A certifier and consultant on the key requirements and process of Passive House building certification, where its complexity, cost, and time pressures come from, and how early planning and clear roles keep it manageable.
Wood fiber insulation, now produced in the US, in wind-tight, vapor-open assemblies: its performance, code-compliant assemblies, thermal bridging in cold climates, and how life cycle analysis shows its carbon benefits.
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.
High-performance windows through the lens of Passive House building science: how glazing, coatings, gas fills, frames, and seals shape heat loss, solar gain, airtightness, condensation risk, comfort, and durability.
Andrew Frederick of Croft, in Rockland, Maine, on combining Passive House-level energy performance, natural building, and Japanese and Scandinavian prefab methods, and what biomaterials mean for durability, moisture, constructability, and embodied carbon.
A rural, all-electric Passive House community in the Catskills, occupied and measured: clustered site planning, panelized construction, low-GWP assemblies, and carbon tracking, with what worked, what didn't, and which policies mattered.
