Just tried this offer from the City of Vancovuer this weekend at the Olympic Village. You can listen to those recordings via your phone (call 604.673.8150 when you are standing in front of one of the buildings) or you can listen to it online on the Green Building Audio Tours website ..

Green building audio tours are audio guides to Vancouver’s green buildings. Each three-minute recording takes the listener on a virtual ‘tour’ of the building’s green design features, guided by the architect or member of the design team. The Vancouver Green Building Audio Tours were created through a partnership between City of Vancouver Sustainability Office and the Open Green Building Society. Keep your eyes peeled for audio tour signage around town.
