  • She develops open-source energy system and GHG emissions modelling tools to support net-zero strategy implementation at the city level. She designed for the City the Toronto a linking tool to bridge the long-term capacity expansion and short-term production cost-model through the disaggregation of key energy data, which ensures seamless communication between those models and increases value for decision-makers.
  • She works on custom data processing tools to evaluate and visualize modeling results for non-technical stakeholders.
  • She supports clients with the creation of training videos to allow both technical and non-technical users to learn to use modelling tools.

Nolwen previously worked for Novea Energies, a specialty firm and leader in the design and manufacture of solar street lighting systems. She took on diverse tasks that allowed her to gain a comprehensive overview of electronics, photometry, energy management and lighting manufacturing.

Nolwen graduated with a Master’s in Industrial, Mechanical and Energetical Engineering from the French engineering school École Nationale Supérieure d’Arts & Métiers ParisTech. She also holds a Master’s degree in Environmental engineering from École de Technologies Supérieure with a research thesis on the inventory of CO2 emissions with high spatial and temporal resolution of road transportation in Montréal.
