Project Switch Off: Progress Report

Project Switch Off

For Project Switch Off, assessment of its implementation will be via:

1) Survey of number of lecture rooms with lights and A/C left on at the end of the day

2) Weekly electric meter readings

3) Monthly electricity bills


One week prior to implementation of the project we patrolled to check each of the lecture rooms in SST after 4 pm from Monday through Friday (24 Aug – 28 Aug 2009). The survey was carried out after 4pm because based on the schedule there should not be anymore classes after 4 pm unless there are replacement classes or other special arrangements. This is to assess the current conditions pre-implementation of the project – whether students are switching off the lights and air-conditioner after their last lecture of the day which ends at 4 pm in SST. This is important information because after 4 pm if a room is empty with its lights and air-conditioner on, chances are they will be on the entire night through the next morning unless another student(s) goes in to switch them off. As mentioned in the Project Switch Off page, no security guard or technician would go around switching off everything at the end of the day. It is entirely the students’ responsibility to switch off everything before they leave the lecture rooms because students are the only people to use them.

Results from this survey showed that throughout the normal week:

The average number of rooms with lights on after 4.42 pm*  was 7 (range 3 – 13)

The average number of rooms with air-conditioner on after 4.42 pm* was 14 (range 11 – 19)

The sample size was out of 30 frequently used lecture rooms including:

Bilik Tutorial : 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 28, 29, 30, 37, 38, 41,

42,45, 46, 47, 48, 49, 50, 51, 52

Bilik Kuliah : 2, 3, 4 (Bilik Kuliah 1 uses centralized air-conditioner)

*The time is 4.42 pm because 4.42 pm is the average time of sampling throughout the week (Monday 24 Aug – Friday 28 Aug 2009) .

To have an average of 14 lecture rooms over a week with their respective air-conditioners potentially blasting away throughout the night on any given day is some serious amount of wastage we are talking about here. This is however only the preliminary survey. We shall see how the number fluctuates as we begin implementing the project.

Weekly Electric Meter Readings

Since 19 August 2009 (Wed), we have been recording the electric meter reading at SST consistently on Wednesdays 12 pm. Below are the results to date:

The rate is fixed at RM 0.25/kWh (Commercial Class II Rate)

The rate is fixed at RM 0.25/kWh (Commercial Class II Rate)

Based on the meter readings so far, the amount of electricity used in SST varies rather significantly even by the week. Keeping in mind that this project was supposed to begin implementation from 1st September 2009, the current results are an indication that things are not going too well. Nevertheless, it is just the beginning. Three weeks of electricity consumption data is still too small a sample size to prove anything. It is also important to note that the project is just in its early stages. We are still in the process of getting the students in SST onboard, much less the lecturers and the rest of SST’s community. Progress is slow but a small number of courses have begun practicing the habit of responsible electricity use, which is a good thing. We will continue to work on the behavioral change and keep everyone updated about how SST is doing with its electricity consumption over time. All things to do with human habit and behaviour  takes time. The ultimate goal is to create the sense of importance within each individual to take action on their own accord. At the end of the day, even if we only achieved an insignificant amount of savings, as long as we managed to change the habit of a small group of people, the project has served its purpose. Nothing will be in vain.

We’ll keep you updated over time as we record the weekly electric meter readings.

Information on the Monthly Electricity Bills will be up as soon as we are done with all the data compilation work.
