Electrical
Preliminary residential lift count, round trip time, handling capacity and connected electrical load. Final lift data must be coordinated with the selected manufacturer.
Speed and occupancy varied around the selected case
Average connected load: 51.0 kW Median: 50.3 kW 90th percentile: 71.2 kW Selected case percentile: 40.7%
Use this graph to judge whether the selected lift bank connected load is typical or conservative when rated speed and served occupancy move around the current design case. The red marker shows the current input case against the sensitivity range.
Floors and speed varied around the selected case
Average RTT: 163.1 s Median: 159.8 s 90th percentile: 202.5 s Selected case percentile: 49.2%
Use this graph to see how sensitive the round trip time is to building height and lift speed. A higher selected-case percentile means the current assumptions produce a slower cycle than most nearby scenarios.
Occupancy varied across a preliminary design range
Average handling capacity achieved: 8.63 % Median: 8.48 % 90th percentile: 9.68 % Selected case percentile: 11.8%
Use this graph to confirm whether the lift count and car capacity provide enough five-minute handling capacity across a range of occupancies. The selected marker shows the achieved handling-capacity percentage for the current population.
