EMCOR Services Integrated Solutions’ expert building-automation and control technicians provide facility-automation systems that help clients manage their facilities more efficiently, responsively, and profitably.

Since 1969, ESIS has been delivering knowledgeable BAS and building-control systems installation, integration, and other services to a wide array of clients across Wisconsin and Northern Illinois.

A single-source provider

Today, ESIS is one of the region’s premier, single-source providers of leading-edge control systems, as well as many of the most widely used open-systems protocols, including IP, BACnet, LON, Modbus, and others.

These protocols enable best-of-breed components from various manufacturers to communicate efficiently with each other and with client’s existing IT, security access, video, and other systems.

Furthermore, rather than locking clients into a single brand, open-systems protocols let clients select from a wide variety of manufacturers’ systems and devices.

Helping clients bridge the controls gap

ESIS building-automation and control-systems integration specialists can help clients bridge the gap between specific control needs their facility’s other systems.

By integrating building systems, clients often receive flexible and efficient interoperability. When clients want to expand, respond to new business opportunities, or take advantage of new leading-edge technologies, ESIS can help do it quickly, efficiently, and economically.

ESIS also self-performs virtually all project activities. In-house mechanical-engineering experts help design clients’ BAS and building-control systems, program its functions, and perform complete installation and integration services—all without subcontracting any part of the work.

In addition to single-source accountability, clients receive building-automation systems (BAS) tailored to their specific comfort, energy, and budget requirements.
