How do energy-efficient glass curtain walls support sustainable design in large convention centers?1

Energy-efficient glass curtain walls are a cornerstone of sustainable design for large convention centers because they reduce HVAC energy use, optimize daylighting and contribute to measurable green-building certifications. For convention centers in the Middle East—such as Dubai or Doha—and in Central Asian cities like Almaty, integrating low-e coated IGUs, spectrally selective frits, and appropriate shading elements limits solar heat gain while admitting balanced daylight for exhibition halls and breakout rooms. Thermal breaks, insulated framing and warm-edge spacers minimize thermal bridging, reducing peak load on mechanical systems in hot climates and improving comfort during seasonal temperature swings. Advanced daylighting strategies—using vision-to-solid ratios and daylight redirecting frits—reduce reliance on artificial lighting during daytime events, which can materially lower operational energy consumption for long-running conventions. In addition, operable ventilation louvers or ventilated double-skin façades can be integrated to harness stack effect and reduce cooling demand during cooler months, a strategy applicable in continental climates of Central Asia. Lifecycle considerations—such as durable coatings, maintainable sealants and replaceable IGUs—ensure long-term performance and reduce embodied carbon by extending façade service life. For convention center owners targeting LEED, BREEAM, or regional sustainability benchmarks, energy-efficient curtain walls are a highly visible, quantifiable means to reduce operating costs and demonstrate environmental leadership.
