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.

For most applications, Energy Star-qualified cordless telephones have the lowest life-cycle cost. An efficient product is cost effective when the energy costs saved over the life of the product exceed the additional upfront cost (if any) of the more efficient model. Energy Star considers both upfront costs and lifetime energy cost savings when setting required efficiency levels. Federal purchasers can assume that Energy Star-qualified products are life-cycle cost effective.

Guiding Principles
Contributes to meeting The Guiding Principles for High Performance and Sustainable Buildings
Additional Guidance

Federal buyers must ensure that cordless phones meet both Energy Star and FEMP Low Standby Power requirements. The Energy Star version 3.0 specification has an expanded scope including VoIP telephones and corded analog telephones, The Version 3.0 specification establishes new Partial On Mode (formerly Standby) power consumption requirements for all products. It also encourages the adoption of energy efficiency technologies, including Energy Efficient Ethernet to save power in periods of low data throughput and External Proxy Capability to enable end point devices such as computers to maintain network connectivity while in low power modes.
