Lighting Design
General
- Refer to the Pennsylvania State University Lighting Design & Commissioning Matrix.
- Refer to Section 26 09 00 Instrumentation and Control for Electrical Systems.
- Consider safety-by-design techniques to minimize safety hazards in operations/maintenance of luminaires throughout the life-cycle. For example: high mounting heights in atria can be problematic. Consider remote mount drivers where fixture mounting heights exceed twenty (20) feet, or access to luminaires is restricted.
- Base bid shall utilize dimmable LED source and controls for all general lighting. Discuss luminaire application with Engineering Services Electrical Group.
- The Illuminating Engineering Society’s Recommended Practices shall be used as a standard for lighting levels. Provide a spreadsheet showing all room names and numbers along with target illumination levels.
- Specify the proper disposal of mercury containing lamps per PSU Policy SY-31 and PCB ballasts per PSU Policy SY-26 for all renovation work.
- Minimize discomfort glare in normally occupied areas. Refer to the latest guidance in WELL, LEED and IES RP-1 concerning luminance thresholds. In regularly occupied spaces, to avoid discomfort glare, luminaires with luminances at higher angles should be less than 8,000 cd/m2 for luminaires normally viewable by occupants. Where the proposed lighting design includes luminaire luminances expected to exceed 8,000 cd/m2 for luminaires normally viewable by occupants, provide engineering justification for review and approval by Engineering Services Electrical Group in design development. Practically, this means linear luminaires with small lens dimensions (e.g. 2-inch or less) should not be specified, or should be specified with precise lens optics and/or baffles to satisfy Engineering Services Electrical Group glare concerns.

All pertinent calculation parameters shall be indicated, highlight highlight where the design is non-IES compliant. Engineering Services Electrical Group will provide direction and variance where deemed adequate. Utilize AGI-32 full calculation mode or similar program, as approved by Engineering Services.
- The Illuminating Engineers Society Lighting Handbook, current edition, including IES recommended practices, shall be used as a standard for lighting levels. Provide a spreadsheet showing all room names and numbers along with target illumination levels. For television studios and classrooms used for TV production, consult Engineering Services for guidelines.
- Refer to 26 00 01 .10 - B Elevator Service and Support for applicable illumination requirements.
- Medium and high bays in shops, lobbies, etc. shall be LED. Drivers must be rated for high temperature environment. Consider remote mount drivers where fixture mounting heights exceed twenty (20) feet, or access to luminaires is restricted. Remote drivers shall be installed per manufacturer’s requirements.
