Tightening the Constraints Faster: A Statistical Process Control Approach to Commissioning in Buildings.

摘要

Statistical Process control is a technique often used in manufacturing in order torndetermine whether a process is changing based upon most recent measurements. This paper willrnoutline a preliminary methodology for determining when building operation parameters havernchanged, attempt to identify them, and suggest solutions, given a top-down monitoringrnmethodology combined with a bottom-up fault diagnostics approach. The approach in this paperrnwill combine the use of free open-source graphical analytic tools with whole building intervalrnenergy consumption data for the development of control charts. This technique leveragesrnadvancements in computing and smart grid technology along with industrial process qualityrncontrol methods to facilitate fault detection and diagnostics in commercial buildings. Thisrntechnique will be discussed, from technical requirements to implementation, with specialrnattention paid to the progress of a test case deployment.
