A double skin façade is a structural term that refers to the two façades of a building, typically the vertical element, with a cavity in between them. Within that cavity is an air flow. The benefit of this system is the way that it maintains a consistent temperature, a sign that energy is being used efficiently. If you’re cozy and warm in the winter, and cool in the summer, then you probably don’t even think about whether or not your heating and cooling systems are operating at their most efficient levels. But when energy is being lost, and temperatures have to be adjusted, it’s a sign that you’re losing energy. Energy lost is energy wasted and that means money is spent for energy you aren’t using. Installation of an architectural curtain wall can restore the balance of your heating and cooling systems so that the double skin façade takes on some of the work of keeping a building’s interior spaces warmer in the winter and cooler in the summer.
