Costs on the 2012 Olympic stadium and aquatics centre are likely to rise further after a recommendation by the Games鈥� sustainability watchdog that their cooling systems be reworked
Shaun McCarthy, chair of the Commission for a Sustainable London 2012, said the Olympic Delivery Authority (ODA) was in danger of 鈥渟poiling a very good job鈥� if it pressed ahead with plans for chillers that use high carbon-emitting hydrofluorocarbons (HFCs). The commission first recommended these plans be reviewed in 2007.
He said: 鈥淚t would cost more, but I鈥檓 unsympathetic because if they had done it when we recommended it, that wouldn鈥檛 be the case. You can鈥檛 be the most sustainable Games in history if you have HFC cooling in your aquatics centre.鈥�
Meanwhile, 拢19m has been released from the contingency fund to beef up the security of venues.
The ODA said: 鈥淲e are still looking at the issue of cooling systems.
This is not about costs but about the technical challenges of alternatives to HFCs, which can be toxic and explosive.鈥�
