An interactive tool based on an extensive automotive materials and components database that guides automotive product designers in evaluating sustainability criteria and tradeoffs between commercially viable material alternatives for automobile components.
Developed by the Rochester Institute of Technology under an NCMS award, this tool helps users identify candidate parts for remanufacturing based on sustainability and cost justification criteria and determine if a product concept should consider key design criteria and best practices that facilitate remanufacturing.

NCMS-developed these Excel-based Cradle-to-Gate (C2G) and Gate-to-Gate (G2G) tools for manufacturers to estimate environmental and energy impacts of furniture materials and chemical substances included in the ANSI/Business and Institutional Furniture Manufacturers’ Association (BIFMA) e-3 Furniture Sustainability Standard.
An interactive Sustainable LED Product Design Guide software tool was developed and deployed that can aid architectural and lighting designers and engineers in making material and design decisions that consider important environmental impacts across all phases of the life of an LED lighting product.
Acknowledgement: This material is based upon work supported by the Department of Energy (National Nuclear Security Administration) under Award Number DE-FG26-08NT02239.
Rationale: Solid-state lighting, using light-emitting diodes (LEDs), has high energy saving potential over conventional incandescent and fluorescent lamps currently in use. However, although there are great energy savings in the use-phase of the lamps, the remainder of the product lifecycle is not so cut-and-dried. LED products rely on on-board or sometimes off-board power supplies and other electronic circuits. Aluminum heat sinks may be required for heat management to maintain long lifetimes. Adhesives or fasteners are necessary to hold all the constituent components together. All of this added complexity has an environmental footprint, especially when considered against the relative simplicity of fluorescent tubes and screw-in incandescent bulbs. Only by evaluating the entire product lifecycle, from raw material extraction to manufacturing to use through end-of-life, can the overall ecological impacts of the lamps be determined.
The Project: National Center for Manufacturing Sciences (NCMS) and Ilumisys partnered on a three-year project awarded by the United States (U.S.) Department of Energy (DOE), to quantify the impacts of LED lamps, incandescent lamps and fluorescent benchmark lamps over a product lifecycle based on operational and durability testing of a variety of lighting products including power consumption, light output, and useful life of a lamp in order to allow a more realistic comparison of lamp designs.. An interactive Sustainable LED Product Design Guide software tool was developed and released in September 2011.
Deliverables: The Guide is available at www.ncms.org as an online tool. It has three novel features for efficiently evaluating LED lighting design features in ‘what-if’ scenarios:
- Bill-of-Materials (BOM) Builder – Designers may import process data for each component and supply functional data for the product, including power, consumption, lumen output and expected useful life.
- Environmental Impact Review – Designs are comparable across lifecycle phases, subsystems, and environmental impact category, and can be normalized to a user-defined functional unit.
- Drill-down Review – These provide an in-depth look at individual lamp designs with the ability to review across subsystem or lifecycle phase.
Benefits: The Guide can aid architectural and lighting product designers and engineers in making design decisions that consider three important environmental impacts (greenhouse gas emissions, energy use and mercury emission) across all phases of the life of an LED lighting product.
