OZU is a compliance engine that embeds directly into Revit and ArchiCAD to check building models against UK and Portuguese Building Regulations in real time. The tool delivers deterministic, auditable pass/fail verdicts for every element—from door widths to U-values—with each result traced to its specific clause and measured value. Currently in private beta, OZU runs the entire rule set simultaneously, flagging failures with the exact fix required.

Problem
Architects and designers must manually verify building models against complex, evolving regulatory codes, a process that is time-consuming, error-prone, and often discovered late in the design cycle. Traditional compliance checking relies on subjective interpretation and fragmented tools, leading to costly rework, project delays, and risk of non-compliance.
Solution
OZU embeds directly inside Revit and ArchiCAD, providing real-time compliance checking against the entire rule set as the model is being designed. The engine analyzes every element—doors, corridors, stairs, glazing, thermal performance—and returns deterministic pass, fail, or incomplete verdicts in seconds. Each result is traced to its specific regulatory clause and measured value, giving architects a clear audit trail and the exact fix needed for any failure. When a fix is applied, the rule re-runs instantly, enabling iterative design resolution without leaving the modeling environment. OZU currently supports UK and Portuguese rule packs, with a live scan interface that visualizes all rules running at once across the model.
Target Audience
Primary users are architects, building designers, and compliance consultants working in Revit or ArchiCAD who need to ensure their models meet UK and Portuguese Building Regulations throughout the design process.
Features
- Real-time compliance scanning embedded natively within Revit and ArchiCAD, eliminating the need for external checking tools
- Deterministic verdicts with zero false PASS—every result is traced to its specific regulatory clause and measured value
- Comprehensive rule coverage including RGEU (Portugal) and Approved Documents (UK) for accessibility, fire safety, ventilation, thermal performance, and means of escape
- Instant re-checking of individual rules when a fix is applied, supporting iterative design workflows
- Visual dashboard showing pass, fail, incomplete, and review statuses across all rules simultaneously
- Data-missing detection that flags incomplete model information, such as awaiting fire door data or unconfirmed travel distances
