ASHRAE STANDARD 62-1989 PDF

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.

ASHRAE Standard Ventilation for Acceptable Indoor Air Quality

Interact With This Report Here are some suggestions for what to do next. To make the Indoor Air Quality Procedure practical, Standard 62 may have to list default values of emission factors for various sources based on the literatureand give examples of how to use the procedure to calculate total emissions and compare them with values of G. At present, such information is seldom available to the designer, and is often unaffordable to the builder. Grimsrud, University of Minnesota Shirley J.

Perhaps a useful form of such information would be tables of maximum emission rates from non-occupant indoor sources, for the various contaminants or source emission mixtures of concern. The maximum desirable emission rate for all non-occupant indoor sources affecting the space, given the ventilation rates prescribed by the Ventilation Rate Procedure, might be defined simply as: This would be consistent with the current statement in the Standard that covers cases “where unusual indoor contaminants or sources are present or anticipated.

Progress in these two areas is key to improving the soundness and usefulness of the two design procedures. Second, the distinction between “smoking allowed” and “smoking prohibited” has been removed.

Consensus on acceptable concentrations is available for only a very limited number of contaminants, and there are very limited data on emission rates of contaminants from sources. The Ventilation Rate Procedure prescribes the rate at which ventilation air must be delivered to a space and various means to condition that air. For presentation at 5th.

Showing of 59 pages in this report. Description Last Updated Jan. Taylor How can the coverage of zshrae ventilation be improved in Standard 62? Health-based criteria and guidelines are listed for the following contaminants: However, it requires knowledge of contaminants that will be present, acceptable concentrations of these contaminants to protect health and ensure sensory comfort, and sources of these contaminants.

Interpretations for Standard 62-1989

Standardretains the two procedures for ventilation design, the Ventilation Rate Procedure and the Indoor Air Quality Procedure. The committee is currently addressing eight issues in preparation for deciding asurae aspects of the Standard need most attention.

Persily Should Standard 62 go beyond design and deal more explicitly with air quality management during all phases of the life of a building? Authors Steele, Tim R.

Wellford What editorial changes need to be made e. Unique identifying numbers for this report in the Digital Library or other systems. Once the value of G was determined, the maximum desirable emission rate for all non- occupant indoor sources would be established. Sherber How should ventilation effectiveness be defined and incorporated into the standard? Building designers use the Ventilation Rate Procedure in the vast majority of cases because it is relatively straightforward.

First, the minimum outdoor air flow rate has changed from 2. If these emission rates were not exceeded, ventilation rates prescribed by the Ventilation Rate Procedure would suffice.
