The PPESCO Process

Post-project monitoring

A PPESCO project's long time horizons create opportunities for more energy improvements and new projects.

After project installations are complete, the 10 to 15 years of contract performance begin. Given these time horizons, a PPESCO will need to maintain a positive working relationship with the client over a very long period, if for no other reason than to ensure that M&V is regularly carried out and reported.

In addition to monitoring the performance of the initial improvements, future projects that can yield additional savings can be devised. Despite the PPESCO’s objective of installing comprehensive building improvement measures, effective energy improvement never stops. Staff who manage the client relationship after the project work is complete should continuously look with the building owner for additional opportunities to save more energy.

The post-project monitoring phase follows the building commissioning process that introduces building owners, operators, and tenants to their improved facility. Commissioning also involves initial training of client staff on how to inhabit, operate, and maintain the facility.

Post-project monitoring begins the agreed-upon M&V procedures to determine energy savings and system performance. Deeper training of building systems staff or the owner is a part of this phase, as are the operations and maintenance procedures to ensure systems continue running appropriately.

The post-project monitoring is a phase, whereas M&V is a function that pertains both before and after the project is complete. M&V is critical for demonstrating energy savings relative to contractual obligations, and for assuring lending institutions that predicted cash flow from energy savings has materialized.

A long-term relationship allows a PPESCO to understand the institutions it serves. It also trains building occupants, operators, and owners in understanding building energy. This training can result in lasting behavioral change, a major influence on energy use. An ongoing relationship makes it possible for PPESCOs and client building managers to identify additional energy-saving opportunities—and to act to capture them. This is called Continuous Energy Improvement. And finally, an ongoing relationship between a PPESCO and the client creates an easy avenue for introducing and transferring new technology. This kind of transfer assures that the building benefits from emerging technology that advances energy performance and reduces greenhouse gas emissions.
