To construct the green office development, a number of sustainable initiatives were put in place, among them the installation of blinds to combat daylight glare and the implementation of ammonia (refrigerant) chillers, which have a high Coefficient of Performance (COP).
The site’s location also ensures good access to public transport, which provides alternative means of transport for staff and visitors. During construction, the absolute quantity of all Portland cement was reduced by 30% for in-situ concrete by substituting Portland cement with Ground Granulated Blast Furnace Slag (GGBS). The structural and reinforcing steel has as, on average across all types, post-consumer recycled content of more than 54%. Over 30% of the total PVC content by cost was reduced by replacing alternative materials. Fifty percent of the timber is specified to be either Forest Stewardship Council Certified, re-used or to have a post-consumer recycled content.
The end result is that the project, which optimises energy consumption, reduces running costs and uses resource-efficient methods of construction and installation of services, achieved the developers’ goal of attaining its 4 Star Green Star SA Office Design rating and 4 Star Green Star SA Office As Built rating. Accredited by the Green Building Council of South Africa, the 4 Star Green Star SA Rating represents “Best Practice”.
