Continuous Commissioning®

Continuous Commissioning®, or CC® is an ongoing process to resolve operating problems, improve comfort, and optimize energy use for existing commercial and institutional buildings and central plant facilities. CC® incorporates and extends existing building commissioning practices. Find out how the CC® process can help you with your sustainability, energy management, and carbon footprint reduction objectives.

CC® Facts

  • Implemented in over 900 buildings
  • Provides an average project simple payback of under 2 years
  • Used in climates around the globe
  • Has produced over $390 million in savings as of December 2017

The Process

The Energy Systems Laboratory has developed the Continuous Commissioning® process to improve comfort and performance using cost effective measures. CC® incorporates the best of retro-commissioning techniques into a process that has achieved superior performance in over 300 buildings around the globe. The objective of CC® is to produce a rapid payback while providing sustained improvement to building performance according to the facility’s actual use. The process:
  • results in improved occupant comfort and satisfaction
  • normally uses existing equipment rather than costly retrofits
  • achieves higher system efficiency over traditional methods

Investigation and Modeling

Opportunity Assessor

Using measured energy consumption and some basic questions about the building, Opportunity Assessor identifies the potential savings opportunity for it. It is useful at the early stage of identifying—in a systematic way—buildings which are good candidates for the CC® process.


This tool is used in the CC® process during the detailed assessment. From this assessment, engineers create an hourly-simulation model, and calibrate it to the measured energy consumption. Then the model can be used to predict savings by applying various energy efficiency measures.

Implementation/Data Analysis/Visualization


This tool is used in the CC® process to acquire, store, time-align, analyze, and visualize trend data obtained from the building automation system in a scalable manner. With more and more data flowing from buildings, it makes sense to extract useful information without getting flooded with data. Analysis includes fault detection and issue management.

Ongoing Commissioning


Honest and transparent Measurement & Verification (M&V) is important in the CC® process. Based on an agreed-upon selection algorithm, Validator automatically creates inverse models, stores energy consumption data, and estimates realized savings from the CC® process. Read a recent academic paper from our team that describes the approach.


The Energy Systems Laboratory not only implements Continuous Commissioning®, but licenses its CC® technology and practices to firms. These firms have access to the tools, research and expertise that make the CC® process effective. This select group of Engineers and Building Professionals have the necessary skills and training to quickly identify the best improvement opportunities—those that can be implemented with the least cost while producing the greatest impact.

Business Development Representatives

TEES has also signed business development agreements with the Energy Commissioning Group and MEH Consultants to present and market the benefits of CC® services for the TEES Energy Systems Laboratory.
