Full-scale environmental simulation, from a single drawing.
The easiest way for architectural designers to access professional-grade simulation. “Will the air conditioning actually work?” “What will the energy costs be?” Leave complex setup to AI and instantly complete thermal, airflow, and energy analyses. Put environmental performance your clients can trust in your own hands.
For architects concerned about environmental performance
Ensuring energy efficiency and comfort is becoming essential in architectural design. Yet it remains difficult for designers to answer everyday questions such as “Will the air conditioning really work?” and “What will the energy costs be?” on the spot.
Performance becomes a barrier to design
I want to design double-height spaces and large openings, but I am not sure the air conditioning will work.
I want to find the limit for reducing costs without sacrificing performance.
Quantitative persuasion is difficult
When asked, “How much will changing the glazing reduce energy costs?” I can respond only with intuition.
I want stronger proposals for client discussions, competitions, and subsidy applications.
Specialist software is too difficult
Existing simulation software is difficult to operate, and I do not have time to learn it.
Too many input conditions are still undecided, so the work stalls. I need an easier way to get an initial estimate.
Solution
No specialist knowledge. No tedious setup.Montelo transforms your design process from the ground up.
Step 01
Upload the drawingsyou already use
Simply upload your usual drawings in PDF, CAD, or BIM format. AI interprets your design intent and automatically builds an analysis-ready model. You can begin your analysis right away.
Step 02
Tell the AI what you need Get the answers right away
You can quickly answer questions such as “How much will switching the window glazing reduce energy costs?” and “Will this room layout create uneven temperatures?” by testing as many design options as needed from the earliest stages—from annual energy consumption to temperature distribution and airflow—and gain solid evidence for environmental performance.
Step 03
Combine intuition with data,and make every design proposal more compelling
Annual energy use, temperature variations, and other results are presented in clear visuals. You can explain why a design works with quantitative data—not intuition alone. Identify the best balance of design intent, cost, and performance for yourself.

The name "Montelo" comes from the Greek word that, like the English "Model," means a "model" or a "scale model." In architectural design, model-making is the act of giving a thought-form a physical presence — testing the soundness of a design while bringing it closer to reality. It is the most primitive and essential way to keep an idea from staying an idea, and to give it shape so it can be examined.
Montelo carries that role into the digital realm. It exists to verify design proposals through simulation, and to send ideas — that would otherwise have stayed as pure imagination — toward implementation, with solid evidence.
