Passivhaus Series: 1. Fundamentals of Passivhaus - London

Event one of a series of four half-day Passivhaus events held in conjunction with AECB CarbonLite and Pollard Thomas Edwards.

The Green RegisterAECB CarbonLite and Pollard Thomas Edwards are pleased to be working together to provide four half-day technical sessions in London on the Passivhaus principles.

Although the full Passivhaus training is a fantastic way to gain an in depth understanding of all aspects of Passivhaus design, some construction professionals may not have the time or resources to be able to attend the typical Passivhaus two week course.

These afternoon sessions offer insight into all the main principles i.e. what makes a good low energy, comfortable building based on the Passivhaus standard. The training is ideal for architects and other design professionals as the focus in these courses is on design principles.

Each of the four sessions will be run by experts in the field who are actually successfully designing/ building Passivhaus in UK. Amongst others, Bill Butcher, Alan Clarke, Sally Godber, Nick Grant, Eric Parks, Marine Sanchez, Mark Siddall; and Passivhaus Certifiers Will South, Mike Roe and Peter Warm. Assisted by Passivhaus Designers Tom Dollard and Lucy Pedler.

Attendance at all four sessions will make you eligible for Green Register membership

Event One: Fundamentals of Passivhaus, with Marine Sanchez

This half day session introduces the principles behind the Passivhaus standard (Thermal Comfort!) and the differences from normal construction so that everyone on the design team can understand the process. At the pre planning stage, the focus is mostly on how the choice of Massing/Shape and Glazing/Fenestration can make significant differences to how easily the design can meet the Passivhaus target. Post Planning permission, particularly at detail design stage, the emphasis shifts to ensuring that the actual construction is as close to the theoretical thermal performance as possible. In the UK this gap between theory and practice has become known as the “performance gap”. The main culprits are examined: lack of Airtightness, and problems with Insulation, such as a lack of understanding of thermal bridging and convective bypass, and how these impact negatively on the thermal envelope.  

Some attention as to the requirements for all seasons comfort are also discussed: Summer overheating can be dealt with by design if there is an understanding of the processes: seasonal shading, natural and/or mechanical ventilation, together with care over uncontrolled internal heat loads can deal with most problems without recourse to cooling in this climate. Minimizing Summer overheating is a core part of the Passivhaus target. 

Finally we take a look at the support and resources available in the UK, from to Passivhaus designers and building certifiers working in the UK.

Who should attend?
This course is aimed principally at building professionals in the UK:  Architects, Builders, Structural and Services Engineers, Quantity surveyors and Potential Clients – all can learn how to deliver real low energy buildings. It introduces the principles behind the Passivhaus standard and for achieving low energy performance. Unlike the full Passivhaus Designer course and exam, these sessions do not require calculations, but show the principles behind the standard so that every member of the design team can understand what the Passivhaus Designer on the team is doing.

About the trainer

Marine is a Building Physics Engineer and a Passivhaus Designer at Green Tomato Energy, the company which led the two first certified Passivhaus retrofits in the UK, Lena Gardens and Princedale Road. She herself led the delivery of the first certified EnerPHit refurbishment project in London. She graduated with an MEng from the illustrious French Engineering School, Ecole Centrale de Nantes. She then went on to obtain an MSc from Oxford Brookes in Sustainable Building: Performance & Design. Since joining greentomatoenergy, Marine has worked on numerous low-energy new build and retrofit projects using her skills in thermal performance modelling tools such as PHPP, WUFI and THERM combined with practical site experience. She has also performed post-occupancy evaluations and energy audits to assess actual performance of buildings and in turn to provide feedback to improve the design stage of future projects.
