INTRODUCE DAYLIGHT TO THE DEEP PLAN Obtain a minimun illuminance of 500 lux for the whole reading room area, and distribute uses accordingly.

ADAPT SPACE FOR COMPUTER USE Avoid all direct sunlight coming from the façade by redesigning the shading system. Reduce space contrast and glare for work spaces using an dynamic facade

DESIGN A TRANSITION SPACE Use the existing library distribution to generate a sequence of exposures to daylighting from the dark entrance to the extremely bright reading areas.

REDUCE THE ENERGY USE FOR LIGHTING Quantify the reduction of introduction of daylighting.
