METHOD B - SCENARIO 2. ONE STORY, MULTIPLE OCCUPANTS
Determining Rentable Area in an lndustrial Buildinq
Using the Drip Line Methodology
One Story, Multiple Occupants
Refer to lllustraiion 82.1 and lllustration 82.2, and follow
these steps to determine the rentable area of the building:
'1.
Determine the drip line area of the full floor bounded by
the drip line. Refer to lllustration 2 and lllustration 82,1.
2. Determine the floor area of any permanent mezzanines
or unclassified mezzanines bounded by the drip line
at the building perimeter. Referto lllustration 3 and
lllustration 82.1.
3. Determine the total drip line area of ihe building by
adding the full floor drip line area from step # l to
the mezzanine area from step #2. This will be the
drip line area of the building.
4. ldentify all space located on either the full floor or a
mezzanine that is finished and measure its floor area
to the centerline of walls between it and adiacent
unfinished areas.
5. ldentify and measure any areas requiring disclosure,
including
. Restricled headroom area
. Unclassified mezzanines
. Connectors or Þortions thereof
ô. These âreas represent the drip line area of the building
The following steps will calculaie the rentable area
of the building and each of its occupants. Refer to
lllu F2.2 and classify all areas within the drip
line on the floor and all mezzanines except iemporary
mezzanines into one of the following five classes of
space:
. Major vertical penetrations
. Occupant areas
. Building amenitv areas
. Building service areas
. Floor service areas
7. Determine the boundaries between each class of space
using the wall priority diagram shown in the Appendix.
B, Calculate the areas of each class and category of space
and tabulate them using the global summary of areas
as shown below including separate occupant areas
for each occupant measured to the centerline of their
demising walls,
9. Within each class of space, separately delineate and
calculate rentable areas of any space that are finished
or require disclosure.
A tabulation of the results of applying these five steps to the
building shown in lllustration 82.1 is as follows
