Description

• Site lighting includes all lighting across the campus.  Exterior lighting is provided at entry ways, court yards, walkways, grassy areas, property perimeter, parking lots and uplighting for signage and planting, etc. Site lighting types may be poles, surface mounted fixtures on building facades, fencing, signage or installed as bollards or landscape mounted. 
• New lighting should meet minimum lumen levels to provide adequate lighting for path illumination at night.  LED fixtures are required for all new lighting to improve energy efficiency and replace older, fluorescent and metal halide lighting fixtures.  Preference is for durable fixtures which focus on ease of maintenance.
• Exterior site lighting serves to enhance safety and security by illuminating outdoor areas to deter crime, improve visibility for surveillance, and guide occupants safely. Effective design involves selecting appropriate lighting fixtures, positioning them strategically to eliminate shadows and blind spots, ensuring even illumination across the property, using energy-efficient and durable lighting technology, and incorporating motion sensors or timers for adaptive lighting control.

Baseline

• Exterior lighting design should encourage street life and integrate NYCHA grounds with the surrounding community. Designers should limit the use of wall packs fixtures on residential buildings. Light fixtures should be as energy efficient as possible, promote ease of maintenance, and reduce light pollution.
• Exterior lighting is required on pedestrian paths, near seating, play and athletic areas, in parking lots and along vehicular circulation paths, at building entrances, and on building facades.
• EGC requirements:
  • Minimum 40 lumens per watt
  • Recessed light fixtures must be Insulation Contact Air-Tight (ICAT) models with ENERGY STAR LED.
  • Exterior lights fixtures must be ENERGY STAR LED, Dark-sky-friendly, and must include motion sensor,
  • Common-area lights must be LED and must include an occupancy sensor or bi-level control.
• Exterior lighting controls shall comply with the requirements of the 2020 NYC Energy Conservation Code:
  • Lights shall be automatically turned off when daylight is present and satisfies the lighting needs
  • Lighting shall be controlled so that the total wattage lighting is automatically reduced by not less than 50 % by selectively switching off or dimming luminaires at one of the following times:
    • From no later than midnight (12a.m.) to no earlier than 6 a.m.
    • During any time where activity has not been detected for 15 minutes or more.
• Exterior lighting shall be controlled by time-switch and should comply with the following:
  • A clock shall be capable of being programmed for not fewer than 7 days.
  • Shall be capable of being set for seven different day types per week.
  • Shall incorporate an automatic holiday setback feature.
  • Shall have program backup capabilities that prevent the loss of program and time settings for a period of not less than 10 hours if power is interrupted.
• Luminaires serving outdoor parking areas and a mounting height of 24 feet (7.3 m) or less above the ground shall be controlled to automatically reduce the power of each luminaire by a minimum of 50 % when no activity has been detected in the area for a time of no longer than 15 minutes.
• PACT Partners should evaluate opportunities to improve site access and introduce additional site lighting, to improve overall site security and safety. [PACT]

Stretch

• Where possible new lighting fixtures should contain integrated photovoltaic cells, photosensors, and astronomic time clock control. 
• These photovoltaic fixtures will provide outdoor lighting without the need for substantial electrical supply.
• These photovoltaic fixtures should be located away from buildings and outside of tree coverage to provide maximum available sunlight.
