TUTORIALS: Getting to Net Zero

Location: Online Cost: PHT member: £20-150+VAT Non-member:£25-£225+VAT

Net Zero Carbon Tutorials

While we adjust to the Corona Lockdown, we must continue tackling the Climate Emergency and maintain the momentum which led to a stream of declarations to achieve Net-Zero. But what does that mean to the built environment? Do we know how to design and deliver a true net-zero building?

This new 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.


The Passivhaus masterclass was a great way to understand the route to zero carbon and balancing the challenges we face in achieving a true zero carbon in construction and in use."

Previous Masterclass attendee James Turner, Mikhail Riches


Who should attend?

These tutorials will be of interest to anyone (particularly those in furlough) 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 can earn 6 renewal points once the whole tutorial series is complete.


I use the lessons learnt from the Zero Carbon Masterclass every day and we have now started incorporating many of the things discussed as standard - super helpful."

Tutorial Programme





29 April




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.

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

13 May 




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

20 May 




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.

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

10 June 




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

17 June 




PH Ribbon Demo

Demonstration of the integrated PH Ribbon which allows instant embodied energy calculations for a building modelled in the Passivhaus Planning Package (PHPP.)

Tim Martel, Optimal Retrofit

24 June 


Final Workshop


Interactive workshop

Recap the whole tutorial series & pull all the strands together in an hour long session. Implement learnings to a real case study & get it to zero carbon.  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.

The impressive research work and presentation on the performance gap between the present Part L Building Regs and actual reality was crystal clear. This knowledge will give us great backup in trying to persuade the industry to build better."
