Aesthetic and Energetic Rehabilitation of 6 Buildings Using Composite Panels

The task of rehabilitating buildings has been increasingly encouraged and celebrated for some reasons: first, by renovating and not demolishing, a large part of the material resources present are used, reducing the use and exploitation of raw materials and, in certain cases, the memory and the original urban fabric are preserved. A good rehabilitation also incorporates the modernization of the building to increase its energy efficiency, readjustment of facilities and the correction of pathologies, making it coherent with the demands of current users. For the building's owners and users, this means a better quality of life and, also very important, an appreciation of it. An element that plays a fundamental role in rehabilitation is the façade, which combines aesthetics and performance.

How Do Double-Skin Façades Work?

Double skin façades. Almost a self-explanatory name for façade systems consisting of two layers, usually glass, wherein air flows through the intermediate cavity. This space (which can vary from 20 cm to a few meters) acts as insulation against extreme temperatures, winds, and sound, improving the building's thermal efficiency for both high and low temperatures. Perhaps one of the most famous examples of double-skin facades is Foster+Partners' 30 St Mary Ax Building, "The Gherkin."

The airflow through the intermediate cavity can occur naturally or be mechanically driven, and the two glass layers may include sun protection devices.
