What curtain wall system performance benefits most directly contribute to reduced operational costs over time?

Several curtain wall system performance characteristics yield direct reductions in operational costs. Thermal efficiency (lower U-values) reduces heat transfer, decreasing heating and cooling loads. Effective thermal breaks in metal frames and high-performance IGUs are primary contributors. Solar control measures—low SHGC glazing, external shading, and strategic fritting—reduce peak cooling loads, which can translate into smaller HVAC plant sizing and lower energy bills.

Airtightness and water management reduce infiltration-related energy losses and prevent moisture-related degradation that increases maintenance costs. Systems with superior air leakage performance support more stable indoor environments and reduce the burden on ventilation systems. Daylighting strategies that maximize useful daylight while controlling glare can significantly reduce lighting energy consumption when coupled with daylight-responsive controls.

Durable metal finishes and corrosion-resistant materials decrease frequency and cost of façade maintenance, while modular unitized construction simplifies targeted repairs. Collectively, these performance attributes yield predictable operational savings that accumulate over the building lifecycle, improving net operating income.
