A Comprehensive Evaluation of Cooling Load Reduction Potentials of Self-Ventilated Cavity Wall in the U.S

Ri Na, University of Nebraska - Lincoln

Abstract

The cooling load reduction potentials of self-ventilated cavity walls (SVCW) were quantitatively investigated through numerical simulations. Parametric and correlation studies were conducted to understand the impacts of typical wall geometric configurations on the performance of reducing cooling load. After quantifying the impacts of temperature and wall geometries, estimates of cooling-load reduction potentials for three summer months in four different locations in three climate regions were calculated. In addition, peak-time cooling-load reduction potentials of SVCW were investigated quantitatively to understand the impact of SVCW on reducing peak cooling load in summer time. Numerical simulation results were validated either through the published data set, or through the experimental data from thermal imaging. The results of the investigations suggested that SVCW system has significant potentials in reducing building’s summer cooling load across the US. Moreover, SVCW system also performs very well in reducing peak summer cooling load. The research outcomes can be applied to both new buildings and retrofitting of existing buildings.^
