The purpose of this analysis is to examine the cost-effectiveness of the 2016 edition of ANSI/ASHRAE/IES2 Standard 90.1(ANSI/ASHRAE/IES 2016). PNNL analyzed the cost-effectiveness of changes in Standard 90.1-2016, compared to the previous 90.1-2013 edition, as applied in commercial buildings across the United States.  

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.

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.

Companion spreadsheet to the National Cost Effectiveness of Standard 90.1-2016 report.

This report provides an assessment as to whether new buildings constructed to the commercial energy efficiency provisions of the 2018 IECC would save energy and energy costs as compared to the 2015 IECC. The Commercial Energy Efficiency chapter in the 2018 IECC allows users to either follow the provisions in the IECC or use Standard 90.1-2016 as an alternative compliance path. PNNL also compared the energy performance of the 2018 IECC with the corresponding Standard 90.1-2016 to help states and local jurisdictions make informed decisions regarding model code adoption.
