When the passive technique of night flushing is used correctly with the appropriate construction and architectural features, it can greatly reduce and eliminate the need for air conditioning and reduce peak energy demands. To test the efficiency of night flushing and to demonstrate its energy impact and its effect on building performance, the Lakeview Terrace Library was used as a case study. The library was modeled in IES Virtual Energy Pro, using the information from the building drawings supplied by the architects. After the building was simulated, its architectural features were altered to try to maximize energy efficiency by using night flushing. The night flushing simulations show the importance of internal and solar heat gain on natural ventilation, as well as the role all of the building's features play in natural ventilation. Night flushing offers an energy efficient alternative to HVAC without affecting the occupants comfort level.
