Buildings Envelop significantly impact energy use and load; High performance commercial window can help on multiple fronts
• Type of windows (Frames and Glazing) – host of design/cost criteria
• Window-to-wall Ratio (WWR)
• Daylighting <=> Advance electric lighting
• Thermal Comfort
• Ventilation

Advancements in the Performance of Glazing has been steep Cost effective highly insulating glazing solutions are available in market
Future opportunities around: • Deeper market penetration of triple glazing systems • Low-cost Dynamic Glazing • Durable Vacuum Insulated Glazing
Current Industry Norm
Available, but not common
Are the Framing Systems important?
4
Relatively small Frame area (5-25%) could accounts for significant (~30-70%) of window heat-loss even with good T/B Frames
Advance, cost-effective Framing and Glazing systems are required to improve the Commercial Building performance.
DOE EERE BTO has worked with Industry and research Partners
over the years to improve the
performance of both the Framing and Glazing
systems

Previous Generation AL Advance AL
• Over 90% of Commercial Framing system is made of Aluminum
– Though Thermal-conductivity of Aluminum is ~1000X of non-metallic options e.g. PVC
– Driven by Structural, safety, durability, aesthetics, ease of maintenance
– Energy performance was compromised
• Advancement in thermal break technologies, today’s aluminum frame windows can match energy performance of PVC, without compromising their structural performance

• An industry first – R5 insulation on an aluminum window
• An Architectural (AW) structural rating, the highest structural rating for windows
• 40% better thermal performance compared to other high-structural windows
• A wider thermal break and triple glazing, providing condensation resistance and comfort for those inside
• Minimal sightlines for superior aesthetics, and the flexibility to vary interior and exterior finishes
• Since it is aluminum, will never rot, warp or buckle due to moisture and weather exposure
• An ideal solution for Green Buildings• Passed blast and hurricane impact testing• Commercialized in less than two years
