Located in Accra, Ghana with a gross leasing area of about 18 000m2. The design strives for cutting edge green principles and energy efficient performance. Computerised energy modelling was used to simulate the building's possible energy consumption and to assist with the decision making and strategy towards material choice and design. A double glazed high-performance glass product was selected for maximized views, to allow natural day light in and to aid in HVAC load reductions. The use of exterior shading necessitates energy efficiency, minimizes glare and reduces heat gain.
