Abstract:
Ventilation evaluation is critical in building operation
and maintenance, in building performance investigations
and in building research. However, activities in these
fields often do not always employ consistent or reliable
approaches to ventilation evaluation. One reason for
the variable consideration of building ventilation is
the complexity of ventilation and air movement in large,
multi-zone buildings and the variability of mechanical
ventilation systems in these buildings. Other more
specific reasons include the lack of, or in some cases
the lack of use of, standardized approaches to assessing
building ventilation, the cost and performance
limitations of available instrumentation, and a lack of
understanding of the available instruments and their
use. A project is being conducted at NIST to identify
approaches to improving these evaluations, to develop
selected ventilation assessment protocols, and to
identify research needed to make further advances in the
field. This project has included a characterization of
the applications of ventilation assessment in buildings,
an identification of the objectives addressed by
different approaches to ventilation assessment, and a
review of existing protocols.
