In 2006 I was contacted by the management of the hotel to redesign the architectural lighting. We began by modifying and where necessary adding to the existing though inefficient decorative incandescent light in the corridors and elevator access halls. After that we began designing new lighting for a substantial group of 48 "Sheraton", or "Deluxe Premium" rooms which were to have new décor. Following this project the intention was to do a general revision of the lighting in the other types of rooms as well as in the meeting rooms. From the very start there was a strong suggestion on the part of the management to design with particular attention being paid to the prohibitive costs, both real and in energy consumption, of managing the illumination, costs which were increasing exponentially. Most of the areas since they were designed in different periods, in the recent and not so recent past, had varying kinds of décor and almost always decorative lighting which used massive quantities of incandescent bulbs in chandeliers, appliqués etc..
