About this file

This is a Design Criteria and Facility Standards Manual issued by the University of Maryland, College Park, establishing standards for exterior lighting fixtures on campus facilities, effective January 1, 2020. The manual applies to all new building designs and renovation work involving the installation or relocation of lighting fixtures, provided the lighting work comprises at least 50 percent of the lighting within the renovated space. UMD's standard for outdoor pole lights specifies 5-inch straight round poles with 30-foot mounting heights, with the Altitude 3 Fixture by Kim Lighting designated as the basis of design. Exterior LED fixtures must meet minimum L70 lumen maintenance at 50,000 hours per IES LM-80 standards, with color temperature of 3000K or as specified by project lighting study, Color Rendition Index of 70 or higher, and a B.U.G. rating of B5-U0-G3. The manual requires compliance with IEC 2015, ASHRAE 90.1-2013, IBC 2015, IRC 2015, IECC 2015, IGCC 2015, and IESNA standards.

Lighting installation requirements mandate point-by-point photometric calculations demonstrating compliance with IES recommendations and University requirements, with light levels measured using full spectrum light meters or at 90 percent of IESNA standards using photopic light meters. Outdoor lighting for sidewalks, parking lots, and streets must be controlled via central photocell for on/off activation with a 7-day, 24-hour time clock and Hand-Off-Auto switch mounted in non-public areas. All fixture mounting, pole bonding, and grounding must comply with the National Electrical Code, and junction boxes must be labeled with circuit number, power panel number, and room number for panel location. Any deviations or exceptions to these requirements require prior written approval from the Director of the Operations and Maintenance Department in Facilities Management Electrical Systems Section.

Design Criteria/Facility Standards Manual Page 1 University of Maryland, College Park

Description:

The purpose of the section is to highlight the current applicable UMD Design Standards for the design, selection and installation lighting fixtures located on the exterior of buildings, the project site and, the surrounding campus arena.

Related Sections:

• 26 51 00 Lighting-Interior

Effective Date:

January 1, 2020

Applicable Standards:

• IEC 2015 – ASHRAE 90.1 – 2013

• IBC 2015 w/ the Department of Housing and Community Development (DHCD) modifications (Ref: COMAR

05.02.07)

• IRC 2015 w/ the DHCD modifications

• IECC 2015 & IGCC 2015

• Illuminating Engineering Society of North America (IESNA) Standards

General Requirements:

The application of this section applies to all interior and exterior lighting in “new building” designs. This section also applies to “renovation work” within existing buildings--if the installation of new light fixtures, or the relocation of existing light fixtures is a part of the renovation, and the lighting work involves at least 50% of the lighting within the renovated space. Any deviation or exception to the requirements of this section requires the prior written approval of the Director of the Operations and Maintenance (O&M) Department in Facilities Management Electrical Systems Section, as well as notification to the Electrical Systems Section within O&M.

Light Fixture Recommendations/Guidelines

• Outdoor

• UMD standard for outdoor pole lights shall be a 5” straight round pole with 30’ mounting height. Basis of design; Altitude 3 Fixture by Kim Lighting. Base plate to match application (i.e. New Build or Retrofit).

• Lamp Specifications

• Exterior LED fixtures shall have minimum L70 lumen maintenance at 50,000 hours in accordance with IES

LM-80

• Exterior lighting shall minimize glare, uplight, and light trespass in accordance with IES recommendations

• Color temperature shall be 3000K or as specified by project lighting study.

• Color Rendition Index (CRI) of 70 or higher

• B.U.G. RATING: B5-U0-G3

• 387 Watts

• 44k Lumens

• Distribution: Type 5 Square Medium

Lighting Installation/Performance Guidelines

• Lighting Levels

• Light levels shall be as specified by the Illuminating Engineering Society of North America (IESNA) handbook (latest edition), unless modified below.

• Light levels shall be measured by “full spectrum” light meters, or at a level of 90% of IESNA Standards using “photopic” light meters.

• Provide point-by-point photometric calculations for exterior lighting systems demonstrating compliance with IES recommendations and University requirements

Design Criteria/Facility Standards Manual Page 2 University of Maryland, College Park

• Controls

• The outdoor lighting for sidewalks, parking lots and street shall be controlled via central photocell to turn the lights on, and a 7 day/24 hour time clock to turn the lights off, and a “Hand-Off-Auto” (HOA) switch to operate the lights manually. The HOA switch shall be mounted in an area not accessible to the general public.

• Wiring Configuration

• Support wire systems as required by the NEC.

• Fixture Mounting

• Lighting fixtures shall be supported in accordance with code.

• Lighting poles and metal support structures shall be bonded and grounded in accordance with NEC

Article 250.

• Labels

• Junction boxes utilized for power distribution, shall be labeled on the cover plate with the following information.

• Circuit Number (feeding the light fixture)
