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.

This document lays out the U.S. Department of Energy’s (DOE’s) methodology for evaluating the cost-effectiveness of energy code and standard 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 life-cycle cost (LCC) economic analysis procedures.

This letter certifies that Minnesota has reviewed the provisions of its residential building code regarding energy efficiency and made a determination as to whether it is appropriate for Minnesota to revise its residential energy code.

The purpose of this analysis is to examine the cost-effectiveness of the 2010 edition of ANSI/ASHRAE/IES1 Standard 90.1.  PNNL analyzed the cost-effectiveness of changes in Standard 90.1 from 90.1-2007 to 90.1-2010, as applied in the United States.

The purpose of this analysis is to examine the cost-effectiveness of the 2013 edition of ANSI/ASHRAE/IES1 Standard 90.1 (ANSI/ASHRAE/IES 2013). PNNL analyzed the cost-effectiveness of changes in Standard 90.1 from 90.1-2010 to 90.1-2013, as applied in commercial buildings for each state in the United States.

The purpose of this analysis is to examine the cost-effectiveness of the 2016 edition of ANSI/ASHRAE/IES Standard 90.1, which is developed by the ASHRAE Standard Standing Project Committee (SSPC) 90.1, and is the model energy standard for all commercial buildings and multifamily residential buildings over three floors.
