Structural strategy
The RIBA Passivhaus Overlay, published by the RIBA in 2022, states in relation to the structural strategy: ‘With a focus upon the interfaces between primary and secondary structure develop the airtightness strategy, thermal integrity strategy and thermal bridging mitigation strategy by scheduling risks and then reducing complexity by considering the erection sequence, developing a detailed understanding of material properties and characteristics, and their suitability/impact upon PHPP models and project risks. Where appropriate, liaising with the Passivhaus Designer/Consultant, agree which thermal bridging calculations require calculation.’
