Elevator / Vertical Transportation Sizing
How many passenger lifts a building needs, from a traffic analysis of the busiest period: the morning arrival peak. It checks both how many people the lifts move in five minutes and how long people wait.
- The round trip time of one car.
- Each car's five-minute handling capacity.
- The number of lifts needed to meet the target handling capacity.
- The number needed to keep the waiting interval under target.
- Follows: CIBSE Guide D, transportation systems in buildings; Strakosch, The Vertical Transportation Handbook.
- This sizes passenger lifts for the arrival peak. Service lifts, fire lifts and buildings with a strong lunch or departure peak need their own analysis.
