Texas Field Study – Phase I Results

Total Potential Savings

Phase I, Data Collection and Analysis, of the Texas Energy Code Field Study has been completed. The Pacific Northwest National Laboratory modeled the results and calculated the potential savings if all new homes were built to the state energy code that went into effect on September 1, 2016. The total savings are shown in the table below.

Annual Savings Potential From Individual Measures

The analysis found that the average efficiency of the 134 homes sampled is above the statewide 2009 energy code in effect at the time of the sampling. Some of the cities in the sample area were operating under more efficient codes. The measure savings in the table below and the cumulative savings above represent the savings from the five measures that the analysis found to have at least a 15% potential savings compared to the 2015 energy code.

Details of the DOE Field Study, including sampling and data collection information for Texas and the other participating states, are available and updates are posted regularly.

The Texas Phase I report is now available.

Phase II

Based on the results of Phase I, SPEER has focused the education and outreach effort in Phase II on improving compliance with the five high potential savings measures.

SPEER created fact sheets on each of the high potential savings measures identified in Phase I. These fact sheets include best practices to comply with the new code requirements and resources for training and education on each measure:

Fact Sheet: Lighting Requirements

Fact Sheet: HVAC System Duct Sealing and Testing

Fact Sheet: Envelope Sealing and Air Leakage

Fact Sheet: Insulation R-value and Installation Quality
