The Challenge

Hebat Badiee has contributed to and performed several experiences in energy performance contracts when ESCO companies offer energy conservation services.

The City of Livonia hired Hebat's engineering company to perform the energy study and Investment-grade audit for seventeen of the City's own buildings, and assisted them in hiring the ESCO company to perform an energy performance contract. Hebat and his team of engineers designed the projects and provided the services required as an expert to the completion.
