Ventilation, Infiltration & Indoor Air Quality

American Conference of Governmental Industrial Hygienists (ACGIH)
The ACGIH offers high quality technical publications and learning opportunities.
Air Infiltration and Ventilation Centre (AIVC)
The AIVC fulfills its objectives by providing a range of services and facilities which include: Information, Technical Analysis, Technical Interchange, and Coordination.
Americlean Services Corp. (ASC)
ASC is a certified SBA 8(a) engineering/consulting firm specializing in HVAC contamination detection, abatement, and monitoring. In addition to highly professional ductwork cleaning and HVAC cleaning services, ASC offers a wide range of other engineering/ consulting/ management services directly related to Indoor Air Quality (IAQ).
California Air Resources Board (ARB) Information
The California Air Resources Board (ARB) carries out a non-regulatory Indoor Air Quality and Personal Exposure Assessment Program (Indoor Program) that includes sponsored research, exposure assessment, development of indoor air quality guidelines, and public education and outreach. The goal of the Indoor Program is to identify and reduce Californians' exposures to indoor air pollutants. The ARB is committed to pursuing actions to prevent indoor pollution and to effectively reduce the significant risk it currently poses to Californians.
The EPB Group's Energy Impacts of IVIAQ
The Energy Performance of Buildings Group at Lawrence Berkeley National Laboratory has compiled a wide variety of information regarding the energy impacts of infiltration and ventilation strategies. This page describes those effort and links to accessible publications as well as an on-line calculation program for estimating residential ventilation and associated energy and cost impacts.
Envirosense Consortium
The Envirosense Consortium is a non-profit organization of strategic companies and other Associations that address Indoor Air Quality (IAQ) issues. The Consortium provides educational programs that focus on proactive solutions for building, product, and maintenance systems.
Heating, Ventilation, and Air Conditioning (HVAC) Resources
From the Environmental Design Library at the University of California, Berkeley.
Indoor Air Quality (IAQ) Quick Finder
From the U. S. Environmental Protection Agency. See also, their Fact Sheet on Ventilation and Air Quality in Offices, and their IAQ Information Clearinghouse: "IAQ Hotlines and Resources" website.
Indoor Air Technologies Inc.
Indoor Air Technologies specializes in indoor air quality (IAQ) and thermal comfort problem solving, measures ventilation system and air filtration system performance, thermal gradients, respirable suspended particulates, radon, hydrogen sulphide, mercaptans, formaldehyde and other volatile organic compounds (VOC's), designs ventilation systems, constructs ECHO System ventilated basements to eliminate typical moisture and odor problems and sub-slab depressurization systems for soil gas mitigation.
International Centre for Indoor Environment & Energy (ICEEE)
The ICEEE encompasses a comprehensive research program funded by the Danish Technical Research Council. The Centre, which compromises a staff of approximately 50 persons from many different countries, is located at the Technical University of Denmark. Research focuses on studies of the effect of the indoor environment on human comfort, health, and productivity.
LBNL Indoor Environment Department
The Indoor Environment Department characterizes and measures indoor pollutants and their sources; evaluates the energy performance of heating, ventilation, and air-conditioning (HVAC) systems in buildings; develops techniques and devices for detecting, characterizing, measuring, and mitigating indoor air pollutants; and works with academia and governmental health agencies to assess the risks to human health from various indoor air pollutants. IEP researchers study ventilation, infiltration, and thermal distribution systems; the nature, sources, transport, transformation and deposition of indoor air pollutants; human exposure to indoor air pollutants; and the health risks associated with this exposure. Pollutants of particular interest include radon; volatile, semi-volatile and particulate organic compounds; and combustion emissions, including environmental tobacco smoke, CO, and NOx.
LBNL/USGS High Radon Project
This high-radon project has been developing a statistical methodology for providing improved estimates of local indoor radon concentrations across the United States. The purpose is to enable State or other agencies to identify high-radon counties, or portions thereof, more precisely so that indoor monitoring and control efforts can be focused more effectively. This page describes the project and how to obtain results.
