Making the case for ongoing commissioning

Ongoing commissioning (OCx) has become an industry buzzword in recent years. Typically, OCx applies to new, high-performance buildings, in which a building automation system (BAS) collects and analyzes performance data to help fine-tune the building’s operation. However, such high-performance buildings make up a very small portion of the current building stock in the U.S.

In this course, we’ll demonstrate how many existing buildings can greatly benefit from a simpler form of OCx. Despite the limitations of available data from such buildings, we can perform less sophisticated, but arguably equally beneficial processes to improve building performance. Just as no two buildings are alike—a common refrain in building operations—no two applications of ongoing commissioning should be alike, either. This presentation will detail case studies of buildings that have taken advantage of OCx services. We will cover the processes used, overall best practices, and the benefits of applying these concepts to a variety of buildings.

As a result of this webinar you will be able to:

  1. Define ongoing commissioning
  2. Explain common aspects of an ongoing commissioning process in older, less sophisticated buildings
  3. Discuss the best practices for ongoing commissioning in older, less sophisticated buildings
  4. List the benefits ongoing commissioning provides
