REAL-TIME ESTIMATION OF THE NUMBER OF ELECTRONIC THERMOSTATS

Estimate the number of thermostats in operation from a single power measurement at electric panel

Challenge in residence heating loads monitoring

  • In cold-climate regions, heating is an important part of the overall residential electricity consumption.
  • Estimating the energy needed to heat a residential building is crucial for thermal performance evaluation.
  • Most homes in North America include one or several electric baseboards per room, each room having its own thermostat.
  • Electronic thermostats in a residence often have identical electronic signatures; a system is therefore needed to differentiate them.

Estimation of the number of electronic thermostats

  • This technology allows the non-intrusive real-time estimation of the number of electronic thermostats in operation in a residence, each thermostat controlling at least one thermal load.
  • Present system and method rely on a combination of event analysis and frequency domain analysis.
  • Proof of concept tested experimentally.
  • Technology developed by Profs. Kodjo Agbossou, Sousso Kelouwani and their team at Université du Québec à Trois-Rivières.

Competitive advantages 

  • Estimation of the number of thermostats in operation from a single power measurement at electric panel.
  • Non-Intrusive Load Monitoring without any need for sensors.
  • Very useful in North America where houses are often heated with electric baseboards.
  • Thermal performance evaluation and heating abnormalities detection.
  • Can be used to detect the number of any kind of appliances functioning on 2-stage ON-OFF states.

Business opportunity

  • US patent application 16,441,104
  • Technology available for licensing
  • Co-development for specific platform implementation
