Since this is unavoidable, building designs can limit unwanted effects while taking advantage of airflow patterns. Modern safety and fire codes may also limit some design options historically used in locations such as stairwells. Fan-assisted ventilation may be required. Additionally, buildings with low ceilings will not see significant airflow from stack effect. Central areas of very wide buildings will not benefit from natural ventilation efforts alone. Natural ventilation doesn’t include humidity control. Before You Rely On The Stack Effectīefore relying on stack effect to provide natural ventilation, consider some of the limits. New buildings designed for natural ventilation should be positioned to catch wind during the summer and block exposure during winter. Interior exhaust openings should be above the supply openings so that the stack effect sweeps stale air up and out. An indirect path allows the movement of fresher air to mix with and remove stale air. Indoor transom windows and interior walls redirect flow through occupied areas. Design features should focus on mixing fresh air with current air and on controlling stack effect within the building. Natural ventilation can save owners and building managers money, up to 30 percent in some cases. Modeling and evaluating scenarios with wind pressure and temperature extremes are also important tools that professionals use to set a plan for specific building needs. Determining where air is most likely to enter the building, either through openings or via leaks, is the first step in controlling it. Some are basic energy-efficiency measures, such as properly sealing and insulating pipe openings in the building envelope to stop in-leakage or designing tight exterior walls. In some cases, building areas exposed to the coldest airflow may have frozen sprinkler system piping.ĭesigners, builders and facility managers can take steps to mitigate the impact from stack effect.
