Zenesis

Web-based early-phase MEP/TGA planning platform that combines BIM data, firm-specific rulebooks, and AI to standardize technical decisions before modeling begins

Zenesis is an independent, web-based planning platform for technical building equipment (TGA/MEP) engineering firms that structures and validates technical decisions during the earliest project phases — offer, feasibility study, and HOAI service phases 1-2 — by combining BIM data, a firm's own standards/rulebooks, and AI into what the vendor calls a continuous decision layer, exchanging data with Graphisoft Archicad via dedicated add-ons rather than operating inside Archicad itself.

WHY IT EXISTS

Why This Tool Exists

The Problem

MEP/TGA (technical building equipment) engineering firms in Germany historically make and re-justify technical decisions manually and inconsistently across the earliest project phases — offers, feasibility studies, and HOAI Leistungsphasen 1-2 — before BIM modeling even starts, leading to repeated rework each time a design iterates.

The Solution

Zenesis is a standalone, web-based planning layer that structures early-phase MEP/TGA decisions by combining BIM data, a firm's own standards and rulebooks, and AI, and exchanges data with Graphisoft Archicad through dedicated add-ons (Zenesis operates independently of Archicad rather than as a plugin inside it). The vendor reports up to 70% planning-time reduction and roughly 40 hours saved per design iteration for customer firms, and data import/export in under 15 minutes.

Exactly what this tool uses and how

Input
What it needs
Required:BIM data, Firm-specific standards/rulebooks
Optional:Prior-project data for import (< 15 minutes per vendor claim)
Formats:BIM data import, Archicad data exchange via add-on
Output
What you get
