Passive House Retrofits: The EnerPHit Standard (Live Online)

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

Key points

• Why EnerPHit was developed, and how it keeps Passive House health, comfort, and efficiency within reach of existing buildings.
• The two EnerPHit certification methods: where their criteria differ and where they agree.
• How comfort criteria and ventilation requirements drive the design.
• Exemptions for existing and historic buildings that can’t meet the standard route.
• The EnerPHit Retrofit Plan, for renovation step by step.

Learning objectives

• Outline the 5 basic principles of Passive House design and how each principle contributes to the health, safety and welfare of occupants.
• Describe why and how hygienic ventilation is an essential defining component of Passive House design and operation. And outline how the Passive House design focuses on very good energy efficiency which results in side-benefits like great occupant thermal and acoustic comfort, improved occupant health outcomes, and economic affordability.
• Outline the major Passive House tools: PHPP, DesignPH and Therm, and provide an overview of the tools in correlation with data-driven design.
• To understand how to get from where the participant is now to building a building adhering to the international passive house standard through applicable case studies. And illustrate the data-driven’ design process used to help projects meet their comfort, durability and climate goals.
