extraction, sump pumps as well as the fire and
security systems.
Minimisation of greenhouse gas emissions
associated with operational energy consumption
is reduced. An energy model of the building
was generated and in the design stages of the
building compared to a notional building model.
The building design showed an improvement over
a SANS 10400 notional building. The building is
designed to achieve an energy consumption
of approximately 209,5 kWh/m 2 /annum which
amounts to over a 60% improvement of energy
use when compared to the notional building. There
are potential carbon saving of 251,4 kgCo2 per year
compared to a notional building.

Water Saving Initiatives
The water system is estimated at saving ±30%
translating to ±2,742kl of water saved per annum.
The building achieves savings through the use of
water efficient fittings that limit the occupant water
usage. Sub-metering of major water consuming
systems is in place. Gathering information is key
to understanding and managing building systems
and to assess opportunities for water savings. The
building is designed to reduce the consumption of
potable water for the building’s fire protection and
essential water storage systems.
