Q

What is an efficiency factor?

A
  • How efficient the floor is
  • Net/total occupant area
  • Ranges from 0.6 - 0.8
  • Includes columns, secondary circulation, etc..
  • Take the NET and divide by GROSS

400 SF (Net) ÷ 500 SF (UA) = .80 EF

Q

What is a load factor?

A

Ratio between Usable area and Gross area
* Take the Gross (total area or Rentable) and divide by the Usable (or occupant)

550 SF (RA) ÷ 500 SF (UA) = 1.10 LF

Q

General planning “rule of thumb,” Circulation Area comprises roughly what % of the total Usabel area?

25
Q

The Circulation Multiplier is used during the planning process to determine the total of what?

A

Usable area

26
The Circulation Multiplier is used during the planning process to determine the total of what?
Usable area
27
Circulation Factor represents the percentage of what?
Usable area space that consists of Circulation Area
28
The ratio of Open to Enclosed workspaces has the most consistent correlation to the required amount of what?
Circulation area
29
As the portion of open work-spaces increases, what will also correspondingly increase?
Circulation Multiplier
30
How to calculate rentable area
* Divide net area by EF * Mulitply by LF
31
Who is respobsible for calculating the load factor?
Building owner
32
What is Legacy Method A?
* The rentable area divided by the usable area for each floor * Calculates individual load factors for each floor according to floor configuration | Load factors PER floor method
33
What is Legacy Method B?
* The net area divided byusable area instead of the R/U ratio rentable area divided by usable area | Single load factor PER building method
34
# Residential SF For residential square footages, ALL habitable rooms must be a minimum of how many squaret feet, except kitchens?
70 SF | IBC 1207.1
35
# Residential SF What is the minimum room size a habitable room?
7' x 10' | 70 SF
36
# Residential SF One room must be at least how many square feet?
120 SF | IBC 1207.3
37
# Residential SF Kitchens require a MIN of __________ clear passageway between appliances and wall or counters
36" | IBC 1207.1
38
# Residential SF Bathrooms and Showers Clearances example
Please note these are MINIMUM dimensions
39
# Residential SF What is the MIN ceiling height in basements and bathrooms?
6' - 8"
40
# Residential SF What is the MIN ceiling height everyhwere else, except the basement and bathroom?
7' -0"
41
# Residential SF What is the allowed measurement in a basement to teh bottom of a beam or girder?
6' - 4" | IBC 1207.2
42
# Residential SF Spaces with ceilings lower than 5' are not considered what?
Habitable | IBC 1207.2
43
# Residential SF Ceiling height example
44
What is a boundary area?
The peripheral extend of all measured areas
45
If the boundary area line differs from one side of the column to the other, it is adjusted where?
At the center of the column width
46
In a multitenant floor plan, is the lobby considered part of the USF?
NO, the lobby is an exclusion of the USF because it is shared by ALL tenants
47
As a single tenant floor, is the lobby considered part of the USF?
YES
48
In a mult-story/multi-tenant floor, is the circulation space considered part of the rentable area?
YES, but only a prorated percentage is added to the rent
49
What is Circulation AREA?
This area is the SF dedicated to circulation within a tenant space * It is NOT a percentage or factor * It can be calculated by subtacting the net area from the usable area | 500 SF (UA) - 400 SF (NA) = 100 SF of circulation or CA
50
What is Circulation MULTIPLIER?
This number is a proportion of open (circulation) to enclosed spaces (offices/program). * ONLY applied to NET area | 400 SF (NA) ÷ 100 SF (CA) = 4.0 -This is the CM. (100 x 4 = 400SF)
51
Circulation can be added to Net assignable Area (NA) to get the what area?
USABLE * 400 SF (NA) + 100 SF (CA) = 500 SF (UA) -this is if you only get SQ FT and no factor or percentage to multiply
52
Example of the calculations going backwards (from large to small)
To calculate backwards. R/A ÷ LF = Usable (or Gross) 7,200 ÷1.2 = 6,000 SF (Usable) Now with the Usable (Occupant or Gross) area you need to arrive at the Net Area Usable (Gross) area x EF = Net 6,000 SF (usable or occupant gross area) x .75 (EF) = 4,500 SF (net area/assignable area)
53
NSF x CM =
USF
