The Challenge

South Shore Bank began working with Prism Energy Services in order to upgrade its outdated lighting systems. The bank’s board room, in particular, required better light levels. The challenge was coming up with cost-effective interior and exterior lighting solutions to improve the energy efficiency of the facility at a project cost that made financial sense.

The Prism Solution

Prism Energy Services conducted a comprehensive site evaluation and identified and replaced over 700 interior and exterior lighting fixtures to new energy efficient LEDs. The majority of the pre-existing fixtures were fluorescents, with the exception of incandescent lamps in the board room. The parking lot lights also received a significant upgrade from metal halide to LED.
The new LED lights will improve the color rendering index of the facility, brightening all areas of the bank, while also improving visibility and significantly reducing shadows on the walls and ceilings. Prism also installed sensors and controls throughout the facility. Motion sensors were installed on a majority of the lighting fixtures, which help save energy by automatically turning off lights in unoccupied areas. Furthermore, vending misers were installed on the bank’s vending machines, which automatically power down the machines when not in use.

The Bottom Line

The pre-existing lights were consuming 187,559 kWh per year. After the new LEDs were installed, the energy consumption dropped to 55,574 kWh, an energy reduction of 70 percent. This significant decrease in energy consumption will help South Shore Bank save $19,005 a year. Prism also helped South Shore Bank receive $53,887 in utility incentives, covering about 34 percent of the total installation cost.
