The facade is lit by single Led pixel, with lights that reflect different parts of the building, highlighting areas of activity within it. Images on façades, referring to natural phenomena and energy, are designed as part of the branding strategy of Hanwha, a leading provider of environmental technologies in the world. Passing vehicles and pedestrians the LEDs are arranged according to new shapes, creating an ever-changing schedule, nearly predominance the imposing mass of the skyscraper.

In response to the request to integrate environmental architecture competition, UNStudio has developed the sustainable façade reactive: its renewal will result in the replacement of opaque panels with transparent glass, isolated, and aluminium structures that will frame the exterior views. The geometry of the shots is further defined by Sun factors and guidance, in order to ensure reduced energy consumption and participate in the preservation of environmental comfort inside.

Solar impact on the building decreased shading provided by tilting the glass relative to the direction of direct sunlight: only the upper part of the South façade is angled to receive direct sunlight and photovoltaic cells are placed on opaque panels in the South/South-East, where it is used an optimal amount of sunlight.

Inside the Hanwha HQ the natural element dominates with large green spaces and furnishings, and two corner cafes to entice users to enter. The lobby of the venue Hanwha connects the Interior with landscape that continues inward and acts as a key driver in building, while natural materials and plants create a relaxing space for visitors which facilitates the possibility of interaction and social exchange.
