(5) Find the number of spaces of that type required (N). Use the formula N = c/uh in which:
.
c = total hours per week space type is required as discussed in (4)
u = room utilization rate: the fraction of time a space would be used while the ACES Center is in
operation; normally u = 0.8
h = hours per week that ACES Center will normally operate.
If N is a fraction or a mixed number, round up to the nearest whole integer. Completion of this step will
indicate the number of each type of instructional space required. Normally, a minimum of one MOS
Library and Self-Paced Instruction area, and one Testing Room will be required. However, the Testing
Room may be doubly used as classrooms reducing the number of those spaces which would otherwise
be required.
(6) Survey Existing Suitable Facilities. Existing spaces which are or can be made available for
ACES activities should have convenient access to necessary support facilities (toilets, storage, etc.).
These spaces should be listed in two groups:
--
(a) Usable Spaces: within 8 minutes walking distance (2,000 ft.) of other ACES activities especially
instructional activities, to permit movement within 10-minute class break; with no major functional
problems and compatible with space allocation and other criteria in Chapter 4; and with no major
problems related to operation, supervision, or availability. An Arts and Crafts Center or Auto Craft
Center, in close proximity, should be considered in this group, especially with regard to providing
suitable shop spaces.
(b) Conditionally Usable Spaces: over 8 minutes walk to other ACES activities but usable for
courses which do not require movement to and from rest of ACES Center; and/or with functional,
operational, supervision, or availability problems that permit restricted use or require extensive
renovation.
(7) Determine Requirements for New Instructional Space. Subtract existing usable spaces from
required spaces. Be sure that the spaces which are subtracted are compatible with the Individual
Space Criteria for each type of instructional space they are to replace. Multiply the number of spaces
required for each space type times the NASF space allocated for that type in Chapter 4.
(8) Determine Space Requirements for Staff. Determine staff space requirements in relation to the
staff authorized and the Individual Space Criteria for staff spaces in Chapter 4. Subtract existing
usable spaces as determined according to (6). Be sure that existing facilities contemplated for staff use
are compatible with effective ACES operation as certain staff offices may have to be centrally located.
