context. They’ll be joined by the Passivhaus consultants at Max Fordham and the architects from David Chipperfield Architects to explore the design and detailing approaches behind this ambitious non-domestic retrofit.

We’ll also examine how insights from earlier projects shaped the FLGH retrofit, contributing to its quality and performance. This case study offers a unique opportunity to learn about the challenges and strategies involved in achieving EnerPHit in a dense, urban environment. Don’t miss this deep dive into one of the UK’s most innovative retrofit projects.
