During this step, the owner can reduce costs by employing preferred vendor contracts with advantageous pricing and pre-determined levels of quality.
Step two is to commission the building. Retrocommissioning a building is a cost-effective way to diagnose potential issues and determine how to squeeze more efficiency out of the building’s existing systems. According to Lawrence Berkeley National Laboratory, retrocommissioning “can often resolve problems that occurred during design or construction, or address problems that have developed throughout the building's life. In all, retrocommissioning improves a building's operations and maintenance (O&M) procedures to enhance overall building performance.” Consider investing in the services of a professional commissioning agent already working in similar buildings, who should be able to make both short- and longer-term recommendations. Once the existing equipment is operating at its peak efficiency, the owner can use that performance as a baseline to help evaluate the ROI on equipment replacement.
