Create a New Project

Click + New Project on the MEP Engine page. Fill in your building details โ€” or just type a description and let AI extract the parameters automatically.

  • Title: Give your project a name (e.g. "Villa Al-Nakheel โ€” Jeddah")
  • Description: Describe in Arabic or English โ€” AI fills the fields automatically
  • Building Type: Residential Villa / Apartment / Office
  • Floors: Any number โ€” buildings above 10 floors trigger high-rise mode
  • Area: Total built-up area in mยฒ
  • City: Search from 59 cities across 31 countries (ASHRAE climate data)
  • Special Rooms: Toggle chips for spaces like Majlis, Gym, Pool, Server Room, Prayer Room, etc. โ€” this applies to the whole building, not a specific floor, and affects electrical/plumbing sizing for those spaces
Tip: For Arabic input, type "ููŠู„ุง 3 ุบุฑู ู†ูˆู… 350ู… ุฏูˆุฑูŠู† ุฌุฏุฉ" and AI will extract all parameters automatically.
Special Rooms are whole-building, not per-floor: Selecting "Gym" or "Server Room" tells the engine your building contains that space somewhere โ€” it doesn't ask which floor. The generation engine allocates appropriate electrical/plumbing capacity for it, but placement on a specific floor isn't something you configure here.

Generate Electrical System

Click โ–ถ Regenerate to calculate the complete electrical system per SBC 401. This auto-generates plumbing and HVAC at the same time.

โ–ถ Regenerate

The Summary panel shows:

  • MDB Rating โ€” main distribution board ampere rating
  • kVA Demand โ€” total connected and demand loads
  • Circuits โ€” number of branch circuits generated
  • Demand Saved โ€” demand factor reduction from SBC 401-220.42
  • Rooms / Phase Imbalance โ€” room count and 3-phase balance
Wire sizing: All conductors sized per SBC 401 Table 310 with altitude derating for high-altitude cities (Abha 2270m, Taif 1880m, etc.)

Generate Additional Disciplines

Use the header buttons to generate fire protection, high-rise systems, and elevator calculations:

๐Ÿ“ Floor Plan ๐Ÿ”ฅ Fire ๐Ÿ—๏ธ High-Rise ๐Ÿ›— Elevator
๐Ÿ“
Floor Plan
SBC 101 โ€” Architectural floor plans with rooms, doors, windows, dimensions
๐Ÿ”ฅ
Fire Protection
SBC 801 / NFPA โ€” Sprinklers, detectors, extinguishers, exit signs
๐Ÿ—๏ธ
High-Rise (>10 floors)
Transformer, generator, chiller plant, wet riser, refuge floors, piles
๐Ÿ›—
Elevator (>4 floors)
SASO 3493 / EN 81 โ€” Passenger, service, firefighter lifts
High-rise mode automatically activates for buildings above 10 floors โ€” adds transformer sizing, chiller plant, pressure zones, wet riser, refuge floors and pile foundation.

Review Results

Use the tabs on the right panel to review calculations:

Summary ๐Ÿ“– Learn ๐ŸŽ“ Quiz ๐Ÿ  3D
  • Summary: MDB rating, demand, circuits, phase balance
  • Learn tab: Every calculation explained step by step with SBC rule citations โ€” e.g. "Wire sized at 4mmยฒ because load = 2800VA continuous ร— 1.25 รท 230V = 15.2A โ†’ 4mmยฒ XLPE (rated 24A, derated to 17.5A) per SBC 401 Table 310"
  • Quiz tab: 25 questions generated from your project โ€” test your SBC knowledge
  • 3D tab: Isometric building visualization โ€” drag to rotate, scroll to zoom
AI Editing: Click any element in the Learn tab and type a natural language instruction โ€” "increase load by 20%" or "upgrade to 6mmยฒ wire" โ€” AI applies the change and checks SBC compliance.
