2. Why Managing Energy Consumption?
Energy is the largest cost for maintaining
a buildings and
manufacturing environmental footprint
Energy efficiency provides
financial returns

3. Benefits of Energy Consumption Management
Reduce utility bills
Improve profits
Improve processes
Reduce emissions
Reduce risk to energy price fluctuations

4. Steps for Energy Consumption Management
Create a corporate culture of continuous improvement in energy efficiency
Establish an awareness program at all levels with energy management
Create a verified record of energy intensity/efficiency improvement.

5. Energy Review Identify significant energy users and relevant variables
HVAC system
Lighting
Compressor
Furness/oven
Boiler
Motors
