to targeting a more ambitious 5-star As-Built rating . In addition to this Arup have also been appointed to assist the anchor tenant , Nedbank Ltd , in targeting a 5-star Interiors Fit-Out rating .
Features that helped achieve the 4-star Green Star design rating : Preliminary calculations show that the project will achieve a 36 % reduction in energy consumption over the Green Star benchmark . Both passive and active strategies are being implemented to achieve this target . The façade is optimised for both thermal performance and daylight harvesting .
The development has two primary sources of cooling :
• Air-cooled chillers with assisted ice storage system for the Nedbank portions of the development .
• VRF air conditioning systems to the A-grade office spaces of the development .
• The main refrigeration plant shall have a reverse cycle heat pump to cater for the low heating requirements of the development . The lighting has been designed for optimal energy efficiency via :
• Good daylight levels , with the use of occupancy sensors for switching , saving energy when unused .
• All lighting will have LED sources , which are energy efficient
• Lighting zones in the offices do not exceed 100m 2 , which allows for only the occupied spaced to be lit .
Carbon dioxide monitors in offices and carbon monoxide monitors in basement car park to ensure that optimum amounts of outside air is delivered to the building .
Water and energy metering systems monitor and manage consumption . The first step in building water efficiency is to limit the demand . This will be done by means of installing low flow fittings . The project team created an initiative ‘ Create with Waste ’ which encourages upcycling of construction waste in the project in innovative ways .
Conclusion Park Square ’ s open design reveals the human activity taking place within the development . The result is a visibly connected , integrated and open community where people can come together in a vibrant , urban space .
Ken Reynolds , a director at Nedport Developments says , “ Projects like Park Square are effectively turning the South African urban planning paradigm around . This innovative and connected space encourages people to think beyond the boardroom , take time to unplug and to connect with one another . By similarly drawing the surrounding communities for shopping and relaxing , the overall effect is a sociable , communal space that emphasises a convenient and balanced work life experience .”
