Subfloor Air Flow

Other Preventive Measures

Utilization of the Bernoulli principle by way of the design of the roof can result in options that intentionally create low strain circumstances to draw stale air out of the building. By analyzing wind pace and course, and orienting the roof slope into the prevailing winds during periods when natural ventilation is appropriate, correctly located roof openings can draw air out of the constructing.
