How do you optimize the operation of multiple passenger elevators in a building?

Alright, let’s cut to the chase — if you’re running a building with multiple passenger elevators, you know the struggle: guests waiting 10+ seconds on a busy floor, deliveries getting stuck in elevator bays, that one guy who always calls the elevator to go down from the 2nd floor when it’s already swamped with 12th floor folks. As a passenger elevator supplier, I’ve spent years working with property managers to fix these messy, inefficient headaches — and it’s not just about selling you new tech. It’s about smart, real-world tweaks that make your elevators work for you, not against you. Here’s what actually moves the needle. Passenger Elevator

First off, let’s talk about how most buildings mess up elevator operations right out the gate. A lot of old-school systems use a “call and wait” setup — someone presses a button, and the nearest (but not always the smartest) elevator trundles over. For small to mid-sized buildings, that might work, but if you’ve got 4+ elevators in a 15+ story building? That’s a recipe for wasted trips. Last year, I worked with a 20-story apartment building downtown that was running 6 elevators 24/7, but their wait times averaged 18 minutes during rush hour. Why? They weren’t grouping elevators by “zones” — top floors all shared one elevator cluster, mid floors another, ground floor only for lobby traffic. So when a bunch of people on the 18th floor pushed up, the system might send an elevator from the 2nd floor that was already on its way down, instead of the cluster sitting idle on the 17th. Zone grouping is the simplest, most impactful fix. We retrofitted their existing system to split the floors into three zones: low (1–7), mid (8–14), high (15–20). Rush hour got a tiny boost to split the high zone into two (15–17, 18–20) so peak demand didn’t swamp that end. Their wait times dropped to 7 minutes overnight — no new hardware, just a programming tweak.

But wait, zones aren’t one-size-fits-all. What if your building has a medical wing on the 3rd floor, or a food court on the 5th that gets crazy busy at lunch? That’s where destination dispatch systems (DDS) come in — and no, you don’t have to replace every elevator to add them. A lot of property managers think DDS is only for fancy office towers, but modern units are modular. DDS works by having you tap your floor before you step into the elevator — the system crunches real-time data to assign you to the best car. For example, if 10 people tap floor 10 at noon, it’ll send one elevator loaded with 8 of them, not spread them across two cars and leaving half empty. I recently did a project for a mixed-use building with a grocery store on the ground floor and a gym on the 2nd — the DDS we installed adjusted dynamically: every weekday at 11 AM, it parked an extra elevator near the ground floor to handle grocery shoppers, and at 6 PM, it shifted that same elevator to the 2nd for gym goers. We pulled data from their building’s access control system to time it, so it wasn’t guesswork. No more waiting 5 minutes for an elevator just to grab a banana.

Then there’s the stuff people overlook: maintenance scheduling. I know, it sounds boring, but here’s the thing — a broken elevator is a useless elevator. Last quarter, a client of ours had 3 elevators out of service for 2 days because they waited until something major broke, instead of doing proactive checks. The resulting chaos? Employees bailing early, residents complaining to the city, and the property manager on the hook for fines. As a supplier, we’ve built predictive maintenance features into our latest systems that use sensors to track elevator performance — like how often the door opens/closes, how smooth the ride is, even how much weight each car is carrying. We got an email alert at 2 AM from a system that noticed one elevator’s door was taking 2 extra seconds to close on 10 consecutive trips. Our techs swapped a worn rubber seal the next morning, no service disruption, no emergency callout fee. The old way was reactive — “if it breaks, fix it.” The new way is “track every tiny sign of wear and fix it before it becomes a problem.” For multi-elevator buildings, this is non-negotiable. If one goes down, the whole system gets overloaded — so keeping all 2 (or 5, or 8) in working order is half the optimization battle.

Another big one: handling special requests. Every building has them. A moving truck needing an entire elevator for furniture. A wheelchair user needing extra time. A meeting that starts in 5 minutes on the 12th floor, so you need an elevator parked there early. A lot of basic systems don’t prioritize these requests. We worked with a corporate HQ that has weekly executive meetings — we added a “priority call” feature that’s tied to their calendar. When a meeting starts, the system sends an elevator to the 12th floor 10 minutes early, locks it so no one else can call it, and keeps it there until the meeting ends. No more executives showing up late because the elevator was stuck on the 5th for a group of interns. We also have a disabled access mode that slows door closing times by 5 seconds and keeps the car parked longer if a wheelchair is detected, which we integrated with the building’s accessibility team so they don’t have to manually adjust it every time.

Wait, let’s talk about peak hours specifically — because that’s when 80% of the complaints happen. Most buildings only have morning and evening rush, but mixed-use buildings have lunch, mid-day, and end-of-day peaks too. Here’s a trick we use: adjust elevator capacity during peaks. If you have elevators that max out at 20 people, during lunch, the system can cap it at 18, but during morning rush (people going up to work), cap it at 22 — that small buffer cuts down on overcrowding, which means doors don’t get stuck, so the system doesn’t fall behind. We also tested something called “elevator parking” during off-peak hours. For a building that’s mostly empty on weekends, we park 2 elevators near the lobby and 1 near the top floor, instead of all spread out. When a call comes in, the system sends the closest one, but not one that’s just sitting idly — so you’re not wasting energy moving an elevator 15 floors just to pick up one person. It’s a tiny energy saving, but it adds up, and it makes wait times faster too.

Don’t sleep on data, either. A lot of property managers I talk to don’t look at their elevator data — they just go by what people say. But the numbers don’t lie. For example, one apartment building thought their 2nd floor was always busy, but the data showed the 6th floor had 3x more calls at 7:30 PM, because that’s where the gym is. So we adjusted the zone for the 6th floor to pull an extra elevator car during that time, and wait times went from 12 minutes to 5. We also found that some buildings have “ghost calls” — people pressing the elevator button and walking away, which clogs the system. The DDS can detect if a call isn’t matched to a floor input, so it cancels it automatically, which cuts down on unnecessary trips.

Now, I know what some of you are thinking: “This sounds expensive.” But here’s the thing — you don’t have to rip out all your old elevators. Most of the optimizations we do are retrofits, not replacements. We worked with a 1980s office building with 4 elevators that were 30 years old, and instead of selling them new ones, we installed a mid-tier destination dispatch system, added predictive maintenance sensors, and tweaked the zone programming. They saved over $100k in elevator replacement costs, and their wait times dropped by 60%. For small buildings, even a basic zone setup and scheduled maintenance can make a huge difference. For larger towers, adding the DDS and data tracking is worth the investment because it cuts down on downtime and keeps tenants happy.

At the end of the day, optimizing multiple elevators is all about being smart about how you move people, not just how many elevators you have. It’s about using the tech that’s available now, not clinging to the way things were done 20 years ago, and paying attention to both the big peaks and the tiny, daily quirks that cause frustration.

If your building is dealing with slow elevators, high wait times, or constant downtime, we can help. We don’t do one-size-fits-all solutions — we’ll audit your current system, look at your usage data, and put together a plan that fits your building, your budget, and your tenants’ needs. Whether you need a simple programming tweak or a full retrofit with the latest tech, we’re here to make your elevators work for you, not against you.
