Speaking about the lecture, RIBA President Sunand Prasad said:
"The RIBA is delighted that HRH The Prince of Wales will be delivering the 2009 RIBA Trust Annual Lecture as part of the Institute's 175th Anniversary programme of events," said Sunand Prasad, RIBA President.
"Both the Prince of Wales and the RIBA play a powerful role in raising national and international awareness about sustainability and the design of places and we hope this lecture will engage an even greater audience with these globally important issues.
We are looking forward to welcoming Prince Charles to the Institute for a lively and stimulating address."
