Case Study: Critically Evaluating Replacement Chiller Options beyond Lifecycle Cost Analysis

This presentation covers the approach, methodology and lessons learned of a performance-based chiller retrofit project. The performance evaluation included a life-cycle cost assessment of replacement options that involved a data-driven energy model and an accurate understanding of the baseline energy consumption in the existing condition through a building survey and detailed trend analysis. Lessons learned from construction oversight and performance-based commissioning is also presented.
