Life-cycle costing: counting all costs from acquisition through end of life

One-line orientation

Life-cycle cost analysis compares monetary costs over time. An option with a higher first cost may cost less after operation, maintenance, replacement, and end-of-life costs are included.

Key points

• Life-cycle costing accounts for ALL costs over a building’s life, not just what it costs to build.
• Three main monetary cost categories (with when each is incurred):
  1. Initial / first costs — acquisition (land + raw materials) + design fees + construction (labor, systems installation). Incurred one-time, at project outset.
  2. Operational costs — energy (HVAC, lighting, equipment), water, routine maintenance and repair. Recurring throughout the building’s life and potentially a substantial share of total cost.
  3. End-of-life costs — demolition and disposal, offset by any salvage value (residual value of materials/components that can be resold or reused). Incurred at end of useful life.
• Environmental and social impacts belong in life-cycle assessment or another broader evaluation unless they are converted to monetary values for the cost analysis.
• Compare costs on the same time basis. Future operation, replacement, and residual values are discounted to a common date so money spent years from now can be compared with today’s cost.

Life-cycle cost: the option cheapest to build is often costliest to own

Each bar stacks one option’s lifetime costs; salvage is a credit carved off the top.

Confusions / comparison

Criterion	Option A — cheaper to build	Option B — efficient but pricier upfront
First cost (one-time)	Low — wins the construction bid	High — loses the construction bid
Operational cost (recurring)	High — more energy use, more frequent maintenance/repair	Low — efficient systems cut recurring energy and upkeep
Total life-cycle cost	Often higher once recurring costs accumulate over the building’s life	Often lower — upfront premium repaid by operational savings
Better long-run choice?	No — the “obvious” cheap bid is the trap	Yes — lowest total cost of ownership, not lowest first cost
