What is the Energy Star Rating? How do I Utilize it?

Monday, November 05, 2012

Calculating the Energy Star Rating of your building provides you with a report that includes the following information:

  • Total Energy Usage
  • Total Energy Spent
  • Carbon Footprint (Greenhouse Gas Emissions)
  • Comparison of energy spent and energy costs with facilities of similar size and use
How do I utilize this information?

Benchmarking your buildings’ energy performance is a key first step to understanding and reducing energy consumption and your carbon footprint. Calculating the Energy Star Rating for your building provides you with a benchmark based on a national survey conducted by the Department of Energy’s Energy Information Administration. This national survey, known as the Commercial Building Energy Consumption Survey (CBECS), is conducted every four years, and gathers data on building characteristics and energy use from thousands of buildings across the United States. A rating of 50 indicates that the building performs better than 50% of all similar buildings nationwide, while a rating of 75 indicates that the building performs better than 75% of all similar buildings nationwide. Buildings rating 75 or greater may qualify for the ENERGY STAR label.

Establishing your building’s energy star rating provides a means of tracking energy saving measures. Energy costs typically account for 21% of the total cost of operating a building, working towards a higher energy star rating will save a substantial amount of money.

OK, how do I get started?

To calculate your building’s energy star rating you merely need to gather the following information:

  • 1 Continuous year of energy bills
  • Basic building information (size, usage, age, etc.)

Find out where your building stacks up to those of similar function and size nationwide. For more information visit the ENERGY STAR website.
