Daylighting The main office and circulation spaces are glazed using full-height Low-E curtain walls to provide maximum daylight penetration and enables energy efficient lighting systems within the spaces. Perimeter lighting fixtures are controlled by daylight sensors which reduce energy consumption by automatically switching off lamps when adequate daylight is available. Secondary rooms are also fitted with operable windows for natural ventilation and daylight. Bioswale Natural filtration and drainage systems are used to reduce the burden of surface run off to the public drainage system. They also act to collect surface run off for reuse in the central irrigation system. The project’s sustainable drainage strategy also includes the use of permeable grass pavers for all ground level car park areas. These systems allow rainwater to replenish the site’s local aquifer rather than being diverted into an external storm-water drain. Rainwater Harvesting Siphonic rainwater down pipes are used for high velocity rain-water run-off from the building’s roof. This rainwater is channelled into a collection tank with a capacity of 100 cubic meters. The tank is made of 100% recycled content materials. Collected rainwater is filtered and reused to irrigate softscapes around the building and cater for the water requirements of the vegetated green wall via an integrated gravity-fed rooftop irrigation system. The project’s rainwater harvesting system has been designed to ensure that no potable water is used for irrigation purposes. Air Conditioning The project utilizes a highly efficient dual-mode air and water cooled chiller system with multiple zoning FCU and precision air-conditioning in the data centre areas. Zoning of FCU creates savings in Energy requirement due to variations on zoning usage. The cooling requirements of the data centre are further optimized via an innovative ‘cold aisle containment’ system. This system establishes targeted cooling zones that meet the requirements of specific equipment rather than expending the energy otherwise required to cool rooms uniformly. Lighting Light fittings are energy efficient Florescent T5 using low loss electronic ballasts and LED lighting. These offer higher luminance levels and their zoning enables energy conservation through specific usage requirements. This system is bolstered through the use of occupancy sensors, daylight sensors and control via the central Building Automation System. Renewable Energy An array of photovoltaic panels is installed on the building’s uppermost roof area. Mounted on a steel trellis, the 234 m2 PV array generates electricity on site with all power generated feeding directly back into the municipal power grid. This renewable energy production helps offset the intensive energy demands of the data centre operations. Lifts Lifts incorporate AC VVVF control and gearless motor drives with synchronous motor and permanent magnets and are fitted with detection sensors, sleep modes and energy saving light fittings. Indoor Air Quality There are minimum requirements for ventilation rates in accordance with ASHRAE 62.1:2007 which are designed to enhance the comfort and well-being of the occupants. Strict use of low-VOC coatings, paints and adhesives further reduce detrimental impact on occupant’s health from finishes that emit internal air pollutants. Sanitary Fittings Dual Flushing WC’s are fitted allowing control of water volume based on different usage needs. All basin taps and other sanitary wares are water efficient fittings with certified WELs ratings of 3-tics (maximum efficiency rating). In addition, waterless urinals are specified in the male toilets, further reducing water consumption. Overall use of potable water within the building is reduced by more than 50%. Sustainable Transportation Regular shuttle service is provided between the building and the Batu Tiga KTM station (1.6km away) in order to encourage employees to commute via public transportation. Preferred parking for carpools is provided adjacent to the building’s main entrance.
