Indoor air quality (IAQ) problems are not
limited to homes. In fact, many office buildings have significant air pollution sources. Some of these buildings may be inadequately ventilated. For example, mechanical ventilation systems may not be designed or operated to provide adequate amounts of outdoor air. Finally, people generally have less control over the indoor environment in their offices than they do in their homes. As a result, there has been an increase in the incidence of reported health problems.

I-BEAM updates and
expands EPA's existing Building Air Quality guidance and is
designed to be comprehensive
state-of-the-art guidance for managing IAQ
in commercial buildings. This guidance was designed to be used
by building professionals and others interested in indoor air quality in
commercial buildings. I-BEAM contains
text, animation/visual, and
interactive/calculation components that can
be used to perform a number of diverse tasks.

To gain a better understanding of
indoor air quality (IAQ), EPA's Office of Radiation and Indoor Air conducted a
major study of IAQ in public and commercial office
buildings. This study, the Building Assessment, Survey and Evaluation (BASE)
study, was a cross-sectional study of 100
randomly selected office buildings.
Publications describing the study and summarizing
preliminary results are
available on this website.

In
1999, EPA completed an extensive modeling
study to assess the compatibilities and
trade-offs between energy, indoor air
quality, and thermal comfort objectives for
HVAC systems, and to help formulate
strategies to simultaneously achieve
superior performance on each objective.
Variations of Constant Volume (CV) and
Variable Air Volume (VAV) HVAC systems were
modeled in three different climates-hot and
humid (Miami), temperate (Washington D.C.),
and cold (Minneapolis). Buildings included
several variations of an office building,
plus a school, and an auditorium. Go
