The development of the lighting design for the façade hinged on finding an approach that would create a strong identity, while complementing the ultra-sharp language of the architecture and clarity and regularity of the joint-free glass. Multiple tests and studies were conducted to assess the effects of both daylight and artificial lighting approaches on the glass tubes and on the art within the gallery. It was crucial to ensure the solution was not compromised by unintended reflections, apparent distortion and that the light would not damage the art.
