Passivhaus Masterclass: Getting to Net Zero

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.

11:00 - 12:30

Passivhaus and Net Zero (John Palmer, Passivhaus Trust)

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.

Net Zero Embodied (Speaker tbc)

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.

PHribbon Demo (Speaker tbc)

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
