A Passive House Network Symposium

Fenestration Focus

Scaling High-Performance Domestic Supply & Demand

Wednesday, March 9, 1 - 5 PM ET

In Cooperation with:
The Passive House Institute & The Facade Tectonics Institute

Thank you presenters, attendees and sponsors for a great event! Stay tuned for more information about it.

In Cooperation with:

The Passive House Standard has driven a global shift in the performance expectations of what a fenestration system can and should provide, and as demand grows is transforming fenestration manufacturing from Ireland to China. Domestic demand and production are growing too, but how do we accelerate this trend? How can we support and transform our local fenestration industry to produce and deliver the fenestration products with performance metrics that we want and need? 

This symposium seeks to demystify Passive House fenestration performance standards, their relation to traditional American approaches, and what it takes to grow demand and supply.

Presenters include notable local fenestration researchers, manufacturers, and advocates, whom we’ve paired with our colleagues from the Passive House Institute. Together we hope to shed light on how to advance market appreciation of the key role that high-quality fenestration plays in delivering building decarbonization, and better appreciate the certifications, codes, and manufacturing practices that can make it all possible. 

Join this conversation and help us drive demand, and build local manufacturing capacity.

Session 1

1 – 3 PM ET 

Metrics & Certifications

Glass | Spacer | Frame | Installation

The Passive House Standard pays detailed attention to doors and windows. It breaks down these critical components into these specific elements: glass; spacer; frame and installation. It further requires that each element meet specific performance metrics and that all work together to deliver customized metrics specific to each window.  This granularity is what sets Passive House Certified windows apart.  

North American Fenestration Rating Council (NFRC) calculates window performance using a different algorithm and delivers performance outputs as a whole window rating. This sets up confusion between the two rating systems, which are not interchangeable and hinders the U.S.-made fenestration products from being specified for local Passive House projects.  

This session will provide a broad overview of the two systems, to form a baseline understanding for what each certification framework does, looking at how we can use both pathways to support better building outcomes.  

Session 1 Agenda

Introduction by Bronwyn Barry, Founder passivehouseBB

Fenestration Certification Overview: Metrics and Certification Standards, Targets & Process. by Adrian Muskatewitz, PHI

Translating PHI metrics into AmericanHow does this stack up with NFRC and US window certification and what’s the converter? by Daniel Haaland, RDH

Looking at both frameworks to weigh impacts and benefits. by Helen Sanders, Technoform, FTI

Panel Discussion, moderated by Bronwyn Barry

Session 2

3 – 5 PM ET 

Policy Mechanisms to Accelerate High-Performance Demand & Scale Manufacturing

Codes | Incentives | Training | Rebates

We know high performance windows are available on the US market, but aren’t often specified. What are the policy mechanisms we can use to increase specification of existing products to accelerate the production of more high performance windows? Can increasing Passive House Certified windows play a role in this local market transformation? In this session we’ll explore possible code barriers to scaling high performance fenestration growth. We’ll also share solutions being used elsewhere to drive market transformation of this important building envelope component.

Bronwyn Co-founded both  Passive House California (PHCA) and The Passive House Network. She was an active contributor to the UNECE’s Coalition on Buildings, working to develop a global standard for high-performance buildings. Bronwyn has contributed as a subject matter expert on a number of research projects in collaboration with researchers at Lawrence Berkeley National Labs (LBNL). Most recently she worked with California’s Codes and Standards team on exploring a Multifamily Passive House Reach Code for California. Bronwyn holds a Bachelor of Arts from the University of Natal-KwaZulu.

Daniel Haaland, Associate, Building Science Engineer, RDH

Daniel leads our Thermal Simulation team, our in-house group dedicated to analyzing the thermal performance of building enclosure systems and assisting clients in achieving their low energy/high-performance targets. As the lead author of several industry guidelines and standards related to thermal modeling, including the CSA Z5010 Standard and the THERM PH Window Simulation procedure, Daniel is an industry leader in this field. Prior to joining RDH, Daniel completed a master’s degree in Building Science at the University of Toronto, where his research focused on indoor air quality and occupant comfort.

Helen Sanders, Technoform & Facade Tectonics

Helen Sanders has 25 years of experience in glass technology and manufacturing, with expertise in functional coatings, insulating glass and thermal zone technologies for fenestration. She is an active member of several industry organizations, including president of the Facade Tectonics Institute, vice president of the Insulating Glass Manufacturers Alliance (IGMA), and immediate past president of the Glazing Industry code committee. She has a Master of Arts in Natural Sciences and doctoral degree in Surface Science from the University of Cambridge, England.

Peter Dushenski, Managing Director, GlasCurtain
