the street frontages , such form manipulations were not achievable . The detail design of these façade surfaces therefore became the primary canvas with which to define the character of the building .
The adjacent busy traffic circle results in the building , for the most part , being viewed from a moving vehicle . For this reason , the design responds to this movement with a flush glazed “ skin of glass ” which wraps around the building , mimicking the curve of uMhlanga Rocks Drive . The use of coloured and tinted glazing is purposefully employed to create a distinctive checker board patterned façade , which takes its inspiration for the neighbouring building within the complex .
This affectionately named “ Bar Code Façade ” is appropriately bold in scale and extends over four of the office floors , articulated by recessed floors on ground and fifth , and is terminated by balconies at the east and west ends . This monochromatic super graphic approach challenges perceptions by blurring the distinction between window and façade cladding . Various design models were explored between the architect , sustainability , and façade consultants .
Minimising solar gain and internal glare issues of this North East to North West façade demanded that actual window area ( vision panels ) be limited to 35 % of the total façade area . This total area would also deliver the required natural light requirement without over-reliance on artificial office lighting , provided that the vision panels were equally distributed throughout the length of the façade and extended to internal ceiling height .
The balance of this façade comprises alternate white and charcoal coloured , back painted , glazing panels which form the external cladding to an insulated and gypsum lined interior . The use of low iron glass was utilised to obtain a true white colouration .
Sustainability Both developers of the Joint Venture embrace sustainability and green principles in the design and operation of its new building . From an early stage , it was decided that the completed project would be certified by the Green Council of South Africa . The design team , specifically Paul Carew Consulting , worked in close collaboration with Rewardsco , to realise a building custom-designed around the client ’ s needs and requirements , but still allowing for future flexibility .
The new building was designed to Green Building Council of South Africa ( GBCSA ) 4-Star Green Star rating specifications . These design criteria have included fly ash concrete mix in its construction and the use of low volatile organic compound , paint , adhesives and carpets .
Environmental control is by means of a watercooled air-conditioning plant which is serviced from a central chiller plant . Roof and wall insulation , as well as air-conditioning zoning also keep temperatures comfortable .
LED and low energy light fittings within common and office areas , infra-red motion controlled lighting within parking levels , and air source heat pumps for all water heating requirements , further assist in reducing the building ’ s energy demands . Daylight harvesting and installation of DALI lighting system ensure the office areas are kept bright while reducing overall electrical consumption .
Water saving sanitary and brassware fittings are employed throughout , which includes motion controlled urinals and taps . Stormwater harvesting provides landscaping irrigation needs .
A Building Management System ( BMS ) monitors the electrical demand , temperature control and water usage in all areas of the building . The system highlights areas where energy or water is wasted , enabling a quick response to resolve the issues .
Rewardsco received 4-Star Green Star Design Certification during construction and is currently in the finalisation process for submission to obtain 4-Star Green Star Built Certification . Thoughtful design was applied to Rewardsco creating a stimulating working environment that reduces building utility costs by employing sustainable alternatives to the benefit of the occupants .
