The tool aims at minimizing the life-cycle cost
of chilled-water plant by finding optimally both condenser water- and chilled-water-side design variables such as chilled water and condenser piping sizes, chilled- and condenser water temperature differences [DELTA]T, and chilled-water supply temperature.
A source-selection team that wishes to use LCC or the most probable life-cycle cost
(MPLCC) for cost contracts in its source-selection criteria will run into a great deal of resistance.
In conjunction with the LCCC update, AGA released "Costs Less, Lasts Longer," which discusses the parameters of initial and life-cycle cost
analyses, and provides four case studies.
comparisons were made for one-lamp and three-lamp luminaires for TFLs and TLEDs, and two-lamp luminaires for TFLs and all three LED retrofit options.
General Services Administration (GSA) to consider life-cycle costs
during the design of buildings for structures whose estimated construction costs top $1 million, and where the federal government is paying more than half of the construction expenses.
GAO's objectives were to (1) develop an independent estimate of the full life-cycle costs
to homeport a nuclear aircraft carrier at Mayport and (2) determine to what extent the Navy's estimate meets the characteristics of a high-quality cost estimate.
These trends suggest the existence of a particular value of the maintenance period for which the expected life-cycle cost
becomes a minimum value.
We pursued and were a leader in developing both molten carbonate and phosphoric acid fuel cell technologies until the late 1980s, at which point we made a strategic decision to commercialize only phosphoric acid due to its superior durability, reliability, and lower life-cycle cost
"The structural integrity of the design along with the plant's operating features and benefits are what translates into supporting the lowest possible life-cycle cost
," he says.
Many agencies are investigating economic tools such as life-cycle cost
analysis (LCCA) that will help them choose the most cost-effective alternatives and communicate the value of those choices to the public.
The system must have a low life-cycle cost
; must be technically robust, reliable, maintainable, socially acceptable, and affordable; must be manufactured and serviced in a developing country; and must not degrade other water quality characteristics.
