The En Trak system was installed over the February 4-5 weekend to track energy usage at the school. The data can be accessed from the school wifi and is displayed intuitively using units like pineapple buns. In March, the first month of En Trak, the average energy used was 2,715 kilowatts per hour with the most used on March 6th equivalent to 8.2 taxi rides to Xiamen. In March 2012 the school spent around $515.7 per hour on energy and the goal is to reduce usage by 5%.
