arches . Mirrored lifesaver buoys and netting create interest . Tensile sails further hint at a seaside environment .
Traditional warehouse-style ceilings were used . Structural steel is painted and exposed . White painted tongue-and-groove ceiling boards were used to complement . The spacious volumes created the opportunity to suspend maritime objects . Colourful flags and banners add to a festive atmosphere .
The original design intention was to suspend whale and dolphin skeletons from the ceilings of the main courts . The South African Museum has been consulted in this regard . In the absence of ‘ real ’ artefacts , large photographs are suspended as temporary structures .
The maritime theme is translated in the detail of the mall furniture where a combination of painted steel , timber and perforated metal was used to complete the elements .
The result is a mall with a spacious maritime feel , with a balance between architectural integrity and retail theatre .
Air-Conditioning Installation : Elshove & Pryce The primary design considerations for the airconditioning systems were those of flexibility in order to accommodate a variety of tenant layouts ( with the associated variations in heat loads throughout the complex ), energy efficiency and reduced long-term running costs .
A central chilled water system was chosen , consisting of four screw type water chillers located in a plantroom at the rear of the building , which was easily accessible via the service road . Each of the chillers is provided with a dedicated low profile cooling tower . The chilled water produced is pumped to each of the air handling
units via a ‘ ring main ’ of insulated pipework located in the ceiling voids above the shops .
Due to the close proximity of the cooling towers to residences , they were housed in a brickwork enclosure above the chiller plantrooms , with the air drawn in via acoustic type louvres in the façade of the enclosure . The cooling tower fans are variable speed , thereby further reducing the radiated noise , especially during the off-peak after-hours periods .
In order to ensure an efficient and cost effective operation of the central chiller plant , a variable volume secondary pumping system was used . A dedicated chiller plant BMS system measures
