The recently released ANSI/ASHRAE/IES 90.1-2022 is the latest version of the energy standard for buildings, except low-rise residential buildings. It contains updates and changes to improve energy efficiency in buildings, including:

  • Upgraded lighting power density and lighting controls requirements
  • Increased insulation requirements for building envelopes
  • Improved fenestration requirements for windows and doors
  • More stringent requirements for HVAC systems, including improved efficiency and the addition of commissioning and testing requirements
  • New provisions for electric vehicle charging stations and on-site renewable energy systems
  • A revised process for determining compliance with the standard
  • Addition of new provisions for buildings equipped with microgrid systems.

ASHAE has expanded the standard’s name and scope:  Energy Standard for Sites and Buildings Except Low-Rise Residential Buildings. The expanded name describes energy use or generation — such as parking lot lighting or renewable generation equipment — that is outside the building but at the site. On-site renewables could count as credits towards energy usage across the entire building project, even if located in a parking lot or other on-site location, not only with in the footprint of the building. Previously, exterior and parking lot lighting, which if not provided through the main electric panel in the building, were not within the scope of Standard 90.1 previously.
