Validation of the International Code Compliant Calculator (IC3) Using the RESNET Verification Procedures (No. 07-003)

Abstract

This report presents results from the testing and validation of the Energy System's Laboratory's web-based software tool--International Code Compliance Calculator (IC3), v3.3, using the Residential Energy Services Network (RESNET) verification procedures - RESNET Publication No. 07-003. The IC3 software is a web-based tool to demonstrate compliance of single-family residences with the Texas Building Energy Performance Standards (TBEPS) (i.e., the 2000 International Energy Conservation Code (IECC) with the 2001 Supplement and 2006 National Appliance Energy Conservation Act (NAECA) revisions). The user-interface of IC3 was designed to ensure simple and quick input through reduced user input fields and present a simplified output by only reporting the code-compliance as a percent above or below code for locations in Texas.
