2023 National Energy Codes Conference (NECC) agenda; updated with new files as revisions are made. 

Total System Performance Ratio (TSPR) is a metric for evaluating overall system efficiency instead of individual component efficiency, a solution that could also eventually facilitate the transition to a 100% performance-based code structure. TSPR is a ratio that compares the annual heating and cooling load of a building to the annual energy consumed by the building's HVAC system. This technical documentation provides background on the TSPR and support for the mechanical performance factors that are developed each 90.1 edition cycle to be used in the calculation. The current factors are developed for the 2022 edition of 90.1 in combination with addendum AG.

This report summarizes the research effort conducted by Pacific Northwest National Laboratory (PNNL), National Renewable Energy Laboratory (NREL), and Lawrence Berkeley National Laboratory (LBNL) to develop a standardized methodology to quantitatively assess how energy-efficiency measures affect building thermal resilience. The study outlines a proposed standardized methodology and set of metrics, reports initial findings resulting from the efficiency resilience valuation effort, and identifies areas of need for continued research and analysis.

This document presents a methodology for assessing baseline energy efficiency in new single-family residential buildings and quantifying related savings potential.

Beginning in 2014, the U.S. Department Energy (DOE) funded a series of multi-year residential energy code field studies to explore energy savings opportunities from enhanced code compliance. This report presents the final results across the three phases to assess whether the education and training activities successfully improved code compliance to achieve significant changes in energy use.

The purpose of this report is to document findings and final results from the Texas field study, including a summary of key trends observed in the field, their impact on energy efficiency, and whether the selected education and training activities resulted in a measurable change in statewide energy use.

The purpose of this report is to document findings and final results from the Pennsylvania field study, including a summary of key trends observed in the field, their impact on energy efficiency, and whether the selected education and training activities resulted in a measurable change in statewide energy use.

The purpose of this report is to document findings and final results from the North Carolina field study, including a summary of key trends observed in the field, their impact on energy efficiency, and whether the selected education and training activities resulted in a measurable change in statewide energy use.

The purpose of this report is to document findings and final results from the Maryland field study, including a summary of key trends observed in the field, their impact on energy efficiency, and whether the selected education and training activities resulted in a measurable change in statewide energy use.

The purpose of this report is to document findings and final results from the Kentucky field study, including a summary of key trends observed in the field, their impact on energy efficiency, and whether the selected education and training activities resulted in a measurable change in statewide energy use.

The purpose of this report is to document findings and final results from the Georgia field study, including a summary of key trends observed in the field, their impact on energy efficiency, and whether the selected education and training activities resulted in a measurable change in statewide energy use.

The purpose of this report is to document findings and final results from the Alabama field study, including a summary of key trends observed in the field, their impact on energy efficiency, and whether the selected education and training activities resulted in a measurable change in statewide energy use.

This report provides an assessment as to whether new buildings constructed to the commercial energy efficiency provisions of the 2021 IECC would save energy and energy costs as compared to the 2018 IECC. The Commercial Energy Efficiency chapter in the 2021 IECC allows users to either follow the provisions in the IECC or use Standard 90.1-2019 as an alternative compliance path. As such, PNNL also compared the energy performance of the 2021 IECC with the corresponding Standard 90.1-2019 to help states and local jurisdictions make informed decisions regarding model code adoption.
