Specific Energy Consumption

Targets & Benchmarks Benchmark is the desired or targeted consumption of energy or specific energy consumption. The benchmark values are set based on Theoretical Calculations Specifications by equipment / plant supplier Best achieved in the same plant Best achieved in the similar industry.

Specific Power Consumption for Office Premises Case Study : 343 kWh/M2/Year Wipro :190 kWh/M2/Year ITC :125 kWh/M2/Year CII :70 kWh/M2/Year

Energy Accounting & Un-accounted Consumption Prepare break up of consumption for each form of Resources energy by Computing consumption of the respective area / equipment. Noting down operating period. Take data from various sub-meters Compare total consumption as estimated above with actual consumption to ascertain “Unaccounted” or “Miscellaneous” portion of the consumption Analyze consumption pattern

Energy Accounting / Balancing

Equipment Performance Compute performance of all the equipments by measuring Actual Output Flow, pressure, refrigeration effect, FAD, etc. Specific Energy Consumption kWh/TR, CFM/kWh, Steam to fuel ratio Efficiency Pump, boiler, thermopac

Performance of the Machines

Specific Power Consumption : AC

Norms: Specific Output - Air Compressor

Distribution System Heat Loss – Hot Insulation, Surface Evaporation Heat Ingress – Cold Insulation, Openings in AC area Leakages – Compressed Air, Thermic Fluid Pressure Drop – Pumping Systems, Compressed Air Power Loss – Electrical Systems & Cabling Determine the best close for your audience and your presentation.
