摘要

Double skin faf ade (DSF) building is one of the available energy conservation opportunities through recent intelligent buildings. In this research, an innovative point of view to analyze a DSF with energy consideration is appointed, at a glance. To propose this subject, absorbed solar energy plus contributed critical scenarios have been formulated. Continually, the wind energy and temperature and relative humidity effects, and dew formation for condensate appearance on the surface have been technically investigated to complete the simulation. Introducing differential equations is the main part of this study which indicates heat transfer characteristics through the trapped air at skins spacing. In order to cover that, empirical equations plus energy, continuity and momentum differential equations, related to natural convection on vertical thermal shield have been developed. The analytical solution method, with extracted velocity vector and temperature profile, is the other advantage of this research. For a desired building, velocity and temperature variations are defined bounded to facades geometry and spacing. The temperature and velocity profiles have been illustrated by MATLAB software, by increasing grid nodes. Finally, results on techno-economical modeling by which acceptable range of indexes could be explained have been tabulated.
