This project is based primarily on the ongoing PIER project in kitchen lighting for new construction. The main research findings from that prior work as they relate to this project indicate:

• There are a significant number of incandescent downlights installed during renovations.
• Kitchen renovation is the most common remodel project.
• Installation and related costs are a significant opportunity for a system approach to reduce overall cost.
• The majority of the cost in kitchen lighting is installation labor.
• Many components of experimental designs for new construction are relevant to renovation.

An alternative effort at PNNL is looking at a procurement effort for a component-based approach. That effort seeks to drive cost out of the downlights by procuring large quantities of downlights for residential applications. While there is some merit in this approach, it is felt that the area for development should be in the integration of systems, installation methods and process, not the product component cost.
