Adapting to people & the environment

System Overview • Workspace specific • Quality illumination • Personal dimming control • Occupancy sensors • Daylight dimming • Peak load management • Scheduling/Reporting

Workspace specific lighting • One Ergolight per standard workstation • Positioned directly over work area • Puts light where it is needed

Standard troffer layout: 26 fixtures

Workspace specific layout: 13 fixtures

Application Photo

Quality Direct/Indirect Lighting • Center lamp distributes light upwards, reflects off ceiling • Provides uniform ambient light / Softens shadows • Eliminates cave-like room appearance • Outer lamps deliver extra light on desk-top for enhanced visibility • Louvers control glare on computer screens

Constant up-light in open spaces Up-light unaffected Personal Dimming Daylight Dimming Occupancy Sensing

Occupancy and daylight sensing • Overhead sensor location= reliable sensing • Gradually dims outer lamps to 10% after time delay • Holds at 10%, before turning lamps off • Over 30% energy savings in window adjacent locations • Gradual dimming avoids sudden changes in levels • Maintains constant light level at work plane

Personal Dimming Control • On-screen control panel • Users select preferred light level • Ceiling light stays constant

System-wide management • FM has full control over entire Ergolight network • Entire network can be gradually dimmed for load shedding • Events can be scheduled on daily/weekly/monthly basis

Detailed energy reporting

Load shedding and sensor commissioning • Avoid peak demand charges with load shedding • Commission sensors with the click of a mouse
