Computer Simulation of Buildings Cooled by Natural Ventilation.

This report presents general information covering the experimental and theoretical basis used to develop the computer simulation of natural ventilation cooling of buildings. Computer input and output and an application example are included. The computer program predicts ventilation rates, mean interior air speed and direction of air flow, interior temperatures, and interior and exterior effective temperatures for a given set of conditions. These conditions are wind velocity, ambient air temperatures, air leakage characteristics of openings, the mechanically induced air flow rates, type of building construction, interior heat loads, and the number of people in the building. The application of this computer model includes the study of the natural ventilation performance of a building, the influence of natural infiltration on mechanical ventilation systems, and the study of smoke in the event of a fire.
