Low Ambient/ Task Office Lighting�•

Hypothesis: Save energy and maintain or improve occupant satisfaction by lighting the workstation desk top with task lighting, and reducing the ambient lighting.

�•

PG&E ET Assessments:�–

High Efficiency Office Low Ambient/Task Lighting: Large Office (Report #0819- www.etcc-ca.com).

�•

Heschong Mahone Group, Inc. (HMG)+ California Department of General Services (DGS), Clanton and Associates, CB Richard Ellis, California Energy Commission's Public Interest Energy Research (PIER) Program and the California Lighting Technology Center (CLTC).

Low Ambient/ Task Office Lighting

�•

IESNA Recommended Practice for Office Lighting

�–

“Lighting for visual tasks can be provided solely by general lighting, or, more appropriately, may be supplemented with localized task lighting. In the latter case, the general lighting can be at a lower level.” RP-1-04, p.9

�–

“Illuminance selection is solely for the task area. Additional lighting is always within the office environment for facial modeling, room surface luminances, and space appearance.” RP-1-04, p.9

April 29, 2010 27

Large Office - “Ziggurat Building” (California Department of General Services)

�•

Reduced ambient light level from 37fc to 17fc, increased task lighting.

�•

Lighting Power Density reduced from 1.5 to 0.66 = 56% savings.

�•

Occupant responses: As attractive, more comfortable, higher overall visual quality.

�•

9.1 yr. simple payback

April 29, 2010 28

Small Office: Encon Building

�•

Reduced ambient light levels from 33fc to 19fc, increased task light levels.

�•

Lighting Power Density (lighting w/sq.ft) reduced from 1.34 (existing) to 0.66: 51% savings.

�•

Title 24 remodel would have capped LPD at 1.21. 0.66 LPD represents 45% savings.

�•

Occupant responses: More attractive, more comfortable, higher overall visual quality.

�•

5.8 yr. simple payback.

SummaryBroad spectrum light sources provide equivalent or better visualperformance than the existing HPS luminaires. These alternative light sources provide lower glare and equivalent performance at a lower roadway illuminance level.This suggests that the broad spectrum light sources do provide additional information in the visual scene and a higher potential performance
