NEW QUESTION # 149
A tenant of a new office building will require 100 workstations per floor. Each floor will have two bathroom facilities and one conference room. How many lighting control devices with at least three lighting levels per floor are required to comply with Indoor Environmental Quality Credit, Interior Lighting, Option 1. Lighting Control?
- A. 93 lighting control devices
- B. 91 lighting control devices
- C. 103 lighting control devices
- D. 100 lighting control devices
Answer: A
Explanation:
Explanation
To comply with Indoor Environmental Quality Credit, Interior Lighting, Option 1. Lighting Control, the tenant of a new office building will require93 lighting control deviceswith at least three lighting levels per floor.This is because the credit requires that at least 90% of individual occupant spaces have lighting controls that enable occupants to adjust the lighting to suit their individual tasks and preferences1.The credit also requires that all shared multioccupant spaces have lighting controls that enable adjustments that meet the needs of the group1.According to the LEED BD+C Reference Guide, an individual occupant space is defined as an enclosed space or an open space that is occupied by one person and is at least 50 square feet (4.6 square meters) in area1.A shared multioccupant space is defined as an enclosed or open space that is occupied by more than one person and is at least 100 square feet (9.3 square meters) in area1.
Based on the given information, each workstation can be considered as an individual occupant space, and each bathroom facility and conference room can be considered as a shared multioccupant space. Therefore, the number of lighting control devices per floor can be calculated as follows:
* For the 100 workstations, 90% of them need lighting controls, which is 90 workstations. Each workstation needs one lighting control device, so the total number of lighting control devices for the workstations is 90.
* For the two bathroom facilities, each facility needs one lighting control device, so the total number of lighting control devices for the bathroom facilities is 2.
* For the one conference room, one lighting control device is needed, so the total number of lighting control devices for the conference room is 1.
The total number of lighting control devices per floor is then 90 + 2 + 1 =93.
