PHI’s EnerPHit standard takes account of what makes existing buildings hard to certify: foundations, party walls, historic fabric, and cost. This course covers its criteria, its two certification methods, and the exemptions available, then follows successful retrofits through airtightness, insulation, thermal bridges, windows, and ventilation.

The Marnix, the 1965 ING headquarters by SOM, given 50 more years by deep retrofit and adaptive reuse: primary energy down 85% and CO2 emissions 75%, at 20% less than a conventional renovation, per the source.
Lessons from verifying deep energy retrofits in New York City and Pennsylvania: envelope assembly checks, airtightness testing, and HVAC verification, and how they keep field work true to design intent so EnerPHit delivery can scale.
EnerPHit retrofits delivered one apartment at a time, from Casa Baretti in Bergamo, the first EnerPHit certification for a single apartment, to projects near Naples, and how the approach adapts across climates and scales up.
Lessons from the REALIZE-CA demonstrations, supported by the California Energy Commission: panelized exterior overclad retrofits of 1960s low-rise multifamily townhomes, the construction challenges, and sensor data on how the retrofitted assemblies perform.
EnerPHit retrofits taken step by step: a phased approach for three schools in a London district, using PHPP as a decision-making framework within real funding limits, and the reuse of metal buildings as affordable rural workforce housing.
