Passivhaus Masterclass: Firoz Lalji Global Hub

What does it actually take to deliver Passivhaus at the scale and complexity of a live, occupied city? On 17 November, the day before the UK Passivhaus Conference, this half-day masterclass goes deep into one of the most ambitious non-domestic Passivhaus retrofit projects in the UK: the £100 million transformation of Lincoln's Inn Fields into the Firoz Lalji Global Hub for the London School of Economics, designed by David Chipperfield Architects.

Anticipated to be the largest Passivhaus retrofit building in the UK, the project confronts nearly every constraint that makes non-domestic retrofit hard: a sensitive conservation area location, sandwiched between Grade II* and Grade II listed buildings, a post-war concrete and brick structure, a demanding client sustainability brief, and a simultaneous drive for circular economy principles. The project targets Passivhaus certification, Net Zero, BREEAM Outstanding and WELL Platinum, all on a deep retrofit.

This is not an introductory session. It's a forensic case study for practitioners who want to understand how these outcomes are achieved in practice - the decisions made, the trade-offs navigated, and the technical detail behind the delivery.

A limited number of site tours will be available to in-person Masterclass delegates exclusively. This is a live site - 5 point PPE is required. Site visit tickets will be released closer to the event. Please keep an eye on your email for offical release dates.
