5 SCHEDULING – ALARM PROCESSING – RUN ANALYSIS
1. Describe how normal schedules, annual holiday schedules and temporary schedules are
implemented and how they are used.
2. Describe options on how alarms are can be filtered, processed and distributed.
3. Provide a screen shot of a run time totalizer showing start and stop times, durations and
any other features.
6 F.D.D. AND DATA ANALYTICS
The City seeks to improve energy efficiency and reduce operating costs by implementing
automated measures to identify mechanical system operational faults. Examples of a Fault
Detection and Diagnostics (FDD) implementation may include for example:







identifying air handler operation that has not taken full advantage of free cooling
identifying excessive equipment runtime beyond present daily and weekly limits
Valve leak-by
Damper operational fault
Oscillating Control Loop
Setpoint out of threshold range
Statistical control accuracy index for terminal equipment
6.1
Data Analysis Language
To carry out the various required analyses a Data Analysis Language is required.
1. Provide information on the language and programming environment for constructions
rules for analyzing system operation.
2. Identify the manufacturer of the Data Analytics hardware and software.
3. Describe how the system may allow queries to be performed to facilitate data analysis
without the need for manual data normalization, manual interpolation to compensate for
missing samples, different sample frequencies or different sample timing.
4. Describe how date and time formats are handled when exporting to Excel.
