ASHRAE WI | March 2022 - ASHRAE 90.2: Pathway to High-Performance Residential Buildings

10am Topic Summary: ASHRAE holds a unique position through its standards to define and shape residential building performance. ANSI/ASHRAE/IES 90.2-2018 (replacing the Standard 90.2-2007) is a leadership standard that presents a new approach to deliver residential building energy performance and which results in buildings with higher energy efficiency than those built to the IECC-R. Consequently, ASHRAE 90.2 is an option as a turnkey residential stretch code. The path to creating ANSI/ASHRAE/IES 90.2-2018 as a leadership standard was initiated by a Standards Advisory Panel recommendation to the ASHRAE Technology Council that set goals for a leadership residential energy efficiency standard. Key to meeting the leadership goal is the delivery of an accurate, flexible, performance-based tool to enable user creativity in meeting performance objectives. Additionally, ANSI/ASHRAE/IES 90.2-2018 provides leadership by incorporating detailed verification requirements, thus ensuring that the intended energy performance results are achieved. This presentation reviews the structure, requirements and potential applications of ANSI/ASHRAE/IES 90.2-2018. The standard’s development and future path will be discussed.
