Life Cycle Cost Savings

Life Cycle Costing (LCC) aims to quantify the financial impact of a product over its entire life cycle to assist consumers in making decisions that will save them money over the long term.

An efficient product is cost effective when the utility costs saved over the life of the product exceed the additional upfront cost (if any) of the more efficient model. Federal purchasers may assume that Energy Star-qualified products and products meeting FEMP-designated efficiency requirements are life-cycle cost effective. However, users wishing to determine cost effectiveness for their application may do so using the cost effectiveness examples on FEMP's product web pagesopens in new window.

GSA's Green Proving Groundopens in new window found that variable-speed magnetic levitaton chillers (maglev) are 35% more efficient than FEMP-designated high-efficiency rotary screw chillers. They can acnieve a 42% energy savings and have a payback of 5 years or less, after normalizing for payment structure and utility costs.
