An energy audit is an inspection, survey and analysis of energy flows for energy conservation in a building, process plant or system to reduce the amount of energy input into the system without negatively affecting the output(s). In commercial and industrial real estate, an energy audit is the first step in identifying opportunities to reduce energy expenditure and carbon footprints.
The term energy audit is commonly used to describe a broad spectrum of energy studies which can be bifurcated in to principally three types as under:
Preliminary Energy Audit
To establish energy consumption, Estimation of scope for energy saving, Prioritization of area of energy improvement, Identify immediate energy saving potential, Setting up of base line reference and identification of area of detailed study.
Targeted Energy Audit
Based on Preliminary Audit targeted Audit will be for detailed analysis to achieve targeted energy efficiency.
Detailed Energy Audit - A comprehensive Audit
Detailed study of energy consumption, Analysis of energy consumption, Recommendations for reduction of energy consumption with cost benefit calculations and project implementation recommendations.
The Audit also will include monitoring the implementation of the recommendation and achievement of final goals in respect of energy reduction.
