General Area Type Case Study:

Correctional Facilities

Lighting upgrades in the open spaces and hallways of correctional facilities, can improve the lighting environment and when combined with controls provide 30% of the building’s potential energy savings! The following chart shows the savings potential of more area types by combining both lighting and sensor upgrades:

Private Office

A common application representing 5-10% of the total building savings. Controls and lighting upgrades provide an improved working environment and convenience.

Open Office Space

Lighting upgrades improve the working environment, however an often overlooked application for controls typically provides 30% of the building’s potential savings!

Meeting Rooms

An area type with fluctuating usage and often unoccupied with the lights left on. Popular application for Controls and Lighting providing 5% of the total building’s savings.

Hallways

With long run hours, Lighting upgrades are common. However, this is also an ideal application for Controls providing, 15-25% of the building’s potential savings! Sensors also add convenience and an element of security.

Storage

The infrequent use makes this an ideal application for Controls, providing 10% of the building’s potential savings. A common retrofit is the replacement of Incandescent to LED or Fluorescent and keeping the annual usage to a minimum with the sensors, means these lights will almost never need maintenance.

Restrooms

Sometimes a difficult application due to the partitioned stalls. Properly applied dual technology sensors, however, resolve this issue, allowing for 10-20% of the building’s potentials savings. Additional savings can be obtained by controlling the exhaust fans as well.

Cells

Although cells represent half of the lighting load in a correctional facility, they only provide 12-25% of building’s potential savings. Lighting upgrades can improve the environment, while being an opportunity for daylight harvesting.
