Test 150 AUDITORIUM APPLICATION WITH BAS COMPUTER SYSTEM - DESIGN TEST
1 OCCUPIED-UNOCCUPIED CONTROL:
The bas computer shall manage the (space, hours, transmitters) of occupied cycle operation based on 365 day calendar of events for use of the auditorium. The bas computer daily calendar (may, may not) be overridden to allow unscheduled and/or rescheduled use of the auditorium.
2 SPACE COOLING AND HEATING:
The bas computer shall provide (random, local, remote) trending of room thermostat temperature transmitter RT-1 data to indicate space temperature is within the design intent of [+ or -]1.5[degrees]F range. If the temperature range (fluctuates, remains, resets) beyond the [+ or -]1.5[degrees] range, an alarm shall be indicated back at the bas computer.
3 MONITORING AND MEASURING OUTDOOR AIR VENTILATION:
The bas computer shall provide remote trending of AHU outdoor air ventilation with flow measuring station FMS-1 indicating the design intent cfm (300 cfm outdoor air) at the bas computer. If the outdoor air fluctuates [+ or -] 10% of the (supply air, ventilation, air conditioning) range, an alarm shall be indicated back at the (supply fan, FMS-1, bas computer).
4 MONITORING AND MEASURING SUPPLY AIRFLOW:
Bas computer shall provide remote trending of AHU supply airflow with flow measuring station FMS-2 indicating design intent cfm (2,000 cfm constant supply airflow) at the (unit, bas computer, FMS-2). If the supply air fluctuates [+ or -] 10% (i.e., increase in static pressure due to dirty AHU filter), an alarm shall he indicated back at the bas computer.
Helpful Hints:
* There are several hvac system options, as well as numerous variations in auditorium design intent criteria. The design engineer needs to work closely with the owner representative to mutually agree upon the optimum system selection and space conditions for the auditorium.
* Refer to ASHRAE 2000 Systems and Equipment Handbook, Chapter 1 for system selection and analysis of the optimum hvac system for the auditorium application (i.e., central air system vs. rooftop hvac system) options.

Test 151 AUDITORIUM APPLICATION WITH BAS COMPUTER SYSTEM - FUNCTIONAL PERFORMANCE COMMISSIONING TEST
1 Set bas computer calendar to an occupied period of time. Verify that:
a. The supply air fan SAF-1 is (on, off, modulating) and the return air fan RAF-1 is (on, off, modulating).
b. Return air damper D-2 is (open, closed, modulating)
c. Outdoor air damper D-1 is (open, closed, modulating).
2 Set bas computer calendar to an unoccupied period of time. Verify that:
a. SAF-1 is off and the RAF-1 is off.
b. D-2 is (open, closed, modulating), outdoor air dampers D-1 and D-4, and exhaust air damper D-3 are (open, closed, modulating).
3 Override the bas computer calendar from unoccupied to occupied and add an unscheduled activity for the auditorium. Verify that:
a. SAF-1 (remains off, starts, varies flow) and the RAF-1 (remains off, starts, varies flow).
b. D-2 is (open, closed, modulating).
c. D-1 is (open, closed, modulating).
4 Reset room thermostat temperature transmitter RT-1 signal from 75[degrees] to (76[degrees], 74[degrees], 73[degrees]). Verify that:
a. The bas computer signals an alarm that space temperature has fluctuated beyond [+ or -]1.5[degrees] (setpoint, range, signal).
b. The AHU heating system is on, providing heat to bring space temperature back into design intent.
5 Reset flow-measuring station FMS-1 signal from design intent cfm of 300 cfm outdoor air to (315 cfm, 330 cfm, 345 cfm). Verify that:
a. The bas computer signals an alarm that outdoor air fluctuated beyond [+ or -] 10% of the ventilation range.
6 Release the overrides and verify the auditorium hvac system devices return to their normal positions and setpoints per the sequence of operation, based on the specific time-of-day system schedule.
Note: This functional performance test is only a part of the overall commissioning needed for this type of system.
