This Recommendation specifies a methodology for assessing and scoring, and subsequently improving, the sustainability performance of existing office buildings. The methodology described in this Recommendation provides building owners, managers and operators with a consistent framework to critically assess the sustainability performance and management of office buildings in 10 key areas: energy; water; air; comfort; health and wellness; purchasing; custodial; waste; site; and stakeholders.

It should be noted that the methodology proposed in this Recommendation applies only to existing office buildings and not to the construction of new buildings.

NOTE – This Recommendation is based on the BOMA BEST Sustainable Buildings assessment programme [b-BOMA].
