ASTM International defines building performance as the in-service functioning of a building for a specified use ASTM E1480-92. The term refers to how effectively, safely, and efficiently a building performs its mission at any time during its life cycle. A buildings performance state, which changes during time in service, is reflected by two different indicators the physical condition state and the functionality state. The physical condition state relates to a facilitys general physical fitness, independent of its mission, as it deteriorates due to routine aging, excessive or abusive use, or poor maintenance. The functionality state relates to the facilitys suitability to function as intended and required for the mission. The functionality state is distinct from, and determined independently from, the physical condition state. Condition-based metrics such as the Condition Index CI have been used by the Army for decades, but a companion index of functionality was not developed at the same time. However, to fully describe a buildings fitness for changing missions over its entire life cycle, a quantitative and objective Functionality Index FI is needed.
