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

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 will explore 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 class will also explain 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.

John PalmerJohn Palmer is Research and Policy Director at the Passivhaus Trust, where he recently authored Passivhaus: the route to Zero Carbon?, exploring how to ensure zero carbon targets result in zero emission buildings. John is a certified Passivhaus consultant, SAP Assessor, systems engineer and experienced project manager.  In practice he works with a team of engineers using fabric-first building physics principles to design and build living spaces that are comfortable, healthy, energy efficient and easy to maintain. Prior to entering the construction sector, John spent 16 years as an engineering officer in the Royal Navy, which included three years at the Ministry of Defence. 


Kirsten HensonKirsten Henson is Director of KLH Sustainability, a sustainable construction consultancy. A a guest lecturer in Engineering at several universities, Kirsten also provides specialist sustainability input to the International Olympic Committee as well as Independent Design Review Panels including HS2 and Harlow and Gilston Garden Town. Kirsten’s research-based approach, supported by practical knowledge and an extensive network of professionals, often opens new avenues of thought. She recently completed research on the sustainable use of aggregates which has informed the new BREEAM 2018 Wst 02 criteria, considering aspects such as regional availability, social impacts of transportation and carbon footprint.



Tim MartelTim Martel is a freelance Chartered Architectural Technologist, Passivhaus Designer and Retrofit Coordinator with a background in calculations through commercial R&D. He is currently a tutor for the AECB for the Economics and Building Physics/Case studies modules. Tim has been a Passivhaus Designer for 6 years, working on new houses and the Passivhaus Garway community centre. He is an expert of PHPP and the advanced variants feature and has written the PHribbon tool to make it faster. He has worked extensively with the AECB using the Omnisense monitoring system which is unique in being able to measure moisture content inside walls as well as temperature and humidity. He used this to prepare large amounts of data for the Case Studies and Economics modules of the Carbonlite Retrofit course.



11:00 - 12:30

Passivhaus and Net Zero (John Palmer)

This session will look at how to achieve a real net-zero building.  It will compare Passivhaus with the UK Building Regulations standard and explain why the Passivhaus approach offers a better mechanism for achieving net-zero.  It will cover the use of renewables and how both Passivhaus Plus and Passivhaus Premium relate to net-zero.  This session will draw on the research paper from the Passivhaus Trust.

12:30 - 13:30

13:30 - 15:00

Net Zero Embodied (Kirsten Henson)

This session will look at the way in which the embodied energy of a building can be assessed.  It will focus on which design decisions have the biggest impact on embodied energy and also provide some context to explain that the materials/equipment critical to Passivhaus (e.g. insulation, glazing and MVHR) account for a very small element of the embodied energy.

15:00 - 15:30

15:30 - 16:00

PHribbon Demo (Tim Martel)

This session introduces the functions of the PHribbon tool  developed to work with PHPP (version 9.1, 9.3 or 9.6). The toolbar in Excel is modular for ease of use and flexibility. 


16:00 - 17:00

Workshop session

This session will allow delegates to understand the overall context of the earlier sessions by providing models for both operational and embodied energy and allow the design criteria (materials, glazing, services, orientation etc) to be varied and see the impact on both operational and embodied energy
