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.

At present, such information is seldom available to the designer, and is often unaffordable to the builder. Gene Tucker ChairU. Some users of Standard found the application of different ventilation rates for smoking and non-smoking areas confusing, and the recommended awhrae concentration of formaldehyde was challenged.

Interpretations for Standard

There is also the approach taken by the European ventilation guidelines. It has been viewed timeswith 7 in the last month.

Now that the revised Standard Standard is available, its usefulness needs to be evaluated. This procedure also describes how to evaluate whether outdoor air quality is acceptable for ventilation, allows for reduction of outdoor air quantities when recirculated air is treated by contaminant removal equipment, and establishes criteria for variable ventilation.

Description Last Updated Jan. This would be consistent with the current statement in the Standard that covers cases “where unusual indoor contaminants or sources are ztandard or anticipated. The committee consists of 25 designers, equipment manufacturers, regulators, and researchers.

Ventilation rates are tabulated for a wide range of residential, commercial, institutional, vehicular, and industrial spaces. Daynard, Northeastern University Richard W. Samet How can the roles of source control and air cleaning be better integrated into the Standard?


Interact With This Report Here are some suggestions for ashrrae to do next. The amounts of outdoor air to be supplied to various types of spaces are conveniently tabulated, and readily used by designers. An appendix, which is not considered a part of the Standard, contains a compilation of criteria and guidance for a broader range of contaminants.

Identifier Unique identifying numbers for this report 62–1989 the Digital Library or other systems. Guidelines for Ventilation Requirements in Buildings.

Increased ventilation for major non-occupant sources should be evaluated along with source control and air cleaning. Creation Date October 15, Special emphasis is being given to the health and comfort basis of the Standard and to describing the complementary roles of source control and air cleaning for providing good indoor air quality. Once the value of G was determined, the maximum desirable emission rate for all non- occupant indoor sources would be established.

The Standard is reviewed every 5 years or less, and updated as needed to incorporate new information or improve its usefulness to building designers and code officials. Mamayek, lllingworth Corporation Bjarne W. This standard is being continually reviewed and updated to reflect awhrae information, especially on public health aspects of indoor air and sources of indoor contaminants. The alternative procedure allowed design engineers to use whatever amount of outdoor asheae they deemed necessary if they could show that the levels of indoor air contaminants were held below recommended limits.

Interpretations for Standard 62-1989

The 13 voting members of the committee are: Second, the distinction between “smoking allowed” and “smoking prohibited” has been removed. Reports, articles and other documents harvested from the Office of Scientific and Technical Information. Energy, Cost, and Asjrae Implications. Ten types of prototypical commercial buildings used by Bonneville for load forecasting purposes were examined: ASHRAE Standards are reviewed every 5 years or less, and are updated regularly to incorporate the newest proven 622-1989.

Perhaps it is most reasonable to expect ventilation to provide, as a minimum, that portion of indoor air quality control that relates to thermal comfort and sensory comfort from occupant odor. In spaces where sources were stronger, trade-offs between source management e.

ASHRAE Standard Ventilation for Acceptable Indoor Air Quality

Collections This report is part of the following collection of related materials. Instead of prescribing outdoor air ventilation rates for various types of indoor spaces, the Indoor Air Quality Procedure is based on maintaining acceptable concentrations of “all known contaminants of concern.

A table of design values 662-1989 this correction factor could be developed, similar to the table of such values in the European ventilation guidelines The committee is currently addressing eight issues in preparation for deciding what aspects of the Standard need most attention.

Usage Statistics When was this report last used? Health-based criteria and guidelines are listed for the following contaminants: Environmental Protection Agency Arthur E.
