extraction, sump pumps as well as the fire and security systems. Minimisation of greenhouse gas emissions associated with operational energy consumption is reduced. An energy model of the building was generated and in the design stages of the building compared to a notional building model. The building design showed an improvement over a SANS 10400 notional building. The building is designed to achieve an energy consumption of approximately 209,5 kWh/m 2 /annum which amounts to over a 60% improvement of energy use when compared to the notional building. There are potential carbon saving of 251,4 kgCo2 per year compared to a notional building. SITE PLAN standing and managing building systems and to assess opportunities for energy savings. The wireless bleedingEdge Building Telemetry System allows for intuitive access via apps on tablets and smart phones. Users can control and monitor the air conditioning system, lifts, generators, UPS installation, extract fans, basement smoke Water Saving Initiatives The water system is estimated at saving ±30% translating to ±2,742kl of water saved per annum. The building achieves savings through the use of water efficient fittings that limit the occupant water usage. Sub-metering of major water consuming systems is in place. Gathering information is key to understanding and managing building systems and to assess opportunities for water savings. The building is designed to reduce the consumption of potable water for the building’s fire protection and essential water storage systems.
