Mechanical and Energy Engineering Consultants

Our Company

Our core value is continuous improvement in communications, technical product, and project management. Regardless of our project role we seek to compliment the capabilities of our project partners in facility permitting, design, construction, and operations.


Enterprise Planning, Project Management, and Cx Planning

Energy System’s commissioning competency has grown from over a decade of central plant and laboratory design and start-up experience at technology, gaming, governmental, military, and university facilities. Our staff include Certified Commissioning Authorities (CxAs) with the communication skills, industry experience, and technical expertise to design and execute commissioning and quality assurance processes under contract with building facility owners, contractors, or as the Engineer of Record.

Energy and Engineering Analysis

Science and technology are our passions that complement our roles as design professionals. Our staff have earned advanced degrees in science and engineering that support capabilities including:

  • Energy Analysis and Energy Retrofit Studies
    • CHP, Renewable Energy, and Energy Storage
    • District Energy including Chilled Water, Hot Water, and Steam
    • Distribution Systems
    • Laboratory Ventilation & Air Treatment
    • Central Plant Systems Analysis – Electric & Steam Driven
      Pumping and Water Chillers, Absorption Refrigeration, Steam
      and Hot Water Boilers
  • ASME B31.1 code pipe stress analysis
  • Greenhouse Gas and Carbon Footprint Analysis
  • Air Quality Emissions, Permitting, and Control Systems

Mechanical and Plumbing Design and Permitting

Energy System’s principals are currently licensed in CA, NC, OH, & FL. Our core competencies include commercial, institutional, and industrial mechanical, electrical, and plumbing design with significant experience in preparation of construction documentation for both facility retrofit and new construction. Our principals’ experience includes both leading and partnering on multi-disciplinary design teams supporting facility design, constriction, start-up, commissioning, and operations support.
