HGA Lighting Recommendations Based on GSA and ARRA Guidelines

LIGHTING SYSTEM OPTION #1

WORKSTATION- SPECIFIC LIGHTING USING DALI BALLASTS

Open Office Areas—

This lighting system would include one luminaire suspended above each workstation with separately controlled uplight and downlight components. The uplight component of the light fixture would vary by use of daylight dimming and scheduling of the facility. The downlight component of the fixture would be controlled by occupancy and the individual occupying the workstation. The Digital Addressable Lighting Interface (DALI) would provide a network of dimmable ballasts and individualized software control. The system can also output detailed energy consumption data reports and can assist maintenance by producing feedback for lamp outages. All spaces would require automatic shutoff by relay control system. For spaces with daylight access, photo sensor control would be required.

Private Office Areas—

The DALI system can be utilized in the enclosed office areas as well. The interaction between various ballasts and software enable the control system to be used with various luminaire types. All spaces would require automatic shutoff by either occupancy sensor or relay control system. For spaces with daylight access, photo sensor control would be required.

Non-Office Areas—

The interior lighting specification for non-office areas would vary through the specific needs of the space. Other luminaire types must be added as needed to achieve proper lighting quality criteria including but not limited to downlights, wall washers, wall sconces, etc. Lighting must comply with IESNA quality criteria as specified in DG-18 and must also comply with the energy savings objective listed below. All spaces would require automatic shutoff by either occupancy sensor or relay control system. For spaces with daylight access, photo sensor control would be required.

Conference Rooms—

Conference rooms require varying light levels with flexibility and dimmable lighting. Modular control panels with preset lighting zones would be used for rooms with multiple lighting types. All spaces would require automatic shutoff by relay control system.

Corridor and Core Walls—

Corridor lighting would consist of recessed high efficiency troffers. All spaces would require automatic shutoff by relay control system.

LIGHTING SYSTEM OPTION #2

TASK/AMBIENT LIGHTING APPROACH

Open Office Areas—

This lighting approach uses direct/indirect suspended pendants in continuous rows supplemented with local workstation task lighting (under cabinet lights and desk lamps). This system may be used with dimming ballasts and controls that allow individual customization of light levels in enclosed offices and zoning controls for groups, daylight harvesting. Open office areas would be controlled by zones, manually accessible by users. All spaces would require automatic shutoff by either occupancy sensor or relay control system. For spaces with daylight access, photo sensor control would be required.

Private Office Areas—

Open offices would use the same lighting concept as open office areas. All spaces would require automatic shutoff by either occupancy sensor or relay control system. For spaces with daylight access, photo sensor control would be required.

Non-Office Areas—

The interior lighting specification for non-office areas would vary through the specific needs of the space. Other luminaire types must be added as needed to achieve proper lighting quality criteria including but not limited to downlights, wall washers, wall sconces, etc. Lighting must comply with IESNA quality criteria as specified in DG-18 and must also comply with the energy savings objective listed below. All spaces would require automatic shutoff by either occupancy sensor or relay control system. For spaces with daylight access, photo sensor control would be required.

Conference Rooms—

Conference rooms require varying light levels with flexibility and dimmable lighting. Modular control panels with preset lighting zones would be used for rooms with multiple lighting types. All spaces would require automatic shutoff by relay control system.

Corridor and Core Walls—

LIGHTING SYSTEM OPTION #3

HIGH EFFICIENCY RECESSED FLUORESCENT TROFFERS (NON-PLANAR LENS)

Open Office Areas—

Fluorescent troffer with high efficiency can reduce spacing criteria while still providing high angles of light distribution on surfaces. This system may be used with dimming ballasts and controls that allow individual customization of light levels in enclosed offices and zoning controls for groups, daylight harvesting. Open office areas would be controlled by zones, manually accessible by users.

The high efficiency troffer solution is affected by ceiling height and architecture of the space. With limited plenum space, this option would be a challenge to integrate with other building systems. All spaces would require automatic shutoff by relay control system. For spaces with daylight access, photo sensor control would be required.

Private Office Areas—

Open offices would use the same lighting concept as open office areas. All spaces would require automatic shutoff by either occupancy sensor or relay control system. For spaces with daylight access, photo sensor control would be required.

Non-Office Areas—

The interior lighting specification for non-office areas would vary through the specific needs of the space. Other luminaire types must be added as needed to achieve proper lighting quality criteria including but not limited to downlights, wall washers, wall sconces, etc. Lighting must comply with IESNA quality criteria as specified in DG-18 and must also comply with the energy savings objective listed below. All spaces would require automatic shutoff by either occupancy sensor or relay control system. For spaces with daylight access, photo sensor control would be required.
