This study expands upon previous research by analyzing the energy impacts of an intermittent or scheduled ventilation system on sensible and latent cooling loads. The summer months of May through September for three geographic locations that exhibit warm summer climates are investigated. Sensible and latent thermal loads are estimated, however, conversion to an equivalent electrical load is not performed. The results show that a reduction in ventilation-based thermal loads is realized when using intermittent ventilation schemes in geographic areas with large diurnal temperature variations and low humidity. Areas with smaller temperature variations can benefit to a much smaller degree, but non-compliant ventilation schemes can still be used to realize energy savings under certain circumstances.
