    Passive House is the strictest energy efficiency standard in the world. It is a performance standard with rigorous and verifiable thresholds which have been met by many building typologies in every climate. The standard is also based on a comfort and health criteria to provide a holistic experience for occupants. While being very strict, once mastered Passive House is surprisingly flexible, providing designers multiple compliance paths and immediate performance feedback, backed up by a fast growing and evolving supply market and professional community. In this presentation Enrico and Andrew will cover the Passive House standard with an emphasis on commercial buildings, citing design considerations and examples.

    Considerations: Climate-specific approach, Comfort requirements, Form factor, Orientation,  U-values, R-values, Thermal bridge free construction

    Emphasis on Nonresidential buildings include: Physics of large scale buildings, Building time constant, Dynamic thermal properties of envelope assemblies, Use-specific requirements, Interior heat gains, Solar heat gains, Design heating load, Design cooling load, PHPP vs dynamic simulation, WUFI modeling

    EXAMPLES: Hotels, Sports Facilities, Schools, Offices, Museums, Production Plants
