This year's World Architecture Festival is heading towards its conclusion in Singapore, with the announcement of the World Building of the Year due in a few hours' time. It is a truly international event, with delegates from 68 countries and a great spread of projects yet, like last year, the greatest interest comes from Singapore itself.
This is not just in terms of the many excellent projects that have been submitted from the city state, but also in the insight offered into the way it works. With its dense population, Singapore is determined to preserve and enhance quality of life. So, in new areas like Marina Bay, there is a policy of 100% minimum replacement of ground - in other words, at least the footprint of vegetation that has been destroyed by construction has to be replaced on the building's roofs and balconies.
The Singapore Sports Hub, now taking shape,is extraordinarily compact for such a facility, yet still manages to have a stadium that is a bravura feat of engineering, with the world's largest spanning opening roof, and local cooling of seating that can be zoned so that only those areas that are actually used will be cooled.
The funding is equally innovative, a public private partnership into which the government will inject operational money for community sports.
What an amazing place Singapore is . Now all it needs to do is sort out the ferocious nature of the air conditioning, which seems to give the lie to all the claims for sustainability.
