Small Building Re-tuning Resources

Researchers at the Pacific Northwest National Laboratory (PNNL) have developed a number of useful resources to help re-tune small (<100,000 sf) commercial buildings without building automation systems (BASs):

Small Building Re-tuning Classroom Training Material

The U.S. Department of Energy's PNNL has developed a building re-tuning process to detect energy savings opportunities and implement improvements in commercial buildings. This training is focused on small commercial buildings, to help identify energy savings opportunities, thus making the building more efficient and reduce operating costs. PNNL has developed this train-the-trainer instructor manual, to help qualify more re-tuning course trainers.

Purpose of the Small Building Re-tuning Training Course

The purpose of this course is to help building operations staff to learn how to operate buildings more efficiently, reduce operating cost and provide energy savings. The knowledge and skills learned through the training will be highly valued by organizations and companies seeking to improve the performance of their buildings.

Intended Audience for the Small Building Re-tuning Course

The intended audience for the building re-tuning training includes:

  • onsite employees responsible for day-to-day building operations,
  • offsite contractors (retro-commissioning agents or control vendors) hired to improve a building's energy efficiency, and
  • people interested in entering this field, including college students and military veterans.

The focus is on small (<100,000 sf) commercial buildings that do not have BASs. These buildings have packaged units for heating and cooling with simple air distribution, and are controlled by a zone thermostat. Many of the recommendations for small building re-tuning are prescriptive. However, for buildings that do have a BAS, some of the concepts and techniques presented can still be applied.
