For new system commissioning, EES will install and remove instrumentation when the system is complete and ready for startup. EES will work with the designer and installation contractor to monitor and provide feedback for a few weeks up to a few months depending on the system needs. EES will certify the system is in good operational order and provide a report and metrics that can be used for future re-commissioning. As an option the facility can install permanent equipment and EES can be retained to ensure that performance does not degrade through regular reporting.
For existing systems, EES will also install and remove instrumentation. After installation, EES conducts an initial characterization period that results in a baseline of energy performance and thermodynamic metrics. Then EES works with the facility personnel or contractors to go through a phased approach to retuning and re-commissioning. After the completion of the phased retuning and recommissioning, EES will supply a written report on the changes and results of the changes. As an option the facility can install permanent equipment and EES can be retained to ensure that performance does not degrade through regular reporting.
For existing systems there are more involved options past the level 1 tuning. The system may be a good candidate for a larger retrofit of controls, compressor, or condenser fan components, heat recovery, circuit re-alignment, or other cost-effective strategy. At that point the changes can be discussed, and utility incentives leveraged if there is a significant opportunity.
EES also provides general performance verification, investigation, warranty claim support, independent M&V, and refrigerant change out support to clients of all types and sizes.
