Energy Efficiency vs. Energy Intensity
Efficiency – amount of output per unit of energy Intensity – amount of energy per unit output
Terminology
Ene nerg rgy y Perfor
- rmance
mance Indi ndicat ators s (EnPls) – a measure of energy intensity used to gauge effectiveness of your energy management efforts. Basel elini ning - comparing plant or process performance over time, relative to its measured performance in a specific (i.e. baseline) year. Benc nchmar hmarking king - comparing performance to average or established best practice level of performance against an appropriate peer group.
Energy Use Drivers
Production Volume Weather Building occupancy Square feet
Simple Regression Model
Base Load Variable Load Energy Driver (e.g. Production Volume) Energy Use y = mx + b m = energy per variable unit b = base load R2 = correlation coefficient
EnPI Example – Data Collection
- Select baseline year
(e.g. 2008)
- 24 months additional
data
- Ensure data intervals
align
EnPI Example – Scatter Diagram
- Energy use is
dependent variable (y)
- Production is
independent variable (x)
- Relationship
appears linear
EnPI Example – Trend Line
- Slope (m) 0.3265
- Y-Int (b) 258,591
- R2 coefficient
- 0.8418
EnPI Example – Interpreting the Results
- Slope (m) - every Lb of extruded material requires 0.3265 kWh of
electrical energy (Energy Intensity)
- Y-intercept (b) – monthly electrical energy consumption unrelated to
production is 258,591 kWh
- R2 coefficient – approximately 84% of the variation in monthly
electrical energy consumption is explained by regression equation (i.e. “m” and “b”)
EnPI Example – Baselining Performance
- Goal: improve energy performance by 10% in 2 years
Year Variabl ble kWh Base e loa
- ad kW
kWh 2008 (Year 0) 0.3677 227,483 2009 (Year 1) 0.2524 323,603 2010 (Year 2) 0.2830 294,009 3-Year Value 0.3265 258,591 2-Year change Better by 30% Worse by 30%
Curious results needing investigation
EnPI Example – Applying the Results
For 2012, management forecasts a 15% increase in production over the 2010 volume of 10,200,000 lbs. What is the expected monthly electrical cost?
- 10,200,000 + 15% = 11,730,000 ÷ 12 = 977,500 lb per month
- (0.3265 kWh/Lb x 977,500 Lb) + 258,748 kWh = 577,902
- At $0.075 per kWh x 577,902 kWh = $43,343
What is electricity cost embedded in each extruded Lb?
- $43,343 ÷ 977,500 = 4.4¢
EnPI Example – Reporting the Results
- EnPIs, as indicators of performance, should be at the core of
your communication efforts.
- Communicating energy efforts and performance is vital for
generating awareness, responsibility & action
- Effective energy management involves changing organizational
culture and individual mindsets
Complicating Factors
( Indicated by Lower R2 ~<0.75 )
- More than one consumption driver of an energy source
– e.g. weather and production for natural gas
- Multiple or changing product mixture
– e.g. Output of one product dependent on another
- Production output not easily characterized
– Consider either product count, weight or volume – Look at production inputs (i.e. raw materials) instead of
- utputs
- Major system upgrades or change in operations
– Evaluate if baseline year EnPI values are still suitable
