Anyone who thinks energy efficiency isn't worth the cost should study the example of the U.S. Postal Service.

The federal agency figured it would cut energy bills at a New York City processing center by $30,000 per year. Instead, the new green roof and other energy-saving measures whacked off a whopping $1 million.

Installing the green roof, changing 1,600 windows and other upgrades slashed energy consumption 40% per month. The crown jewel of the project, the green roof, covers nearly 2.5 acres. Nearly 90% of the original roof was recycled and used during the remodeling. The new roof is project to last 50 years, twice as long as the original covering.


The New York City building is pursuing LEED certification, following post offices in Denver, CO. and Southampton, N.Y., and processing centers in Greenville, S.C., and Troy, MI.

As a result, the Postal Service is more than two thirds of the way to achieving its goal of 30% energy reduction by 2015.


The San Joaquin Valley Clean Energy Organization is a nonprofit dedicated to improving our region's quality of life by increasing its production and use of clean and alternative energy. The SJVCEO works with cities and counties and public and private organizations to demonstrate the benefits of energy efficiency and renewable energy throughout the eight-county region of the San Joaquin Valley
