be provided to the building owner. The manual shall be in accordance with industry accepted
standards.
g. sec. 1416.3.3. Systems, Equipment and Controls Functional'festing: FIVAC equipment and control
systems shall be tested [o ensure that control devices, components, equipment and systems are
glibrated, adjusted and operate in accordance with approved plans and specifications.
h. sec. 1416.2.4.4 Systenvs Operational Training: The training of the maintenance staff for tech
equipment type and/or system shall include the following:
1. Review of systems documentation.
2. Hands on demonstration of all nomtal maintenance procedure, normal operating modes, and all
emergency shutdown and start-up procedures.
3. LIGHTING: Lighting Power Allowance used for compliance, see Lighting Summary.
NOTE: Exterior Tradable lighting was not calculated for the apartment huildings (doors) or apartment
building landscaping; [he Non-Tradable Lighting (facade) for the apatvttent buildings was not
calculated either, The Community Building landscaped area, walkways and parking/drives
were calculated for the entire site. Tradable and Non-Tradable Lighting Allowancu~s were
calculated for the Cornmuniry Building. No Site Lighting was shown on the plans reviewed. The
Apartment huilding Tradable and Nnn-Tradable Allowances can be calculated from the
information on Table 15-2B located on the back of the Exterior Lighting Summary if more
wattage is needed. The allowable wattage includes ballad loads.
Tradable wattage can be used anywhere on site; Non-Tradable wattage can only be used for
facade lighting.
a. sec. 1513.3 Daylight Zone Control: All daylighted zones adjacent to vertical glazing shall be provided
with individual controls, or daylight-oroccupant-sensing automatic controls, which control the lights
independent of general area lighting. Dwelling units are exempt.
The Daylight Zone for vertical glazing is defined as Primary Zone (extends into the space a distance
equal to the window head height) end Secondary Zone (extends an additional distance past the edge
of the Primary Zone equal to the window head height or to the nearest ceiling height opaque partition,
whichever is less. The width of the daylight zone is assumed to be the width of the glaung plus two
fee[ on each side.
Primary and Secondary Zones shall be controlled separately.
Automatic daylight sensing controls shall be capable of reducing the light output of the controlled
luminainu while maintaining a uniform level of luminance by tither.
1. Comtinuous dimming to at least 20°h light output; or
2. Step switching of each lamp in individual luminaires -switching alternate luminaires is not
permitted except with single lamp luminaires: or
3. Step dimming by reducing the output of all the lamps in individual luminaries by at least 50%.
Automatic daylight controls shall control only the luminaries within the daylighted area and
incorporate time delay circuits to prevent cycling of light Level changes of less than three minutes.
Exceptions: The followimg spaces arc exempt fmm daylighting control providmg they have an
occupancy sensor.

comply with section 1513.6.1. For other spaces, automatic controls may be an occupancy
sensor, time switch or other device capable of automatically shutting off lighting.
EXCEPTION: Dwelling units
d. sec. 1513.6.1 Occupancy Sensors: Occupancy sensors shall be capable of awomaticaIfy taming off
all the lights in an area no more than 30 minutes after the area has been vacated. Light fixtures con-
tolled by occupancy sensors shall have awall-mounted, manual switch capable of taming off lights
whrn the space is occupied.
e. sec. 1 S 13.6.2 Automatic Time Switches: Automatic time switches shall have a minimum 7 day clock
and be capable of being set for 7 different day types per weds and incorporate an automatic holiday
"shut-off' feature, which turns off all loads for at least 24 hours and then resumes normal scheduled
operations. Automatic time switches shall also have program back-up capabilities, which prevent the
loss of program and time settings for az Icast 10 hours, if power is interrupted.
Automatic time switches shall incorporate an over-ride switching device which:
I. is readily accessible;
2. is located so that a person using the device can sec the lights or Ore areas controlled by the switch,
or so that the area being illuminated is annunciated;
3. is manually opcretcd;
4. allows the lighting to remain on no more than 2 hours when an over-ride is initiated.
f. sec. 1513.7 Commissioning Requirements: For lighting controls which include daylight or occupant
sensing automate controls, automatic shut-off controls, occupancy sensors, or autonwtic time switch-
es, the lighting comrols shall be tested to insure that control devices, components, equipment and sys-
tams are calibrated, adjusted and operate in accordance with approved plans and specifications. Se-
quences of operation shall be functionally tested to ensure they operate in accordance with approved
plans and specifications. A complete report of test procedures and results shall be prepared and filed
with the owner.
