An extension of the regular façade beyond the building volume with screen walls generates a continuous glass sheet toward the eastern plaza and merges the two buildings into one. The tower is constructed as a concrete frame with stiffening core and perimeter columns. Structure and façade are designed for flexibility in office lay-outs and allow open plan, cell and combine offices as well as multiple tenants per floor. The façade module of 2,70 m fosters a generous ambiance of space.
Sustainable initiatives include the abundant and recurring strategies of daylight, air and water. A windproof, exterior automatic operable sunshade on the southwest façade allows for reduction of solar loads along with automatic interior perforated louvers on the other three facades. Natural ventilation is provided via hopper windows operated via chain motors and held by scissor hinges. The flat concrete slab is equipped with PVC water tubes to cool and heat the exposed thermal mass of the structure.
