IEQ Applications: International Standards for Better Indoor Air Quality

Journal

Interest in indoor air research has increased significantly in recent decades. However, enforceable IAQ standards are scarce while various ambient (outdoor) air quality standards and regulations have been established internationally to protect public health.

Developing Indoor Air Quality Standards: Reflecting on a White House Summit

Journal

This column presents ASHRAE’s current positions and activities related to the development and improvement of indoor air quality standards, which include retro-commissioning of existing buildings and HVAC systems, maximizing outdoor air ventilation, upgrading building filtration and the possibility of developing health-based ventilation metrics for use in the built environment.

Air Filter Performance: New Method for Testing

Journal

The International Standards Organization is preparing to issue a new standard for testing and rating air filters, ISO 16890. The procedures offer possibilities for including local particulate air pollution conditions and indoor air quality levels in the selection of air filter systems for HVAC systems. This article introduces the standard.

Designing Building Ventilation to Exceed Codes and Standards

Journal

The standards for indoor air quality (IAQ) are essential for setting minimum ventilation rates for buildings to ensure a healthy environment for everyone. However, the prescriptive and mostly consensus-based recommendations in the codes and standards are not sufficient to address the details of ventilation design. In addition to the ventilation rates, the indoor airflow patterns and the resulting flow path of airborne contaminants can significantly affect the quality of air in the breathing zones of occupants. This article demonstrates how the science of computational fluid dynamics (CFD) can help analyze and optimize the ventilation designs. CFD analyses, along with the Spread Index—a ventilation effectiveness metric—can complement the codes and standards to create more comprehensive and human-centric ventilation designs.

Standard 62.1: Problems, Perceptions, and Panaceas

Journal

ASHRAE Standard 62 was first published in 1973, with the title "Standards for Natural and Mechanical Ventilation." The most recent version, des15ignated as 62.1 and titled Ventilation for Acceptable Indoor Air Quality was published in 2004, with some relatively minor revisions added since that time in a supplemental publicaiton. Throughout its existence, Standard 62 has generated controversy, but at the same time it has served the building industry and the public as the most prominent standard on ventilation and indoor air quality (IAQ).
