For many building owners saving energy in facilities has been a big business strategy in recent years, since saving energy ultimately results in reduced overhead expenses. But what about the energy consumed in parking garages?

The U.S. Dept. of Energy,, Washington, D.C., recently announced its support of the LEEP (Lighting Energy Efficiency in Parking) Campaign, which aims to improve the energy efficiency of lighting in parking lots and garages.

The campaign already has more than 100 U.S. businesses and organizations participating and planning to install energy-efficient lighting in parking lots and garages. Together, this will amount to more than 270 million-sq.ft. of parking space with energy-efficient lighting, which will cut energy use by up to 90%.

According to the U.S. Dept. of Energy, building owners spend more than $6 billion to light parking lots and garages, and a significant portion of this could be saved with energy-efficient lighting.

What does this look like for building owners? Many participates have upgraded facilities to include high-efficiency metal halide, fluorescent, and LED (light-emitting diode) solutions that will last three times longer than previous lighting. What’s more, owners can also use controls to be able to reduce energy use when parking facilities are not in use.

What was once considered a big step forward in building automation and lighting controls is now extending to parking garages. It will be interesting to watch as this trend continues to grow, and to see how corporate owners begin to adopt the technology.
