The Pacific Northwest National Laboratory (PNNL) has developed a Building Re-tuning approach to detect energy savings opportunities and implement improvements. In addition to onsite training, PNNL is now offering a free interactive e-learning course to anyone interested in improving a building's energy performance and the comfort of the building's occupants.
Course Description
The purpose of this 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, HVAC, green, and sustainability industries and help make our planet healthier.
Throughout this course, you will learn the initial steps involved in re-tuning a building controlled via a building automation system (BAS). Interactive exercises are included to provide you "hands-on" practice of the re-tuning process within a virtual building. You will practice identifying opportunities for energy improvement and then deciding how to re-tune for more efficiency.
Target Audience
The intended audience for this course is 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 college students interested in entering this field. The focus is on large (100,000 sq. ft.) commercial buildings (office buildings, malls, and schools), but the concepts and techniques presented can be applied to any type and size of facility that has a BAS.
Course Duration
This training takes 5 to 6 hours to complete. It does not have to be done in one sitting; in fact, it is recommended that you spread your training sessions out over several days.
Continuing Education Units
The Building Operator Certification (BOC) Program offers continuing education units (CEUs) for those who complete the Building Re-tuning Training. At the end of this course, simply print the acknowledgment of completion page and contact BOC to receive credit. For more information, visit the BOC Certification Maintenance page.
