Practical steps Collect at least three years of utility date To identify a historical energy use pattern Identify the fuel types used Electricity, natural gas, oil etc Determine the fuel type that accounts for the largest energy use Determine the pattern of fuel use by fuel type Identify the peak demand for energy use by fuel type Understand utility rate structure (energy and demand rates) Peak demands and if cheaper fuel can be purchase Analyze the effect of weather on fuel consumption Perform utility energy use analysis by building type and size To compare against typical indices
