Environmental Division

ECS's Environmental Division has researched the myriad amount of technology and products that have been introduced or become relevant due to COVID-19, in an effort to provide the most balanced and complete approach to reintegration.



In 2018 Energy Control Service restructured our departments to meet the demands of the “smart era.” The company has fully embraced the integration of systems and energy management and curtailment.

The Optimus Integration and Service division operates as a certified BACnet Integrator promoting fully open interconnected automation systems while also extending the maximum life of a building’s existing automation system and utilizing all systems to provide the highest level of conservation and sustainability.

While ECS continues to work on “plan and spec” work, which ultimately tends to be cost-driven and not ecologically friendly, we prefer to conduct design and build projects. Our Special Projects department is specifically designed to meet the growing needs of our 45 (and growing) service clients.


Ultimately, a BMS and HVAC infrastructure need constant updating and we have a department dedicated to providing cost-saving analysis. The special projects department seeks to understand the needs of our
non-Optimus service clients and help them reduce energy consumption and waste.
