The Pacific Northwest National Laboratory (PNNL) has developed a building Re-tuning approach to detect energy savings opportunities and implement improvements. The purpose of the building Re-tuning course is to enable you to reduce operating cost and provide energy savings to the building you are responsible for. The knowledge and skills learned here are highly valued in the energy, controls, heating, ventilation, and air conditioning (HVAC), green, and sustainability industries and help make our planet healthier.

The focus is on large (100,000+ square feet) buildings, but the concepts and techniques presented can be applied to any type and size of facility that has a building automation system. This course assumes that learners have a working knowledge of HVAC and other building systems. Throughout this course, you will learn the initial steps involved in re-tuning a building controlled via a building automation system. Be sure to check out the Resources page as well. There, you can download helpful tips sheets, checklists, and access related websites and other valuable resources to help you become a building re-tuning expert.

Learning Objectives

Upon completing this course, you will:

  • Participants will learn what Re-tuning is, why to Re-tune a building and how Re-tuning can help "optimize" facilities and enhance the performance of facilities;
  • Common energy savings opportunities identified by Re-tuning;
  • Learn how to identify selected opportunities for improvement to reduce overall energy consumption;
  • Learn about potential savings when these common problems are corrected.
