Spaces

Spaces are MEP-specific spatial elements in Revit. They are similar to Rooms but belong to the MEP model and carry mechanical, electrical, and plumbing analysis data.

The Space object

{
  "id": 318204,
  "type": "Space",
  "name": "Office",
  "parent": null,
  "values": {
    "number": "1.01",
    "level": "01 eerste verdieping",
    "area": 24.5
  }
}

The field structure is identical to Rooms. The difference is in how they are used in Revit and what data they carry for engineering analysis.

Room vs Space

	Room	Space
Object type	Room	Space
Created in	Architecture model	MEP model
Used for	Space management, area schedules	HVAC zones, MEP analysis
Requires	Room-bounding elements	Room-bounding elements + linked arch model

In DAQS rules, use type = "Room" for architectural space validation and type = "Space" for MEP space validation. Never combine them in a single filter unless the rule explicitly applies to both.

Basic filter

$[type = "Space"].{
  "id": id,
  "type": type,
  "name": name,
  "number": values.number,
  "level": values.level
}

---

Duplicate number detection

Same pattern as Rooms — see Rooms for the full example. Replace type = "Room" with type = "Space".

Common mistakes

• Confusing Room and Space — they are separate types and must be filtered separately
• Expecting Spaces to exist in an architecture-only model — Spaces are only created in MEP models
