Observation of the systems during Institutional Tuning

Step 1: Determination of maximum power or output prior to Institutional Tuning

(a) Set all lighting controls to provide maximum output of the tested system without applying the limits specified for institutional tuning.

(b) Measure the full light output at a location where the illuminance is due to the controlled lighting, or measure the power draw of the controlled lighting.

Step 2: Institutional Tuning and Post-tuning Measurement

(a) Apply the limits specified for instutional tuning to the lighting system. Do not alter any other control settings.

(b) Verify the light or power reduction after institutional tuning by measuring the light output at the same location as in Step 1 or measure the power draw of the same circuit as in Step 1.

(c) If the light output or power draw measured in Step 2(b) is 85% or less of the light output or power draw measured in Step 1(b), the system passes this test; otherwise the system fails this test.

Verification of systems already tuned

Step 1: Measurement of tuned lighting system

(a) Set all lighting controls except Institutional Tuning controls to provide maximum output of tested system. Controls set to maximum light output include but not limited to: manual dimmers, multilevel occupancy sensing, and automatic daylighting controls.

(b) Measure full light output at location where most of the illuminance is due to the controlled lighting or measure power draw of the controlled lighting.

Step 2: Measurement of lighting system with Institutional Tuning overriden

(b) Measure full light output at the same location as in Step 1 or measure the power draw of the same circuit as in Step 1.

(c) If the light output or power draw measured in Step 1(b) is 85% or less of the light output or power draw measured in Step 2(b), the system passes this test; otherwise the system fails this test.

Step 3: Restore Institutional Tuning settings

(a) If tested system passed the test in Step 2, restore Institutional Tuning settings.
