Abstract ‘Legacy’ is the concept that underlies the sustainability agenda of the London 2012 Olympic and Paralympic Games, embracing temporary infrastructure and venues to leave behind a vibrant, productive community with world-class, affordable sporting facilities. The Aquatics Centre, developed as an architectural icon, was the most complex venue constructed on the Olympic Park. This case study explores the integration of sustainability into the Aquatics Centre, providing a balanced view of the venue’s sustainability credentials and considering its contribution to the sustainability agenda beyond the boundaries of the Park. The Aquatics Centre London’s bid to host the 2012 Olympic and Paralympic Games presented a comprehensive vision for the first sustainable Games. In 2007, the Olympic Delivery Authority (ODA) embodied this commitment in its sustainable Development Strategy. The Aquatics Centre’s design featured in the bid, with an iconic wave-like roof defining the gateway to the Park for the majority of visitors. Temporary seating structures provide a 17,500-seat Games-time capacity for the venue. After the Games these are replaced by a 14-metre-high cantilevered glazed curtain wall, reducing capacity to a legacyappropriate 2,500 and flooding the interior with natural daylight.

Owner approach of sustainability
The concept of the London Aquatic Center in the environmental approach of the organizers: to build permanent structures to the extent that they found a use after the event, and to build temporary structures in the opposite case.
Thus, only the central building will be part of the Olympic legacy: an aquatic center with a capacity of 2,500 seats. The wings which shelter the removable stands of 17,500 places during the competition could be disassembled after. Composite materials will be re-used in the UK as new tensile structures.
Architectural description : Design Concept The architectural concept of the London Aquatics Centre is inspired by the fluid geometry of water in motion, creating spaces and a surrounding environment in sympathy with the river landscape of the Olympic Park. An undulating roof sweeps up from the ground as a wave - enclosing the pools of the Centre with its unifying gesture of fluidity, whilst also describing the volume of the swimming and diving pools.
The London Aquatics Centre is designed to have the flexibility to accommodate the size and capacity of the London 2012 Olympic Games whilst also providing the optimum size and capacity for use in Legacy mode after the 2012 Games.
The podium element allows for the containment of a variety of differentiated and cellular programmatic elements into a single architectural volume which is seen to be completely assimilated with the bridge and the landscape. The podium emerges from the bridge to cascade around the pool hall to the lower level of the canal.
The pool hall is expressed above the podium level by a large roof which arches along the same axis as the pools. Its form is generated by the sightlines for the spectators during the Olympic mode.
Double-curvature geometry has been used to create a structure of parabolic arches that define its form. The roof undulates to
differentiate the volumes of the competition and diving pools, and extends beyond the pool hall envelope to cover the external areas of the podium and entrance on the bridge.
The roof structure is grounded at three points of the centre (two points at the northwest end on the bridge; and one single point to the south east end). This structural arrangement ensured 7,500 temporary spectator seats could be installed along either side of the pools in Olympic mode (total 15,000 temporary seats) with no structural obstructions.
After the 2012 Olympic and Paralympic Games, this temporary seating has been removed and replaced with glazing panels, leaving a capacity of 2,500 seats for community use and future national/international events, with a significantly reduced pool hall volume.

Solutions enhancing nature free gains : optimisation of the main roof geometry to balance the benefit of passive solar heating and the risk of summer overheating
Smart Building BMS : The main pool hall is naturally lit, the pool tanks are insulated, and an adaptable environmental control system allows ventilation to be customised within specific areas of the large volume space. This gives the building’s operators the option of avoiding excessive use of mechanical ventilation in areas where it isn’t needed.

Life Cycle Analysis Based on EVEA's Life Cycle Analyzes, roof and wall recycling via Texyloop® has reduced environmental impacts by 50%, producing 23 tonnes of 2nd generation raw materials. Material impact on GHG emissions : 50,00 Eco-design material : We substantially reduced the carbon footprint of the London Aquatics Centre by primarily using secondary aggregates and cement replacement material – in essence, recycled rather than ‘new’ concrete.
We were the first team designing 2012 Olympic venues to push beyond the standard supplier offering of 50% coarse aggregate substitution. In the end, more than 75% secondary aggregates were used in some concrete mixes to offset limestone aggregates used for the pool tank. We exceeded targets set by the ODA, with concrete contributing just 3% to the building’s carbon footprint.
We were awarded a BREEAM Innovation Credit for our use of concrete mixes.
Over 150,000 tonnes of concrete was used in the Aquatics Centre and the integrated pedestrian bridge. The dedication of the team in maximising the sustainability of the concrete achieved over 4,000 tonnes of embodied CO2 savings and substitution of over 29,000 tonnes of primary aggregate, equivalent to 28 per cent of the total.
In total, over 80 per cent of the 235,000 tonnes of loose aggregates used were from a recycled source, a significantly higher percentage than any other venue on the Park. Temporary stands enclosed with phthalate-free PVC.
The majority of recycled aggregate was construction and demolition waste from elsewhere in the London area. A further 23,000 tonnes was obtained from the site-wide soil hospital which created blended engineering materials from the soil-washing remediation process.
Water management Consumption from water network : 40 000,00 m3 Consumption of grey water : 2 700,00 m3 Water Self Sufficiency Index : 0,06 % Water Consumption/m2 : 0,93 m3/m2 Water Consumption/Shower/day : 2,29 m3/Shower/day To reduce the building’s potable water demand by more than 40% (against standard designs), we developed a system that uses backwash water from the swimming pool filtration plant to flush urinals and toilets.
Further savings were achieved via lowflow sanitary fittings. With greatest demand for potable water coming from showering, incorporating low-flow showers and basins delivered 35% potable water saving. Rainwater harvesting was also incorporated into the design, with harvested water used to irrigate the green wall at the southern end of the building.
Indoor Air quality Indoor Air quality : We made extensive use of measures to maximise energy efficiency, including high levels of insulation and envelope air tightness, low velocity ventilation systems with high efficiency heat recovery, and water based heating systems with variable speed pumps. An Ammonia chiller plant provides space cooling and-uses rejected heat for pool water heating.

// Urban Environment
The London Aquatics Centre is located at the south eastern edge of Queen Elizabeth Olympic Park on the new Stratford City Bridge giving pedestrian access to the park from the new Stratford City development and public transportation.
The Aquatics Centre is planned on an orthogonal axis perpendicular to the Stratford City Bridge. Along this axis are laid out the three pools.
The training pool is located under the bridge whilst the competition and diving pools are within a large volumetric pool hall. The overall strategy is to frame the base of the pool hall as a podium by surrounding it and connecting it into the bridge.
Land plot area : 21897 m2
Built-up area : 75 %
Parking spaces : There are 111 Pay & Display car parking spaces in the car park located next to the London Aquatics Centre.
Otherwise, there is plenty of parking available in nearby Westfield.
There are more than 140 cycle racks outside the London Aquatics Centre, including a Santander Cycles docking station located outside the centre

The London Aquatic Center symbolizes the environmental approach of the organizer: build permanent structures if they can be used after the event or temporary, where appropriate. Thus, only the central part (2,500 places) is preserved as Olympic legacy. The wings, which offeredadditional capacity of 15 000 seats, are today dismounted. Composite materials used for the roof and outer walls have been removed, packaged and shipped at Texyloop, to generate raw materials of second low environmental impact generation. [non final version]
