Chiller energy savings are achieved by comparing the initial energy consumption of a chiller system with its energy usage after implementing energy-efficient measures. The percentage of energy savings is calculated as the difference between initial and final consumption divided by the initial consumption, then multiplied by 100. This measurement helps assess the effectiveness of energy-saving strategies in reducing operational costs and environmental impact.
