The Energy Planning Analysis Tool can be used to support the US natural gas industry in positioning direct gas use as option for energy efficiency programs, building energy codes, proposed EPA Clean Power Plan, or in other areas of public policy.

The tool calculates source energy consumption and selected air emissions including Greenhouse Gas (GHG) emissions associated with annual site energy consumption by purchased fuel type of electric and natural gas applications defined by user-selectable and default inputs. It shows the potential energy and cost benefits of replacing or buying more energy efficient equipment, typically using natural gas as fuel.
