overlap between each louvre. The design team used optimisation software to achieve the best fit for these constraints and at the same time minimise the physical area of louvre fabric.
Sustainable Design Sustainability has been central to the design of Sports Hub since the outset. The site location is close to the cen- tre of Singapore and benefits from access to two mass rapid transport (MRT) stations. So at a macro level the best efforts have been made to minimise the environ- mental impact of this sports precinct, as Lewis outlined: “Our initial challenge was to make the stadium as effi- cient as possible in energy terms. Passive design solu- tions were targeted first — shading to seating, insulation to roof cladding, and giant louvers meant that solar heat gain to the interior of the stadium was reduced. “We then looked at ways we could reduce the peak
energy demand for the bowl cooling system, which was required to meet the comfort criteria set out in the design brief. There were two main decisions to be made: 1) Whether to fully enclose the roof to achieve the com- fort criteria required; and 2) whether to utilise an ‘under seat’ or an ‘over head’ cooling system.” Lewis continued: “Our preliminary analysis showed
that the ‘under seat’ cooling would provide the best solu- tion in terms of spectator comfort and the decision over whether to fully enclose the stadium envelope was quick- ly made based on energy terms. When we benchmarked our design against existing stadiums in Japan and the USA it was clear that our naturally ventilated stadium
bowl with localised cooling will use a fraction of the ener- gy of an equivalent fully enclosed stadium.” (Please see Figure 7.) Lewis concluded: “With the stadium at the centre of
the precinct, we realised that an efficient solution need- ed to balance the intermittent energy demands of the stadium with the everyday energy demands of the sur- rounding buildings, and to explore the benefits of inte- grating the systems serving both. The final design solution integrates thermal storage tanks into the design, which are pre-cooled before an event and allow for the peak demands of the stadium seating to be met from the same plant that provides the everyday cooling to the adjacent office, retail, indoor arena and aquatics centre. “The additional energy required to switch on the
bowl cooling for a stadium event will be offset by energy harnessed throughout the year from a large photo volta- ic array, meaning that the operation of the bowl cooling to the stadium will have a zero carbon impact on the environment. The Sports Hub Consortium’s dedication to achieving a sustainable design for the stadium and the Sports Hub precinct was recognised at a recent awards ceremony in which the Sports Hub was awarded ‘Green Mark Gold Plus’ status.” ✪
Clive Lewis, Associate Director with Arup Associates, is the lead sports designer working on the Sports Hub responsible for the design of the new National Stadium, Aquatics Centre and the two Multi-Purpose Indoor Arenas. Since joining Arup in 2003, Clive has worked as lead sports architect on the Donbass Arena in Shakhtar (host stadium for the UEFA 2012 European Cup) and the Beijing National Stadium (Beijing Olympics 2008).
