XILINX ASIA PACIFIC HEADQUARTERS XILINX ASIA PACIFIC HEADQUARTERS Sustainable Industrial Building at every level By Joseph Goh, Project Engineer – M&E, Bovis Lend Lease 2 2008 • Issue 01 XILINX ASIA PACIFIC HEADQUARTERS XILINX ASIA PACIFIC HEADQUARTERS Bovis Lend Lease was engaged to manage the design and construction of the Xilinx’s new Asia Pacific headquarters in Singapore’s Changi Business Park n 2002 Lend Lease conceived and developed the commercial It is also Xilinx’s intention to create space where creativity can building 30 The Bond, the first commercial building to be be induced and interaction among employees encouraged at the awarded a five-star greenhouse rating in Australia by the workplace.

One such project in Asia is the Xilinx Asia Pacific Headquarters, which has been awarded Green Mark Platinum Award by BCA. This is a To ensure that the courtyards’ outdoor environment is first for a privately developed industrial facility in Singapore. comfortable for staff congregation and brainstorming sessions, Computational Fluid Dynamics (CFD) studies are conducted to ensure sufficient wind and acceptable Xilinx, a leader in the Programmable Logic Device (PLD) temperature can be achieved market which is one of the fastest growing segments of the semiconductor industry, has been listed as a Fortune 100 Best Companies to Work for since 2001 and it has not turned back since. It continues to strive for a working environment that is conducive for its employees and has achieved LEED (Leadership in Energy and Environmental Design) accreditation in its San Jose facility in the US. The same drive has motivated Xilinx to do the same wherever it operates, including its new Asia Pacific headquarters in Singapore. As part of Xilinx’s expansion plans, Bovis Lend Lease has been engaged to manage the design and construction of its new Asia Pacific headquarters in Singapore at Changi Business Park. One key design theme of the building is sustainability and the aim is to create a ‘green’ space that provides the most conducive work environment via practical means. Passive and active design features were explored. 2008 • Issue 01 3 XILINX ASIA PACIFIC HEADQUARTERS XILINX ASIA PACIFIC HEADQUARTERS Courtyard at Level 4 Another unique feature of the building is its double-skinned façade. The envelope thermal transfer value (ETTV), a mandatory calculation indicating the performance of the building envelope in heat transfer from outside, has achieved a low of 38.53 W/m2 (Singapore code requirement calls for a maximum of 50W/m2). Aesthetically, Xilinx Asia Pacific headquarters also appears outstanding at Changi Business Park where most buildings are clad in green or blue façades. Tasked to ensure the incorporation of sustainable technology at Xilinx’s new headquarters, Bovis Lend Lease, with its consultants, proposed green features that enabled a mere 1.1% increase in construction investment to reap an estimated savings of S$500,000 each year.

Creative design from the outdoor air takes place at the centralised location to maintain the humidity is and condensate water can be easily collected. This is normally introduced by installing pre- channelled out of the building as wastewater. In Xilinx’s facility, cooled AHUs with heat pipes however, condensate water is collected, filtered and recycled to bring in the outdoor air. This for landscape irrigation. In Xilinx’s facility, design reduces the size of the condensate water is desiccant dehumidifier used for collected, filtered and humidity control and decreases Recycled Chips for Signage recycled for landscape the operating period resulting in irrigation significant energy savings. Xilinx recycles its unwanted chips to turn them into usable signage in the building, thereby cutting down on waste Lighting Management generation. Signages are found on every level of the new Asia Pacific headquarters building, and they are all made of discarded chips from the production line.
