Green buildings, energy savings, and sustainable designs continue to be the hottest topics in the real estate and building industries.  But if you own, manage or invest in existing buildings, do you sometimes wonder how to take advantage of this dramatic movement?  If so, there is good news.

The US Green Building Council (USGBC) recently released its latest (January 2008) certification update for existing buildings.  For a number of years now, the council’s increasingly adopted Leadership in Energy and Environmental Design (LEED® ) rating system has been available in versions that apply to New Construction (LEED-NC), Core and Shell construction (LEED-CS) and Commercial Interiors (LEED-CI).  The updated program for Existing Buildings (LEED-EB) applies specifically to the operations and maintenance of those buildings.  So what does that mean?

The USGBC defines the Existing Buildings rating program as a “set of voluntary performance standards for the sustainable ongoing operation of buildings not undergoing major renovations.” Essentially, the system provides sustainability guidelines for building operations, system upgrades, space-use changes, and building processes.

In other words, this particular version of LEED addresses all of the day-to-day operations and management issues of a building.  It is not dependent on design and construction or renovation work.  That means any building can pursue certification anytime because many of the criteria can be met by establishing and carrying out policies and procedures that don’t necessarily require capital improvements.
