My company's office is now rated as LEED Silver, for its daylight-sensitive lighting controls, reuse of existing building features, energy-efficient AC design, low VOC paints, recycling points, local bike parking scheme, wind power subsidization and a whole host of other environmentally sensitive improvements. I worked on the project team from its earliest days when we were choosing a new office, through to the engineering design and then later the LEED accreditation, so a full concept-to-completion cycle over two and a bit years.
The award is for 'Commercial interiors' where we've moved into two floors in a large building, but I have two more projects in the pipeline that are much, much bigger, and where the energy efficiency and environmentally sensitive design will make a really big difference. And I'm just getting started, honest.
More about LEED.
Congratulations! I'd be quite interested to hear more about the sort of stuff you're up to, but I realise that I might not be in the centre of your key audience demographic :-)
