Lighting Committee

Goal

To develop and coordinate lighting standards for UNB, its surrounding Community and the Environment. To address lighting concerns efficiently and cost effectively, while providing a healthier lighting environment for UNB.

Awareness

  • Lighting is the single largest electrical user in commercial/institutional buildings
  • Energy-efficient lighting is also inexpensive lighting
  • Lighting contributes to electricity consumption both directly, by using electricity to power lights and indirectly, by increasing cooling use

The Lighting Committee has focused on the issues and concerns of lighting from the initial design and proposal stage to the on-going maintenance and stocking of the product. The committee has the following recommendations - improving design strategies, encouraging better communication among the disciplines involved in a building or renovation project. The process does not stop there. Moving forward with the creation of campus lighting standards, where the implementation of a five year plan would stabilize uniformity in an energy-efficient design as well as provide cost effectiveness in purchasing and inventory. The development of a database that would identify the technical specifications and warranty of each light, fixture and ballast for each room of every building on campus, would expedite and reduce costs in the area of electrical maintenance and stocking. The committee has made excellent progress and we look forward to the challenges and growth of this initiative.

Lighting affects the environment in a number of ways including energy usage, the materials used to produce lighting products, and its impact on the nighttime sky. For example, energy-efficient lighting demands less electricity, which reduces polluting power plant emissions. Some materials used in lamps, such as mercury, are toxic to the environment and must be handled carefully. Light shining into the sky causes light pollution.
