Client Testimonials

"ECS is an incredibly hands-on and highly attentive company. I call Mike Bronzo and he responds in five minutes or less." - Jeff Moran 



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.

The Gem in the ECS crown is our system at the Park Avenue Plaza. ECS debuted its Optimus services at PAP in 2015 and in concert with the building Engineers and Fisher Brothers management have created one of the most intelligent, dynamic, and self-learning BMS systems in NYC. P.A.P uses half the energy of other buildings with the same 1.2 million square feet layout. The building was a multi-year upgrade where transitioned non-bacnet Johnson panels to bacnet reliable panels. ECS created an advanced dashboard which seamlessly integrates the Trane Chiller program, IES smart metering, and Lutron into one singular Building Management interface. The building was one of the first to receive automatic equipment reporting and predictive analysis. The improvements at PAP are too long to list.
