Site evidence strategy
The RIBA Passivhaus Overlay, published by the RIBA in 2022, states in relation to the Site Evidence Strategy: ‘This is a plan for capturing site evidence including inspections, photos, airtightness testing regime, commissioning and handover programme. When appropriate, witness statements are prepared after a Passivhaus Designer/Consultant attends site, witnesses a specific/critical activity being undertaken, or addresses any questions or uncertainties that may arise (interpretation of standards/protocols etc). Their purpose is to confirm the works were undertaken in accordance with the construction documents/contract.’
