6.4. Electricity consumption of Escalators and Moving Walks in Europe According to <strong>ELA</strong> statistics, there are 75.000 escalators and moving walks installed in the EU‐ 27. Based on the surveys conducted in WP2, two assumptions are made: • 75% of the escalators are installed in commercial buildings and the remaining 25% in public transportation facilities. • 30% are equipped with a Variable Speed Drive (VSD) Based on the measurements conducted in WP3, the average value for the electricity consumed during running and standby modes (slow‐speed and stopped), is considered. Table 6‐5. Average electricity consumption in each operating mode Escalator 1 2 3 4 5 6 7 Average Active Energy‐Running, 5 minutes test (Ecr) [Wh] Active Energy‐Standby in a LOW SPEED mode, 5 minutes test (Ecsl) [Wh] Active Power ‐ Standby in a STOP mode (Pss) [W] 162,1 186,37 127,34 172,58 131,18 166,31 164,55 158,6 n.a. 82,42 n.a. 80,87 44,54 n.a. n.a. 69,3 53,3 43,53 30,73 50 16,87 38,84 40,93 39,2 Only escalators in commercial buildings were monitored. Based on <strong>ELA</strong> experts’ opinion, it is considered that escalators in public transportation facilities consume 75% more electricity than escalators in commercial buildings. The time spent in each operating mode is assumed as shown in the next table. Table 6‐6. Time spent in each operating mode Escalators without VSD Escalators with VSD Commercial Public Transportation Commercial Public Transportation Running (h) 4368 7280 1872 2912 Slow‐speed (h) 0 0 2496 4368 Stopped (h) 4392 1480 4392 1480 The energy consumed annually is calculated using the Methodology defined in WP3 (Chapter 5) and shown in Table 6‐7.

6.5. Estimation of Savings Potential ‐ escalators and moving walks For the estimation of energy savings it is considered that all of the escalators installed would be equipped with VSD. Furthermore, it is considered that when stopped, the controller and inverter only consume one Watt each. Table 6‐8. Estimated escalator electricity consumption using best available technologies. With inverter Total Commercial Public Transportation Buildings Erunning (GWh) 217 196 EStandby (GWh) 117 119 649 GWh A potential reduction in the electricity consumption of around 255 GWh (28%) would be possible and it would mean a reduction of 100.000 ton per year in CO 2eq emissions. 87
