|Air-Quality Workshop Will Explore Performance Metrics for Indoor Environments
ASTM Subcommittee D22.05 on Indoor Air Quality will sponsor the workshop, Performance Metrics for the Indoor Environment Oct. 14, 1-5:30 p.m. at the Norfolk Waterside Marriott, Va. The subcommittee invites individuals who evaluate indoor environments and other stakeholders to discuss the feasibility and timeliness of establishing performance metrics for the indoor environment. The free event is open to non-ASTM members and will be held during the Committee-Week activities of ASTM Committee D22 on Sampling and Analysis of Atmospheres, Oct. 14-16.
Workshop coordinators Cindy Howard Reed and Andy Persily are engineers with the Building and Fire Research Laboratory, National Institute of Standards and Technology, Gaithersburg, Md. In order to improve building indoor environmental quality (IEQ), say Persily and Reed, and to evaluate technologies and strategies for realizing these improvements, the building industry and others have identified a need for performance metrics to quantify any of several aspects of the indoor environment including levels of indoor air contaminants, ventilation, odors, thermal comfort, lighting and noise.
Such metrics could then be used to assess IEQ conditions in a specific building space and to evaluate the impact of control technologies intended to improve IEQ. Examples of IEQ metrics include:
Contaminant levels relative to established guideline values;
Weighted combinations of multiple contaminant concentrations relative to guideline values;
Determinations of occupant exposure to one or more contaminants; and
Ventilation rates and thermal conditions relative to recommended values.
IEQ metrics could also address issues of health impacts, productivity and economics, but these will certainly be more challenging.
Several candidate metrics have been proposed, and other approaches merit consideration. At this point in time, say Reed and Persily, it would be beneficial to evaluate the possibilities for the development and application of IEQ performance metrics to assess the current state of indoor environments and to explore additional work and information that is needed to support the development of such metrics.
