Where we look
Connect vehicles, buildings and infrastructure into one improvement plan.
Zerith combines energy data, operational context and engineering review to identify measures that improve efficiency without obstructing service delivery.
Fleet baselines
Fleet energy and fuel-performance baselines
Establish a useful baseline across vehicle groups and operating conditions so performance can be understood in context.
The question: how does energy use change by duty, route and vehicle?CONNECTED SYSTEM VIEWILLUSTRATIVE
The aim is a prioritised programme of low-risk operational improvements, planned upgrades and longer-term investment decisions.
Transportation and Logistics Systems solutions
Specialist expertise matched to the decisions you need to make.
Engineering, energy intelligence and investment support for transport systems where service continuity matters.
Energy and compliance

ZECO estate intelligence
Create one performance view across fleet and fixed assets.
ZECO brings energy, operational and engineering information into one structured view, helping teams move from reporting to prioritised action.
- Benchmark vehicles, routes, depots and stations using relevant operating variables.
- Identify idling, out-of-hours demand, charging peaks and underperforming assets.
- Prioritise interventions across fleet, buildings and infrastructure.
- Reuse verified information across compliance, investment and decarbonisation planning.
ZECO supports analysis and prioritisation; it does not replace engineering review or guarantee savings.

Frequently asked questions
Clear answers for complex transport systems.
Can you assess both vehicles and fixed sites?
Yes. The scope can combine fleet or rail energy with depots, stations, warehouses, workshops and associated infrastructure.
Can you support EV charging and capacity planning?
Yes. Zerith can review demand profiles, diversity, maximum demand, electrical capacity, charging strategy and investment phasing.
How do you compare different routes or vehicle types?
Performance can be normalised using distance, payload, duty cycle, operating hours, vehicle type and other relevant variables.
Can recommendations protect service reliability?
Yes. Availability, maintenance, operating windows and resilience are treated as core design constraints.
Do you support fleet decarbonisation roadmaps?
Yes. Roadmaps can coordinate vehicle replacement, infrastructure, energy supply, operational change, cost, carbon and programme risk.
