A high night time energy use factor indicated that night perimeter lights have a big impact in overall energy use. Using our intervention calculation tools, a 120KWh Energy Savings per day revealed, when replacing existing luminaires with new high efficiency LED luminaires. Actual savings were measured at 130kwh/day. With the cost at 3.000€, a payback time of 15 months came out. The same action for Interior lights to be replaced with LED, resulted to savings of 350 kWh/day, a cost of 20.000€ and a payback time of 36 months.
Profiling analysis revealed a periodicity of high energy consumptions during afternoon hours. We performed rescheduling of the charging time of the forklifts after 23:00, when the tariff is lower cost. The savings related to this exceeded the 100€ in the first 4 months.
