COLLABORATIONS

The research activities in axis Energy  are carried out within the IES laboratory, in collaboration with the LEME laboratory at the University of Paris Ouest-Nanterre-La Défense, the LMT Laboratory of ENS Cachan and in the CREIDD laboratory at UTT.. 

EQUIPMENTS

In order to model and simulate thermal machines integrated in the building, axis Energy is using the following software:

  • MATLAB / Simulink / SimPowerSystems: modeling and simulation of complex dynamic systems;
  • LabVIEW: development of acquisition applications, measurement data and control analysis;
  • COMSOL Multiphysics: modeling and optimization of thermal systems (machines, buildings, etc.).
  • BBC + platform (in collaboration with UTT and URCA, GRESPI laboratory): the Energy axe is involved in the sensor equipment (temperature, brightness, hygrometry, CO2) of the new EPF building as a real scale building for the thermal studies of the building and the occupant's comfort, as well as the deployment of a prototype of a sustainable house (RT2020 norm) composed of hot and cold zones to test several atmospheres in hot and cold climates.
