The Passivhaus Bitesize course introduces the key principlesof what makes a good low energy, comfortable building, based on the Passivhausstandard. It is delivered in a series of half-day online sessions.

 Brief Overview

Who are the Bitesize sessions for?
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.

Building Services for Passivhaus
What building services are necessary for a Passivhaus? This half-day session explores the different services required in true low energy buildings. In these buildings, the heat requirement is usually smaller than the other loads such as hot water. One of the reasons for this, other than the fabric first approach, is the adoption of mechanical ventilation with heat recovery (MVHR) systems. These mechanical ventilation systems need to be integrated into the building for successful operation, and we look at the necessary components, how they should best be installed, their space requirements, and where the supply and extract ducts need to be terminated. The maintenance access requirements (for filter changes) are considered. We touch on commissioning and how this needs to be carried out. There is a small group exercise of finding suitable locations and spaces for the equipment on a simple plan, all from the point of view of a non-specialist.

The second part of the session looks at how the choice of fuel for heating and hot water system can be different from conventional buildings: the Passivhaus requirement for heating systems is to produce a continuous trickle of heat, rather than a conventional system switched on and off by a time switch. The design of hot water systems can be improved to minimize losses, using radial plumbing in small diameter pipes, and there is a short group exercise on this. The definition of primary energy is explained and how to pass the Passivhaus requirements for this, in particular the effect of fuel choice and the difficulties communal heating systems can bring.

The trainers

UK experts – our trainers are the experts who aresuccessfully designing/ building Passivhaus in UK. Our collective experienceincludes non-domestic building, large residential schemes and real Passivhausconstruction experience.

Highly experienced trainers – amongst others, Bill Butcher,Eric Parks, Mark Siddall, Alan Clarke, Sally Godber,  Mike Roe, Will Southand Nick Grant. Not to mention Peter Warm and the rest of the WARM staff whohave supported over 200 buildings in low energy design, and are Passivhaus certifiers.
