Green Building Council (USGBC) released its ranking of the Top 10 States for LEED-certified construction for last year.The per-capita list is based on 2010 US Census data and includes commercial and institutional green building projects that were certified throughout 2013.
USGBC calculates the list using per-capita figures measuring human intervention in constructing green buildings, allowing for a fair comparison of the level of energy efficient building taking place among states with significant differences in population and, accordingly, number of overall buildings.
