Cutting Energy Waste from Commercial Buildings Just Got a Little Easier

Anyone who has ever tried to lose weight knows that it’s hard to do without regularly stepping on the scale. That little instrument doesn’t lie—it tells us if we weigh more or less than we’d like to. It tells us whether our impressive showing at the gym last week was enough to counteract the effects of Saturday night’s four-course meal. And in some cases, a big drop or gain can indicate when something in our body is not working properly.

But did you know that every month, more than 300,000 commercial buildings also step on a scale to make sure that they are in good shape, energy-wise? Before you start picturing a scale the size of a football field, I’ll tell you that this is a virtual scale, available from ENERGY STAR through our online Portfolio Manager tool. Through Portfolio Manager, any building can measure and track its energy use, greenhouse gas emissions, and water use in a secure online account–for free.

Nearly 40 percent of the commercial building space in the country is currently “stepping on the scale” every month through Portfolio Manager. That’s great news because although commercial buildings use about 18 percent of our nation’s energy, and contribute about 18 percent of our greenhouse gas emissions, they don’t have to. On average, about 30 percent of this energy is wasted! And here’s more good news: A recent study of buildings that consistently used Portfolio Manager over a three-year period showed that they cut their energy use by an average of seven percent (or 2.4 percent per year)!

So let’s get more buildings on the scale, and let’s do what we can to help them save energy and trim down their energy “waste”-lines! Here are a few things you can do to help:

  1. Approach leaders at your workplace, your children’s school, your congregation, your favorite stores, and any other buildings in your community. Suggest that they start stepping on the scale and managing their energy use with help from ENERGY STAR. Send them to to learn more.
  2. Bring your green to work! The same simple steps you take at home to save energy can make a big difference in buildings, too. Turn off lights in empty rooms, shut down your computer at the end of the day, and use blinds to block the hot summer sun. Find more tips, plus fun interactive games and quizzes here, on the ENERGY STAR website.
  3. Set a goal to encourage one building in your community to earn EPA’s ENERGY STAR certification. Yup, just like a refrigerator, buildings can also earn the ENERGY STAR if they are among the most energy efficient in the country! Learn more here.

And did we mention that we just launched a complete upgrade to Portfolio Manager? Now it’s easier than ever to use, with new wizards, reports, graphs, and sharing features. With President Obama calling for a 50 percent cut in the amount of energy that commercial buildings waste, there is no better time to encourage the buildings in your community to take Portfolio Manager for a test drive at Who knows how much energy and money you may help them save?

    Having businesses and local organizations steps on the scale to measure their energy output is a great concept. If every player starts doing something like this it can really make a change in the environment for the better. Still one of the major contributing factors is energy that is used on Air Conditioners and heating systems so to prevent energy waste having a Energy Star Unit is very important. Also having someone that properly installs them can be beneficial.
