I'd be happy to provide material that the Canada Green Building Council has about the LEED rating system, and platinum in particular. I wouldn't be able to speak in too much technical detail. I can say that from an energy use perspective, building to a LEED platinum standard gets you a greater than 60% improvement in energy performance of the building relative to the standard. But I can't speak to the products, durability, and that sort of thing. I'd be happy to facilitate the committee in accessing those documents from the Canada Green Building Council.
On March 26th, 2009. See this statement in context.
