The building has been designed to be a low carbon and sustainable building. The shape of the building has been designed to reduce the effects of wind, thereby reducing the necessary size and weight of the structure. In addition to fundamental passive measures such as orientation, sustainable building systems have been incorporated into the design which address issues such as comfort, maintenance and cost while paying due regard to environmental sustainability and energy conservation. These include: solar thermal hot water; air-side energy recovery; heat recovery chiller; ice storage system; desiccant dehumidification; high-rise air discharge pressure CFD analysis; free cooling system; and variable air volume.
