THe paper describes an experimental and numerical study to analyze the thermal performance of bio-climatic building prototype in NIgeria. The roof performs as a solar chimney, generating an air flow through the living space if the building to provide cooling. Experimental tests on a 1:12 small-scale model of the prototype are outlined, and the results, both qualitative and quantitative, are used to validate a two-dimensional flow simulation model, in which the steady state conservation equations of mass, momentum and thermal energy are solved using a finite volume formulation. The experimental and numerical results, expressed in terms of temperature and velocity fields, for two different windows geometries are critically evaluated and compared with good agreement.

Abstract

THe paper describes an experimental and numerical study to analyze the thermal performance of bio-climatic building prototype in NIgeria. The roof performs as a solar chimney, generating an air flow through the living space if the building to provide cooling. Experimental tests on a 1:12 small-scale model of the prototype are outlined, and the results, both qualitative and quantitative, are used to validate a two-dimensional flow simulation model, in which the steady state conservation equations of mass, momentum and thermal energy are solved using a finite volume formulation. The experimental and numerical results, expressed in terms of temperature and velocity fields, for two different windows geometries are critically evaluated and compared with good agreement.
