NHN Venture Tower is designed to simulate the interactivity of the web. NHN desired a building that served as an interface between the surrounding community and its employees, and therefore created a conversation at an urban scale. As a deep interactive skin, the facade consists of perforated louvers operated both manually and automated to foster a digital dialogue and contend the changing solar demands. The tenants manual operation of the louvers allows for infinite surface variation and an ever-changing building composition. The project employs a double skin curtain wall system which creates a thermal buffer or plenum to control heat gain, exhaust and the comfort of the NHN employees.
