ASHRAE Standard , “Ventilation for Acceptable Indoor Air Quality,” presently defines the “standard of care” to be exercised by. ASHRAE Standard (Standard ) “Ventilation for Acceptable Indoor. Air Quality” is the new heating, ventilating, and air-. One requirement for implementing the ASHRAE Standard ventilation rate procedure is to provide continuous measurement of the.

There are two major changes in this version of the Standard compared to the version. Creation Date October 15, The 13 voting members of the committee are: Serving as both a federal and a state depository library, the UNT Libraries Government Documents Department maintains millions of items in stadnard variety of formats. However, it requires knowledge satndard contaminants that will be present, acceptable concentrations of these contaminants to protect health and ensure sensory comfort, and sources of these contaminants.
Samet How can the roles of source control and air cleaning be better integrated into the Standard? Dixon, State of Florida P. Once the value of G was determined, the maximum desirable emission rate for all non- occupant indoor sources would be established. The committee consists of 25 designers, equipment manufacturers, regulators, and researchers. ASHRAE Standards are reviewed every 5 years or less, and are updated regularly to incorporate the newest proven technology.
About Browse this Partner. First, the minimum outdoor air flow rate has changed from 2.
Interpretations for Standard 62-1989
This paper highlights some of the key features of the current Standard and summarizes the status of the review process. The Standards are written under strictly administered rules that define committee size; committee balance among affected parties i.
At present, such information is seldom available to the designer, and is often unaffordable to the builder. It has been viewed timeswith 7 in the last month.
Progress in these two areas is key to improving the soundness and usefulness of the two design procedures.
ASHRAE Standard Energy, Cost, and Program Implications. – Digital Library
Daynard, Northeastern University Richard W. What responsibilities do I have when using this report? Grimsrud, University of Minnesota Shirley J. With further development it could be a very useful design tool for evaluating trade-offs between increased ventilation, source management, and air cleaning as options for achieving occupant health 62-11989 comfort.
To make the Indoor Air Quality Procedure practical, Standard 62 may have to list default values of emission factors for various sources staneard on the literatureand give examples of how to use the procedure to calculate total emissions and compare them with values of G.
The Ventilation Rate Procedure might therefore be best suited to supplying effective ventilation for control of occupant odor, thermal comfort, moisture from high-moisture areas such as kitchens and bathrooms, and conditions that discourage the growth and dispersion of microbial contaminants.
Some users of Standard found the application of different ventilation rates for smoking and non-smoking areas confusing, and the recommended maximum concentration of formaldehyde was challenged. All numbers in the examples below are arbitrary except the C values for nitrogen dioxide and particles which are EPA ambient air quality standards, and the 0. In most cases, of course, total air supplied is mostly stanard air; recirculation is used primarily to reduce equipment sizes and energy consumption, and to facilitate good air mixing and control of thermal comfort.
Reports, articles and aehrae documents harvested from the Office of Scientific and Technical Information. Physical Description 55 pages.
The alternative procedure allowed design engineers to use whatever amount of outdoor air they deemed necessary if they could show that the levels of indoor air contaminants were held below recommended limits.
Descriptive information to help identify this report. Wellford What editorial changes need to be made e. Unfortunately, these numbers are sometimes used without a very broad understanding of ventilation and how it relates to indoor air quality.
These issues are listed below along with the chairman of the subcommittee responsible for dealing with each issue: Environmental Stanrard Agency Arthur E.
ASHRAE Standard 62-1989: Energy, Cost, and Program Implications.
stanvard Description Last Updated Jan. Standardretains the two procedures for ventilation design, the Ventilation Rate Procedure and the Indoor Air Quality Procedure. The Standard also introduced an alternative Indoor Air Quality Procedure to permit innovative, energy-conserving ventilation practices. Another special emphasis is on making clearer links between sources of contaminants and control of indoor air quality by ventilation, source management, or air cleaning.
Building designers use the Ventilation Rate Procedure in the vast majority of cases because it is relatively straightforward.
