Experimental Verification and Performance Evaluation of an Innovative Facade During the Summer Period

Abstract

This paper presents the results of experimental measurements carried out at a Twin Rooms facility under real climatic conditions during the summer period. Based on previous research, two facade prototypes were created. We investigated a simple facade and an innovative double skin facade, which uses solar energy in several stages by transforming short-wave solar radiation into long-wave heat in the cavity of the double transparent facade and using the photovoltaic transformation of short-wave solar radiation into electrical energy. The aim of the measurements is to verify the functionality of the aerodynamics of the narrow cavity, evaluate energy flows through the facade, and assess the efficiency of systems related to solar radiation. The results correlate well with assumptions.
