Standard 62.2 is the most used and only ANSI-approved residential ventilation standard in the country. It has continuously evolved to meet the needs of the residential market since 2003. The latest version is just hitting the streets now. It covers a larger span of the market than before, includes new flexibilities and provides a host of small improvements. This seminar teaches the new compliance requirements, discusses what has changed, examines the application of the revised standard in existing homes and describes ongoing initiatives and options being explored by the committee.
1 Standard 62.2-2016: Overview and Major New Changes
 |
Paul W. Francisco, University of Illinois at Urbana-Champaign |
The 2016 edition of ASHRAE Standard 62.2 – Ventilation and Indoor Air Quality for Residential Buildings – has just been released. This presentation provides an overview of the standard’s requirements, as well as a brief discussion of addenda that have been incorporated since the 2013 edition, including two significant scope changes.
2 Tips and Traps for Existing Home Ventilation Strategies Under 62.2

Richard Karg, Residential Energy Dynamics |
Application of Standard 62.2 in existing homes can range from relatively easy to exceptionally challenging depending on age of the home, its physical characteristics, and quality of construction. This presentation provides guidance on cost-effective compliance with 62.2 in existing homes while avoiding unintended consequences.
3 Equivalence and Superposition in ASHRAE 62.2

Iain Walker, Ph.D., Lawrence Berkeley National Laboratory |
Standard 62.2-2016 added a new section that includes provisions for real-time tracking of variable ventilation. Smart ventilation controls are permitted to shift ventilation from times of high energy penalty to lower energy penalty, with the potential for significant ventilation-related energy savings. An ongoing initiative within the committee is an improvement to the calculations that combine natural infiltration with mechanical ventilation. These new calculation methods are intended to account for non-linear air flow interactions. This presentation discusses the technical background behind these changes and give examples of application of the new calculations.
