What is LED Lighting?
Light-Emitting Diodes (LEDs) are a long lasting and compact type of light source that uses efficient lighting technology to emit light in a specific direction, reducing the need for reflectors and diffusers while generating very little heat (waste). LED lighting upgrades are a low-cost, high impact opportunity to improve the performance of a building’s lighting system, reduce energy use, enhance occupant comfort, and save money.
Fig 1. Upgrading to more efficient fixtures and installing advanced controls can reduce lighting electricity use by as much as 75%. The diagram below shows a general breakdown of savings, however specific project savings will vary depending on the scope of work and baseline conditions. (Source: BE-Ex analysis, 2017.)
How to Implement
Lighting upgrades can vary considerably in complexity and cost. Understanding the process, players, and goals at the beginning of a retrofit can make the project easier and more successful. Download the full tech primer to learn more about each of the following steps:
A. Upgrade Lamps and Fixtures to incorporate higher efficiency LED alternatives in existing spaces for significant savings
B. Install Advanced Controls and Sensors to ensures functionality and integration of the retrofit through options including real-time scheduling, occupancy and daylight response, task-tuning and color-tuning
C. Incorporate Daylighting control systems to save energy by reducing the level of electric lighting in response to available daylight
D. Incorporate Interior Design by planning smart interior layouts with low cost, passive design solutions can improve energy savings and enhance occupant comfort
Cost and Benefits
Cost and benefits of a LED lighting retrofit will vary depending on your building’s baseline systems and conditions. Typically, buildings can expect to see the following results:
Greenhouse Gas (GHG) Savings
An LED lighting retrofit can greatly reduce lighting related GHG emissions
Tenant Experience Improvement
LED lighting has excellent lighting characteristics, offering a broad range of colors and color rendering capability that can positively influence occupant comfort and satisfaction.
LED lighting uses significantly less energy than incandescent or florescent bulbs, resulting in dramatic utility savings.
LED lighting retrofits requires a relatively low capital investment, although costs can vary greatly depending on
project scope, degree of disruption, and market forces.
LED lights require a low level of maintenance, have a long lifespan, and are easy to dispose of because they do not
contain any of the hazardous heavy metals found in fluorescent lamps.
