Ambient Lighting and Wall Washing
- Lighting Scene Control: Each Conference Room has four lighting scenes to provide appropriate lighting levels for different types of interactive meetings and multi-media presentations.
- Lighting Control Partitioning: The large Conference Rooms have retractable partition walls to divide the space into two smaller conference rooms. Two scene controllers in each Conference Room offer 3-way lighting control when the partition wall is open, and divided lighting control when the partition wall is closed. The partitioning feature also links or divides occupancy sensors to adapt to an opened or closed partition wall.
- A/V Interface: Users can control the lighting from the Audio/Visual touch screen controller with a communication link to the lighting control system.
- Occupancy Sensors: When the Conference Room has been vacated for a certain time period, the lights will automatically turn off.
- Daylight Dimming: When daylight dimming is active, the dimmers respond to input from a photo sensor to maintain 25 footcandles on the table tops.
Lighting Scene Control with Room Partitioning
- Four lighting presets in each conference room provide a variety of bright and dim lighting.
A/V Interface
- Lighting scenes can be activated from the A/V controller.
Occupancy Sensors
- Manual-On/Auto-Off operation.
Daylight Dimming
- Maintains 25 footcandles on table tops.

Lighting Energy Use
- ASHRAE 90.1 2004 Allows: 1.30 W/SF
- Installed Lighting Power Density: 0.51 W/SF
- Conference Room Square Footage: 5,500 SF
- Connected Lighting Load: 2,800 Watts
- Predicted Annual Lighting Energy: (Both Baseline & Convia are based on installed loads)
- Baseline Controls: 6,200 kWh/yr (Assumes occupancy sensors with Auto-On/Auto-Off control)
- Convia Controls: 1,800 kWh/yr (71% below Baseline Controls)
