Delta Conso Expert

the energy consumption analysis software

Our design office has developed an ambitious IT development program with the support of the university laboratories of Poitiers. This program has received financial support from FEDER and OSEO. This initiative has led to the creation of the Deltaconso Expert® software.

This comprehensive software brings together in a single tool the energy management of assets for companies and municipalities. From inventories of existing systems to the verification of the measures implemented, Deltaconso Expert® makes it possible to execute an energy and finance improvement plan by assessing and monitoring energy consumption and costs. Based on the energy mapping carried out, our engineers can execute an energy performance improvement plan. This plan is accompanied by funding solutions, and Deltaconso Expert® enables you to monitor changes in consumption in real-time.
