Energy Efficiency Reference/Industrial/General Assessment Concepts

• Preparation
• Utility Cost Analysis
  • Energy usage trends:
    • heating and cooling loads - seasonally dependent
    • process loads - production dependent
    • fixed loads - base load
    • unusual changes
  • Rate structure interpretation - kW draw and kWh consumption
  • Incremental costs - projected energy costs
• Energy Balance
  • End use breakdown
  • Do system models fit with annual records?
• Mass Balance
• Collecting Data
  • Anecdotal
  • Observation
  • Measurement
  • Estimation
    • Includes consulting plant personnel
• "Making do with" (leveraging) available data
• First Estimates (SWAGs)
• Red Flags
• Rules of Thumb
• Seeing the Big Picture
• A Critical Mind
• Analysis
  • Understanding the level of analysis you are planning / able to do
