Performance Measurement

Energy Efficiency and Performance Measurement

Laboratory facilities are unique environments that require dynamic operation of various interactive systems, in contrast to standard office buildings. These dynamic, interactive systems can include variable air volume (VAV) supply, fume hoods, and exhaust systems that require positive and negative pressure differentials between laboratories and support spaces. Therefore, commissioning should evaluate and measure the entire facility's performance. The Performance Measurement phase of commissioning assesses the system's actual performance and functioning status and compares the results with the design specification. Baseline performance data are compiled to verify the design performance predictions and to assist in the efficiency assurance commissioning phase. All critical components are tested to determine their performance, suitability, and reliability. "Stress conditions" are created to determine the laboratory systems' control ranges. A fundamental concern is to determine the facility's stability and ability to recover from periods of transition and emergency. Therefore, control sequences, room pressure control, and fume hood containment systems are closely and thoroughly verified.
