WATERWISE FEATURES
The building achieves significant water savings through
low-flow fittings, dual-flush toilets, rainwater harvesting
and a water treatment system. Black water provides
water for flushing and irrigation purposes. In terms of
landscaping, drought-resistant plants were chosen, which
eliminate the need for irrigation. “It was important for us
to support local biodiversity through our xeriscaping,” says
Kamohelo Selepe of Solid Green.
As well as incorporating sub-metering, Balwin took
the decision to place signboards throughout Greenbay
that display the estate’s energy and water usage, as well
as information on recycling and the location of amenities.
Tinney views these as learning resources that raise
awareness among residents about sustainable living.
To bridge the divide between the natural
and built environment, a biophilic
framework was developed.
Additional green features include having an excellent
visual connection to the external environment. “A direct
connection is provided for in 80% of the building’s
occupied area,” states Dean. To bridge the divide between
the natural and built environment, a biophilic framework
was developed. This framework integrates elements of
nature into the design, such as natural materials, plants
and natural lighting. “It was important that we used locally
sourced materials in addition to products with a high
percentage of recycled content,” she says.
Maintaining a high level of thermal comfort was also
a key consideration. “We achieved this by addressing the
internal operative temperatures through modelling and
ensuring they are within the ASHRAE [The American
Society of Heating, Refrigerating and Air-Conditioning
Engineers] Standard 55-2004 acceptability limits for at
least 98% of occupied hours,” says Dean.
Reducing waste was another objective. “An
environmental management plan was developed and
implemented throughout the building phase to establish
guidelines to minimise the environmental impact
associated with construction,” explains Dean. Moreover,
a waste management plan was put in place to minimise
the amount of waste going to landfill during construction.
Solid Green also helped devise a waste and recycling
management plan for the operational phase of the building.
SETTING THE BAR HIGH
Dean is most proud of the fact that the project achieved the
6-Star Green Star design rating, which sets the bar quite
high for future projects: “It is encouraging to see the positive
impact that a certified Green-Star building can have on the
environment, building users and the surrounding community.”
Selepe agrees, saying the certification is a huge
accomplishment. “What really stands out for me is how
united the project team was throughout the entire process,”
she shares. “It was clear that we all had the same goal and
were committed to making this initiative a success.”
Dean hopes that other projects will emulate some of the
building’s underlying principles. “These include energy
efficiency, water conservation, waste reduction and recycling,
minimising the use of raw materials, providing a comfortable,
healthy indoor environment, encouraging pedestrianisation
and sustainable transportation, and incorporating
landscaping that supports local biodiversity,” she says.
From a user perspective, the response has been
overwhelmingly positive, says Brookes. “It’s been a rewarding
experience to see the impact our efforts have had on the
community and it has been great to set the standard for
the area.”
