Across the country, an emerging trend is seeing existing and older buildings being retrocommissioned as environmentally-friendly structures. Nearly 500 are awaiting LEED certification.
The trend toward retrocommissioning existing commercial structures using green building principles is quietly taking shape behind the louder activity of the new construction sector.
