Passivhaus Masterclass: Getting to Net Zero

Getting to Net Zero - reducing in-use and embodied carbon


Due to the coronavirus lockdown, this Masterclass has now transitioned to an online model. Watch and learn through on-demand videos in your own time, then join a live online afternoon workshop on 28 April to consolidate, discuss and put into practice what you've learned.


The increased focus on the Climate Emergency has led to a stream of declarations to achieve Net Zero. But what does that actually mean to the built environment?  Do we really know how to design and deliver a true net-zero building?  This masterclass explores the issues around net zero, providing practical illustrations of what it takes to achieve both net-zero operational energy and net-zero embodied energy and highlighting what can be done at design stage to achieve the biggest impact. The course also explains how Passivhaus Classic, Plus and Premium can be used to support a net-zero design.

This masterclass will be of interest to architects and consultants who want to be able to explain to clients how to achieve a zero carbon building in practice and who wish to understand why many low-energy eco-homes are actually far from net zero.
