Lean Retro-Commissioning: Improving the Effectiveness of the Utility Sponsored Retro-Commissioning Process

摘要

Retro-commissioning (RCx) can be largely defined as the process of improving thernoperational and maintenance aspects of an existing building. As these types of measures arerntypically embedded in the behavior and sequences of daily building operation, determining areasrnof improvement requires a systematic process of analysis, testing, implementation, andrnverification. There are several models utilized across the industry that range from a "find-andfix"rnapproach that focuses on identifying opportunities and immediately fixing them to arndetailed analysis approach centered on quantifying the measureable impacts of each opportunityrnprior to implementing the measure. This paper is aimed at achieving a structured middle-groundrnbetween these two approaches that integrates the "find-and-fix" approach into the traditionalrnprocess of detailed analysis followed by implementation. Details provided in the followingrnsections are from the perspective of a utility sponsored RCx program that requires a level of rigorrnin quantifying the impacts necessary for resource planning. While such an approach may havernbeen implemented on an ad-hoc basis in many utility sponsored RCx projects, this paper offers arnstructured method that improvises the traditional process to align with the end goal of effectivernyet verifiable and timely implementation. Some of the key benefits attributable to our approachrnand elaborated in the following sections of the paper are increased project momentum, increasedrncertainty of project completion, a reduction in project completion time by about 50% and morerninvolvement in implementation from all the stake holders.
