The energy performance of chillers is highly dependent on their operating conditions, making single-point measurements insufficient for accurately comparing the energy performance of different chillers or estimating the potential energy savings from chiller replacement. As chilled water production is a significant energy driver in buildings, it is a critical focus for energy service companies, building operators, and owners. Therefore, precise assessment and estimation of energy performance and potential savings are essential, given their influence on the financial viability of a project. This study aims to achieve three objectives through a case study: (1) measure the energy consumption and performance of two chillers operating simultaneously, (2) model the chillers using data obtained from an Internet of Things (IoT) platform, and (3) apply Measurement and Verification (M&V) techniques to compare energy performance and evaluate potential energy savings.
