Energy is usually the second largest controllable cost on a site, and the one least often measured properly. Before anything is switched off, it has to be understood.
Measure before you change anything
A month of honest metering will tell you more than a year of assumptions. Kitchens, laundries, accommodation and plant are read separately, because a single site total hides everything worth fixing.
The quiet hours cost the most
Equipment left running through the night rarely appears in anyone's budget line, yet it is often the single largest avoidable cost. Start-up and shut-down routines fix more than new equipment does.
- Written start-up and shut-down routine per area
- Extraction and refrigeration matched to service hours
- Planned maintenance so plant runs at rated efficiency
Maintenance is an energy strategy
Fouled coils, worn seals and untuned burners quietly add to consumption every hour they are ignored. A maintenance calendar that is actually followed will beat most capital projects on payback.
