This International Standard provides requirements for determining and reporting a carbon metric of anexisting building, associated with the operation of the building. It sets out methods for the calculation,reporting, communication, and verification of a set of carbon metrics for GHG emissions arising from themeasured energy use during the operation of an existing building, the measured user-related energyuse, and other relevant GHG emissions and removals. These carbon metrics are separated into threemeasures designated CM1, CM2, and CM3 (see 5.1.1).This International Standard follows the principles set out in ISO 15392 and those described in Clause 4.Where deviations from the principles in ISO 15392 occur, or where more specific principles are stated,this International Standard takes precedence.The carbon metrics CM1 and CM2 are not quantified based on life cycle assessment (LCA) methodology.Carbon metric CM3 may include partial quantification based on the results of LCA.This International Standard does not include any method of modelling of the operational energy use of thebuilding but follows the conventions provided by other International Standards, as given in relevant clauses.This International Standard is not an assessment method for evaluating the overall environmentalperformance of a building or a building-rating tool and does not include value-based interpretation ofthe carbon metric(s) through weightings or benchmarking.This International Standard deals with the application of the carbon metric(s) for an existing building,either residential or commercial, or a building complex. It does not include provisions for regional and/ornational building stock.
