Envelope Advisor Cost and Benefits Calculator

The following calculator [1][2] is based on the largest dataset generated to date on EMIS costs and benefits as documented by the Smart Energy Analytics Campaign [3] over a 4-year partnership program.


1.Enter Area of Building

Enter the total floor area of your building in square feet or square meters, as selected below.

2.Enter Building's Energy Use

Enter the total annual electricity consumption in kilowatt-hours (kWh) or kilo-British thermal units (kBtu), as selected below.

Enter the total annual natural gas consumption in gigajoules (GJ) or kilo-British thermal units (kBtu), as selected below.

3.Enter Annual Expenditure

Enter the total annual energy expenditure in US dollars (USD).

Explanations and Disclaimer

  1. These are estimates only! While the calculator provides advisor cost, estimated savings and projections, a formal quote using additional information is necessary when more accurate numbers are required. For a project-specific quote, please email us at advisor-quote@armstrongfluidtechnology.com with the relevant project details.
  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 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.
  5. 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.”
