Top right Wery opticians in Braine-le-Château, Belgium was completed in 2009 and features LEDs sandwiched between the panes of glass. Above left The lighting of Vinçotte’s offices in Wallonie, Belgium are intimately and delicately tied to the architectural forms, lines and materials. Above right The KBL European Private Bankers building in Luxembourg utilises 75x150cm vertical granite plates as reverberating pixels as LCD screens would do. 850 independent granite plates allow for unlimited lighting possibilities.
Aubin’s Cathedral in Brussels, Hediger used mostly 20, 35 and 70W metal iodide lamps (3200K), positioned high up to uplight the architectural features of the building while remaining hidden from view. Metal iodides (4200K) lit the black and white marble floor. On this project and others, at the end of the day there should be a smooth transi- tion between daylight and artificial lighting believes Hediger.
Using building components as lighting re- flectors is another noticeable aspect of her work, as seen in the lighting of the Dexia Tower and the KBL European Private Bankers building in Luxembourg.
In 2003, Hediger put forward a plan to light a new glass office tower in Brussels with LEDs. At that time, they had yet to be “taken up and used like today. Nevertheless I knew this lighting technique was the most sensible, the best adapted for this type of architecture,” she says. “It was a novel and innovative idea—lighting a facade from the inside.”
The main idea was to bounce LED light from 220,000 RGB LEDs, housed inside 4,184 LED bars, off the closed window blinds. The LED bars were built into roughly three quarters of the building’s window panes, totalling
6,000, which turned each window into a giant rectangular pixel on an enormous 38- storey high screen, controlled by computer and a DMX cable system.
On another office lighting project, this time in Luxembourg, Hediger used the building’s granite facade as a reflector. For the KBL European Private Bankers building “the artistic concept,” she says, “utilises the 75- by-150-centimetre vertical granite plates as reverberating pixels as LCD screens would do. 850 independent granite plates allow for unlimited lighting possibilities. A huge multi-colour patchwork of colours spreading over the various dimensions, sculpting the building’s forms.” Hediger’s current workload includes lighting several Brussels landmark sites, such as the 15-16th century gothic church the Eglise du Sablon, the eighteenth century listed Quartier du Béguinage, and the Brussels Stock Exchange.
But large or small, the lighting projects Hediger works on always have an element of emotion introduced into them. “My job is to create emotion,” she says. “The work of a lighting designer is to bring emotion to built works, whatever they are.”

HIGHLIGHTS
Projects that you would like to change: Although I’m rather proud of the simplicity and the soft lighting in Saint Aubin’s Cathedral in Namur, I would develop a new lighting concept. Through new technologies, I would fine tune the colour and lighting, controlled and measured intelligently, for a subtler reading of the architecture.
Lighting hero: Yann Kersalé, for his artistic vision and his aim of not conforming to traditional rules in lighting, and bending the rules to suit his own vision.
