The Franklin Park headquarters building now has two 712V Aerotecture vertical-axis models.

The Living Building Challenge, run by the Cascadia Green Building Council, is growing in popularity these days. Referred to as one of the most advanced green building rating systems in the world, it's growing, I believe, in part because of its rigor.

Currently, four projects (see below) are racing to be the first to obtain Living Building Challenge certification.
The University of British Columbia’s Centre for Interactive Research on Sustainability (CIRS) will be a candidate to be regarded as one of the greenest buildings in North America once it is completed.
