LEED certification is not reserved for new or improved buildings; the U.S. Green Building Council's Leadership in Energy & Environmental Design also has a commercial interiors category. LEED-CI certification looks at environmentally friendly office spaces.
" LEED for Commercial Interiors is the green benchmark for the tenant improvement market. It is the recognized system for certifying high-performance green interiors that are healthy, productive places to work; are less costly to operate and maintain; and have a reduced environmental footprint."

An office space can achieve one of four different levels of LEED-CI certification. To be recognized as LEED-CI certified, the project must score between 21 and 26 points. LEED-CI Silver certification is awarded to projects receiving 27-31 points. LEED-CI Gold certification requires 32-41 points and the highest honor, LEED-CI Platinum certification requires a minimum of 42 out of 57 total available points.
While most of the categories have strict requirements, the Innovation & Design Process allows buildings to receive recognition for items not included in the other sections. The use of a LEED Accredited Professional on a project qualifies for one of five total points.
Points in the Innovation & Design Process category are awarded to projects that "substantially exceed a LEED performance credit such as energy performance or water efficiency." Additionally, interior spaces that "apply strategies or measures that are not covered by LEED such as acoustic performance, education of occupants, community development or lifecycle analysis of material choices" may receive points in this section.

There is no better match for a LEED certified building than a LEED certified office interior. Office interiors that received LEED-CI certification can truly be called a green office.
