Sampson Close PassivHaus Project

02 May 2012
Air Tightness

Orbit Heart of England :
Location : Sampson Close, Coventry
Value: £3m
Architects: Bailey Garner
Contractors: Wates Construction

We were called upon by the client to assist with the specification and supply of airtightness products to this innovative scheme.

Through a number of workshops with Dutch PassivHaus consultants, Trecodome, we assisted in the detailing of airtightness junctions and service penetrations to ensure that the scheme met the demanding target of 0.6m3/hr/m2 @ 50Pa required to certify the project as a PassivHaus scheme.

To put this in context, building regulations at the time allowed 10m3/hr/m2 @ 50Pa. We went on to assist the contractor with toolbox talks on site to ensure that the site management and trades on site understood how to achieve this demanding target.

EH Smith were instrumental in us achieving the demanding levels of airtightness on this project. Through detailing advice and on site support with toolbox talks, they supported us throughout.
