✦ Synopsis

The paper discusses the influence of some simple type of louvers on room air motion. The average indoor wind velocity was chosen as a parameter for comparing the performance of a louvered window with that of a non-louvered window. The area of the regions over which air motion is increased and also that over which it is decreased due to a louver, was determined. It is observed that when a horizontal projection (sun shade) is provided at the top of a window the air motion at sill level decreases but higher up it increases. The box type louvers accelerate the room air motion when out door wind impinges normally on the window but produces a reduction for the obliquely incident wind. The semibox type (L-shape) louvers promote air motion at all levels for all values of angle of incidence where as for multiple louvers the situation is reversed at sill level.
