Building Automation and Controls

Expertise to make your facility smart, healthy and energy efficient

Facilities Management

Seamless integration of hardware, software and analytics for a highly profitable facility asset.

Our skilled, experienced professionals are knowledgeable of the latest building automation solutions across multiple manufacturer’s platforms.

Seven Benefits of a Reliable and Efficient Building Management System

  • Reduction of operating cost through energy optimization across sub-systems
  • Reduction of operating cost through minimizing maintenance costs
  • Reduced overhead cost through increased staff productivity
  • Real time analytics for energy conservation, equipment longevity and lower maintenance costs
  • Analytics driven preemptive equipment alerts for zero downtime
  • Automated continuous commissioning
  • Extended equipment lifetime for maximum ROI

Energy Management

Your business will thrive with our energy management expertise and knowledge of the Washington Energy Code.

We can help you meet the Washington Clean Building Performance Standard.


Financial Impact of Building Automation Systems

  • Installing currently developed and properly tuned controls can reduce energy consumption.
  • Commercial buildings ~29%
  • Secondary schools ~49%
  • Standalone retail stores and auto dealerships ~41%

Other measures that provide greatest energy-saving potential nationwide are:

  • Adjusting setpoints (e.g., lowering daytime temperature for heating, increasing for cooling, and lowering
  • nighttime heating) (~8% reduction)
  • Reducing minimum air flow rates through variable-air volume boxes (~7% reduction)
  • Limiting heating and cooling to when the building is most likely occupied (~6% reduction)
  • Sequence of operation audit for most plants 10 years or older (~10-50% or more reduction)

Predictive Analytics

Connectivity solutions designed to monitor any mechanical equipment regardless of manufacturer.

Pro Mechanical Services can provide detailed building analysis to protect equipment, lower energy costs, produce preemptive fault detection and maintain optimal environmental conditions.

Common Findings

  • Low refrigerant charge
  • Reduction in the heating/cooling system capacity
  • Failed components
  • Excessive energy use
  • Inability to maintain comfort and air quality
  • Dirty air filters
  • Degraded compressor efficiency

Long Term Benefits

  • Improved productivity of maintenance staff
  • Reduced trouble calls
  • Improved occupancy comfort
  • Healthy building environment maintained
  • Equipment life extended
  • Reduction in unexpected failures
  • Utilization of real-time data
  • Equipment operations proactively maintained
  • Easier determination of persistent maintenance issues

Integration Services

To the wise investor, modern Building Management Systems are all about integration. Multi-platform system integration is substantially more cost effective than a complete replacement of a DDC system. In fact, many platform “software upgrades” cost more than a complete system integration.

It does however require a highly sophisticated team of competent people with experience to bring multiple front ends into one simple yet powerful frontend package.

Pro Mechanical has assembled a dedicated group of muti-platform integrators to serve a growing need for owners looking for solutions that unlock them from one or more expensive vendors.

Pro Mechanical Services provides hands-on integration management, services, training and support. Integration is one of the messiest and most complex technological services related to building automation, but Pro Mechanical specializes in this field.

The variety of third-party, multi-platform systems in use and the sheer complexity of integration itself, makes the whole process time consuming and difficult but Pro Mechanical as streamlined the process.

We proudly offer best-in-class integration services based on industry expertise and a comprehensive understanding of all major third-party systems.

We can help integrate as many or as few systems as required to meet your business goals. Let Pro Mechanical solve the expensive headache of a multi-platform system for your facility quickly and economically.
