Passive House Windows:

A new ‘pane’ threshold for high performance buildings?

This presentation will look at the influence of Passive House on the evolution of window design for the high performance building marketplace and how Passive House has created a new ‘pane’ threshold for building designers and specifiers.  PHI and NFRC certification protocols will be reviewed to determine optimum window performance criteria for our climate.   A few simple window construction details will be compared to illustrate how minor changes to our designs can have a major impact on performance.

About the Presenter: Bronwyn Barry works as a Director for One Sky Homes, a Silicon Valley Passive House and Net Zero Energy Design|Build company. She is a Certified Passive House Designer.  Her presentations on high performance windows have been locally, nationally and internationally recognized.  She serves on the Advisory Board and is a founding member of Passive House California (PHCA) and the American Passive House Network (APHN.)

Learning Objectives:

  • Understanding window performance testing protocols, how they are calculated and what they tell you about the product
  • Why Passive House and NFRC window performance ratings differ
  • How to improve the performance of your building by design, using regular windows
  • Which details matter: flashing, installation or air sealing?

Net Zero/Passive House

Friday, July 27
Noon- 1:30
A presentation of the Forum on the Environment

Prudence Ferreira will present the impacts of climate change on water availability, power service, ecosystem destruction, pose a serious and urgent challenge to the design and construction community to reach beyond a prescriptive green building approach and utilize methodologies that reliably and predictably produce dramatic energy demand reductions. As the state of California struggles with the best path to achieve the GHG emission reduction goals established by AB32, a community of practicioners has emerged that are utlizing the Passive House path to achieve zero energy targets. Learn about this performance based standard and how it is being used a springboard for high-performance residences and buildings that are using roughly 1/10th the energy of conventional buildings while providing superior comfort and indoor air quality.

Speaker Bio: Prudence Ferreira is a San Francisco-based energy and building science consultant committed to supporting low-energy, zero energy and carbon-neutral design and construction via the Passive House path., and Principal of Integral Impact Inc. Utilizing a physics-based approach to enhance energy performance, indoor air quality and comfort, she and the Integral Impact team provide energy modeling and analysis, building science consulting, education, design support and verification services to developers, building professionals and property owners, from pre-design through final certification, for residential, commercial and corporate projects.

Rooftop Photovoltaics – How to Save Money on Energy and Avoid Spending It On Roof Repairs

Friday, June 22, 2012
Free. Please RSVP to for room set-up

The use of rooftop solar photovoltaic (PV) panels has increased dramatically as have problems with the roof coverings over which they are installed.  This presentation discusses some practical ways building owners and design professionals can reap the benefits of conserving energy and avoid unwelcome surprises associated with non-fire rated systems, roof leaks, premature roof deterioration, inadvertent voiding of roof covering warranties, compromised access for fire suppression efforts, and excessive costs associated with temporarily removing and reinstalling PV panels to effect needed roof maintenance and repairs.

About the presenter: Philip D. Dregger, PE, RRC, Technical Roof Services, Inc. (TRS). Phil Dregger is a professional
engineer, registered roof consultant, author, and fellow of the Roof Consultants Institute. He has investigated
problems and provided testimony regarding virtually all types of roof and waterproofing systems since the early 1980’s.
He has special expertise in roof wind damage (hurricanes), rooftop solar photovoltaics (PV), and complex moisture
accumulation problems. Dregger has authored several articles on roof technology.

Learning Objectives – Understand practical considerations related to long term successful performance of rooftop solar photovoltaic systems (including integrated, roof bearing, and rack mounted systems) and the roof coverings they are installed upon.

  1. Protecting Existing Roofs – leaks, warranties, and durability considerations.
  2. System Design – Class C fire ratings, wind uplift on “open” arrays, and “cooling penalty” of integrated panels.
  3. Panel Installation – “Creep” of non-penetrating systems, excess heat transmission to roof below, billowing of mechanically attached single ply roof membranes).
  4. Future Roof Access – panel cleaning, roof maintenance, and pathways for fire suppression.
