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 series of online tutorials, based on the successful Passivhaus Masterclass: Getting to Net Zero, offers the same depth of knowledge and expertise. Explore issues surrounding net-zero, and gain practical illustrations of what it takes to get to net-zero in both operational and embodied carbon. What can be done at the design stage to achieve the biggest impact? Limited to 30 people, these tutorials offer a chance to learn directly from, and engage with, expert speakers.


This course needs to be part of every architect, engineer and planner's training - and possibly also of all parliamentarians' induction."

Who should attend?

These tutorials will be of interest to anyone who wishes to understand why many low-energy eco-homes are far from net-zero. Architects, designers, and consultants who need to explain to clients how to achieve a zero-carbon building in practice will benefit. 

PHI Credit Renewal Points available:  Delegates will earn PHI credit points towards renewal of their Certified Passivhaus Designer / Consultant qualification once the whole tutorial series is complete.


The knowledge given by the presenters here is really high quality and well pitched; their capacity to provide valuable responses to wide ranging questions and commentary from the audience is impressive and reassuringly informed."

Previous Masterclass attendee - Joanne Murray, Gleeds

Tutorial Programme





2 Sept




Where are we now and what is Passivhaus?

Module 1 introduces the concept of zero carbon and explores the efficiency of our current new builds as a starting point. It includes a short introduction to the Passivhaus standard.

John Palmer, Passivhaus Trust

Block booking available.

9 Sept




What is net-zero?

Module 2 delves deeper into what we need a net zero building to be. How do houses use energy and what are the options for reducing energy demand?

John Palmer, Passivhaus Trust

16 Sept




How does Passivhaus compare to our net-zero definition?

Module 3 compares several common standards, including Passivhaus, against net zero requirements and investigates whether new Passivhaus classes -  Plus and Premium, produce net-zero buildings.

John Palmer, Passivhaus Trust

23 Sept




Setting the challenge into context

Module 4 examines net zero from the alternative perspective of deriving how much renewable energy might be available for homes in the future to indicate to what level we need to be building and retrofitting to.  Then compares this to the volume and type of UK housing stock to describe the scale of the challenge of getting to net zero.  Draws all the previous operational net zero modules together to a mid-course conclusion.

John Palmer, Passivhaus Trust

30 Sept




Introduction to definitions and methodology

Module 5 gives a brief overview of what is included in embodied carbon analysis, methodology and datasets. This session also discusses key watch points when pulling materials data from BIM models and offers a brief discussion on the inclusion of MEP in the embodied carbon model.

Materials: timber and concrete

Module 6 starts to examine materials – what should we be using and in what way? Based on global consumption, embodied impact, and contribution to life-cycle carbon, what are the justifications for using three key materials: timber, concrete and steel? This session includes a more detailed look at the carbon profile of timber and concrete and key technical considerations in use, specification and procurement.

Kirsten Henson, KLH Sustainability

14 Oct




Materials: steel - and top tips for designing low-embodied buildings  

Module 7 follows on from the previous session to include a detailed look at the carbon profile of steel and the key technical considerations in use, specification and procurement. The session concludes with a summary of top tips for designing low carbon buildings using real projects to highlight key considerations and potential impact.


Kirsten Henson, KLH Sustainability

21 Oct



PH Ribbon demo

Module 8 is a demonstration of the integrated PH Ribbon which allows instant embodied energy calculations for a building modelled in the Passivhaus Planning Package (PHPP), presented by the creator of the tool, Tim Martel.

Tim Martel, Optimal Retrofit

28 Oct


Final workshop

Review and interactive workshop

This double-length session includes both a review of previous sessions, and a final case study workshop. Delegates will be asked to take part, contribute design ideas and review options for improvement before being presented with what actually happened on the ground.
