Building America Team: Newport Partners

Partner: Broan-NuTone

Newport Partners have partnered with Broan-NuTone, the nation’s leading developer and supplier of domestic range hoods, to develop, test, and demonstrate a prototype Smart Range Hood. The smart range hood will far exceed current state-of-the-art and will offer a cost-competitive, affordable, auto-responsive, consumer-friendly, quiet, effective, efficient, ASHRAE-62.2-compliant local exhaust, and whole dwelling unit ventilation solution. The project will involve development of smart controls, an intelligent user interface, and multiple iterations of prototypes; lab testing for capture efficiency, sones, and flow; and field demonstrations.

A prototype smart range hood will far exceed current state-of-the-art and will offer a cost-competitive, affordable, auto-responsive, consumer-friendly, quiet, effective, efficient, ASHRAE-62.2-compliant whole dwelling unit ventilation solution.

Completed work:

  • Selected final sensors
  • Developed Gen 2 prototype
  • Over 350 cooking tests
  • Dozens of control algorithm revisions
  • Tested filters and lenses
  • Completed lab test plan.

Progress toward goals:

  • Efficacy goal: 1.5 x ENERGY STAR® = 4.2 cfm/W. Achieved 4.5–4.7 cfm/W working speed with various configurations.
  • Sound goal: less than or equal to 1 sone, at greater than or equal to 150 cfm. Achieved 0.3-0.6 sones at 150–160 cfm at working speed with various configurations.
  • Capture efficiency goal: greater than or equal to 90%. Achieved 90% at 250 cfm, and 98% at 400 cfm.

Next steps:

  • 2019 will be the final year of this project
    • Complete field test plan and Institutional Review Board approval for human subject research
    • Q1: lab tests with Lawrence Berkeley National Laboratory
    • Q2 analyze test results
    • Q2-Q3: conduct field tests
    • Q3: final report.
