This commercial development at 64 Allara Street, Canberra CBD, comprises of four office levels and three basement carparks.  Designed to achieve a 5 Star NABERS rating and 5 Star Greenstar rating for the base building, it is served by a central roof mounted air cooled chiller system comprising of multiple low temperature chilled water chillers sized for the cooling and dehumidification of the primary air systems. The system also includes a heat exchanger and high temperature chilled beam circuit.

Cooling distribution for the open-plan office areas are provided by a variable 100% fresh air primary air solution distributed through adjustable swirl ceiling outlets mounted on the perforated tile ceiling, and passive chilled beams reticulated via a reverse return pipe system suspended in the ceiling void concealed by the perforated ceiling. The building heating is served by a central roof mounted, natural gas fired heating water system comprising multiple modulating condensing hot water boilers.
