INTRODUCTION
• Power, the word itself says to what extent the world is dependent on it.
• For sustainable development, we need to adopt energy efficiency measures.
• Today, 85% of primary energy comes from non-renewable and fossil sources (coal, oil, etc.). These reserves are continually diminishing with increasing consumption and will not exist for future generations
• Energy saving constitutes a primary measure for the protection of the environment.

NEED OF ENERGY AUDITS
• Minimizing energy wastage.• Finding out the areas where energy wastage
occurs• Optimizing energy efficiency with suitable
technology.• Using the most appropriate energy
resources
Energy Audit – an overview
• Identification of areas of energy wastage and estimation of energy saving potential.
• Suggesting cost effective measures to improve the efficiency of energy use.
• Estimation of implementation cost and payback periods for each recommended action.
• Documenting results and vital informations.
• Recommendation for better efficiencies. 3 phases of auditing1.Pre auditing phase2. Auditing phase3. Post auditing phase
Energy Audit Methodology• Data Collection – In preliminary data collection
phase, exhaustive data collection was performed using different tools such as observation, interviewing key persons, and measurements.
• Data Analysis - Detailed analysis of data collected in the primary stage. The data's thus analyzed is used for future works .
• Recommendation – On the basis of results of data analysis and observations, some steps for reducing power consumption without affecting the comfort and satisfaction will be recommended along with their cost analysis.
• Energy auditing survey.
• Analysis of the previous energy utility.
• Light energy utility survey
• Energy audit of inverter and battery.
• Substation auditing
• Thermal auditing.
ENERGY UTILITY SURVEY
• Total power consumption.
• Consumption pattern of different months.
• Equipment wise consumption pattern of overall campus.
• Variation of load factor and power factor.
• Comparison between connected load and maximum demand
LIGHT ENERGY UTILITY SURVEY.
• Lighting system and required illumination.
• Analysis of total power usage by lighting loads.
ENERGY AUDITING OF INVERTER AND BATTERY.
• Auditing of ups system.• Evaluation of backup of batteries
SUBSTATION AUDITING
• Evaluation of neutral current.
• Power quality analysis.
THERMAL ENERGY AUDITING.• Diesel log analysis.
• Comparison : rent bus and owned bus.
• Analyzing mileage of available buses.
Expected Schedule of work plan
Work Period of work(expected)
Energy utility survey 1st Oct- 30th Oct
Light energy auditing 17th Nov – 5th Dec
Substation auditing 25th Nov – 10th Dec
UPS auditing 20th Nov- 15th Dec
Thermal energy auditing 15th Nov- 15th Dec

CONCLUSIONo The next generation generating yet to come will be
completely light blind. It is because power never be available after this disaster and not ever rehabilitate the reconstruction of buildings. To avoid the energy calamity proposed auditing use the innovative energy utilization schemes through which the ferocious of situation might blindness can be eradicated
