WITH OVER 25 YEARS’ EXPERIENCE IN THE BMS FIELD...
PROJECT
Sole distributors and
authorised system
integrators of the Trend
product line in South Africa.
We supply, install, commission
and maintain quality BMS
for HVAC, Energy
management and
monitoring.
Pelser highlights another contributor towards energy
saving: “Sustainable water use is linked to electrical
consumption because a lot of the water you use in the
shower is hot, which requires electricity. So water
flow rates, for example, can also help reduce your
electricity consumption.”
37% WATER SAVINGS
Low-flow showerheads and tap fittings in both kitchen
sinks and wash basins aided this achievement. According
to Pelser, Hansgrohe taps, already fitted with restrictors
from the factory, helped the team go beyond the EDGE base
case flow rate. “Showerheads run at 5.7 litres per minute,
in comparison to the base case of 10 litres per minute.
Kitchen taps run at 7 litres per minute as opposed to
8 litres per minute, and bathrooms taps compare at
5 litres per minutes to the base case of 8 litres per minute.
Another prominent water saving feature is the dualflush
water closets, and installation of Geberit Abalonas
in lavatories. “The base case is 8 litres on the first flush,
and six litres on the second flush,” says Pelser. “Here, it’s 4
litres for the first flush, and 2.6 litres for the second flush.”
35% LESS EMBODIED ENERGY
IN MATERIALS
Although many materials used throughout the project
only meet the base case requirement, they have been
carefully considered with the future in mind. According
to Vos, the long-term lifecycle cost of the project
plays a key role in sustainable developments because
“the higher your maintenance cost, the higher your
lifecycle cost”.
Aluminium window frames are a base case requirement,
explains Pelser. They are, however, most suitable in the
long run considering the harsh Gauteng climate, resulting
in what Eva describes as a “maintenance nightmare”
– wood would have to be treated almost biannually. Along
with that, cored face brick has been used throughout the
different phases, also meeting the base case requirements.
