Statewide Electricity and Demand Capacity Savings from the Implementation of IECC Code in Texas: Analysis for Single-Family Residences
MetadataShow full item record
This paper presents estimates of the statewide electricity and electric demand savings achieved from the adoption of the International Energy Conservation Code (IECC) for single-family residences in Texas and includes the corresponding increase in construction costs over the eight-year period from 2002 through 2009. Using the Energy Systems Laboratory's International Code Compliance Calculator (IC3) simulation tool, the annual statewide electricity savings in 2009 are estimated to be $161 million. The statewide peak electric demand reductions in 2009 are estimated to be 694 MW for the summer and 766 MW for the winter periods. Since 2002, the cumulative statewide electricity and electric demand savings over the eight year period from 2002 to 2009 are $1,803 million ($776 million from electricity savings and $1,027 million from electric demand savings) while the total increased costs are estimated to be $670 million.
