2022 National Energy Codes Conference (NECC)Session Moderators, Speakers, and Bios

2022 National Energy Codes Conference (NECC) agenda; updated with new files as revisions are made. 

The purpose of this analysis is to examine the cost-effectiveness of the 2019 edition of ANSI/ASHRAE/IES2 Standard 90.1(ANSI/ASHRAE/IES 2019). PNNL analyzed the cost-effectiveness of changes in Standard 90.1-2019, compared to the previous 90.1-2016 edition, as applied in commercial buildings across the United States.  

This document provides recommendations for organizing effective and efficient submittal reviews of projects that follow ASHRAE 90.1 Section 11 and Appendix G.

This document outlines resources to help facilitate compliance documentation and submittal reviews.

The Submittal Reviewer is a professional responsible for reviewing the compliance documentation on behalf of the authority having jurisdiction or rating authority for projects following ASHRAE Standard 90.1 Section 11 and Appendix G. This document outlines the Submittal Reviewer responsibilities.

The Energy Modeler is a professional responsible for performing energy modeling and facilitating completion of the DOE/PNNL ASHRAE Standard 90.1 Performance Based Compliance Form on projects following ASHRAE Standard 90.1 Section 11 and Appendix G. This document outlines the Energy Modeler responsibilities.

This spreadsheet contains detailed end use data results from the Progress Indicator analysis of ASHRAE Standard 90.1-2013 conducted by PNNL.

Summary of the full technical brief which provides requirements for electric readiness that could be incorporated into model residential energy codes. It provides background on the basis and benefits of the provisions, and model code language that can be plugged into the IECC or adapted into other energy codes.

This workbook accompanies the report 'National Cost-effectiveness of ANSI-ASHRAE-IES Standard 90.1-2013' The report provides the full description of this project and the cost estimate methodology as well as some additional details on the cost estimate items.

The Standing Standards Project Committee (SSPC) for ASHRAE Standard 90.1 established a working group to develop an energy credits proposal.  The package of measures proposed for ASHRAE Standard 90.1-2022 includes 32 energy efficiency, renewable energy, and load management measures available. This technical document provides the general description of the proposed energy credit measures, the basis for calculation of potential energy credits, and the demonstration cost effective packages that justify the energy credit requirements by building type and climate zone.

These analyses evaluate the cost-effectiveness of the prescriptive path of the 2018 edition of the International Energy Conservation Code (IECC), relative to the 2015 IECC with amendments for all 50 states and the District of Columbia. The analysis covers one- and two-family dwelling units, townhouses, and low-rise multifamily residential buildings covered by the residential provisions of the 2018 IECC.

This report considers the role of commercial building energy codes in enabling grid-interactive efficient buildings (GEBs). Specifically, it highlights the status of demand flexibility (DF) measures in ASHRAE Standard 90.1. It examines the model code-development process and identifies components preventing the consideration and inclusion of DF measures, including code scope, characterization and analysis of proposed new prescriptive measures, and the time-of-day and geographic differences in their benefits.

PNNL evaluated the cost effectiveness of the changes in the prescriptive and mandatory residential provisions of the 2021 edition of the IECC, compared to those in the 2015 IECC.

Grid-interactive efficient buildings (GEBs) combine efficiency and demand flexibility with smart technologies and communication to provide occupant comfort and productivity while serving the grid as a distributed energy resource (DER). This report includes an overview of relevant BTO research efforts to inform and guide the addition of GEB considerations in the model energy code.

This technical documentation provides background on 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.
