Analysis of real-time electricity consumption in Canadian school
The study entailed analyzing real-time electricity consumption in classrooms, gymnasiums and spaces believed to be heavily used by the community in those three schools.
View DetailsSchool buildings contribute considerably to overall energy consumption due to their large number within the building stock . They represent an excellent opportunity towards improving energy efficiency as they “can be used as communication means towards pupils and their families, and can thus reach many different society groups” .
The new school's classroom, on the other hand, consumed on average 8.74 Wh/m 2 /day for plug loads and 11.55 Wh/m 2 /day for lighting. These results indicate that classrooms may not be contributing to new schools' increased electricity consumption. Fig. 3. Daily electricity consumption for classroom (a) Lights and (b) Plug Loads.
Real-time total school electricity consumption was also obtained by downloading data from the advanced utility meters available in two of the schools. For the third school without an advanced utility meter, real-time electricity consumption in the school main cable was monitored using a DENT ® ElitePro XC meter.
The post-hoc pair-wise comparisons also showed statistically significant differences in electricity consumption for lighting and plug loads during work and non-work hours between all pairs of classrooms, except for lighting between the old and new schools' classrooms during non-work hours.

Like many large buildings, schools suck lots of energy from the grid to keep lights on, halls warm and students comfortable, translating to high bills for school districts. However, a case study

The data is self-reported and has been filtered to exclude outliers, buildings with less than a full year of consumption data, cases that are used for testing purposes and an additional filter was applied.
