This one-hour technical webinar examines how predictive, physics-based energy modeling serves as the backbone for transforming existing building stock into certified EnerPHit projects. While Passive House modeling is traditionally seen as a design tool for new construction, its most potent application may lie in the strategic retrofit of existing envelopes. Participants will learn the methodology of Model Calibration: the process of aligning a PHPP (Passive House Planning Package) model with historical utility invoices. By normalizing for weather and operational behavior, practitioners can close the "performance gap" before the first hammer hits a nail. The Bottom Line: Through real-world case studies, this session demonstrates how integrating measured data with the rigorous PHPP engine supports informed decision-making, reduces technical risk, and provides a reliable roadmap to achieving the EnerPHit standard.
