ASHRAE Standard 90.2-2018 and the Pathway to High-Performance Residential Buildings
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
Dr. Theresa Weston is a building science research professional specializing in the durability and energy efficiency of buildings.
Theresa started The Holt Weston Consultancy in November 2020 to foster innovation of building materials, and products to improve the resilience and sustainability of buildings. Prior to starting the Holt Weston Consultancy, Dr Weston was a DuPont Laureate with the Dupont Safety and Construction business, having worked for DuPont for 35 years. DuPont Laureate is the highest technical professional level in the DuPont company.
Theresa received her Bachelor of Science degree in Chemical Engineering from the Massachusetts Institute of Technology, and Masters and PhD degrees in Chemical Engineering, both from the California Institute of Technology.
While at DuPont, Theresa demonstrated a track record of anticipating the need for new technology through the strategic analysis of technology trends and driving the deployment of innovation in the marketplace. She is an inventor on four patents, two of which introduced new product categories into the construction market: 1) Development of industry’s first “drainage wrap”, creating a new water resistive barrier category [US6355333B1 “Construction Membrane” (2002)], and (2) Introduced the category of “formable window flashing” [US7351296B2“Stretchable Flashing Materials and Processes for Making” (2008)].
Dr. Weston is a 25-year member of ASHRAE, having served on the Technical Activities Committee, the Standards Committee and as the Chair of the Residential Buildings Committee, as well as serving on a number of Technical and Standards Project Committees. As chair of ASHRAE 90.2 ANSI/ASHRAE/IES Standard 90.2-2018, Energy-Efficient Design of Low-Rise Residential Buildings, Theresa led the committee to transform the standard to a leadership standard. She was also a member of the project committee which produced the initial publication of ASHRAE Standard 160 Criteria for Moisture-Control Design Analysis in Buildings.
Theresa is active with industry standard and code development activities outside of ASHRAE, including with ICC, and ASTM. She chairs ASTM E06.41 the Performance of Buildings Subcommittee on Air Leakage and Ventilation. She currently serves on the ASTM Committee on Publications and as a member of the ICC Residential Code Interpretation Committee.
Dr. Weston is a prolific author and industry speaker. Recent activities include chairing an ASTM Symposium and resulting special technical publication on Whole Building Air Leakage: Testing and Building Performance Impacts (STP1615) as well as presentations at ASHRAE, EEBA and RESNET Conferences. She is the Vice-Chair of the ASHRAE sponsored Buildings Conference Series.
