EnerPHit management plan
The RIBA Passivhaus Overlay, published by the RIBA in 2022, states in relation to the EnerPHit Management Plan: “This plan includes an assessment of retrofit strategy and certification strategy (single phase or step-wise), surveys to gather data about the existing building, and strategies to address the specific demands of the building and site. This whole building retrofit plan includes modelling the existing building in the Passivhaus Planning Package (PHPP) to provide detailed calculations of the existing fabric performance of the building. Importantly, all approaches to retrofit, including EnerPHit, require some augmentation to deliver robust solutions addressing all aspects of the retrofit performance gap and unintended consequences. Consider: energy use (e.g. CIBSE TM22), a BUS survey, dimensional, moisture, thermographic and air leakage, building condition. Where appropriate analyse data using metrics that map onto Passivhaus benchmarks. Integrate with moisture risk assessments.”
EnerPHit is the Passivhaus certificate for retrofits.
