2.2.5 Shading, openings and use of natural ventilation In this region's vernacular architecture, windows, doors, and ventilators all play a significant role in changing the internal atmosphere. The original vernacular homes' doors and windows have also been fixed with wooden blinds from the outside. Selective opening is possible with these blinds (Fig. 2.7). This feature gives tenants more control over allowing desired daylight into their homes. It can also be maintained in such a manner that only dispersed sun radiation enters the interiors. Doors have the same provision and may be controlled in the same way to change the inside atmosphere and maintain comfort. Doors and windows with movable wooden blinds may be opened outside, while internal doors and windows can be opened to the interiors (Fig. 2.7). Natural ventilation and air exchange regulate the temperature within these dwellings. Local wind directions, as well as the positioning of windows, doors, and ventilators, all contribute to this. The year-round high humidity in this climatic zone makes it difficult for the design to make effective use of natural ventilation and air exchange. Controlling the building's heat gain necessitates the use of shading. In this zone's traditional homes, overhangs (Chajja) on windows and roofs are extended outward to serve as overhangs (Fig. 2.8). Extended roofs and window overhangs provide shade as well as protecting the wall from rain damage.
