Optimization of Lighting System Lightening consumption in the Spanish health sector is about 1000 GWh/year, which means 0.6% of the national energy consumption, with an emission of 600,000 annual tons of CO2 [31]. [...]it is very important to use efficient lighting with high-performance lights, incorporating low consumption equipment and high-regulation lumen-per-watt lamps. The specific energy saving measures applied were installation of electronic ballast in fluorescent lamps, replacement of fluorescent and incandescent lamps by light-emitting diodes (LEDs), organization of lighting according to activity type, and the limitation of intensity and timing of the controlled lighting by using occupancy sensors. 3.5. [...]at present, Spain does not offer the possibility to incorporate the surplus energy into to the public grid. [...]it is necessary to design these facilities with a self-consumption purpose, based on their annual operative period. [...]in a given healthcare building of 30,000 m2 of built surface area, it is possible to obtain an annual saving of up to €37,152, compared to €6192 in a 4000 m2 building.
