−	The London Aquatics Centre was in full Olympics mode during the 2012 Games. But the ~~centre’s~~ innovative, eco-friendly building services design also provides a lasting energy-efficient facility for the nation. Like its neighbouring athletics stadium, the London Aquatics Centre was designed to provide a lasting Olympics legacy for the capital and the nation. The centre permanently accommodates 2,500 spectators, making it the largest swimming venue in the UK. During the Olympics the addition of two temporary, covered stands will provide a further 15,000 seats.	+	The London Aquatics Centre was in full Olympics mode during the 2012 Games.

−	The Olympic Delivery ~~Authority’s~~ energy strategy requires that the centre is able to demonstrate an overall 50% carbon emission reduction on current Building Regulations (2006 at the time). Like other venues on site, the centre has to be integrated into the Olympic ~~Park’s~~ energy centre (see the article on the energy centre in the ~~[http://www.cibsejournal.com/archive/2011-08/power-behind-the-glory~~ August 2011 Journal, page 16]).	+	The Olympic Delivery Authority's energy strategy requires that the centre is able to demonstrate an overall 50% carbon emission reduction on current Building Regulations (2006 at the time).

	The large volume of the main pool hall, which measures 180,000 sq m, required a unique approach for controlling the indoor environment. A series of microclimates has been created within the hall to achieve the right comfort conditions while minimising energy consumption. This microclimate solution also uses temporary systems when the centre is expanded for the Olympic and Paralympics Games.

	The involvement of building services engineers in the very early stages of the design, not only in systems selection but in the use of building physics, was the key to achieving the 16.5% savings in carbon using efficiency measures alone, before applying renewable energy sources.
