The amount of carbon dioxide equivalent gasses emitted due to the facility's energy consumption.
CO2-eq Emissions Reduction
The CO2-eq is a measure of how much better your facility performs compared to a median building (which is the equivalent of an energy performance rating of 50). It is calculated by comparing the design or target CO2-eq emissions against the CO2-eq emissions for that facility with a rating of 50.

Energy Performance Rating (1-100)
The rating for a facility on a scale of 1-100 relative to similar buildings nationwide using EPA's national energy performance rating. The rating is based on your design project's source energy use, level of business activity, and geographical location.
The rating indicates the percentile rank of the facility once all required data is entered. A 68 rating means that the design ranks in the 68th percentile when compared to similar facilities nationwide. To qualify for the ENERGY STAR, a design must have a rating of 75 or higher.
Note: Users can only select a Target Rating from 50 - 100 for a project, however the estimated energy use for the Design project could receive a rating from 1- 100 depending on how energy efficient it is compared to similar buildings.
Energy Reduction %
The energy reduction is a measure of how much better your facility is intended to perform as compared to a median building (as compared to an EPA energy performance rating of 50). Percent energy reduction is calculated by comparing the design or target energy consumption against the consumption for that of similar facilities with a rating of 50.
IT Energy (Annual)
IT Energy is defined as the total amount of energy required by the server racks, storage silos, and other IT equipment in the Data Center. For the purposes of Target Finder, the Annual IT Energy should be estimated as part of the design, and should be analogous to the equipment IT load that will be supported by the Uninterruptible Power Supply (UPS) (i.e. the load that will be measured at the UPS output once the facility is in operation).
The median represents the 50th percentile of a distribution (i.e. group or sample) of numbers. When the numbers in the group are ranked from smallest to largest, the median is the number in the middle. Half of the numbers in the group fall above the median and half of the numbers fall below the median. It is comparable to a score of 50 on the ENERGY STAR performance scale - where half of the buildings of a given type use more energy than the median and half of the buildings use less energy.
Median Building Column
Median Building column that displays results for the Energy Performance rating, Energy Reduction percent, Source EUI and Total Annual Energy, Site EUI and Total Annual Energy, Total Energy Cost, CO2 Emissions and Reductions.
Site Energy Use Intensity (kBtu/Sq. Ft./yr)
The annual on-site energy intensity estimate for your building design which accounts for all energy consumed at the building location.
Source Energy Use Intensity (kBtu/Sq. Ft./yr)
The annual source energy intensity is calculated for your building design by Target Finder. Source energy is a measure that accounts for the energy consumed on site in addition to the energy consumed during generation and transmission in supplying the energy to your site. EPA's national energy performance rating is calculated using source energy.
Target Rating (Energy Performance Rating)
The target rating is selected from a 50 to 100 scale (representing the percentile of performance). A 75 target would indicate that the energy design intent for the project is in the top quartile (i.e. top 25%) and achieves Designed to Earn the ENERGY STAR.
Target Finder also uses the 1-100 scale to provide a rating for your design project's estimated annual energy as compared to the US commercial building population of similar buildings.
Total Annual Energy Cost ($)
The total annual energy cost is derived from user input or default values in Target Finder. The rate is derived from the DOE-EIA State Average Fuel Rate based on the zip code for your design location.
Total Annual Site Energy (kBtu)
The total estimated annual on-site energy consumption for the building design.
Total Annual Source Energy (kBtu)
The estimated total annual energy consumption for on-site energy and energy consumed during generation and transmission.
