Welcome to our annual ranking of the greenest design firms in the region. These companies generated over $110 million in revenue designing projects within Arizona, Nevada and New Mexico that were officially registered with a third party rating system such as LEED or equivalent. The ranking is based on 2009 revenue and only includes projects that are being built with certification as a goal. This total is up from $88 million in 2008. Designers reported working on 230 projects that are seeking certification, down from 281 the year before.

While the number of licensed architects and engineers among the top firms plummeted from over 2,000 in 2009 to just 1,300 in 2009, the number of LEED-accredited professionals rose over 39% to 760.
