55 Though approximate, annual operating energy (i.e. with doors or car moving) could be: 30,000 travels/year for a 350 kg hydraulic with 6 m travel (210 kWh); 50,000 for 480 kg electric with 12 m (190 kWh); 80,000 for 630 kg electric with 20 m (680 kWh). Stand-by (per UNI/TS 113006): 1.27 kWh/day (463 kWh/year) for the first; 2.27 kWh/ day (828 kWh/year) for the others. Totals: 673 kWh, 1,018 kWh, 1,508 kWh—for systems without energy recovery and hydraulic without oil heaters. LIFT’S REAL IMPACT ON BUILDING CONSUMPTION These figures aren’t exact, but lifts typically account for under 3% of total building energy, so minor inaccuracies in the installer’s report have negligible effect on the overall technical report required by the decree. Indeed, a recent Northern Italy Class A building may need 30 kWh/m²/year, up to 150 kWh/m² for a typical older Class D. For a 1,000 m² office building (three 330 m² floors), a 630 kg hydraulic lift with 25,000 annual travels impacts 0.73 kWh/m² (2.4% of Class A total, 0.49% of Class D). An electric lift impact would be 0.89 kWh/m², slightly higher. Taller buildings may see even lower relative impact due to fixed stand-by spread over more building area. * General Director Koppel A.W. 50% COUNTERWEIGHTED ELECTRIC LIFT, GEARLESS WITH INVERTER: ENERGY NEEDS IN WH Portata/corsa 6 m 12 m 15 m 20 m 350 kg 1,4 2,7 3,4 4,5 480 kg 1,9 3,8 4,8 6,4 630 kg 2,5 5 6,4 8,5 TABLE 1 HYDRAULIC LIFT (INVERTED TROUGH, NO OIL HEATING RESISTORS): ENERGY NEEDS IN WH Portata/corsa 6 m 9 m 12 m 350 kg 7 10,5 15,7 480 kg 8,2 12,3 18,5 630 kg 10,7 16,1 24,3 TABLE 2 LIFTING PLATFORM (INVERTED TROUGH, NO OIL HEATING RESISTORS): ENERGY NEEDS IN WH Portata/corsa 6 m Hydraulic 6 m Electric 350 kg 6 1,2 TABLE 3
