The economic life of an asset is the period during which it remains cost-effective to operate and

maintain, minimizing total ownership costs.
Economic life (D) is determined by evaluating operating expenses, maintenance costs, depreciation,
and efficiency. At this stage, the asset provides maximum value before its costs exceed its benefits.
Ownership life (A) refers to the entire period of possession, which may extend beyond its optimal
cost-effective period.
Useful life (B) is the estimated time an asset can be functionally used, but this does not always align
with cost efficiency.
End of life (C) marks when an asset is no longer usable, often requiring costly disposal or
replacement.

Quality in a facility is ultimately defined by the customer (D). While facility managers and service

providers establish service standards and operational efficiencies, the end-users’ experience and
satisfaction levels dictate whether a facility is meeting quality expectations.
IFMA Core Competency: Performance and Quality Management emphasizes that facility managers
must align facility operations with customer expectations to ensure service excellence.
ISO 41001 and EN 15221-3 standards highlight that quality should be measured based on customer
feedback, performance metrics, and compliance with service level agreements (SLAs).
Facility Manager’s Role (A): Responsible for implementing and managing quality programs but does
not independently define quality.
Service Contract Provider’s Role (B): Ensures service delivery but follows predefined standards.
Facility Team’s Role (C): Supports quality initiatives but does notsolely determine the standard of
quality.

Installing sub-meters for each department (D) is the most equitable way to ensure accurate and fair

distribution of electrical costs. Sub-metering provides real-time, precise measurement of energy
consumption by each department, ensuring that they are only charged for what they actually use.
Advantages of sub-metering (D):
Encourages accountability and energy conservation.
Ensures fair and accurate billing.
Allows facility managers to monitor and optimize energy use.
Comparison with Other Options:
Net area occupied (A): Does not account for actual energy consumption—departments with energyintensive equipment would be unfairly subsidized by those with lower usage.
Negotiating chargeback rates (B): Creates inconsistency and potential disputes; lacks transparency.
Headcount-based charging (C): Fails to consider that energy usage varies based on equipment, not
just the number of people.

Facility managers use ASTM/IFMA standards when determining the assignment of floor area for

occupant groups. The ASTM International (formerly American Society for Testing and Materials) and
the International Facility Management Association (IFMA) have developed specific standards for
space measurement and allocation to ensure consistency and efficiency in facility planning and
management.
ASTM Standards: ASTM E1836 and ASTM E2570 provide guidelines forspace measurement in
commercial and office spaces, ensuring accurate calculations of usable and rentable areas.
IFMA Standards: IFMA offers benchmarking and space utilization metrics that help facility managers
align space usage with organizational needs.
Comparison with Other Options:
Industry-specific standards(A): Varies by sector and does not provide a universally recognized
standard for space allocation.
Open Standards Consortium for Real Estate Standard (B): Primarily focused on real estate data
management rather than floor area assignment.
Accessibility standard (C): Primarily related to ADA compliance and does not specify space allocation
for occupants.
