Star Design rating , and is currently applying for the equivalent As Built rating . A combination of sensible passive design principles and selected active technologies were used to minimise the impact of the building and its ongoing use on the environment .
These include the key design element of a floor-to-ceiling naturally-ventilated doublefaçade which provides inherent shading , prevents direct radiant heat entering the offices , and maximises day-lighting without glare . Integrated sun-responsive automated blinds modulate the internal environment and assist the HVAC performance .
The Solar PV Plant is a 107.97kWp grid-tied PV system made up of 354 x 305W Trina Solar modules . These are Tier 1 solar panels - Tier 1 suppliers own the entire value chain of their business to ensure quality and offer 20 to 25 year performance warranties .
There are 5 SMA string inverters which are the ‘ brains ’ of the system and control the flow of electricity from the panels to the building , converting DC current supplied from the modules to the AC for the use of the building . The system has an annual electrical output of approximately 180,000 kilowatt hours . The thermal storage HVAC system flattens the peak energy demand ,
