An analysis of ACS' electrical consumption from 2015-2021

2015–2016

Fig 1a

Total cost for electricity was 763,006.18 aed

We pay 20 fils/kilowatts per hour (kwh). This means a total of 3,815,030.9 kwh was produced this school year

September was the most energy consuming month, accumulating 13.2% (100, 602.4 aed) of the total electrical expenditure of the year.

Fig 1b

January was the least energy consuming month, with 3.7% (28,220.8 aed) of the total electrical expenditure of the year. In 2016, Ramadan started on June 5.

Fig 1c The school gym was the most energy consuming building on campus (37.1% = 1,415,929.55 kwh). The new Elementary school building had the least energy consumption on campus (1.4% = 54,561.6 kwh). However, the building only opened officially in March towards the end of the school year.

2016-2017

Fig 2a

Total cost for electricity was 811,053.73 aed

We pay 20 fils/kilowatts per hour (kwh). This means a total of 4,055,268.65 kwh was produced this school year

Fig 2b September was the most energy consuming month, accumulating 12.4% (100, 378.2 aed) of the total electrical expenditure of the year. January was the least energy consuming month, with 4.8% (38,789.45 aed) of the total electrical expenditure of the year. In 2017, Ramadan started on May 26.

Fig 2c The school gym was the most energy consuming building on campus (39.9% = 1,617,942.3 kwh). The MS/HS building had the least energy consumption on campus (2.3% = 94,796.75 kwh).

2017–2018

Fig 3a

Total cost for electricity was 979,709.84 aed We pay 20 fils/kilowatts per hour (kwh). This means a total of 4,898,549.2 kwh was produced this school year

Fig 3b September was the most energy consuming month, accumulating 11.6% (111,766.2 aed) of the total electrical expenditure of the year. January was the least energy consuming month, with 5.2% (51,280.37 aed) of the total electrical expenditure of the year. In 2018, Ramadan started on May 16. Additionally, a new 5% VAT implemented starting 2017.

Fig 3c

The school gym was the most energy consuming building on campus (40.2% = 1,968,577.15 kwh). The MS/HS building had the least energy consumption on campus (2.3% = 114,806.2 kwh).

2018–2019

Fig 4a

Total cost for electricity was 983137.76 aed We pay 20 fils/kilowatts per hour (kwh). This means a total of 4,915,688.8 kwh was produced this school year

Fig 4b

November was the most energy consuming month, accumulating 12.7% (125,178.14 aed) of the total electrical expenditure of the year. January was the least energy consuming month, with 4.6% (45,524.64 aed) of the total electrical expenditure of the year. In 2019, Ramadan started on May 5.

Fig 4c The school gym was the most energy consuming building on campus (37.2% = 1,828,963.3 kwh). The MS/HS building had the least energy consumption on campus (2.3% = 113,982.55 kwh).

2019–2020

Fig 5a

Total cost for electricity was 873,505.71 aed We pay 20 fils/kilowatts per hour (kwh). This means a total of 4,367,528.55 kwh was produced this school year August was the most energy consuming month, accumulating 13.5 % (117,819.66 aed) of the total electrical expenditure of the year. April was the least energy consuming month, with 4.4% (38,394.93 aed) of the total electrical expenditure of the year. March 2020, ACS campus was shut down for the rest of the school year as a result of Covid-19.

Fig 5c

The school gym was the most energy consuming building on campus (37.7% = 1,644,521.55 kwh). The MS building had the least energy consumption on campus (2.1% = 91,777.35 kwh).

2020–2021

Fig 6a

Total cost for electricity is 467,137.23 aed (so far) We pay 20 fils/kilowatts per hour (kwh). This means a total of 2,335,686.15 kwh was produced as of now.

Fig 6b

August is the most energy consuming month so far, accumulating 19.4 % (90,662.88) aed) of the total electrical expenditure of the year. December was the least energy consuming month so far, with 5.9% (27,473.04 aed) of the total electrical expenditure of the year as of now. The 2020-2021 school year has integrated a hybrid schedule of remote and on campus learning.

Fig 6c

The school gym is the most energy consuming building on campus (32.6% = 760,461.45 kwh). The MS building had the least energy consumption on campus (2.1% = 48,808.2 kwh).

Overview Fig 7a There are many factors that can be indicated as possible reasons behind commonalities in the data. The impact of Covid-19 has been especially significant on ACS' energy consumption. Despite evidence of an upward trend in the data, remote learning has resulted in the decrease in campus energy expenditure.

Fig 7b

The months of August till October are usually account for the most energy consumed on campus, as a result of the weather and dependence on AC units in classrooms. In the data, the months of Ramadan have coincided with hotter months, hence it can't yet be determined whether Ramadan marks the increase in energy consumption at school.

Fig 7c

Larger and newer buildings like the School Gym and Elementary School building consume the most amount of energy, as opposed to older ones in the Middle School and High School. Additionally, it is worth noting the significance in energy consumption as proportional to the population a building sustains – a possible explanation for why the Middle School buildings tend to consume the least amount of energy.
