The definition of Resilience, as per a 2013 Presidential Policy Directive, includes the ability to withstand and recover from deliberate attacks, accidents, or naturally occurring threats or incidents. Seen through the prism of facility energy consumption, the ability for a DoD facility to maintain and support mission readiness is critical upon the reliability of accessible electricity, water, natural gas, etc. Commissioning (Cx) and Re- or retro-commissioning (RCx), or the process of ensuring that a new or existing building’s performance continues to meet or exceed its original design and changing facility requirements over time. To ensure that these facility systems maintain reliability and support energy resiliency is the ultimate focus and goal to successful commissioning/retro-commissioning. This presentation will convey the importance and dependence of facility commissioning/retro-commissioning as a critical, if not the most important aspect, of energy resiliency.
What began as a tool to ensure that building owners get their money’s worth from design and construction professionals, commissioning is now known to be the most cost-effective measure available for reducing energy use, lowering costs and mitigating greenhouse gas emissions in buildings. A recent meta-analysis by Lawrence Berkeley National Laboratory found that Re/Retro-commissioning yields a median 16% energy savings with a payback time of 1.1 years for a cash-on-cash return of 91%.
Increasingly, Cx/RCx is the direct focus of government policy aimed at boosting energy efficiency in the built environment. Over the past decade, a series of Federal laws, executive orders and other regulations have resulted in requirements for commissioning and retro-commissioning in certain Federal buildings. The results of these policies have been to improve Federal energy management, while providing an instance of leadership-by-example that has increased the profile of Cx/RCx elsewhere.
Cx/RCx has the potential to save the Federal Government more than $30 billion a year in energy costs by 2030.[i] As a result of recent market trends as well as government policy aimed at capturing such benefits, the secret of re/retro-commissioning is out. Continuing to overlook this cost-effective quality assurance tool could not only be unlawful, but bad business.
