Project: Northeast Residential Lighting Hours-of-Use Study

NMR had led a coordinated effort to measure hours of use (HOU) of light bulbs in residences in four Northeastern states. The study involved logging over 4,000 light bulbs in over 800 homes in the four participating states. The primary objective of the study was to estimate HOU not by bulb type but by room type, under the assumption that people are likely to use their lights in a given room the same way regardless of the type of bulbs in the room. Saturation estimates from other studies conducted in the future could then be applied to these room-by-room HOU estimates to develop overall estimates for LEDs, standard CFLs, or specialty bulbs. As part of this study, NMR developed load shapes for lighting and provided project sponsors with a tool that allows them to view load shapes by home type, income, bulb type, and time period.

Project: Evaluation of Consumers Energy’s Residential Lighting Program

NMR (under a subcontract to Cadmus Group) manages the evaluation of Consumer Energy’s ENERGY STAR lighting program. The work has included interviews with staff and participating manufacturers and retailers, development of a logic model, a review of other lighting programs, a delphi panel to estimate Net-to-Gross, as well as telephone surveys, focus groups, and onsite visits with residential customers.

Project: Evaluation of the Residential Lighting Point-of-Sale and Sales Performance Programs

NMR (as a subcontractor to Research Into Action) led the evaluation NYSERDA’s Residential Lighting Point-of-Sale Program. This market effects, market assessment, process and impact evaluation included conducting in-depth interviews with lighting manufacturers and retailers and combining the data with secondary sales data, and saturation and hours-of-use data collected through a coordinated multi-state study, to assess market progress, program attribution, and net-to-gross.

Project: Residential Lighting Program Evaluation

NMR has been evaluating residential lighting programs in Massachusetts since 2002. They currently are leading a comprehensive evaluation effort that assesses the impacts of recent changes in the market on residential lighting. For example, the team is exploring how recent increases in lighting efficiency standards have affected residential bulb purchase and use behavior. The effort also examines trends in LED availability, pricing, and adoption. NMR is also evaluating the recent Market Lift Program in Massachusetts, including assessing the viability of this design for LEDs and non-lighting products.
