Olympic Aquatics Centre uses eco-friendly cooling

But other venues cling to systems harmful to the climate.

But other venues cling to systems harmful to the climate.

While all eyes have been focused on the action in the pool, behind the scenes, the Olympic aquatic sports venue is also leading the way in environmentally friendly cooling systems, London-based Environmental Investigation Agency (EIA) revealed in a communiqué.

Designed by Zaha Hadid, the Aquatic Centre in London uses ammonia, one of a number of “natural” refrigerants that have either no or low global warming potential. This not only eliminates the need for HFCs, but also leads to greatly improved energy efficiency, EIA revealed. In addition to the Aquatics Centre, the Olympic Energy Centre also uses ammonia refrigerants, it added.   Alasdair Cameron, Global Environment Campaigner with EIA, said: “It is fantastic to see the London Olympics waking up to the need to use environmentally friendly refrigerants as a means of reducing its carbon footprint, but this is just the start. The next step will be to build on this experience so that future events, such as the Commonwealth Games in Glasgow can be completely HFC-free.”   However, despite the positive signals being sent by the use of natural refrigerants in the Aquatics and Energy centres, other venues have failed to rise to the challenge, with the Olympic Stadium and media centres relying on HFC-based equipment, EIA pointed out. It highlighted that refrigeration and air conditioning are a major source of greenhouse gas emissions, partly through the use of synthetic refrigerant chemicals called hydrofluorocarbons (HFCs) which are often thousands of times more potent than carbon dioxide.

Globally, HFCs account for about one per cent of all greenhouse gas emissions, and this could rise to nearly 20% by the middle of the century, unless urgent action is taken, EIA warned.
