Ongoing Commissioning

Existing buildings can target potential saving areas by retrocommissioning. While a retrocommissioning process is useful every few years, buildings can optimize their energy savings by implementing ongoing commissioning. Ongoing commissioning happens at frequent intervals, such as every month or several times a year. Instead of waiting until the next retrocommissioning year, owners can immediately act upon problem areas.

To be successful in this process, building operators must have access to a steady stream of incoming data about their building. The goal is to be able to automatically or easily compile the data into a document for easy analysis.

For example, this data may come from:

  • Building Automation Systems
  • metered equipment
  • utility bills
  • regular interviews with building tenants
  • regular quantitative inspections of building systems such as heating, cooling, plumbing, electrical, and other mechanical and utility systems.

Ongoing commissioning requires trained staff to analyze incoming information and make minor changes to systems when necessary. The goal of ongoing commissioning is to continue to meet the building owner's project requirements. This process is helpful when conducted in reference to a financial goal. It is important for a building owner to routinely confirm if the projected cost savings from retrofits are being achieved. Therefore, regular communication between owners and operators is necessary. Workforce training is also necessary for successful ongoing commissioning.
