Cost-Effectiveness of ANSI/ASHRAE/IES Standard 90.1-2019 for Wyoming

Abstract

Moving to the ASHRAE Standard 90.1-2019 (ASHRAE 2019) edition from Standard 90.1-2016 (ASHRAE 2016) is cost-effective for Wyoming.Standard 90.1-2019 will provide an annual energy cost savings of $0.063 per square foot on average across the state.It will reduce statewide CO2 emissions by 1.3 MMT (30 years cumulative), equivalent to the CO2 emissions of 288,200 cars driven for one year.Updating the state energy code based on Standard 90.1-2019 will also stimulate the creation of high-quality jobs across the state.Standard 90.1-2019 is expected to result in buildings that are energy efficient, more affordable to own and operate, and based on current industry standards for health, comfort, and resilience.The tables below show the expected impact of upgrading to Standard 90.1-2019 from a consumer perspective and statewide perspective.These results are weighted averages for all building types in all climate zones in the state, based on weightings shown in Table 4.The methodology used for this analysis is consistent with the methodology used in the national costeffectiveness analysis. 1 Additional results and details on the methodology are presented in the following sections.
