Rather than rebuilding as before after a wildfire, building forward: fire-safe strategies for buildings and their landscapes, integrated with Passive House design, and how they've been put to work after other wildfires.
Dylan Martello of Steven Winter Associates on PHI's Low Energy Building certification in multifamily buildings: its metrics, how they differ from Classic, and when LEB is the better optimization path, covering heating and cooling demand, airtightness, and ventilation.
The certifier, engineer, and developer on designing two terraced Passive Houses in Cartagena, Colombia, one of the hardest climates for Passive House: average monthly temperatures around 82°F year round, high humidity, and intense sun.
