EMIS (Energy Management Information System) Cost and Benefits Calculator

1. Enter Area of Building

Enter your building’s floor area to estimate your Net Energy Cost Savings after the implementation and active use of an EMIS platform over a two-year period:

Floor area of building

2. Enter Building's Energy Use

Enter your building’s annual energy use – electricity and/or natural gas – to estimate the Total Energy Use Intensity (TEUI):

Annual Energy Use
Electricty
Natural Gas

3. Enter Annual Expediture

Enter your building’s annual energy expenditure – energy and natural gas combined – to estimate the projected energy expenditure reduction, Total Energy Use Intensity (TEUI) reduction, and CO2 Emission reduction:

Annual Energy Expediture

Median Energy Cost Savings [1] [2] [3]

after two years of EMIS installation

Estimated Net Energy Cost Savings [1] [2] [3]

Total Energy Use Intensity (TEUI)

in kWh/Square-Meter/Year:

Projected Energy Expenditure Reduction [4]

after two years of EMIS installation

Projected Total Energy Use Intensity (TEUI) Reduction [5]

in kWh/Square-Meter/Year after two years of EMIS installation

Projected Total CO2 Emission Reduction [6]

in Metric Tons of CO2 after two years of EMIS installation

Explanations and Disclaimer

  1. These are estimates only! While the calculator provides estimated savings and projections, a formal quote using additional information is necessary when more accurate numbers are required.
  2. Because the study analyzed building portfolios with large gross floor area distribution, the calculator provides more realistic numbers in buildings between 250,000 sq ft and 1,000,000 sq ft. Below 250,000 sq ft, minimum charges apply, while above 1 million sq ft, economies of scale apply.
  3. The primary source in the design of this calculator is the comprehensive report explaining the results of the Smart Energy Analytics Campaign prepared by the Building Technology & Urban Systems Division at the Lawrence Berkeley National Laboratory.
  4. The projected energy expenditure reduction is based solely on the annual energy expenditure and the estimated net energy cost savings and assumes the same percentage reduction on all energy sources. It also assumes no other changes in the building’s energy consumption year-over-year.
  5. The projected Total Energy Use Intensity (TEUI) reduction is based solely on the projected energy expenditure reduction. Differences in property types are not considered, and a more detailed study on source and site energy use is required to further validate these projections. Refer to the Energy Star Portfolio Manager Program resources on Energy Use Intensity for more information.
  6. The projected total CO2 emission reduction is based solely on the projected energy use reduction. Estimated CO2 emissions from both energy sources, electricity and natural gas, are derived from the US Environmental Protection Agency (EPA)’s Greenhouse Gas Equivalencies Calculator and emissions factors in the Calculations and References page. These resources explicitly declare that “these estimates are approximate and intended for communication purposes. They should not be used for emission inventories, formal carbon footprints, or formal emissions analysis.”
