About

The living façade of the Grande Épicerie is marking up the neighborhood’s urban landscape. The façade is bringing the nature back into the city, aromatic plants, used in cooking or herbalism, come to mix with perennials and grasses. During sunset the animal life in the façade becomes visible, the fireflies are waking up. They are starting slowly: first a single firefly starts to light up, then more and more are starting to communicate until swarms of fireflies are flying around the façade. In the first moment the façade lighting is irritating; it is just turning on in some areas and then they are starting to move around in swarms.

The LED fixture got a customized optical system that is transporting the light outside in front of the plants. The optic is creating a very small direct light with a glare (firefly) and an indirect glow by reflecting most of the light back onto the plants. Dimming the light is decreasing the size of the glow and it seems like the fireflies are flying around the façade. We used warm white light created by a 3000K white LED combined with a green and a red LED to enhance the color of the plants.
