6 How do you know your system is working properly Night walks Override Reports Controls Maintenance Spending hours looking through trend logs Watching the utility bill 5

7 Condition Based Maintenance 6

8 How do you know your system is working properly 7

9 Goals of Fault Detection Reduce energy costs Reduce comfort complaints Maximize the efficiency of the equipment Manage/Measure KPI s Visualize information 8

10 FAULT DETECTION AND DIAGNOSTICS CONNECTING EQUIPMENT TO ANALYSIS SOFTWARE FOR REAL TIME PERFORMANCE MANAGEMENT RESULTS IN PRODUCTIVITY GAINS OVER TIME Fault Reporting Fault priority reports by custom priority and/or costs savings potential Ability to create custom reports Ad-hoc reporting Automatic daily, weekly reports Fault Detection & Diagnostics (FDD) Fault detection / diagnostics Pre-developed (canned) algorithms Allowance for flexible and customized fault rules by customer or system integrator Ability to define custom priorities of faults identified Monetization of faults with respect to utility cost avoidance Ability to show fault status indication (active, inactive, closed etc.) which can be changed by user Ability to add user comments per fault Ability to integrate into a CMMS software MONITORED- BASED CONTINUOUS COMMISSIOING Periodic retro-commissioning 9
