Why Do We Want to Do this?Why Do We Want to Do this?Why Rely on Artificial intelligence, should we not be trying to make our society appreciate the environment?

Yes, as a school we are doing other initiatives in order to make our school realize the environment should come first. However, the work rooms are rooms that is the responsibility of everyone and no one. This is an issue that many school may have where everybody can take responsibility because it is an undesignated zone, the issue is that no one ever does.

This the reason we would like to rely on Artificial intelligence to control our electrical usage in these rooms that are not being taken care of by students or staff.

Doing the work Doing the work This project has been a culmination of two years of research and raw data. To the left is a member of the Electrical Team recording the number of light switches and how many bulbs each switch controls.

The team also takes notice of the number of bulbs in each light bank and how many light banks there are per room. All of these factor into calculating the Kilo Watt usage for each room

The 16 rooms in the 100 area had an overall Kilo Watt consumption of just over 135 Kilo Watts an Hour each day

With Motion sensors and a 50 % reduction in electrical use in these rooms the Kilo Watt usage by the 100’s area would be just below 68 KwH

This shows a money saving of around of around 8 dollars a day.

This means that all 59 rooms will be reducing their emissions from 373 KwH to just above 186 KwH

With all motion sensors put in Dunbarton will be saving daily just above 22 $

The yearly output has Dunbarton putting out 74 000 KwH a year, (200 school days)With sensors and a 50 % reduction we reduce that number to 37 000 KwH for the entire year. This also means that we are saving just under 4000 $ annually. Our CO2 output is also much less. We are putting out approximately 10.3 metric tons less of CO2 gasses throughout the year

At the local Home Depot motion sensitive light switches are priced at 30$ after tax is 34 $

59 rooms = 34 X 59 = 2006 $ for all of the lights to be covered and installed. This is assuming we only need one sensor per room.

Even at an electrical savings of only 25% we basically cover our cost within the first year.

However if we save around 50%, we are then able to use the excess money to maybe move to something like Bullfrog power. An alternative energy company that may cost more but uses completely green energy from wind turbines and solar power.
