Transforming drawings into intelligent, compliant building energy models with AI.
How NexBEM Works
1️⃣ Upload Drawings or BIM
Start with architectural PDFs, floor plans, or BIM files NexBEM reads the design details, project metadata, and site information automatically - we get your pain
2️⃣ AI Geometry Parsing
Our computer vision and graph models detect walls, floors, roofs, windows, and zones creating a 3D model aligned with simulation requirements - no more wrestling with softwares
3️⃣ Model Input Assembly
NexBEM populates envelope constructions, schedules, and space types using rule-based templates, design defaults, or extracted data - zone assignment made easy
4️⃣ System & Schedule Mapping
The platform identifies HVAC system types, ventilation rates, and control strategies, then links them with internal loads, occupancy, and operation schedules - system assignment in a sec
5️⃣ QA & Validation
Automated QA checks geometry, all the inputs and maps the changes, NexBEM flags missing inputs and validates assumptions before simulation - quicker reviews and change management
6️⃣ Simulation & Compliance
Generate baseline models for the standards and codes NexBEM produces compliance ready outputs and summary reports - move on to your proposed design
AI for Better Building Energy Modeling
NexBEM AI is an applied artificial intelligence company focused on advancing the building energy modeling industry. We develop intelligent automation that streamlines geometry creation, input data handling, QA, and compliance analysis helping professionals focus on design decisions and performance insights rather than repetitive modeling tasks.
Our mission is to accelerate high performance building design by making high-quality, code-compliant energy models faster, more consistent, and accessible.
