1. Preface The purpose of this preface is to serve as a brief note to future students and readers of this report about its inception, its vision and its cause. The idea of performing an energy audit IIT Kanpur was introduced to the founder members of GE3 by an alumnus of IIT Kanpur. In the beginning the task of carrying out a full scale survey of IIT Kanpur seemed daunting. Thus, it was decided to carry out an energy audit of only the student hostels. The present report is a result of culmination of a thought that occurred three years ago to some students who formed GE3 in the summer term of 2008. This is the third report in the series of the energy reports by GE3. The first energy audit report was made for the year 200809 and it was the first major contribution of the group after its formation. Similar report was also made for the 200910 which served as a benchmark for the present report. This document has a dual purpose to serve as a result of Green Opus for Galaxy 2010 and also to inform the campus residents about our hostel energy usage so that we can improve our way of living and increase our energy efficiency. Our vision is to instill a sense of responsibility towards our environment in the future professionals that pass through the gates of IIT Kanpur. We make this effort to create a generation of engineers and scientists who are aware about ecology, environment, effect of our activities on them and the ways that we can effectively and scientifically minimize our ecological footprint. We hope our efforts inspire the reader to lead an energy efficient lifestyle at IIT Kanpur and beyond, which usually does not take more than switching off that tubelight, fan or heater when you leave the room. With hope. Anand Vardhan Mishra Coordinator GE3 20092011

2. Description of Methdology Energy Consumption from corresponding months were compared as follows: Four months were considered: October, November, December and January. Base Month
2009, October
2009, November
2009, December
2010, January
Current Month
2010, October
2010, October
2010, December
2011. January
Percentage Change was calculated by subtracting the average “Base Month” energy usage from the average “Current Month” usage and dividing it by average Base Month's usage and multiplying by 100. Hall 10 was not included in the calculations as the base month data was not available for it.

Points were awarded to each hall for each month. The Performance Indicator used to gauage the performance of a Hall was its percentage change. The more negative percentage change was desirable as it indicates a rise in energy efficiency. Sample Percentage Change in per capita energy consumption for September in various halls

Thus we can see in this sample month Hall 4 finishes first as it has the most negative percentage change in average power consumption, followed by Hall 9 and then Hall 5. Hall 6 (GH2) however shows the most positive percentage change in average energy consumption thus finishes last. Points were awarded as follows: 25, 20, 15, 10 , 8 , 6, 5, 4, 3, 2. according to the rank.

Average Reduction per student in four months = 50 units Average Reduction per Student per month = 12.575 units Total Reduction from hostels = 171880 Units ➢ On an average the (total sum) consumption of a student in IIT Kanpur reduced by approximately 50 units from October 2010 to January 2011 this year when compared to the same period in the previous year 2010. ➢ Total reduction achieved was 171880 units for four months averageing out to 42970 units per month. This is equivalent to savings of INR 150,000 per month for four months.

6. Suggestions 1. Pareo's law states that 80% of our problems are are caused by 20 % of our problems. We can see that during the four months we consume the most (~40%) in January. Thus we should concentrate our efforts in limiting energy usage in January. 2. Similarly energy usage in Hall 6 (GH2) should be reassessed to make the energy consumption more efficient there. Other halls that can be concentrated upon are Hall 7 and Hall 8.
