As the 2012
Summer Olympics in London draw to a close we consider it; The
Greenest Games Ever. Following nine years of planning towards minimizing the
carbon output it seems that the initial target; 20% of energy generated from
on-site renewable sources was too ambitious for this scale of event. Despite not having achieved this target the
sustainability efforts have set new standards for large-scale events to build
upon.
Sustainability
was a key driver in the design and construction of Olympic Games Venues. Not
only is the Olympic Park a regeneration site but all new construction was
designed to embody carbon. Before works began 2 million tons of soil from the
wasteland was decontaminated and reused to create the lush park that you see
today with trees, flowers and wetlands supporting biodiversity.
Temporary structures were built from materials that will be reused/ recycled after the games. Such as; The baseball arena, which is essentially a huge tent. The steel frame and PVC cover can be dismantled and reused. Permanent structures have also been designed to be used for many years after the Olympics and they too contain embodied energy, for example;

·
The Copper Box
(used for handball, martial arts and wheelchair rugby) is equipped with 88
light pipes, filling the inside of the building with natural light during the
day. The outside is made from largely recycled copper cladding, and the sloped
roof collects rainwater for the toilets, reducing the building's water
consumption up to 40%.
·
The Aquatics Centre
was constructed with 50% recycled material. It has two removable wings to
accommodate up to 17,500 people and will be used as a public facility after the
games.
·
The Velodrome contains
sustainably sourced timber. The passive solar design allows the building to
utilize natural light during the day to reduce energy consumption. The building
also uses natural ventilation eliminating the need for air conditioning and collects
rainwater to reduce water consumption by up to 70%.
Sustainability was also a priority for the London 2012 organizing committee and all efforts were made to minimize the environmental impact during the Olympics, including;
·
Ticket-holders
receive a one-day pass for public transportation, had access to trails in the Olympic
Park and reduced rates for England's coach and train services.
·
All food packaging
at the events is recyclable which will considerably reduce waste as an expected
14 million meals are to be served at the events. Overall, the 2012 Summer
Olympics aims to recycle 70% of the anticipated 8,000 tons of waste produced at
the events.
· Biomass boilers,
solar panels and wind turbines are used throughout the park. Although these
technologies have not produced the original target of 20% they are now expected
to produce about 9% of the overall energy consumption.
