Abstract

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 CEC, 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 in California is the emergence of hybrid natural and mechanical system strategies. The report also provides recommendations for additional research and technology transfer to further advance application of natural ventilation to commercial buildings in California.
