Q

What is a load factor?

A

24
Q

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

A

20% - 40%

25
Q

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

A

Usable area

26
Q

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

A

Usable area

27
Q

Circulation Factor represents the percentage of what?

A

Usable area space that consists of Circulation Area

28
Q

The ratio of Open to Enclosed workspaces has the most
consistent correlation to the required amount of what?

A

Circulation area

29
Q

As the portion of open work-spaces increases, what will also correspondingly increase?

A

Circulation Multiplier

30
Q

How to calculate rentable area

A
  • Divide net area by EF
  • Mulitply by LF
31
Q

Who is respobsible for calculating the load factor?

A

Building owner

32
Q

What is Legacy Method A?

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
Q

What is Legacy Method B?

A
  • The net area divided byusable area instead of the R/U ratio rentable area divided by usable area

Single load factor PER building method

Q

Residential SF

For residential square footages, ALL habitable rooms must be a minimum of how many squaret feet, except kitchens?

A

70 SF

IBC 1207.1

35
Q

Residential SF

What is the minimum room size a habitable room?

A

7’ x 10’

70 SF

36
Q

Residential SF

One room must be at least how many square feet?

A

120 SF

IBC 1207.3

37
Q

Residential SF

Kitchens require a MIN of __________ clear passageway between appliances and wall or counters

A

36”

IBC 1207.1

38
Q

Residential SF

Bathrooms and Showers Clearances example

A

Please note these are MINIMUM dimensions

39
Q

Residential SF

What is the MIN ceiling height in basements and bathrooms?

A

6’ - 8”

40
Q

Residential SF

What is the MIN ceiling height everyhwere else, except the basement and bathroom?

A

7’ -0”

41
Q

Residential SF

What is the allowed measurement in a basement to teh bottom of a beam or girder?

A

6’ - 4”

IBC 1207.2

42
Q

Residential SF

Spaces with ceilings lower than 5’ are not considered what?

A

Habitable

IBC 1207.2

43
Q

Residential SF

Ceiling height example

A
44
Q

What is a boundary area?

A

The peripheral extend of all measured areas

45
Q

If the boundary area line differs from one side of the column to the other, it is adjusted where?

A

At the center of the column width

46
Q

In a multitenant floor plan, is the lobby considered part of the USF?

A

NO, the lobby is an exclusion of the USF because it is shared by ALL tenants

47
Q

As a single tenant floor, is the lobby considered part of the USF?

A

YES

48
Q

In a mult-story/multi-tenant floor, is the circulation space considered part of the rentable area?

A

YES, but only a prorated percentage is added to the rent

49
Q

What is Circulation AREA?

A

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
Q

What is Circulation MULTIPLIER?

A

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
Q

Circulation can be added to Net assignable Area (NA) to get the what area?

A

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
Q

Example of the calculations going backwards (from large to small)

A

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)
