Notes on building services, BIM and turning building codes into software.

  1. Building an HVAC SaaS Platform on My OwnHow I went from Excel-based HVAC calculations to building Mepbau — a cloud platform with 7 DIN-standard modules — as a solo founder with a day job.
  2. Building Revit Add-ins for MEP Engineers: Automating What Shouldn't Be ManualA practical guide to why and how MEP engineers should automate repetitive Revit tasks — from duct tagging to data export to batch parameter updates.
  3. From DIN Standards to API Endpoints: Encoding HVAC Calculations for the WebHow I translated DIN EN 12831 heating load calculations and VDI 2078 cooling load standards into a web-based calculation engine — the approach, the challenges, and the patterns.
  4. IFC vs Proprietary Formats: Why Open BIM Will Win (Eventually)After 3+ years of BIM coordination with proprietary and open formats, here's why IFC adoption is inevitable — and what's still blocking it.
  5. Parsing IFC Files for the Web: A Developer's Guide to Open BIM DataIFC is the open standard for BIM data exchange. Here's how to extract MEP system data from IFC files and serve it through a web API — concepts, tools, and practical use cases.
  6. The HVAC Industry's Software Problem — And Why Engineers Are Building Their Own ToolsThe AEC/MEP industry relies on fragmented, desktop-bound tools from the 1990s. A firsthand look at why mechanical engineers are picking up code editors.
