• apply_ifc_rules ~988 tokens
  Turn what you read in the overview into rules the tool replays on EVERY piece of the model, including the ones you were never shown. NOT NEEDED ON A MODEL ALREADY TREATED: when read_ifc_overview returns 'designation_existante', the units and fans are already designated - reuse them. Posting rules R
• check_en378_zones ~1348 tokens
  DETERMINISTIC: the same inputs always give the same result — from any AI, on any day. Figures come from the standard's tables and formulas, never from a language model's estimate. Every step is auditable. EN 378 applied to BUILDING projects, volume by volume. An installation does not occupy one ro

  DETERMINISTIC: the same inputs always give the same result — from any AI, on any day. Figures come from the regulation's annexes and thresholds, never from a language model's estimate. Every step is auditable. Swiss refrigerant regulation check (ORRChim / ChemRRV annex 2.10, OFEV synthesis of May 2
• ifc_upload_result ~108 tokens
  Where the upload stands. When `state` is `depose`, `token` is the token to pass to read_ifc_networks.
• name_ifc_networks ~479 tokens
  Apply the names you propose, and get back the updated report. THE NAMES ARE YOURS, THE NETWORKS ARE NOT. You are naming what the tool measured; you are not changing what it measured. Nothing you send here alters a network, a part, or a correction. WHAT COMES BACK. The updated report, a 3D link whe
• open_ifc_upload Sends messages · ~233 tokens
  Show an upload box in the conversation where the user can drop an IFC file (.ifc) of a building services model (HVAC, plumbing, heating). The file goes straight from the user's browser to thenewengineer.com - you never see it. CALL THIS when the user wants to analyse an IFC model and has not yet gi

  DETERMINISTIC: networks come from geometry, not from a guess. The same model always gives the same networks, from any AI, on any day. Read the networks of an IFC model already uploaded by the user. WHAT A NETWORK IS. A set of parts that touch each other, cut at equipment: a pump, an air handling u
• read_ifc_overview ~671 tokens
  CALL THIS FIRST, as soon as the user gives you a token - a link thenewengineer.com/ia/XXXX pasted in the conversation - BEFORE you answer anything, even when the user only says they will choose or do something themselves. It answers within seconds, while the network graph is still being built - use

  THE CIRCUITS THE FANS OF A MODEL ARE SIZED ON, found without anyone clicking and computed on the pressure-drop page, where the user confirms types and flows and reads the pressure drops.
