The recently built Korean green skyscraper designed by Adrian Smith + Gordon Gill Architecture features one of the most efficient solar electric facades in the world.
Federation of Korean Industries Tower in Seoul is equipped with an advanced photovoltaic wall system that reduces energy usage while generating power. The building stands for a height of 800 foot. The overall added cost is nearly zero.
The structure exhibits the accordion-style exterior wall. The integrated photovoltaics (BIPVs) are attached to this wall pointing upwards.
At the same, its glazing is angled toward the ground. The simple design of the tower exploits the potential of the panels by giving them a preferred orientation.
The glass enables the reflection of a dramatically larger percentage of heating during the summers. Thus the mechanism helps in reducing the expense regarding cooling.
Several among the floors of the tower will have full glazing in the upper portion. This helps in reducing the monotonous look of the building.
Moreover it enables deeper light penetration into the building. An adjacent conference center inside the tower resembles a giant glass oval, which creates a counterpoint to the rectangle-shaped tower.
The overall cost of construction is not significantly more than a normal, but the efficiency of the design will provide a quick payback to the building owner.
By taking advantage of a generous renewable tax credit, it has been said that the tower will be paid seven times more for its electricity than what it pays.
