Power System Elements:

In this phase of the design process, I focused on incorporating the essential power system elements into a small portion of my building model. This included placing electrical panels, receptacles, and connecting various components through power circuits. Key steps involved:

  1. Placing Electrical Panels:
    • I used a Lighting and Appliance Panel Board (400A) in the Guest Lobby and Kids Zone to manage power distribution efficiently.
  2. Adding Receptacles:
    • Duplex receptacles were placed strategically within the spaces to ensure accessibility and compliance with power requirements.
    • These receptacles were connected through power circuits to optimize energy distribution.
  3. Creating Power Circuits:
    • Each duplex receptacle was assigned to a circuit and linked to the Lighting and Appliance Panel Board.

Lighting System Elements:

To develop the lighting system, I placed and connected lighting fixtures, switches, and circuits to ensure proper illumination throughout the designated building area.

  1. Placing Lighting Fixtures:
    • I installed Sconce Light 100W fixtures to provide adequate lighting while maintaining energy efficiency.
    • The fixtures were distributed strategically to meet the illumination requirements of different spaces.
  2. Adding Switches:
    • Switches were positioned near doors to enhance accessibility and user convenience.
    • The placement followed ergonomic design principles to ensure ease of operation.
  3. Creating Lighting Circuits:
    • The lighting fixtures were assigned to circuits based on their functional zones.
    • Each circuit was linked to the electrical panel to ensure efficient power distribution and control.

Analyzing Illumination Levels:

  • I compared the estimated illumination values against target levels for different space types:
  • Space Type
    Target Illumination (Footcandles)
    Measured Illumination
    Guest Lobby
    40 fc
    52 fc
    Kids Zone
    40 fc
    47 fc
    Male Restroom
    18 fc
    22 fc
    Female Restroom
    18 fc
    18 fc
    ADA Restroom
    18 fc
    33 fc
  • Additional lighting fixtures were added where necessary to meet the required illumination standards.

By following these steps, I ensured that the lighting system met design standards while maintaining energy efficiency and usability.
