Question
**Problem: Determining RCR Value for Corridor Lighting** A corridor is 8 ft by 60 ft with a 10 ft ceiling. You want to determine the average illuminance on the floor from recessed luminaires. What is the RCR value that you will use to determine the appropriate luminaire CU? **RCR = __________** --- *Explanation:* The RCR (Room Cavity Ratio) is a metric used in lighting design to help calculate the average illuminance required in a space. It is particularly useful when designing lighting layouts for specific areas such as corridors. *Formula to calculate RCR:* \[ RCR = \frac{5 \times (Ceiling Height - Work Plane Height) \times (Length + Width)}{Length \times Width} \] In this scenario: - Ceiling Height = 10 ft - Corridor dimensions = 8 ft by 60 ft - Work Plane Height is typically 2.5 ft for floor calculations in corridors (though not given here, it is a standard assumption). Plug these values into the formula to find the RCR.
