building-level functionality assessment or facility performance evaluation (FPE) and indexing approach captures
both qualitative issues and quantitative functionality-loss metrics
that affect facility performance relative to its mission.
This approach considers 14
comprehensive functionality categories, listed below, that relate to
user requirements, technical obsolescence, codes, laws, and
The extent to which a facility fails to meet these categories (ie., functional obsolescence) is identified by the functionality gap and functionality index (FI).
- Location – suitability of building location to mission
- Building Size/Configuration – suitability of building
size and layout for the mission;
- Structural Adequacy – capability of
structure to support seismic, wind, snow, and mission related loads;
- Access – capability of building to support entry, navigation, and
egress as required by mission;
- Level of compliance with the
legislation governing barrier free access.
- AT/FP – compliance with
DoD anti-terrorism/force protection requirements.
- Building Services –
suitability of power, plumbing, telecom, security, and fuel
- Comfort – suitability of temperature,
humidity, noise, and lighting for facility occupants;
- Efficiency/Obsolescence – addresses energy efficiency, water
conservation, and HVAC zoning issues;
- Environmental/Life-Safety –
addresses issues such as asbestos abatement, lead paint, air quality,
- Missing/Improper Components – availability and
suitability of components necessary to support the mission;
- Aesthetics – suitability of interior and exterior building appearance
for the mission;
– ease of maintenance for operational equipment;
- Cultural Resources
– historic significance and integrity issues that impact utilization
