Product Details
To the maximum extent practicable, federal agencies are required to buy sustainable products, which are products that meet the purchasing program(s) listed below.
If there is more than one program listed below, agencies are directed to prioritize multi-attribute products, which meet statutory purchasing program requirements (
) and one or more required Environmental Protection Agency purchasing programs.

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.
GSA's Green Proving Ground evaluated an LED replacement lamp that uses the same four-pin socket and electronic ballast as an incumbent CFL. Results showed energy savings between 40-50%, matching light levels and quality and payback under 3 years. GPG recommends deploying LED downlight lighting in place of CFLs broadly where advanced lighting controls are not desired or useful. GPG's report provides a table of LED replacement options for CFL downlights.
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. 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.
To calculate life cycle cost savings, explore these tools:
- On its Purchasing & Procurement page, Energy Star offers an MS-Excel-based calculator to estimate how much money and energy you can save purchasing ENERGY STAR light bulbs.
- For life cycling costing on specific brand-name products, visit SFTool Product Search
by clicking the green box at the top of this page. Once you have created an account, add a product to a project and open the project. The tool displays energy cost savings, adjusting for local utility rates, operating conditions, and the purchase price. - NREL’s Levelized Cost of Energy Calculator can help estimate the cost of electricity as an input for your lifecycle cost calculations, accounting for both cost escalation and discount rates.
