DOE Determines ASHREA Standard 90.1 Improves Energy Efficiency – USGlass Magazine & USGNN News

The U.S. Department of Energy Confirms ASHRAE Standard 90.1-2022 Increases Energy Efficiency in Commercial Buildings

Introduction

The U.S. Department of Energy (DOE) has confirmed that ANSI/ASHRAE/IES Standard 90.1-2022, Energy Standard for Sites and Buildings Except Low-Rise Residential Buildings, will increase energy efficiency in commercial buildings subject to the code.

DOE Determination

DOE is required by law to issue a determination as to whether the latest edition of ASHRAE Standard 90.1 or the newest version of the International Energy Conservation Code will improve energy efficiency compared to the previous edition of the corresponding standard or code.

DOE determined that Standard 90.1-2022 will “achieve greater energy efficiency in buildings subject to the code.” It estimates national savings in commercial buildings of:

• 8% gross site energy;
• 4% gross source energy;
• 9% gross energy cost; and
• 3% gross carbon emissions.

“Standard 90.1-2022 adds several important changes, including an expanded scope addressing building sites and modest requirements for onsite renewables,” write DOE officials in their determination. “When accounting for the impact of onsite renewable energy systems, the national average site energy savings estimate increases from 9.8% to 14%.”

Implementation

States must now certify that they have reviewed the provisions of their commercial building code regarding energy efficiency and, as necessary, updated their codes to meet or exceed the revised Standard 90.1.

SDGs, Targets, and Indicators

1. SDG 7: Affordable and Clean Energy

   • Target 7.3: By 2030, double the global rate of improvement in energy efficiency
   • Indicator 7.3.1: Energy intensity measured in terms of primary energy and GDP

2. SDG 11: Sustainable Cities and Communities

   • Target 11.6: By 2030, reduce the adverse per capita environmental impact of cities, including by paying special attention to air quality and municipal and other waste management
   • Indicator 11.6.2: Annual mean levels of fine particulate matter (e.g. PM2.5) in cities
