  • 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.

Description:

Event two of our series of four half-day Passivhaus events held in conjunction with AECB CarbonLite.

How do I build a Passivhaus? How is it different from normal construction? This half day session answers these questions along with some specific guidance on achieving the level of airtightness and thermal bridge free construction required by the standard.

Airtightness, convective bypass, thermal bridging are discussed in relation to common constructions. Insulation materials are shown and their properties discussed, singling out those that are effective in damp and load bearing situations. Suitable airtightness materials are discussed and shown, and the necessity of an airtightness strategy discussed.

The session stresses the preferred option of designing out thermal bridges rather than using expensive load bearing insulation. Along with avoiding thermal bridging, keeping the airtightness layer simple on plan and site is stressed. You will get a chance to try your hand at detailing some common construction elements in a small group exercise.

Finally, but not least, a look at the contractual side and suggestions for ways responsibility can be allocated to carry the Passivhaus principles through to the on-site teams.
