ARCHITECTURAL CONCEPT

The Continuous Curved Form

The architectural concept centers on a continuous curved curtain wall façade—a form that transcends standard rectilinear construction and demands precise coordination between design intent and engineering execution. The result is a building envelope that feels simultaneously bold and refined, framing coastal views while providing a high-performance thermal and structural barrier.

Compliance & Testing

Performance Standards

NFRC Energy Performance

The curtain wall system is designed in accordance with NFRC energy performance standards—ensuring thermal efficiency suited to Guam's coastal climate while supporting sustainable building envelope performance.

195 mph Wind Load

Engineered for Guam's demanding coastal wind conditions—the curtain wall system is designed to perform under wind loads up to 195 mph, exceeding the requirements of Guam's most exposed sites. Performance is based on project-specific design, configuration, and installation.

ASTM Air & Water Tightness

Curved façade systems present unique engineering challenges for maintaining consistent air infiltration and water penetration resistance across non-planar surfaces. All systems are designed in accordance with applicable ASTM standards to ensure reliable coastal performance.
