**Determining Correct Square Footage**

When entering the square footage allocated to a particular Service Center Use Rate, you must keep the following requirements in mind:

- If the space is used for more than one activity, you must base the square footage on the
**percent of time**spent on the particular service rather than any actual square footage of space used for the service.**Example 1:**An 80 square foot space is being used for a number activities that include the following:- 40% of time spent on internal college research activities
- 35% of time spent on teaching activities (required lab work for students)
- 25% of time spent on providing
**services to other university departments**

The Service Center Use rate square footage would be 20 square feet (25% of 80 square feet).

- You
**cannot allocate more than 100% of the actual square footage**of a room that is used in the Service center calculation.**Example 2:**A 100 square foot space is being used for 5 Service Center services (with 5 separate rates) and no other activities. Each activity uses virtually all of the space, but you must divide each square foot allocation based on the percentage of time used by each activity so that the total square footage does not exceed 100% of the room. Examples of two types of calculations follow:

- 20% of time spent on Rate 1 translates to 20 square feet
- 30% of time spent on Rate 2 translates to 30 square feet
- 20% of time spent on Rate 3 translates to 20 square feet
- 15% of time spent on Rate 4 translates to 15 square feet
- 15% of time spent on Rate 5 translates to 15 square feet
- 100% total translates to 100 square feet
**– or-** - You could allocate 20 square feet (20% usage) to each rate if the usage was virtually equal among all five services.
