INTERNATIONAL DEVELOPMENTS: WINNER Ecobank, Accra, Ghana The overall vision was to create a world-class facility that is contextually rooted and celebrates the spirit of Ghana. The development is defined by best practice green principles in creating an energy efficient building. The design is characterised by two building components mediated by a multi-volume entrance atrium which supports movement and connectivity. The tallest element houses the executive office component at fourteen levels high, while the lower component accommodates the public banking hall complimented by meeting rooms, canteen and auditorium. The design forms an easy flow of interior spaces without losing connection with its exterior. This is achieved by means of a focal spiral staircase, leading up to a glass ceilinged pane and the use of floating light fittings and glass layering throughout the design. Energy modeling and simulating energy consumption over an entire year was necessary to optimise for the tropical climatic condition. Careful selection of glazing systems and exterior shading were strategically integrated as energy efficiency measures for glare and heat gain reduction. Close communication and collaboration with both local and international suppliers was fundamental in the design and building process to deliver a solution that would be within budget, innovative and would not compromise on quality. Numerous challenges were overcome by embracing sustainable and economical building solutions. An optimised response to solar orientation, balanced with an inside out approach that incorporated its immediate context was integral to the design. A key focus was to create a clear separation between public and private functions with cross programming of spaces in order to maximise flexibility. A sense of infinity and growth is created through abstraction; spiral and extraction design elements and technologies were developed to create the dynamic building form. Building construction in Ghana is challenging as a result on non-availability of local industries and suppliers of materials. As most items had to be imported, procurement and time management was of paramount importance. Close communication and collaboration with local and international suppliers was fundamental in the design and building process to deliver a solution that would be within budget, innovative and does not compromise on quality. Innovation from the design start right through to furniture selection was achieved through the hands on approach adopted by all consultants involved. The end product succeeding in end user satisfaction within its unique cultural surrounds.
