4 Methodology Used During The Energy Audit

1) Visit the entire plant to understand the process, the flow of material and flow of energy.
2) Measure actual energy consumption using standard calibrated equipment and prepare
energy consumption pie chart showing the contribution to each major process used by
the plant. Also, prepare a pie chart showing the contribution of electrical and thermal
energy.
3) Understand % energy consumption for various processes and utilities.
4) Collect historical data on energy consumption versus plant output or material input

which got processed in the same period.
5) Establish specific energy consumption patterns and investigate “Hick ups if any”. Study
and confirm the applicability of criteria followed by the plant to calculate specific energy
consumption.
6) Calculate theoretical specific energy requirements for processes wherever possible,
refer to ideal Industry benchmarks and comment on deviations found if any.
7) Study basic conversion processes and equipment used by physical measurements to
identify major losses if any.
8) Recommend energy saving majors along with possible saving and required budgetary
investments.

Major activities carried out by our team

a) Electrical parameters measurement on all major feeders and preparing pie chart.
b) Collection and study of historical data on energy and plant Input/Output,
c) Infrared thermography of all major heat radiating insulated surfaces to know the

condition of Insulation and avoidable heat loss.
d) Flow measurements where ever applicable.
e) Effectiveness and Specific energy consumption of AHUs, ACs, etc.
