ASHRAE In The News ASHRAE Chapters and Members in the News ASHRAE Releases Proposed Cabin Air Standard for Public CommentATLANTA – A proposed standard that will define air quality and comfort levels on airplanes has moved one step closer to publication. ASHRAE’s proposed standard 161P, Air Quality within Commercial Aircraft, is open for public comment until Nov. 7, 2005. Also open for review until that date is the proposed companion guideline to the standard, Guideline 28P, Air Quality Within Commercial Aircraft. It provides supplemental information on air quality in air-carrier aircraft and on measurement and testing related to aircraft air quality. The proposed standard would apply to commercial passenger air-carrier aircraft carrying 20 or more passengers. It is intended to apply to all phases of flight operations and to ground operations whenever the aircraft is occupied by passengers or crew members. No such standard encompassing ventilation, thermal comfort and filtration currently exists for aircraft. “The environment aboard commercial aircraft is different than that found in other spaces commonly occupied by people,” Byron Jones, Ph.D., chair of the 161 committee, said. “While aircraft are operated with the comfort of passengers and crew in mind, their safety and health must always be paramount.” Among the reasons aircraft cabin environments are unique are occupant activity levels range from almost completely sedentary (passengers) to active (flight attendants); passengers and crew make up a wide cross section of the general population; and aircraft must be regarded as both a public place (passengers) and a workplace (crew). The proposed standard requires a minimum total air supply of 15 cubic feet per minute (cfm) and recommends 20 cfm per person. The requirement may be met with a mixture of outside air and filtered recirculated air or with 100 percent outside air. A minimum of 7.5 cfm per person of outside air is required. In addition to ventilation requirements, the proposed standard addresses supply air quality and control and monitoring of contaminants to further ensure satisfactory air quality is maintained, according to Jones. Requirements for comfort factors, such as rate of change of cabin pressure, air temperatures and surface temperatures, and minimum and maximum air velocities, also are included. An informative appendix supplements the requirements of the standard with background information on a variety of potential air contaminants, methods of measurements, references to standards and guidelines of allowable levels, and data for levels measured on aircraft. Drafts of ASHRAE’s proposed standards and guidelines are available only during their related public review periods. To obtain electronic draft versions of the Standard 161P or Guideline 28 during the comment periods, log on to ASHRAE Online at www.ashrae.org/standards. ONLINE SEMINAR – EARN CEUs from your Desktop Introduction to Green Buildings and Sustainable Construction - October 20, 2005 This course will present the basic principles related to sustainable construction and green buildings. Included in the course will be a review of the integrated approach to buildings and systems necessary to achieve green/sustainable buildings, developments, and projects. Complying with Requirements of ASHRAE Standard 62.1-2004 - October 26, 2005 ASHRAE Standard 62.1-2004 Ventilation for Acceptable Indoor Air Quality contains many changes from previous versions. The new standard incorporates more than 15 recent addenda.

These will be used to identify ASHRAE products and services related to sustainability. “ASHRAE has long provided ‘engineering for sustainability’ by applying its diverse technology assets to the sustainability movement in energy efficiency, indoor environment and industrial processes,” Ron Jarnagin, chair of a committee developing a roadmap for sustainability for the Society, said. “With growing focus in the industry on the green movement, we need to emphasize that ASHRAE is the engineering engine that drives sustainability.” Jarnagin noted that the Society’s recent efforts include publishing and working on the Advanced Energy Design Guide series, Standard 90.1, which contains a section guiding designers on how to meet requirements for building rating programs, and the ASHRAE GreenGuide, all part of an ASRHAE green “toolkit.” Sustainability also is addressed through other standards and special publications, ASHRAE Journal articles, ASHRAE Learning Institute courses and in the ASHRAE Handbook. User’s Manual Provides Better Understanding of ASHRAE 62.1 ATLANTA – A new user’s manual provides users with a better understanding of the design, installation and operation requirements in ASHRAE’s ventilation standard. The Standard 62.1 User’s Manual explains the requirements of ANSI/ASHRAE Standard 62.1-2004, Ventilation for Acceptable Indoor Air Quality, and contains numerous examples of their application in an easy-to-follow question and answer format. “Because the standard is written in code-intended language, such material could not be included in the standard itself, so the manual helps users better understand the intent and apply it to their work,” Dennis Stanke, chair of the Standard 62.1 committee, said. “It helps users understand what Standard 62.1 requires and how those requirements can be met. It’s a document that designers have needed for many years and will find useful for many years to come.” The manual includes a CD containing a spreadsheet to assist in the standard’s new ventilation rate procedure calculations. The manual was developed through ASHRAE research and partially funded by the National Institute of Standards and Technology, the Air-Conditioning and Refrigeration Institute and the U.S. Green Building Council. The cost of the Standard 62.1 User’s Manual is $55 ($44, ASHRAE members). To order, contact ASHRAE Customer Service at 1-800-527-4723 (United States and Canada) or 404-636-8400 (worldwide), fax 404-321-5478, by mail at 1791 Tullie Circle NE, Atlanta, GA 30329, or visit the ASHRAE.org Bookstore at www.ashrae.org.
