World’s first ‘Pressure Ring’ façade permits lower energy consumption
German Architects Sauerbruch Hutton have figured out a way to make high-rise buildings green by letting in fresh air without increasing the overall energy demands.
The architects have designed an innovative façade for the KFW Bankengruppe office building in Frankfurt, which is being claimed to be the first of its kind in the world.
The high-tech skin, called the “Pressure Ring” façade, balances pressure throughout the building, allowing occupants to have open windows without letting in too much wind. Sensor-controlled ventilators on the outer skin open and close throughout the day in response to temperature, wind speed and wind direction.
The façade lets in air that is then drawn into offices through floor vents and windows. The ingenious façade cools and ventilates the building, without using any energy-sucking HVAC system. During the winter months, the façade makes sure that inside heat isn’t lost to the surroundings. The façade is expected to help the building consume just a third as much energy as a typical American office building does.
