Existing building commissioning - investigation and analysis

Intent

Through a systematic process, to develop an understanding of the operation of the building’s major energy-using systems, options for optimizing energy performance and a plan to achieve energy savings.

Requirements

Option 1. Commissioning Process

• Develop a retrocommissioning, recommissioning or ongoing commissioning plan for the building’s major energy-using systems.
• Conduct the investigation and analysis phase.
• Document the breakdown of energy use in the building.
• List the operating problems that affect occupants’ comfort and energy use, and develop potential operational changes that will solve them.
• List the identified capital improvements that will provide cost-effective energy savings and document the cost-benefit analysis associated with each.

OR

Option 2. ASHRAE Level II Energy Audit

• Conduct an energy audit that meets the requirements of American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), Level II, Energy Survey and Analysis.
• Document the breakdown of energy use in the building.
• Perform a savings and cost analysis of all practical measures that meet the owner’s constraints and economic criteria, along with a discussion of any effect on operations and maintenance procedures.
• List the identified capital improvements that will provide cost-effective energy savings and document the cost-benefit analysis associated with each.
