What is a Passive House and Passive House Certification?
In the architectural world, a revolutionary concept was created, known as Passive House – energy-efficient havens that prioritized thermal comfort and significantly slashed operating energy compared to standard buildings.
But wait, this is where it gets interesting!
These houses were designed to optimize energy conservation and provide a sustainable living environment. To prove their mettle, they underwent a rigorous certification process by either the esteemed Passive House Institute (PHI) or the prestigious Passive House Institute US (PHIUS).
PHI vs PHIUS: Why Two Different Certification Bodies?
You must be wondering, why two different certification bodies, right? Well, while both organizations aim to promote energy-efficient construction, they have different approaches and standards due to the varying climate conditions and building practices in different regions.
PHI focuses on the international market with its European Standard, while PHIUS tailors its standards to the specific needs of the North American climate with its American Standard.
Key Similarities and Differences
But what about the key similarities and differences? Both PHI and PHIUS certifications use similar metrics to assess the energy performance of buildings, but the methods of measurement and specific standards differ between the two certification bodies.
For example, airtightness is measured using different units: PHI uses “air changes per hour at 50Pa” (ACH50), while PHIUS uses “cfm/ft2 of envelope area at 50Pa.” Additionally, the criteria for heating and cooling requirements vary, with PHIUS considering factors such as building size, occupant density, and location.
Energy calculations also differ, with PHIUS using net source energy demand and PHI using Renewable Primary Energy (PER) demand.
Understanding these similarities and differences is crucial for architects and builders to ensure compliance with the specific certification standards.
Benefits of PHI and PHIUS-Certified Windows
