How do you find LEED compared to the local/Aussie system? I like that the whole LEED 'ecosystem' is more mature, but US customary units annoy and confuse me. It seem that the sheer volume of LEED material out there makes it worth spending more time getting familiar with it, though.
I don't want to go too far into that on this forum ('cos I'll probably have to break the rules by discussing politics!), but you hit the nail on the head when you say that LEED is more mature - the massive number of LEED buildings going up around the world results in more feedback on what works and what doesn't, allowing for better optimization of the system itself. LEED is also starting to place more emphasis on the commissioning and proof that the building is really performing in reality and not just on paper.
That said, there is definitely room for a local rating tool that addresses the uniquely South African issues. We went across to Australia to talk to their GBC and understand where their Green Star (and therefore a lot of the South African one) came from and where it's going. Even with that background info, I can't say that one tool is better than another - you select the tool that's most appropriate for the project. In my experience so far, it all depends on whether the company is marketing the building locally or internationally, with the technical aspects being secondary in the decision process...
I hear you on the American units! They're getting better though, and we've been submitting projects in metric units without any problems.
