fies for one of the exceptions under Section 9.1.1 or 9.4.5-

9.4.5 Exterior Building Lighting Power. T}:re total exte-

rior lighting power allowance for all exterior building appli-

cations is the sum of the individual lighting power densities

9.5 Building Area Method Compliance Path

9.5.f Building Area Method of Calculating Interior

Lighting PowerAllowance. Use the following steps to deter-

mine the interior lighting power allowance by the Building

Area Method:

a. Determine the appropriate building area type from

Table 9.5.1 and the allowed LPD (watts per turit atea)

from the "Building Area Method" column. For buildingarea types not listed, selection of a reasonably equivalent

type shall be permitted.

b. Determine the gross lighted floor area (square feet) of the

building area type.

listed, the specific building area type shall apply.

c. Multiply the gross lighted floor areas of the building area

type(s) times the LPD.

d. Tlne interior lightingpower allowancefot the building is the

sum of the lighting power allowances of all building area

types. Trade-offs among building area types are permitted

provided that the total installed interior lighting power does

not exceed the interior lighting power allowance.

9.6 Alternative Compliance Path: Space-by-SpaceMethod

9.6.1 Space-by-Space Method of Calculating Interior

Lighting Power Allowance. Use the following steps to deter-

mine the interior lighting power allowance by the Space-by-Space Method:

a. Determine the appropriate building type from Table 9.6.I.For building types not listed, selection of a reasonablyequivalent type shall be permiued.

b. For each space enclosed by partitions 80% or greater thanceiling height, determine the gross interior floor area bymeasuring to the center of the partition wall. Include thefloor area of balconies or other projections. Retail spacesdo not have to comply with the 80o/o pattition heightrequirements.

c. Determine the interior lighting power allowance by

using the columns designated Space-by-Space Method

in Table 9.6.L Multiply the floor area(s) of the space(s)times the allowed LPD for the space type that mostclosely represents the proposed use of the space(s). Theproduct is the lighting power allowance for the space(s).For space types not listed, selection of a reasonableequivalent category shall be permitted.

d. The interior lighting power allowance is the stxnof light-ing power allowances of all spaces. Trade-offs among

spaces are permitted provided that the total installed inte-rior lighting power does not exceed the interior lightingpower allowance.

9.6.2 Additional Interior Lighting Power. When using

the Space-by-Space Method, an increase in the interior light-

ing power allowance is allowed for specific lighting {qr.:tions. Additional power shall be allowed only if the specifiedlighting is installed and automatically controlled, separatelyfrom the general lighting, to be turned offduring nonbusinesshours. This additional power shall be used only for the speci-

fied luminaires and shall not be used for any other purpose.

An increase in the interior lighting power allowance is

permitted in the following cases:

a. For spaces in which lighting is specified to be installed in

addition to the general lighting for the purpose of decora-tive appearance, such as chandelier-type luminaries or

sconces or for highlighting art or exhibits, provided thatthe additional hgfrinfpo*it shall not r""r.d 1.0 Wft2 ofsuch spaces.

b. For lighting equipment installed in sales areas and specif-ically designed and directed to highlight merchandise,calculate the additional lighting pow€r as follows:

Additional Interior Lighting Power Allowance :

1O.2 - Definit ion of Compliance Paths

ANSVASHRAE/IESNA Standard 90.1-2007

dry-type transformer: a transformer in which the core

and coils are in a gaseous or dry compound.

liquid-immersed transformer: a transformer rn which

the core and coils are immersed in an insulating liquid.

U-factor (thermal trunsmittance).' heat transmission in unit time

through unit area of a material or construction andthe boundary

air films, induced by unit temperature difference between the

environments on each side. Units of U are Btu/h'ft2'"F.

unmet load hour: an hour in which one or more zones is

outside of the thermostat setpoint range.

unconditioned space: see space.

unenclosed space: a space that is not an enclosed space.

unitary cooling equipmenl.'one ormore factory-made assem-

blies that normally include an evaporator or cooling coil and

a compressor and condenser combination. Units that perform

a heating function are also included.

unitary heatpump.'one ormore factory-made assemblies that

normally include an indoor conditioning coil, compressor(s),

and an outdoor refrigerant-to-air coil or refrigerant-to-water

heat exchanger. These units provide both heating and cooling

functions.

variable-qir-volume (VAU system: HVAC system that

controls the dry-bulb temperature within a space by varying

the volumetric flow ofheated or cooled supply air to the space.

vent damper: a device intended for installation in the venting

system of an individual, automatically operated, fossil-fuel-

fired appliance in the outlet or downstream of the appliance

draft control device, which is designed to automatically open

the venting system when the appliance is in operation and to

automatically close offthe venting system when the appliance

is in a standby or shutdown condition.

ventilation: the process of supplying or removing air by natu-

ral or mechanical means to or from any space. Such air is not

required to have been conditioned.

vertical fenestration : see fenestration.

voltage drop: a decrease in voltage caused by losses in the

lines connecting the power source to the load.

wall: that portion of the building envelope, including opaque

area and fenestration, that is vertical or tilted at an angle of 60

degrees from horizontal or greater. This includes above- and

below-grade walls, between floor spandrels, peripheral edges

of floors, and foundation walls. For the purposes of determin-

ing building envelope requirements, the classifications are

defined as follows:

above-grade wall: a wall that is not a below-grade wall.

below-grade wall: that portion of a wall in the buildingenvelope that is entirely below the finish grade and in

contact with the ground.

l4

mass wall: a wall with an HC exceeding (1) 7 Btu/#''F

or (2) 5 Btu/d''F, provided that the wall has a material

unit weight not greater than I2Olblft3.

metal buitding wall: a wall whose structure consists of

metal spanning members supported by steel structural

members (i.e., does not include spandrel glass or metal

panels in curtain wall systems).

steel-framedwall: awall with a cavity (insulated or other-

wise) whose exterior surfaces are separatedby steel fram-

ing members (i.e., typical steel studwalls and curtain wall

systems).

wood-framed and other walls: all other wall types,

including wood stud walls.

wall areargrross.' the area of the wall measured on the exterior

face from the top of the floor to the bottom of the roof.

narm-up: increase in space temperature to occupied setpoint

after aperiod of shutdown or setback.

water heafer.' vessel in which water is heated and is withdrawn

for use external to the system.

wood-framed und other walls: see wall.

wood-framed and other floors: see floor.

zone, HVAC: a space or group of spaces within a building with

heating and cooling requirements that are sufficiently similar

so that desired conditions (e.g., temperature) can be main-

tained throughout using a single sensor (e.9., thermostat or

temperature sensor).
