A schematic of my lighting plan is shown below:

My panel schedules are as follows:

I chose to model lighting and power elements on the 5th floor of my building, as that was the most complex location due to the variability of spaces and increased square footage. A breakdown of my power and lighting load analysis is captured below.

  • your power system elements
  1. Receptacles/outlets
    1. In the office and conference room, I placed a combination of duplex and quadruplex receptacles (2 ea/room) approximately every 6 ft
    2. In the restrooms, I placed 1 quad receptacle w/ GFCI
    3. In the mechanical rooms, I placed 4 quad receptacles w/ GFCI
    4. In the exhibit spaces, I primarily placed quad receptacles (standard) on the floor, but limited the overall amount as I felt that those spaces should have reduced plug load demands since they are more transient in nature. For those spaces I pushed the spacing between elements to 12’
  2. Power Circuits
    1. I have 6 circuits per panel that feed the receptacles by room/space
  3. Power Panels
    1. I have 2 100A panels housed in mechanical rooms in each of the cores of my building. Each panels hosts the respective circuits on its side of the building, and has the capacity to take an additional 50-75A of load if needed for exhibits or displays
  • your lighting system elements
  1. Lighting Fixtures
    1. In the office and conference room, I placed recessed cans to provide ample task lighting for those workspaces, since they are less exposed to natural lighting
    2. In the exhibition spaces and education areas, I placed recessed high-efficiency louvers approximately every 6-10 ft to ensure proper coverage. Since this floor receives the most amount of daylight relative to the other spaces in my building I didn’t want to oversaturate it with a substantial amount of lighting fixtures, as that would counteract my sustainability goals for the space
  2. Switches
    1. I have a mixture of 3-way and dimmer switches placed on the walls at the entrance of every room. For the exhibition spaces, the switches are housed immediately outside of the stairwell and elevator
  3. Lighting Circuits
    1. Similar to the receptacles, each lighting circuit is is divided by room and powered by the respective panel on that side of the building
