The Standard’s “Purpose” and “Scope” are covered in Sections 1 and 2. Our objectives have determined the content. Our discussion of Standard 62.1 will try to mimic the structure of the Standard, provide recommendations for compliance, and highlight methods and assumptions to avoid. Both of these supplemental documents should assist the designer and the facility operator in their understanding of and compliance with the Standard.
Work continues on a Guideline 19P, which is intended to provide design guidance for methods that exceed the minimum requirements of the Standard.
ASHRAE 62.1 SYSTEM BREATHING ZONE DEFINITION MANUAL
The promised 62.1 User’s Manual was recently published in December 2005. The existing Standard became known as 62.1 and the new residential standard became 62.2. In 2003, the scope of the Standard officially changed and a separate ASHRAE committee was formed to address the specific needs of low-rise residential buildings. The result is a final version that is substantially different from the basic ventilation standard we have used since 1989. The latest parent document was republished earlier this year to combine 17 addenda that had been approved subsequent to the original release of the 62-2001 ‘parent’ document in January 2002. At any point in time, the ‘official’ Standard is comprised of both the most recently published parent document and all current addenda. This American National Standards Institute (ANSI)-approved standard has been developed by a Standing Standards Project Committee (SSPC) of the ASHRAE under a ‘continuous maintenance’ protocol. The Standard cannot be understood or properly applied without considering the relationships and interdependencies of requirements of the document. Designers are strongly encouraged to read the entire 19-page document (a total of 44 pages with appendices). This is not a condensed version and this does not cover all requirements of the Standard. Operational precision and design reliability are essential for energy minimization when compliance with 62.1 and energy codes are simultaneous goals. Operational implementation of these requirements can have a sizeable influence on energy usage when applied improperly or incompletely. (ASHRAE) Standard 62.1-2004, ventilation for acceptable indoor air quality (IAQ) in Commercial, Institutional, Industrial, and High rise residential buildings, as it impacts and is influenced by ventilation control requirements, methods, and equipment. This is a summary of American Society of Heating and Refrigeration and Air-Conditioning Engineers, Inc. Design recommendations offered are intended to increase the potential for both predictable compliance and the flexibility to accommodate future changes while providing the greatest control reliability with the most energy-efficient methods. Because of the rate-based nature of both procedures allowed for compliance, this analysis focuses on the practical needs of reliable intake rate control and the risks of indirect controls.
