  • Areas designated as security or emergency areas that are required to be
    continuously lighted.
  • Interior exit stairways, interior exit ramps and exit passageways.
  • Emergency egress lighting that is normally off
54
Q

Lighting Needs: Watts per SQ FT
This is one of the most simple calculations to do and memorize. It consists of Dividing the total watts by the total square footage of an area

A

Watts per SF = Total watts ÷ Total SF

Example:

A 2,010 SF room has lamps with a wattage of 6,000 W total

6,000 ÷ 2010 = 2.99 W/SF

The formula can be reversed to find the total wattage for the room.

55
Q

Lighting Load
This formula is used to determine how many circuits are required and how many amps per circuit

A

A(mps) = W(atts) ÷ V(olts)

This formula is used to determine how many watts can be on a circuit based on voltage

W(atts) = A(mps) x V(olts)

This formula is used determine the voltage in a circuit given watts and amps

V(olts) = W(atts) ÷ A(mps)

56
Q

FC Needed (level of brightness)

Lumen Method

This method is used to find how many footcandles (FC) are needed in a room

A

E= Illuminance (or footcandles)

E = Total Lumens ÷ AREA

= lamp lumens x # lamps x # luminaires

AREA

57
Q

Lumen Method Example

A

Car Showroom

You know the lamps specified have 2,200 Lumens each

There are 2 lamps per luminaire.

There are 14 luminaires total.

The room is 25 x 30

How many FC are in this room?

Let’s do the math

2,200 x 2 x 14 = 61,600 Lumens

61,600 ÷ 750 SF (25x30)

Total = 82 FC

The answer is 82 FC (sf) in the room.
