selected are below maximum allowable limits as
per the guidelines.
Energy
The building achieves a 61% improvement in Carbon
Emissions over a SANS 204 National Building.
Energy sub metering is provided for substantive
energy uses within the building, as well as for
lighting and power on each floor.
Water
Water meters were installed for all major water
uses and are connected to a web-based monitoring
system to support proper facility management of
water consumption.
Rainwater harvested from the roof area is
collected and stored in 25 5kl tanks for toilet
and urinal flushing. Rainwater harvested from
surrounding hard surfaces is collected and stored
in a 46m3 sump pit for reuse on site.
Greywater, collected from sinks and showers,
is captured and treated for landscape irrigation
purposes – resulting in a 100% reduction in potable
water consumption.
Materials
Portland cement quantities reduced by 33.9%
as an average across all concrete mixes through
substitution with fly-ash.
A minimum of 90% of all project steel by mass
(including reinforced steel) has a recycled content
greater than 90%.
38
58.1% (by cost) of PVC content used on the
project is reduced through the replacement with
alternative materials.
51.1% (by cost) of all timber products used in
the building and construction works have been
sourced from Forest Stewardship Council (FSC)
certified timber.
Emissions
All refrigerants and gaseous fire suppressant
systems have an Ozone Depleting Potential of zero.
All thermal insulants have an Ozone Depleting
Potential of zero.
Outflows to sewerage system reduced by 86%
through the installation of water reuse systems.
No light beam generated from within or outside
the building is directed at any point in the sky
hemisphere without falling directly onto a nontransparent surface.
INTERIOR DESIGN
The Interior design proposal for the client PPS by
Boogertman + Partners Interior Design stemmed
from the concept of Biophyllia.
Biophilic design incorporates the idea of
biophilia - a human affiliation to nature - into
building design. Common biophilic designs
include features that allow for the entry of diffuse
sunlight, opportunities for contact with nature,
use of passive natural ventilation, the use of local
natural materials, and views of the outdoors from
the interior of the building.
