roaming guards . Each bui lding has a securi ty control room that caters for each individual bui lding. Edge accredi tat ion/s imulat ion was done wi th theoret ical resul ts for bui lding’s energy use, material use, and water use based on the post construct ion cri teria of the bui lding wi th favourable resul ts . Al l wet ser vices systems are des igned in accordance wi th Part XA of the Nat ional Bui lding Regulat ions , SANS 10400, which legi slates the des ign and instal lat ion of sustainable, energy ef ficient systems . Hot water i s generated via ai r-to-water heat pumps , which uses up to 66% less electrical energy than convent ional electric res i stance heat ing. Potable water pump systems were des igned by taking cogni sance of the ef ficiency of the pump motors and cons idering variable speed drive technology which reduces the pump dut ies and electrical usage in t imes of low demand. Low flow sani tar y fi tt ings were also part of the des ign to ensure a more sustainable development . The abovement ioned des ign principles have been implemented for both the res ident ial developments wi th s imi lar concepts for the commercial bui ldings . Local ly sourced materials were used as far as poss ible along wi th the use of local labour for various trades sourced through communi ty involvement processes and a CLO.
