The objective of this study was to develop the capability to substantially reduce energy use, building degradation and indoor air pollution caused by uncontrolled air flow in nonresidential buildings. For purposes of the study, 'uncontrolled air flow' was defined as air moving across the building envelope or between zones or components of a building, where the pathways of flow, the direction of flow, and the origin of the air are unknown, unspecified, or unintended. The study comes to three major conclusions as follows: 1. Uncontrolled air flow is pervasive in buildings, often resulting in severe -- and sometimes even catastrophic -- consequences, 2. Building practitioners lack the training, methods, and insight necessary to understand and avoid uncontrolled air flow in buildings, 3. Given proper attention, problematic air flows in buildings can be virtually eliminated. Uncontrolled air flow can be avoided in new buildings, and repaired in existing buildings.
