Design Options for Advanced Passive House Windows
- Southwall Technologies Inc.
Improvements in architectural glazing have long been identified as an efficient path to mitigate green house emissions, and the Passive House concept is a particularly effective concept for energy efficient housing construction in heating-dominated climate zones. Passive House Windows require a combination of superior thermal insulation (R or U-value) in combination with high solar heat gain performance (SHGC). For conventional window concepts that promise economical near-term market acceptance, this can be achieved with a careful combination of low-e glazing components (both class- and film-based) in multi-cavity Argon-filled Insulated Glazing Units (IGUs) for good ?center of glass? performance, selection of appropriate spacer concepts (to improve ?edge of glass? performance), and integration into high-performance window frames. This study presents the latest results of thermal modeling of Passive House windows, and compares the designs against Passive House performance metrics that apply to the European and North American markets. Window design options and their relevance to current market acceptance criteria will be discussed, and guidelines for balancing the design conflict between good R- or U-value and optimal SHGC will be presented.
