Passive house: construction and quality assurance!

Passive house: construction and quality assurance!

When building passive house buildings training of site operatives and undertaking detailed site inspections is all part of a good building process. Furthermore provision of robust feedback and the inclusion of a dedicated, on site quality assurance champion are all constituent parts of a successful delivery process.

With a sound design already in place, exemplary standards of on-site quality assurance are required in order for passive house buildings to perform appropriately. This means diligence and excellent standards of craftsmanship must be employed at all times. For a passive house project to be completed successfully, with minimised costly rework and remediation, experience suggests that there is a learning curve that needs to be addressed. This learning curve is not confined to the site office; it affects all trades on site.

Structured reviews that interrogate a passive house design are hugely beneficial, particularly for less experienced project teams. These reviews analyse each and every aspect of the design and the construction. Key characteristics:

  • They are not simply ‘compliance reviews’ – they dig into the details and examine the buildability, sequencing and construction programme.
  • Their purpose is to identify and expose risks that could impact upon project delivery.
  • They allow the project team the opportunity to formulate strategies that resolve the risks in an open and collaborative fashion
