AVR&SVR COLLEGE OF ENGINEERING &TECHNOLOGYDIPLOMA EEE (2013-16) ELECTRICAL AND ELECTRONICS ENGINEERING Abstract: An energy audit is a study of a plant or facility to maximum execution of the recommendations and the success of this work. determine how and where energy is used and to identify methods for energy savings. There is now a universal recognition of the fact that new technologies and much greater use of some that already exist provide the most hopeful prospects for the future. The opportunities lie in the use of existing renewable energy technologies, greater efforts at energy efficiency and the dissemination of these technologies and options. This energy audit of the Avr&Svr college area was carried out by us. This report is just one step, a mere mile marker towards our destination of achieving energy efficiency and we would like to emphasize that an energy audit is a continuous process. We have compiled a list of possible actions to conserve and efficiently utilize our scarce resources and identified their savings potential. The next step would be to prioritize their implementation. We look forward with optimism that the institute authorities, staff and students shall ensure the I. INTRODUCTION This Ppt is the vision to make our campus energy efficient. It is a fact that our college community uses a huge amount of energy and it is also very obvious that we waste quite a sizable chunk of it. Our college bill keeps up around INR 9, 60,000 per year. This amount is huge and thus naturally attracts attention when we understand that quite a lot of energy is being wasted, which in turn would mean that huge amount of financial resources are being wasted. II. AVR&SVR COLLEGE: PRESENT ENERGY SCENE Avr&Svr College has an approximate area of 6 acres with student community strength of around 3000 and about 200 faculty. There is a floating population of the order of 500 in the campus as the residents enjoy the right of way through the campus. Avr&Svr College enjoys 24 hour electricity supply while within a few hundred feet Walk-through audit.27KW 16. QUANTIFICATION BY END USED: The loads were segregated based on the end use as lighting and fans.98. Avr&Svr college has a demand of 200KW (APSPDCL data). The walkthrough audit provides an initial estimate of potential savings and generates a menu of inexpensive savings options usually involving incremental improvements in O&M.of the institute there are 12 hour power cuts. water pumping. including a visual inspection of each of the associated systems. The best way to determine the appropriate type of audit is to look at the Energy Use Index (EUI) of the facility or building involved (see Appendix A). Historic energy usage data are reviewed to analyze patterns of energy use and Connected Electrical Load compare them with sector/industry averages or Distribution (In KW) TUBELIGHTS FANS 40.4KW benchmarks for similar structures. 1.
