Texas Emissions and Energy Calculator (eCALC): Documentation of Analysis Methods, Report to the TCEQ
MetadataShow full item record
This report provides documentation about the Energy Systems Laboratory’s Emissions and Energy Calculator (eCALC), including information about the web structure, new building models, and community projects. In each of the sections a description of the basic user input is provided, and a description of the analysis that eCALC performs once the use submits a project for analysis. This report also provides a brief summary of the literature reviews for the analysis methods that were developed to document the uncertainty reported in the literature, including: F-Chart, PV F-Chart, ASHRAE’s Inverse Model Toolkit (IMT), Cool Roofs, and the DOE-2 program. This report also provides a description of the methods used to assemble actual weather data files for 1999 through 2003 for use in eCALC.
DescriptionIn the Fall of 2003, the Energy Systems Laboratory (ESL) formed a partnership with the Texas Commission for Environmental Quality (TCEQ), and the USEPA, to enhance the Emissions Reduction Calculator. Since then, the Laboratory has worked closely with the TCEQ, using funding provided by the USEPA, to enhance the calculator. This section of the report provides additional details about the webbased structure of the Laboratory’s web-based calculator, including a complete description of each of the major modules contained in the calculator.
