    Energy Consulting & Services



MEP Consulting

In addition to the Commissioning, Retro-Commissioning and Energy Auditing, The Commissioning Authority team members actively provide MEP consulting services for a wide range of projects, please let us know if such engineering services are needed and we will put you in touch with our MEP Consulting team members for additional information. Our goal is to keep complete your projects and to minimize continued losses in energy found at your facilities.


Sustainability Consulting

The Commissioning Authority has substantial LEED and sustainable building design experience through participation in numerous LEED projects, and is currently accessible to provide the following services to our clients:

  • Participate in project LEED meetings.
  • Review LEED Score Card and determine normally achievable and other potentially achievable points in response to projects certification goals.
  • Prepare Energy Modeling and related LEED Points documentation.
  • All other MEP related LEED points and certification documentation.
  • Develop and actionable plan to best deliver todays resources into your buildings


Feasibility Studies

Our staff has provided the Energy Division of the California Public Utilities Commission (CPUC) with review and assessment of a broad range of feasibility projects throughout California. These large-scale projects have ranged from Thermal Oxidizers to Central plant upgrades utilizing utility rebates and incentives. Let TRG assess the success of your projects before you start spending and arranging commitments from firms with little knowledge about the entire process and analysis tools required. Again, our goal is to keep your project moving through to completion to minimize continued losses in energy found at your facilities.

Take a look at our “In-depth” Feasibility study Task:

  • Meet with management to discuss the EEMs (system options) that will be re-evaluated by performing an in-depth Feasibility Study.
  • Coordinate with the utility representative to reserve utility funds for the estimated project size.
  • Audit the facility to collect appropriate field data to perform system energy simulations and identify in detail the EEM implementation logistics. (Even after initial data collection has been. performed with a Screening Audit or PEA (Preliminary Energy Audit), additional field data is often required for a feasibility study.)
  • Specifically, collect the following data:
    • Building information: This is collected using architectural, mechanical, and electric drawings, and from a facility walk-through. (Often this is done with a building engineer who is familiar with the facility, the building systems, and system operations.) This includes items such as orientation of the building, how the occupied space is used, the physical dimensions of spaces, construction material, windows, lighting, interior electric loads, and more. This information is used to run a cooling-load simulation model. (In this context, cooling load is defined as the amount of heat that is instantaneously added or removed by the cooling equipment.) This also includes information about present and future building occupancy requirements.
    • Air-handling system information: This data is acquired using the facility’s mechanical drawings that show existing equipment layout and from the air system equipment specifications, control diagrams and system operating parameters, and operating schedules. This data includes measured cubic feet per minute, motor horsepower, minimum and maximum outside-air intake, and more.
    • Central plant equipment information and operating requirements: This includes chiller operations logs, running trend data from the building automation systems.
  • Review and analyze earlier electric bills.
  • Perform system energy simulation of the baseline system and for the system options using engineering spreadsheets or computer-generated building model.
  • Identify the facility’s cooling load requirements (kW profile), peak and monthly
    representative-day” tonnage profiles (weekdays, Saturdays and Sundays).
  • Model the current and future central plant operations to identify the annual electric consumption (kWh usage profile) for the current central plant operations and for all of the EEM options being considered.
  • Using manufacturers’ cost sheets and typical labor costs, determine the estimated implementation costs for the EEM options.
  • Perform life-cycle cost analysis of the current plant and of the future options in accordance with utility interest rates and measure useful life.
  • Develop a draft report for management’s review and approval.
  • Develop the final report and present to management and utility for rebate reservation.
