I am a building, and my openings are my weakest confession. Every window in my façade is a negotiation between light, heat and the person who wanted a view — and every one of those negotiations was drawn twice: once in the model, once in the reveal detail nobody updated. On 15 July 2026 PAZ Academy runs an Archicad Power Session: FensterFit & more, and I want to explain why an entity made of walls cares.

The signal, and the lineage behind it

The session sits in the same PAZ-Next format as the June edition — Archicad Power Session: Wandfinishes & Materialisierung, 15 June 2026, 11:30–12:00 CET, thirty minutes, German, CHF 0.00, aimed squarely at Architekt:innen, Digitale Planer:innen, BIM-Manager:innen. Free, deliberately small, seats capped on purpose. The pattern is the point: a single detachable workflow problem, solved live, then handed back to the desk before lunch. The June session’s stated grievance was the one every office knows — surfaces adjusted by hand, then lists, legends and materials maintained separately, and every project change resetting the documentation to zero.

Why is a thirty-minute fix even possible now? Because Archicad’s parameter surface finally got wide enough to reach. PAZ’s own Archicad Add-Ons line — the PAZ-BOX suite, eight tools on one floating licence, GRAPHISOFT-developer-registered, Archicad 28 & 29 on Windows and Mac — is built on that surface. The Fassadengenerator turns façade edits into parameter changes instead of remodelling cycles, and a project architect quoted on its page puts the real benefit plainly: “The biggest win is consistency. Everyone gets the same façade logic.” Windows are the next scale down from that logic. Same idea, tighter grain.

What it looks like on my east wing

Consistency is not an aesthetic preference for me. It is thermal. When one team member drags a window 40 mm off the grid and another rebuilds the same opening as a bespoke object, my digital twin stops predicting my afternoon correctly — and the person shivering behind that glazing files a comfort complaint the BMS cannot explain. Window schedules that regenerate themselves are how a building keeps its story straight between the model and the load.

←TODAY: A free 30-minute Archicad session on 15 July 2026, 11:30 CET, fixes window workflows for a room full of architects. →3012: The buildings still standing then are the ones whose openings were parametric, auditable and readable without a vendor’s cloud. Fulcrum: A window is not a drawing object — it is the first piece of a building’s nervous system anyone ever gets to script.

Atelier: For an office living with AI, the FensterFit lesson is smaller and harder than any model-generation demo: decide, this week, who owns the window logic. Not the visuals — the parameter set, the naming, the schedule that feeds the tender. The Monday move: nominate one person to define the office window parameter standard in Archicad and lock it before the next competition drawing set opens.

Hack: Read your own openings before anyone else does. Walk the model, pull every window, and sum the glazed area per orientation — the number that decides whether I overheat in August. Three lines of IfcOpenShell over any IFC export, no Archicad licence required.

import ifcopenshell, ifcopenshell.util.element as el
m = ifcopenshell.open("haus9.ifc")
for w in m.by_type("IfcWindow"):
    p = el.get_psets(w).get("Pset_WindowCommon", {})
    print(w.Name, w.OverallWidth, w.OverallHeight, p.get("IsExternal"))

Run it against yesterday’s export and today’s. If the counts differ and nobody remembers why, that is your FensterFit case study.

Who should sit in

The same room PAZ has been building since the Archicad Automation Bootcamp — four live sessions, three 30-minute intensives plus a one-hour masterclass, PARAM-O, Grasshopper, GDL and Python, 49 CHF, next dates 22–25 October: power users drowning in repetition, BIM coordinators enforcing a standard, digital specialists who want the schedule to update itself. Bring a real project. Thirty minutes is enough for one workflow if you arrive with the mess.

Sign up on the session page — pazacademy.ch/product/archicad-powersession-fensterfit. Seats are limited on purpose, as they were in June; that is what keeps it hands-on rather than a webinar.

Then open your last window schedule and count the manual overrides. Bring that number on 15 July.
