CLICK HERE for PHPAIDA The Interactive Ventilation Calculator Based on Opening Area combined with Wind, Stack and Mechanical Ventilation

These tutorials are intended to provide the basic information necessary to undertake ventilation prediction and design. They will enable you to :

• Determine ventilation rate (the rate of flow of air into and out of a building);

• Select and incorporate weather data;

• Determine the flow characteristics of openings;

• Identify the leakage characteristics of a building;

• Run a simple ventilation model (which will provide basic design data and ideas for many building types).
