The purpose of lighting at Penn State is to provide adequate illumination to support the University mission, with particular attention to safety and security, energy, sustainability, maintainability, architectural compatibility, and human visual performance/physiology.

General

The design shall follow PSU AD64 Energy Conservation Policy.

The design and commissioning shall follow the Pennsylvania State University Lighting Design & Commissioning Matrix. Areas not specifically addressed in the matrix shall be coordinated with PSU Engineering Services Electrical Group.

Lighting Survey

Provide an interior or exterior lighting survey where environmental changes or luminaire changes significantly alter the lit environment.  Significant changes include:

1. Exterior: Rerouting of pedestrian or vehicular traffic such as new/altered sidewalks, midblock crossings, streets.
2. Exterior: Addition of light-blocking environmental changes such as structures and landscape.
3. Interior and Exterior: Emergency luminaires added, removed or altered as part of both new construction and renovation. (A lamp replacement of same wattage and lamp source does not warrant a Lighting Survey).

A Lighting Survey may not be necessary where the environmental change includes a new lighting design as part of the project. In this case, photometric calculations may be sufficient.

Perform the lighting survey with NIST-calibrated illuminance meter, calibrated within 1-year. Submit legible report with brief narrative, including illuminance survey results, and documentation of meter calibration. Elements of the lighting survey shall include: documentation of existing illuminance levels on plan; summary of statistics such as illumination averages, maximums, minimums and uniformity ratios; comparison of measurements with IES recommendations and/or code requirements.

Confirm specific lighting survey requirements for the project with Engineering Services Electrical Group. Obtain a measurement and report template from Engineering Services Electrical Group for verifying means of egress illumination.

Historical Luminaires

 Coordinate applications with Engineering Services Electrical Group and University Architect. In general, historic architecture – particularly those landmarks with original luminaires – require the luminaires to maintain the existing or original character of the design. The historical luminaires may be converted to LED and restored by a qualified historic lighting restoration manufacturer, as discussed with Engineering Services Electrical Group and the University Architect.

Design shall follow PSU AD64 Energy Conservation Policy.

The design and commissioning shall follow the Pennsylvania State University Lighting Design & Commissioning Matrix. Areas not specifically addressed in the matrix shall be coordinated with PSU Engineering Services Electrical Group.

Practical Considerations

To promote long-term successful lighting installations:

1. Simplify / optimize the number of control zones and luminaire types in a space.
2. Consider the future now: how will the specified luminaire likely be replaced in the future? Can the design team optimize the solution now so it is more likely that the replacement luminaire will be architecturally compatible?
3. Consider the aesthetic impact of failed luminaires. For example, if the lighting concept involves continuous runs of linear lights or the rhythm of a series of luminaires, how disruptive will the installation appear if 5 to 10% of the luminaires have failed?
4. Consider the pros and cons of remote drivers for the luminaire’s end of life. How will a replacement luminaire be powered if the manufacturer is obsolete?
5. Minimize luminaires in hard ceilings. Avoid flangeless mounting.
6. Avoid luminaires that are highly-integrated to other elements (such as hand rails, mullions, ceiling elements).
7. Consider luminaires with a minimum aperture or lens size of 3 or 4 inches.
