ASHRAE enhances performance standard for existing buildings
January 17, 2024 | By HPAC Magazine
The latest edition of Standard 100 includes carbon emissions performance requirements as well as emissions targets for dozens of building types.
ASHRAE has released the latest version of its energy efficiency standard for existing buildings, with an expanded focus to incorporate building decarbonization.
ANSI/ASHRAE/IES Standard 100-2024, Energy and Emissions Building Performance Standard for Existing Buildings is a code-ready building performance standard that provides processes and procedures for reducing energy consumption and carbon emissions through improved energy efficiency and performance of all types of existing buildings, including residential, commercial, institutional, and industrial.
The latest edition of the standard includes carbon emissions performance requirements for existing buildings, as well as emissions targets for dozens of building types.
“As the demand grows for reduced energy use and carbon emission in existing building, there has been heightened interest in Standard 100 within the past year for its potential to shape building regulations,” said 2023-24 ASHRAE president Ginger Scoggins, P.E.
Key updates to the standard include:
- Building requirements to:
- Establish an energy management plan incorporating efficient, low-carbon equipment into capital replacement.
- Achieve energy and emissions performance goals
- Implement an operations and maintenance program for continued building performance.
- Simple compliance mechanism for energy-efficient and low-emission buildings.
- Energy audit and decarbonization assessment and a separate compliance process for building types that do not have energy or emissions targets.
