Introduction: Why Digital Twins Matter in Heat Networks

The complexity of modern heat networks requires more than just line drawings and estimates. As networks grow in scale and interact with other infrastructure, the risk of inefficiencies, delays, or design conflicts increases.

This is where digital twins come in — offering a way to visualise, test, and optimise a network long before construction begins. At DTS, we integrate digital twin thinking into every stage of our design process.

What Is a Digital Twin?

schematic-of-digitla-twin-integration-for-district-heating-design

A digital twin is a dynamic, digital replica of a physical system — in this case, a heat network.

It includes:

  • 3D geometry and layout (from BIM or CAD models)

  • Metadata on flow, temperature, and material performance

  • Integration with controls, zoning, and energy centre logic

  • The ability to simulate performance or test scenarios before build

Why Digital Twins Are Useful in Heat Network Design

Clash Detection & Routing
Avoid utility conflicts and unbuildable routes by simulating trench layouts, clearances, and elevation changes in 3D.

Thermal Performance Modelling
Assess heat losses, temperature drop, and flow dynamics across the system to optimise efficiency and insulation levels.

Design Coordination
Overlay with architectural, structural, and M&E models to ensure the heat network integrates with the wider project.

Smart System Testing
Evaluate control sequences, load profiles, and operational settings virtually — reducing commissioning risks.

Client & Stakeholder Visualisation
Use the model to explain design choices, zoning, and phases to non-technical audiences (e.g. planning teams, funders, councils).

DTS Capabilities in Digital Twin Modelling

CAD + Revit Integration
Our designs are built in 3D from the outset — enabling seamless transition to digital twin simulation.

Layered Data Mapping
We incorporate flow rates, pipe types, insulation values, and control logic into the model.

Smart System Logic Embedding
We simulate how heat pumps, pumps, and control systems will behave across various operating conditions.

Simulation-Ready Outputs
We provide models suitable for LCA, energy modelling, and commissioning tools.

FAQ

Do I need a full digital twin for a small network? +
Not always — but 3D modelling and clash detection are valuable even on modest schemes.
Can DTS supply BIM-ready outputs? +
Yes — we deliver in Revit, IFC, or 3D CAD formats depending on the client’s or contractor’s needs.
Is a digital twin just a 3D model? +
No — it also includes metadata and performance logic that simulate how the system behaves in real life.
What’s the return on investment? +
Fewer design errors, faster approvals, easier installation, and better long-term optimisation — all of which reduce risk and cost.

When to Use a Digital Twin

  • RIBA Stage 3–4: for network layout validation and technical design

  • Tender & procurement: to reduce queries and show buildability

  • Commissioning phase: to simulate controls and phasing

  • Long-term asset management: to support performance tracking and fault diagnosis
