ment and verification of building energy performance, emphasizing
the changes in energy performance that result from implementation
of energy conservation measures in buildings. Many building energy
conservation measures have the potential to positively or negatively
affect indoor pollutant concentrations, thermal comfort conditions, and
lighting quality. These and other indoor environmental characteristics
are collectively referred to as indoor environmental quality^1.
IEQ can influence the health and productivity of building oc-
cupants. Small changes in occupant health and productivity may be
very significant financially, potentially exceeding the financial benefits
of energy conservation (Fisk and Rosenfeld, 1998). It is important that
these IEQ considerations be explicitly recognized prior to selection and
implementation of energy conservation measures^2. Consequently, the
primary purpose of this document is to provide information that will
help energy conservation professionals and building owners and man-
agers maintain or improve IEQ when they implement building energy
conservation measures in non-industrial commercial and public build-
ings^3. This document also describes some practical IEQ and ventilation
measurements that, in certain circumstances, can also help energy con-
servation professionals maintain or improve IEQ.

Hospitals and other health care facilities have special indoor air
quality requirements that are not addressed in this document. - The term indoor air quality (IAQ) is sometimes used for the same purpose,
although IAQ is also used more narrowly in reference to the levels of pol-
lutants in indoor air. - Conversely, when selecting measures to improve IEA, the potential impacts
of these measures on building energy use should be considered. This docu-
ment does not directly address this situation but it includes some relevant
information. - This document is not intended as substitute for local codes or as a guide
