AET underfloor air conditioning comes to building in Ghana
One Airport Square in Accra, the capital of Ghana, is believed to have the first underfloor air-conditioning system in the country. This 20 000 m2 mixed-use development has services designed by M&E consultant BDSP, which include AET’s Flexible Space underfloor air conditioning. There is 2000 m2 of retail space and 18 000 m2 of class A office space over 10 floors. It was designed by Mario Cucinella Architects.
The compact designed of this green-rated building (4-star Greenstar) includes an internal atrium to provide light and facilitate natural ventilation in the indoor space. Additional cooling is provided by the Flexible Space system.
The large structural slabs project beyond the facade outline to provide solar shading. This feature, along with different configurations of glazed facade and mixed-mode ventilation reduce the active-cooling requirement by over 30%.
The Flexible Space system serves the office areas. The floor plenum below the raised access floors is used to deliver conditioned supply air and also for return to the CAM-V33 units. Each floor is divided into four tenancy areas, each served by two CAM-V33 units.
Air enters the spaces via a fan terminal or Fantile unit, which has the benefit of individual personal control of airflow and temperature via the integrated Fatronic controller. There are over 900 standard TU4 Fantile units.
