What is the RCx Process?

TMCx Solutions' Methodology for Providing Cost Benefit Analyses

The Owner of the commercial building and the facility staff are key to our ability to provide the best suite of Facility Improvement Measures (FIM's), which in turn increase your energy efficiency and therefore, your bottom line. Your knowledge of the building gives us the critical information we need to understand the purpose, goals, and objectives for the building and how these parameters have changed over the life of the building. These parameters guide us in integrating our factual information with the current requirements. This approach ensures our list of facility improvement measures will meet your goals and expectations.

TMCx Solutions' Approach to Retro Commissioning and Energy Analysis

Building size does not factor into our approach. We manage each building in the same way when conducting retro-commissioning projects. You can expect TMCx to systematically analyze the functionality of the designated commercial building systems; make recommendations for performance improvements that meet their unique operational needs and the requirements of current building usage; identify opportunities for reducing energy and saving money; and provide monthly progress reports that meet the schedule and milestones for each commercial building.

The TMCx Approach to RCx demands collaborative involvement in order to increase the success of our identifying, analyzing, and problem-solving phases. Our role is to clearly:

By doing this in a collaborative manner, we promote more efficient and effective energy solutions. This means we want input from all sources who will give us insight into the building's energy consumption patterns. We embrace a team approach that involves as many members as possible throughout the process, including current occupants and facility staff. TMCx ensures the Owner's Facility Requirements and the RCx timelines are met.

TMCx Solutions' Goals for Retro-Commissioning

With any Retro-commissioning project, TMCx Solutions has the following goals:

  1. Investigate and analyze the building to identify areas where electrical demand and natural gas consumption can be reduced
  2. Provide cost-effective operational and maintenance recommendations to optimize efficiency of existing equipment, while improving occupant comfort and saving money
  3. Provide to the Owner, upon completion of the process, a written report that follows ASHRAE procedures for Commercial Building Energy Audits
  4. Test and verify the success of the system performance after repairs, adjustments, and chosen energy measures have been implemented
  5. Give tools and training to create continuous improvement of the system's performance.

TMCx Solutions' Phases for Delivering Services and Meeting Goals

To meet these goals, our Retro-Commissioning approach is provided in the following 5 phases:

retro_planning

Planning Phase – includes the development of the scope of work, identifying available resources (information, tools, and personnel), defining the facility operating requirements, and documenting the owner's expectations of the facility operation.

retro_investigation

Investigation Phase – includes the development of an RCx plan, review of existing documentation, interviewing key personnel and/or tenants, inspection and functional testing of identified systems, and identification of Facility Improvement Measures (FIM's).

retro_analysis

Analysis Phase – includes detailed analysis of data acquired during the investigation phase, benchmarking the facility's energy use, performing energy savings calculations for each identified FIM as well as associated costs for payback. Prioritized recommendations are provided with the corresponding anticipated energy savings.

retro_implementation

Implementation Phase – includes close collaboration with the Owner to review and select the energy-saving measures that best fit the Owner's criteria. These are then implemented by the appropriate contractor(s), procured by the Owner.

retro_documentation

Documentation Phase – includes verification of the FIM's through formal systems testing and monitoring of building operational data. A final report thoroughly documenting the entire Retro-commissioning process is provided. This includes:

  • Testing and verifying your system's performance upon completion of any repairs, adjustments, or equipment replacement.
  • Assisting with the training and mentoring of O & M staff on current operating sequences and troubleshooting for the optimal operation of your systems.
