Data Type: 
Constrained List
Unit of Measure: 
Commercial, Residential, Multifamily
List Options Option Definition Unit of Measure
Adjusted Data value has been adjusted by some procedure None
API transfer The value was transferred via a web services or other software connection directly from another software program None
Calculated The data is calculated None
Calibrated The data has been calibrated to improve accuracy None
Confirmed The accuracy of this data was confirmed by an appropriate entity. None
Deemed Deemed savings for an energy improvement that have been pre-determined, based on historical measured experience or based on standardized calculations. Deemed savings are a type of isolated savings estimate. The advantage of deemed savings is their simplicity and standardization of savings estimates. Disadvantages include inaccuracy, if building-specific conditions vary significantly from the values used in the deemed savings estimate. None
Default Defaulted None
Direct input upload The value was entered manually by a user, either through direct typing or spreadsheet upload [this is default] None
eGRID Emissions & Generation Resource Integrated Database. A comprehensive source of data from US EPA's Clean Air Markets Division on the environmental characteristics of almost all electric power generated in the United States. None
Estimated The data point is an estimation of the actual value or condition. None
Extrapolated Data value was estimated using extrapolation None
Historical analysis Data value was replaced by a machine computed value based on analysis of historical data using the same type of measurement None
Integrated Calculation based on whole-building system interactions None
Interpolated Data value was estimated using interpolation None
Isolated Calculations based on single measures without interactive effects None
Measured The value was ascertained using a device. None
Modeled Data value was calculated using a model None
None None None
Normalized for weather Revised to reflect average weather conditions None
Not applicable Not applicable None
Observed The data was noted as a fact through visual observation. None
Other Other None
Rated Data value is from manufacturer rating None
Temporary A temporary value that will be updated later None
Tested Data value was determined using a test procedure None
Unknown Unknown None
