MRL vs Traditional Elevator – Total Cost of Ownership in Nigerian Commercial Buildings
The upfront price of an MRL is often 5‑15% higher than a traditional machine‑room elevator. But over 10 years, which is cheaper? We break down all costs – construction, energy, maintenance – to give you a real answer for Lagos, Abuja, and Port Harcourt buildings.

Construction Savings – The Machine Room Advantage
A traditional elevator needs a 10‑15 sqm machine room. At Lagos construction costs of about ₦150,000 per square metre, that room costs ₦1.5 million to ₦2.25 million to build. An MRL eliminates it entirely. This saving often offsets the higher equipment price of an MRL.
The machine room is not just a concrete box. You must build walls, a roof slab, a door, and a floor strong enough to hold the traction drive motor and control panels. A hard fact: According to EN 81‑20, the machine room floor must support a concentrated load of 6,000 Newtons per square metre for the motor base. That means thicker slab reinforcement. In a six‑storey commercial building on Broad Street, Lagos Island, the machine room added about 12 square metres of structural dead load. The MRL option removed that load. The structural engineer reduced column sizes on the top floor. That cut cost further.
Cooling is another hidden expense. A geared traction machine in a traditional lift generates heat. In Lagos, where afternoon temperatures reach 34°C, a machine room without ventilation will overheat. The controller can trip, causing sudden stoppages. You must add a split‑unit air conditioner or a forced‑air exhaust fan. An AC unit costs about ₦300,000 installed. It runs for 8‑12 hours daily, adding to the energy bill. An MRL system has its motor and controller inside the hoistway. The hoistway naturally drafts air as the car moves. We add a temperature sensor and a ventilation fan that kicks in at 40°C. The result is no separate cooling room and no AC electricity cost.
Waterproofing a rooftop machine room in coastal areas is a constant battle. In Lekki Phase 1, salt spray and heavy rains attack the machine room walls. We have repaired rusted machine bedplates in rooms that leaked. A machine room also needs a dedicated lightning rod and surge protection on the main feeder. In an MRL, the whole system sits inside the protected building envelope. The savings on waterproofing and surge protection add up. These construction and ancillary savings often cover the extra 5‑15% equipment cost of an MRL lift system before the building even opens.
Energy and Maintenance Over 10 Years
An MRL uses 30‑40% less energy than an old geared traction lift. Annual maintenance is slightly higher because the controller sits at the top of the hoistway. But the difference is small. Our 10‑year projection shows an MRL comes out ahead by ₦2 million to ₦4 million for a typical five‑stop office lift.
Energy is the biggest long‑term cost differentiator. A traditional geared machine uses an induction motor with a worm gearbox. The gearbox wastes energy as heat. An MRL uses a gearless permanent magnet synchronous motor. A hard fact: ISO 25745‑2 classifies lift energy performance. A gearless MRL typically achieves Class A or B. A geared traction lift often falls to Class D. In a busy Abuja commercial hub building with 50,000 trips per year, that efficiency difference can save ₦300,000 to ₦500,000 annually in electricity at current Band A tariffs. Over 10 years, that is ₦3 million to ₦5 million.
We also need to factor in generator runtime. During power outages, the generator supplies both the lift and the machine room AC. An MRL reduces the building’s peak load by eliminating that AC. The generator burns less diesel per hour. For a typical 60 kVA generator, the saving is about 1.5 litres of diesel per hour. In a building with two hours of daily outage, that is over 1,000 litres saved per year. Diesel in Lagos costs roughly ₦1,200 per litre. That adds another ₦1.2 million per year in fuel savings. This saving goes straight to the bottom line.
Maintenance costs for MRL are often misunderstood. Yes, the controller is mounted at the top of the hoistway, 4 to 5 metres high. Technicians need a ladder or an access platform. This adds 15 to 20 minutes to each monthly service visit. But the MRL has fewer wearing parts. There is no machine room sheave, no governor rope through multiple pulleys, and no gearbox oil to change. Our service records show that MRL call‑outs are 25% fewer than geared traction lifts in similar Lagos buildings. The cost of a permanent access platform is a one‑time ₦200,000, not a recurring cost. The net annual maintenance cost difference is under ₦100,000.
When we combine construction savings, energy savings, and diesel savings, and subtract the small maintenance difference, the MRL shows a clear advantage. For a five‑stop, 1,000 kg capacity lift in a Victoria Island office block, the 10‑year total cost of ownership favours the MRL by ₦2 million to ₦4 million.
