BEAM Plus Existing Buildings (EB) measures the actual performance of a building and evaluates its facility management practices. The assessment covers all aspects of management, operation and maintenance, and may be initiated at any time during a building’s operational life.

To help achieve the target of the Hong Kong Government’s stated Energy Saving Plan by 2025, the new version of BEAM Plus Existing Buildings V2.0 contains major revisions to the assessment guidelines and offers greater flexibility in the scope of assessment. These changes have been implemented with a view to encouraging more participation by the 42,000 existing buildings in Hong Kong, thus improving their energy efficiency and enhancing their environmental management practices.
