Tennessee Residential Energy Code Field Study
Document Number: PNNL-31125 | Document Type: Field Study, State-specific | Publication Date:

A research project in the state of Tennessee identified opportunities to reduce homeowner utility bills in residential single-family new construction by increasing compliance with the state energy code.  The study was initiated in September 2017 and continued through July 2018.  Analysis of the data has led to a better understanding of the energy features present in homes and indicates over $2.5 million in potential annual savings to Tennessee homeowners that could result from increased code compliance.

Florida Building Code, Energy Conservation, 2020 vs. 2018 International Energy Conservation Code Residential Stringency Analysis
Document Number: FSEC-CR- 2102-20 | Document Type: State-specific | Publication Date:

This project was initiated to review residential provisions of the Florida Building Code, Energy Conservation, 7th Edition (2020) (FBC-EC) in order to make a determination if it meets or exceeds the 2018 International Energy Conservation Code (IECC).

This project’s code stringency evaluation activities included:

  • Reviewing residential provisions of the 2020 FBC-EC and comparing them with residential provisions of the 2018 IECC
  • Listing impactful code differences by Mandatory, Prescriptive, Performance and Energy Rating Index categories and providing the anticipated stringency impact for each
  • Using EnergyGauge® USA energy modeling software to compare 2018 IECC and 2020 FBC-EC Prescriptive and Performance compliance method stringencies.
Quantitative and Economic Analysis of the 2020 Florida Building Energy Code
Document Number: FSEC-CR-2089-20 | Document Type: State-specific | Publication Date:

This project was initiated because of the state of Florida desire to review provisions of its proposed 7th Edition (2020) Florida Energy Code (FEC) for commercial buildings in order to make a determination if it meets or performs better than ASHRAE 90.1-2016 code. For this purpose the proposed code modifications were reviewed and quantitatively analyzed.
