Re-tuning Benefits

Re-tuning helps enable:

- Cost-effective facility energy savings (up to 25%)

- Significant cost savings

- Improved building occupant comfort

- An in-house O&M capability that benefits organizations for years.

Re-tuning is a systematic process aimed at minimizing building energy consumption by identifying and correcting operational problems that plague buildings at no-cost or low-cost. Re-tuning relies on building automation system data to identify and implement control improvements at no cost other than the time to program the changes.

These low-cost or no-cost operational improvements ultimately improve the buildings' energy efficiency, reduce operating costs, and improve occupant comfort.

An active energy management program utilizes many practices to reduce energy use. Re-tuning is one practice that has been verified to produce energy savings ranging from 5% to 25% in federal sites. Re-tuning is an effective, low-cost and relatively easy method for reducing building energy use primarily accomplished through the building automation system controls.

The primary steps of re-tuning include:

  1. Basic building information collection
  2. Trend-data collection and analysis
  3. Building walk down
  4. Identify and implement re-tuning actions
  5. Report findings and recommended actions and implementations
  6. Analyze savings
  7. Continued use of re-tuning in operation and maintenance.
