Background
Direct energy
Energy used in the process (mixing, shaping, proof, baking, cooling, etc.)
Indirect energy
Lighting, ventilation, office (computer, lighting, heating), cleaning
Energy used in supporting the process (Washing, compressed air, recycling)

Process
Which? When? How long? 7/24, Maintenance, season change
Energy drift, aging, fault, parts efficiencyUpgrading, retrofitting, maintenance
Is this the best way to do it? Are the settings optimal? Are you running it correctly?
