Stop Throwing Building Performance Out the Window: sponsored by AIA Spokane

Course Description:
With up to 60% of a building’s energy loss occurring through windows and openings, this session delivers a science-backed checklist for designing and installing high-performance windows and window framing systems. Learn how to minimize thermal bridging, maintain thermal alignment, eliminate air and moisture infiltration, and achieve measurable efficiency gains — all while meeting ASHRAE 90.1 requirements, voluntary certification programs, and emerging stretch codes to future-proof your designs and maximizing sustainability, occupant health, safety, and welfare while enhancing long-term building value.

Windows and openings play a significant role in the overall efficiency of a building envelope. GreenGirt CMH XO is a structural composite metal hybrid sub-framing product used to provide a thermal break by bringing windows into alignment with the thermal plane of the continuous insulation.

Design Considerations:
GreenGirt CMH XO addresses the decade-old issue of significant thermal loss at openings by eliminating through-wall metal, through-insulation fasteners, conductive metal angles, and inefficient wood-blocking.

Learning Objectives:
1. Participants will be able to contrast conventional recessed windows with systems that align the thermal plane of the window with the thermal plane of the insulation system.
2. Participants will be able to interpret and apply ASHRAE 90.1, voluntary certification programs, and emerging regional stretch codes to the design of window assemblies.
3. Participants will be able to implement best practices for energy-efficient windows and openings that address thermal performance, air leakage, integration with building envelopes, and other key factors.
4. Participants will be able to integrate high-performance windows with continuous insulation and building enclosure systems to deliver code-compliant, sustainable façades that enhance occupant health, safety, and long-term building value.
