The Natural Physical Cavity Energy Regime of Double-Skin Facade

Abstract:

The subject of the paper is natural physical cavity of double-skin corridor type facade with year-round open circuit and effective height equal to height of one floor. Goal of the paper is quantification of thermal, aerodynamic and energy regime of this natural physical cavity. Methodology of the paper is long term in-situ experimental research (that means under the load of real conditions of the exterior climate on the building), confrontation of the theory and experiment and scientific polemic to new knowledge. Description of experimentally investigated double-skin facade. Description of the experiment in-situ (basic data, monitored physical parameters, measuring technology). Presentation of research results. New knowledges about regime of natural physical cavity of double-skin facade under windless climate conditions and under wind climate conditions. New knowledges lead us to the most important piece of knowledge about the real maximal increase of the temperatures in the cavity, which is the decisive factor for building ecology (natural ventilation from the cavity) and equally for energy (energy consumption) of a building with double-skin facade.
