DESIGN FOR VENTILATION AND LIGHTING IN RURAL SHELTERS
Product: Design methodology for adequate indoor day lighting and air ventilation
Application: Rural houses.
Feature: The norms for natural illumination and ventilation in rural houses are quite different since most of activities there are performed in the open space. The openings (windows and doors) should provide at least 80 Lux of illumination throughout and 160 Lux in the centre of the room. Similarly ventilation of 3 a.c.h. is essential for comfort requirements in summer and rainy season when outdoor wind speed is 2-5 km/hr. Based on daylight availability data, design parameters are evolved for the location, direction and extent of openings to ensure adequate daylight and breeze indoors.
Commercialisation: Know-how available, incorporated in Indian Standards and National Building Code.
Economy: Adequate daylight and ventilation at no extra cost, saves 20-60% energy.
Investment: --------
Equipment: Nil
Raw materials: Plain window glazing
Institute: Central Building Research Institute.
