Natural ventilation has the potential to reduce first
costs and operating costs for some commercial buildings
while maintaining ventilation rates consistent with
acceptable indoor air quality. While a recent surge of
interest in Europe has advanced natural ventilation
technology, much work is needed before this potential
can be realized in the U.S. This report reviews the
application of natural ventilation in commercial
buildings, the technology, its potential advantages and
related issues that need to be addressed. 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 also addresses opportunities and issues specific
to the application of natural ventilation to commercial
buildings in California including analysis of climate
suitability via a new ventilative cooling metric,
consideration of ambient air quality, and discussion of
relevant codes and standards. Finally, current design
and analysis processes and tools are reviewed and a plan
for the development of new design and analysis guidance
and tools is described.
