Look up every field and KPI — what it means, what it changes, and how the analytical check relates to DES. Keep it open beside the simulator while you size a project.
Open the guideLift traffic analysis FAQ
- How many lifts (elevators) does an office need?
- There is no fixed car count. Size the group so 5-minute handling capacity and interval meet ISO 8100-32 Table 2 for the building type, then check the result with simulation. Run a free up-peak analysis in the simulator with your floors, population, and car data.
- What is ISO 8100-32 up-peak analysis?
- ISO 8100-32:2020 Annex D is the planning method for up-peak lift traffic: round-trip time, interval, and handling capacity from building and lift data. Elevator Dynamics Engine runs that analytical check in the browser.
- What is 5-minute handling capacity?
- Handling capacity (HC%) is the share of building population the lift group can serve in five minutes. Offices typically target around 12% with a short interval; hotels and residential buildings use different Table 2 bands.
- What is CIBSE Guide D used for in lift design?
- CIBSE Guide D waiting-time bands rate passenger service (average waiting time). Use them alongside ISO handling-capacity and interval checks — the simulator reports both.
- Is this software ISO- or CIBSE-certified?
- No. Methods follow ISO 8100-32:2020 and CIBSE Guide D waiting-time bands. It is analysis software, not a certified or endorsed ISO/CIBSE product. A qualified lift traffic engineer still owns the design judgement.
- When will Pro subscriptions be available?
- Pro — DES simulation, ISO PDF export, advanced workspace, and cloud projects — is launching soon. Join the waitlist on the pricing page with your email. The free analytical simulator is available now.
