Zero Code Plug-in Fact Sheet
Residential and commercial buildings are the single-largest energy-consuming sector of the U.S. economy, representing approximately 39% of U.S. total energy consumption and 74% of its electricity use, which makes buildings responsible for 35% of energy-related emissions. DOE provides technical assistance supporting cost-effective increases in energy efficiency and performance of homes and commercial buildings through building energy codes.
Development of National New Construction Weighting Factors for the Commercial Building Prototype Analyses (2008-2022)
The U.S. Department of Energy (DOE) tasked Pacific Northwest National Laboratory (PNNL) with updating commercial building1 construction weights for the purpose of estimating national and state-by-state energy savings impacts of changes made to various commercial energy codes and standards. For commercial building analyses, PNNL typically uses a suite of 16 prototype buildings simulated in the 19 ASHRAE climate zones with 16 of them present in the United States. The 2008-2022 commercial building weighting factors were derived using the same approach employed to develop the 2003-2018 set (Lei et al, 2020).
ANSI/ASHRAE/IES Standard 90.1-2022 Performance Rating Method Reference Manual
This document is intended to be a reference manual for the Appendix G Performance Rating Method (PRM) of ANSI/ASHRAE/IES Standard 90.1-2022 (Standard 90.1-2022). The PRM can be used to demonstrate compliance with the standard and to rate the energy efficiency of commercial and high-rise residential buildings with designs that exceed the requirements of Standard 90.1.
Commercial Cost Effective Methodology 2024
This document lays out the Department of Energy’s (DOE’s) methodology for evaluating the cost-effectiveness of energy code and standard1 proposals and editions. The evaluation is applied to new provisions or editions of ANSI/ASHRAE/IES2 Standard 90.1 and the International Energy Conservation Code. The methodology follows standard lifecycle cost (LCC) economic analysis procedures.
90.1 Appendix G PBM - All Buildings - ASHRAE 90.1-2022 Proposed
These prototypes are used to calculate Building Performance Factors (BPFs) for use with the Performance Rating Method of ASHRAE Standard 90.1-2016 though 2022. These prototypes are used to implement the new approach to calculating BPFs that follow the Appendix G baseline rules and include adjustments to the prototype models made after a specific code has been published. Those BPFs are therefore different than those published in ASHRAE Standard 90.1 2016-2022. This new approach is discussed in more detail in the PNNL Technical Support Document titled, Commercial Building Prototypes Based on ANSI/ASHRAE/IES Standard 90.1-2019 Appendix G PRM.
