Building Automation & Control Systems

As heating and air conditioning systems age their control and mechanical systems become less efficient and lead to greater cost for energy, repairs and replacements.  By renovating and upgrading various components of your facility’s mechanical systems, MSES delivers significant energy savings while making your building more comfortable for you, your staff and your customers.

EFFICIENCY… do you need immediately results, lower operating cost, improved customer experience, but fiscal requirements dictate a phased in approach on mechanical capital improvements? MSES Building Automation & Control Systems designs and installs Building Automation Systems (BAS) for customers where gaining automated control and monitoring of their existing mechanical systems lends itself to performance optimization, energy efficiency and operational savings.  We utilize pioneering technology, advance and inventive controls systems, across all manufacturers, to integrate and control any existing mechanical system, including heating, ventilation, air conditioning, power monitoring, and plumbing systems. With its expertise and experience and wide range of products, MSES is able to design control solutions to fit your capital improvement plan, correct your system’s performance gaps and save you as much as 40% on your operating cost.

What Types of Systems Are Controlled?


In generally, building automation begins with control of mechanical, electrical, and plumbing systems:

  • Chillers
  • Boilers
  • Domestic Hot Waters System
  • Air Handling Units
  • Roof-top Units
  • Fan Coil Units
  • Cooling Towers
  • Heat Pump Units
  • Variable Air Volume Boxes
  • Building Pressurization
  • Refrigeration Units
  • Lighting Controls
  • Utility Meters
  • Optimal start /stop
  • Occupancy-based environmental controls
  • Advanced web based & alarm based monitoring


What Does a Building Automation System (BAS) Look Like?

Most controlled automation is behind the scenes as hardware devices mounted to HVAC equipment are hidden under the floor or in the ceiling.  Some personalized control, as an option, is available through thermostat-like devices.  From a central management perspective, the BAS resides as software on an operator workstation, a computer, as a web page.  Controllers manage heating and air conditioning equipment and portions of the network, with sensors providing input data to the controllers.  From a mechanical contractor’s perspective below is a generalized view of a BSA.


Building system controls is a growing industry and you may hear several terms of brand or applications, all if which MSES is expert in the design, installation and management of:


  • BACS/BCS/BMS: Building Automation and Control Systems (BACS), Building HVAC Control System (BCS), and/or Building Management System (BMS)— the same as “Building Automation System”
  • DDC: Direct Digital Control describes the communication method used in modern devices (hardware and software). Collectively, DDC products control various building HVAC systems and form the automation system.
  • EMS: Energy Management System is generally understood to be the same as a “Building Automation System” but with emphasis is on energy metering/monitoring of the HVAC systems.


MSES provides building control solutions that are centralized and interlinked, networks of hardware and software, systems that ensure optimal performance, comfort and safety; we are recognized across the nation as an expert integrator of these solutions and we have one that is right for you.

MSES is Energy. Efficiency. Excellence… and Service.
