Site inspections and feedback
Detailed site reports that support a useful, practical and fully functional feedback loop are invaluable. Discussing the contents of the reports with site managers, rather than simply handing over the document, is critical to establishing this feedback loop. The key thing here is the fact that, compared to standard practice, a closer working relationship is required for Passivhaus projects.
Site inspections may be made by the design team on a periodic basis. For this reason the site reports that they produce are only a snapshot in time. The best site reports also record the lessons learned from the site visit so that they may be fed forward to subsequent phases of the project and for future projects.
