The early evening event, well organised by the ODA, was very different. 1,600 guests were invited to celebrate one year to go with the first dive into the pool by Tom Daley and a unique swimming race featuring medal winning athletes, but most of them not for swimming. All I can say about that is that as a swimmer, Tessa Sanderson throws a mean javelin. From a sustainability standpoint it was mixed. The audience was very inclusive, lots of local school kids and local residents who responded to advertising in the local media. All races, colours and abilities seemed to be there and very few white blokes in suits (like me). However I was disappointed to see naff plastic flags on every seat which served no useful purpose at all and just littered the venue after the event. I have no idea what they were made of, where they were made and where they will go when somebody has swept them off the floor. Our commissioner Neil Taylor took a load home for his kids so I suppose that is re-use of a sort. The food was healthy and fresh (and free), served on cardboard platters with wooden forks. However there was far too much and much was wasted. I was not impressed with what I saw of the waste management either, all waste in one bin with no evidence of segregation. All lessons to be learned for The Big One next year.

A final word for the Aquatic Centre. We have been very rude about this building and have been unstinting in our criticism of its relative lack of sustainability. I still think 3,000 tonnes is too much metal to put a roof over a swimming pool but the building is stunning inside. The atmosphere created by 17,000 spectators will be an inspiration. However, I still prefer the velodrome!

We have seen the case for chilling in the velodrome and we accept that there is a strong case for HFCs here. The building has many sustainable features including low embodied impacts and mostly natural cooling. The cooling load is very small compared to other venues.

But what about the other venues? The ODA has fantastic process for managing their objectives but there is no policy for refrigerants despite our recommendation that there should be in our report of November 2007. In this case designers will revert to type and design things the way they always have done.

We think it is time for the ODA to declare a “chiller amnesty” with their designers to establish exactly what is planned. It should be possible to look at these on a case-by-case basis but time is running out, this needs to be done very soon.
