1. Improvement of the system of lightning Sergi Ruiz Jose Correa

2. Introduction Reduce the consumption Reduce the consumption We are going to changing the lamps We are going to changing the lamps We are going to install presence sensor We are going to install presence sensor

3. Solution We will change fluorescent to fluorescent led We will change fluorescent to fluorescent led We will change too, lamps to low- consume lamps We will change too, lamps to low- consume lamps And we will install presence sensors, the diagram of sensor is this: And we will install presence sensors, the diagram of sensor is this:

5. ROI ROI it is the time in which we will save the money of the investment. ROI it is the time in which we will save the money of the investment. To recover the investment in 1.61 years To recover the investment in 1.61 years ROI = Investement / Savings = 10391.35€ / 6437.55€ = 1.61 years ROI = Investement / Savings = 10391.35€ / 6437.55€ = 1.61 years 13h / day · 20days / month · 9 months · 18341W = 42917 kWh 13h / day · 20days / month · 9 months · 18341W = 42917 kWh 42917 kWh · 0.15 € (kWh) = 6437.55€ 42917 kWh · 0.15 € (kWh) = 6437.55€ Power before: 53455W Power before: 53455W Power alter: 35114W Power alter: 35114W Power saving = 18341W Power saving = 18341W

6. ENVIRONMENTAL PRINT With the environmental print, we can figure out how much grams of CO2 are we saving to the environment by reducing the power consumption With the environmental print, we can figure out how much grams of CO2 are we saving to the environment by reducing the power consumption With the new installation, obviously, the pollution generated by us is reduced. With the new installation, obviously, the pollution generated by us is reduced. Old installation: 53455W · 300g Co2 / (kWh) = 16036500 Old installation: 53455W · 300g Co2 / (kWh) = 16036500 New installation: 35114 · 300g Co2 / (kWh) = 10534200 New installation: 35114 · 300g Co2 / (kWh) = 10534200 Improvement of the environmental print = Improvement of the environmental print = = 16036500 – 10534200 = 5502300g C02 / (kWh) = 16036500 – 10534200 = 5502300g C02 / (kWh)
