MEP Desk is a desktop application built for mechanical, electrical, and public health engineers — the people who design and specify building services systems. If you work in consulting or contracting and spend your days switching between spreadsheets, PDFs, emails, and disconnected calculation tools, MEP Desk is designed to replace that fragmented workflow with a single, structured workspace.
The daily pain points
Building services engineering hasn't kept up with the tools available to other disciplines. Structural engineers have FEA software. Architects have BIM platforms. MEP engineers, in many practices, still rely on a patchwork of general-purpose tools that weren't designed for engineering workflow.
Here's what that typically looks like:
- Spreadsheets that break or lose context. Calculation spreadsheets get passed between team members, edited without version control, and often lose the assumptions that justified the original inputs. A pipe sizing sheet tells you the result, but not which room it was for or which design standard was referenced.
- PDFs of standards that are hard to search. British Standards, CIBSE guides, and manufacturer datasheets are essential references, but finding a specific table or value means scrolling through long documents. There's no quick way to search across multiple sources at once.
- No single place to track project assumptions. Assumptions about design temperatures, air change rates, diversity factors, and material properties are scattered across emails, meeting minutes, and spreadsheet headers. When a value changes, there's no reliable way to see which calculations it affects.
- Exports require manual formatting. Producing a calculation summary for a client report means copying results from spreadsheets, formatting them in Word or Excel, and manually checking that inputs match the latest project data. It's slow, repetitive, and prone to error.
How MEP Desk solves each one
Calculations with built-in room context. MEP Desk calculators aren't standalone — they connect to your project structure. When you have an active room selected, the calculator suggests relevant inputs based on the space type and any project-level assumptions you've set. Inputs are traceable: you can see which values were manual and which came from defaults.
A searchable reference library. The built-in reference library gives you instant access to pipe sizes, thermal properties, ventilation guidance, material data, and more. Everything is searchable and structured in tables you can filter and browse — without leaving the application or opening a separate PDF viewer.
A project system with rooms, assumptions, and health tracking. Projects in MEP Desk are organised around rooms and engineering disciplines. You set project-level assumptions across six disciplines — mechanical, electrical, public health, fire, acoustics, and sustainability — and those assumptions feed directly into your calculators. The project health dashboard shows which rooms are complete, which have missing data, and where attention is needed.
One-click export with selectable categories. When you're ready to produce documentation, MEP Desk lets you preview exactly what will be exported, select which calculation categories to include, and generate a clean output. Every result traces back to its inputs and source references. No manual formatting required.
What MEP Desk is not
MEP Desk is not a BIM tool. It doesn't produce 3D models or integrate with Revit geometry. It's not a drawing tool — it won't generate schematics or layouts. And it doesn't replace engineering judgement. Every calculation requires user input and verification. The software assists documentation and traceability; it does not automate design decisions.
MEP Desk is for the working engineer who needs a faster, more structured way to handle the daily tasks that currently live across too many disconnected tools. If that sounds like your workflow, it's worth trying.
