We support you with CFD simulation, energy building and fire simulation.
Maximize comfort. Minimize costs. Guarantee safety.
Many consider CFD simulation a luxury. Our experience from over 150 projects shows the opposite. Every client was ultimately grateful for having simulated. Designs were validated, errors detected early, and costly remedial work avoided.
The attitude “We prefer to build before the simulation shows that the design doesn’t work” is no longer sustainable in times of scarce resources and rising construction costs. Simulation is not a cost center. It provides planning reliability and especially saves operating costs.

« Simulation doesn’t have to be expensive. »
As a specialized engineering firm for building simulation, we advise architects, developers and planners on the energy and airflow optimization of their projects. With over 15 years of experience and more than 150 projects worldwide, we combine scientific precision with practical consulting.
CFD analyses for optimal indoor airflow, ventilation and thermal comfort in buildings.
Learn more →Energy assessment and optimization of the building envelope for maximum energy efficiency.
Learn more →Simulate smoke and heat propagation for safe escape and rescue route planning.
Learn more →Precise on-site measurements and airflow visualization with fog machines for simulation validation.
Learn more →Contact us directly for a non-binding consultation.
From the initial inquiry to the finished result: transparent and efficient.
We analyze your project, define the simulation objectives and create a tailored proposal: free of charge and non-binding.
Based on your planning documents, we create the 3D simulation model using state-of-the-art tools such as OpenFOAM, EnergyPlus or FDS.
We perform the simulation: whether airflow, thermal, daylight or fire. Precise results through validated calculation methods.
You receive a detailed simulation report with visualizations, recommendations for action and concrete optimization suggestions.
Upon request, we accompany you through to implementation: with on-site follow-up measurements and continuous consulting during the construction phase.

Updates from TIAN Building Engineering and insights from our international projects.
We have once again successfully trained engineers and students at Taylor's University in practical CFD and green building simulation.
Through hands-on exercises with FlowSIM Pro and OpenFOAM, participants connected fundamental knowledge with real simulation workflows. Thank you to Taylor's University and everyone who took part for their strong interest and active exchange.
We successfully convinced another university of how important CFD and Green Building Simulation will be for the future of building design.
Welcome, Thai Nguyen University. Together we are strengthening education, knowledge transfer and practical simulation workflows for sustainable buildings.
TIAN Building Engineering and Taylor University are entering into a partnership to connect research, education and practical applications in Green Building Simulation more closely.
The collaboration focuses on energy-efficient buildings, indoor air quality, thermal comfort and simulation-driven planning for sustainable building projects.
