consideration was needed to give the balance
required between the amount of natural light
transmission in LUX levels and the
corresponding heat gain,” Scrowther says.
A favourable level between solar reflection
and solar absorption had to be attained in
order for the protection offered by the glazing
material to be effective. The objective, “Is for
the glazing material to move or redirect the
heat energy away from the surface of the
panel, back toward the outside of the building.
This allows for the heat to dissipate back out
into the atmosphere and prevents the
transference of unwanted heat into the
building, via conduction through the glazing
system itself,” explains Scrowther.
The system aims to maximise natural
daylight, therefore, Danpal had to implement a
solution which would deal effectively with the
infrared problem. “This type of light energy is
the carrier of what we experience as heat and
The area where the skylight is found is a frequent walk-through.
is closely related to the visible light
spectrum. If a sufficiently developed
solution to reduce IR and near IR without
negatively affecting the visible light
spectrum, is not introduced, heat gain
will persist,” Scrowther shares.
The result
Scrowther notes that there was close
cooperation between key role players
such as green building engineers,
architects and daylight specialists. The
Danpalon multicell panel developed used
a co-extruded low emissivity (low-E)
treatment as well as a performance
oriented reflective grey finish.
“This combination reduced the LT to
an acceptable level, but most
importantly, halved the infrared
penetration through the translucent
roofing. The result is a skylight roofing
solution which matches the SHGC figure
laid down by Solid Green, necessary for
the existing HVAC system to operate
effectively,” he says.
Matlosana Mall
The mall measures 65 000m 2 in the town
of Klerksdorp in North West Province. The
site is roughly 20 hectares in area, flanked
on the north side by the N12 highway and
on the south by a seasonal wetland.
The design had to accommodate all
major nationals, 265 shops, six movie
theatres, a gym and an office component
on the first floor. The brief also included a
food court surrounded by restaurants and
fast food outlets. The restaurants
included covered and outside sitting
areas. The site had to be developed with
three future development pad sites, two
full intersections from the highway and
five parking bays per 100m 2 of retail.
The mall design won the SAPOA
Shopping Centres Category A Award
in 2015.
