Lattice windows as a natural ventilation strategy in hot, humid regions

These paper concerns the role of lattice windows in enhancing resident's expectation of comfort ventilation in such places, especially unconditioned buildings which higher air speed is an important strategy to minimize discomfort from high temperature and humidity, especially that some architectural requirements like privacy call for placing openings in certain places that could lead to a poor ventilation in this occupied zone, unless air flow is directed by using some architecture elements in a desired direction by using special inlet opening like lattice windows.

A model room used in Computational fluid dynamics CFD simulation program Ansys Fluent version,14.5 to figure out how lattice window delivers nature ventilation, Windows geometry, wing walls and side windows were observed how they affect wind direction and pressure difference to figure out its impact on room ventilation, A field measurement study in multi-story building with lattice windows were made by using Nova-Lynx weather station to observe internal ventilation speed and distribution with synchronous external wind.
