Sydney Commercial Headquarters
High-Performance Curtain Wall & Commercial Glazing System for a Premium Grade-A Office Tower
Project Overview
A landmark Grade-A commercial headquarters in Sydney's central business district requiring a complete high-performance curtain wall system and commercial glazing package. The project demanded thermally broken aluminum framing systems with exceptional acoustic performance to meet stringent Australian commercial building standards, while achieving a 6-star Green Star energy rating through advanced low-E double-glazed units with argon fill.

Challenges & Solutions
Thermal Performance for 6-Star Green Star
Implemented thermally broken aluminum profiles with polyamide inserts and 44mm double-glazed low-E units with argon fill, achieving U-value of 1.8 W/m²K and SHGC of 0.27 to minimize solar heat gain while maximizing daylight.
High-Rise Wind & Water Resistance
Designed curtain wall system with pressure-equalized rain screens and structural silicone glazing, tested to AS2047 at 5.0kPa positive and 4.0kPa negative wind pressure, ensuring zero water penetration in Sydney's exposed coastal wind conditions.
