Natural ventilation has the potential to reduce the
energy required for cooling and ventilating commercial
buildings while still providing acceptable thermal
comfort and indoor air quality. While a recent surge of
interest in Europe has advanced natural ventilation
technology, much work is needed to realize this
potential in California and the rest of the U.S. This
report discusses the impact of natural ventilation
strategies and design issues for California applications
and provides input to ASHRAE Standard 62 and California
Title 24 based on research performed by NIST that has
been previously reported (Emmerich et al. 2001 and Dols
and Emmerich 2002), additional work completed recently
by NIST for the California Energy Commission, other
completed and ongoing research by NIST, and other recent
published literature. One area identified as a key to
the realization of the potential advantages of natural
ventilation is the emergence of hybrid natural and
mechanical system strategies. The report provides
recommendations for additional research and technology
transfer to further advance application of natural
ventilation to commercial buildings.
