The slightly inverted, cone-shaped 19-story building in transparent green that stands at the northeast corner of the Chaoyangmen Bridge interchange is the CNOOC Building - the China National Offshore Oil Corporation’s latest property development. The building floor plan is triangular with curved corners. When viewed from these corners the building looks like a vessel approaching from the sea. The green tinted, low-E glass in the curtain wall reflects the deep sea colors “Offshore”. The building’s curtain wall is a unitized system with mullions offset from one floor to the next. Clear laminated glass fins with clear-cut edges are hung externally to the mullions and can effectively scatter the sunlight, thus preventing glare on the wall. The spandrel panels of the curtain wall units are built with extruded aluminum cladding slats. The building’s full height atrium is designed with a fire-rated window wall from the 5th to 18th floors. The top of the building atrium is sealed by a 360 sqm(3,900 sq ft) skylight system. Scope of Work 16,000 sqm (172,200 sq ft) of curtain wall.
