ous heating and cooling within the different zones based on desired internal conditions . Each floor is fitted with a separate VRF system which allows for relative ease in accommodating future office ‘ churn ’.
Block C has a slightly different application for the first floor open plan area – this space is served by two Hybrid Roof Top units that are connected to VRF Heat Pump condensers . The rooftop is also fitted with an economiser allowing full fresh introduction when outdoor ambient conditions allow .
Block E has been fitted with a central controller that caters for temperature , time scheduling and many other value add features .
Fresh air is introduced into the buildings to comply with SANS 10400 Part 0 . Air is introduced into the space via either hard connections or discharge to the rear of the ducted units in exposed areas . Balancing dampers ensure the correct amount of air is delivered to comply with regulations .
BLOCK C – BOOGERTMAN + PARTNERS Architectural Features For Block C the façades facing north and south are near completely permeable with visibly linked large glazed expanses . The markedly more solid , east and west façades offer protection against solar heat gain and so does a finely meshed shading structure on the northern open terrace façade .
Double glazing to lower level , western façade glass offers occupancy comfort to meeting rooms and access to a Green Belt . Corobrik ’ s new black facebrick was used for the feature treatment of external façade elements . The same concept was repeated internally for brick enclosed service areas and feature walls .
Conceptually the B + P office is designed over 2 levels , but with greater floor to floor height to mimic the adjacent 3 storey buildings ’ overall heights . Overall height is also guided by a restrictive maximum height line , and an offset line from neighbouring residential area .
For Block C , the lower level caters for mainly client interface spaces , the baristareception area , with gallery / lounge spaces at the meeting rooms and large open plan collabcafe space where different flexible functions are accommodated ; model building , laser cutting , sample boarding , coffee drinking , printing and binding all happen here .
The upper level double volume office is the ‘ creative hub ’, where 90 % of the staff work together in a large space interrupted only by the open ‘ atrium cum auditorium ’ space with “ Google-esque ” steps and seating . An open , exposed steel frame structure and roof with glazed façades , envelopes the clustered rows of desks . There are no cellular offices - working space is totally egalitarian and flexible .
Sustainability From a sustainable design perspective , the building has a 4-Star GBCSA Building rating and a 5-Star GBCSA Interior rating , managed by Solid Green Consulting .
Passive design through East-West ‘ solid ’ façade orientation , reduced glazed exposure and small openings , work hand in hand with active design features such as the sun screening , insulated roofs ( heat and sound ), low energy lighting ( LED ) and air-conditioning ( VRV ), to make the occupancy comfort optimal .
