The Passive House Institute offers a comprehensive range of services and resources to support the design, construction, and certification of highly energy-efficient buildings. These offerings include certification for buildings, components, and professionals; tailored training programs; and a wide selection of design and analysis tools. Central to the planning process is the Passive House Planning Package (PHPP), a validated energy balance tool. Additional resources include the Passipedia knowledge platform, a global database of certified buildings, literature, and ongoing events. The institute also offers services such as consultancy (what link?), research (what link?), and monitoring. Together, these tools and services provide a solid foundation for achieving and maintaining Passive House standards.
Certification ensures that the Passive House Standard has been met. Available for:
Buildings (Passive House & EnerPHit)

Passive House certification and consultancy provides trusted, third-party quality assurance that ensures buildings deliver the energy performance, comfort, and durability they were designed for—protecting both investment and climate.
We could also add an overview of the seals (picture)
Certification is carried out by accredited Building Certifiers worldwide or, in select cases, by the Passive House Institute itself. It provides independent quality assurance that a building performs as designed.
Certified Passive House: For new buildings that fully meet the Passive House criteria.
Certification supports better building performance, increased property value, and eligibility for various incentives—making it a key step toward reliable and sustainable construction.
Not sure if this is the right place but we could also mention and link the list of building certifiers

EnerPHit is the Passive House Institute’s certified retrofit standard for existing buildings that cannot feasibly reach full Passive House criteria. It ensures high-performance outcomes through one of two paths:
Energy-Demand Path: Achieves climate‑specific targets for heating/cooling demand (e.g., ~15 kWh/m²·yr)
Component Path: Requires consistent use of certified Passive House components—superinsulation, airtightness, high-performance windows, heat recovery ventilation, and minimized thermal bridges.
Retrofitted buildings can achieve energy savings of 75–90% while improving thermal comfort, indoor air quality, and long-term resilience. Projects may be staged using an EnerPHit Retrofit Plan within PHPP, enabling pre-certification and phased implementation.
EnerPHit certification validates documented performance—PHPP modelling, airtightness testing, ventilation setup, and component use—to give owners assurance that real-world results match design intent .

The Passive House Building Database is a global, free-to-access resource showcasing completed and in-progress Passive House projects. Maintained by the Passive House Institute and partners, it provides a detailed overview of certified and non-certified buildings worldwide.
Users can explore real-world examples by location, building type, or certification status, and submit their own projects for inclusion. Each entry includes key project data, PHPP results, and images—helping planners, designers, and building owners learn from proven Passive House solutions.
