GREEN BUILDINGS IN THE SOUTH VALLEY OF EGYPT
Abstract
Author(s): Dr. George Bassili Hanna
This paper discusses how indoor air temperature is controlled by employing a passive solar technique able to limit the unbearable outdoor weather conditions in a New Urban desert community of Toushky . The passive system employing the “Rock Bed” integrated with a solar chimney to generate an air draft from a thermal tunnel in the ground. A thermal circuit model is developed to describe the complex patterns of heat exchanges. The Finite Difference Method (FDM) is used to estimate the cooling load and the temperatures at different surfaces. Keywords: Passive technique; rock bed; solar chimney; thermal model; FDM; computer simulation.
