Optimizing a building's thermal comfort using CFD analysis: the benefits deciphered
CFD simulation is a powerful tool used in fluid mechanics to analyze and predict fluid flows.
It is widely used to optimize the thermal performance of buildings and improve the thermal comfort of occupants. CFD is used to model in detail the phenomena of thermal convection, thermal radiation and heat transfer inside a building.
Sophisticated simulation software makes it possible to take into account the various parameters influencing thermal comfort, such as air ducts, radiators, windows, etc.

By simulating the behavior of fluids and heat transfer within a building, it is possible tooptimize energy efficiency and adjust heating, ventilation and air-conditioning systems to maximize thermal comfort for occupants.
For example, it is possible to determine the best layout for radiators or the optimal placement of air ducts to ensure even heat distribution.
CFD also makes it possible to analyze the impact of various factors on thermal comfort, such as the presence of draughts, temperature variations in different areas of the building, or the effects of sun exposure.
Thanks to this information, informed decisions can be made to improve thermal comfort for occupants and reduce energy bills.
How can CFD simulation be used to improve thermal comfort?
Once the CFD tests have been carried out and the building’s main thermal issues identified, EOLIOS is able to provide various technical solutions to remedy them and optimize the building’s thermal comfort, focusing on the following points:
- Thermal insulation: Ensure that the building is well insulated to minimize heat loss in winter and prevent overheating in summer.
Insulating walls, attics, floors and windows can significantly reduce heating and cooling requirements. - Solar control: Use low-emissivity glazing and solar shading to limit excessive heat gain from the sun.
Blinds, shutters or solar films can also be effective in reducing solar gain in summer. - Effective ventilation: Ensure that the building has an adequate ventilation system, capable of providing fresh air circulation and good indoor air quality.
Correct ventilation helps maintain comfortable temperature and humidity levels, while avoiding condensation problems. - Optimizing heating and air-conditioning systems: Choose efficient heating and air-conditioning systems adapted to the building’s needs, so as to achieve comfortable temperatures at appropriate times, while avoiding unnecessary energy wastage.
- Humidity management: Control humidity inside the building to avoid condensation and mold problems by implementing adequate ventilation solutions to maintain a comfortable humidity level.
The solutions we propose are customized and unique to each situation, taking into account the customer’s needs, technical and economic constraints, and the full range of physical phenomena at play in the environment under study.

Why use CFD to improve thermal comfort?
What parameters are taken into account in the simulations?
When EOLIOS carries out a CFD simulation to study the thermal comfort of a building, many parameters are taken into account.
Firstly, CFD simulation models take into account the geometry and characteristics of the entire building, which will be accurately modeled in 3D, as well as air ducts and ventilation systems.
The simulations then take into account heat exchange between the building’s various components, such as walls, windows, floors and radiators, to model heat transfer and calculate temperature variations inside the building. Thermal radiation is also taken into account, making it possible to analyze the impact of solar radiation through windows and determine whether solar protection measures are necessary to avoid overheating.

External weather conditions, such as temperature, relative humidity and wind speed, are also taken into account to assess their impact on heat exchange between the building and the external environment. These meteorological conditions are accurately determined by studying records from nearby weather stations, and in particular local annual maximum and minimum temperatures are used to ensure pleasant thermal conditions in both winter and summer, while avoiding unnecessary energy expenditure.
The thermal properties of building materials, such as thermal conductivity and thermal capacity, are also taken into account to accurately model heat transfer through the various building walls.
Finally, CFD simulations can take into account the presence and activities of occupants, enabling us to assess the impact of their presence on temperature and air circulation, in order to optimize thermal comfort conditions inside the building.
Why are EOLIOS CFD simulations different?
Our studies do not impose fixed boundary conditions on the outside of the model.
In this case, for example when studying glazing, surface temperatures will depend on the various convective exchanges.
In addition, this allows us to approximate real conditions of temperature distribution at any point in the room.
In practice, CFD simulations are carried out to confirm that the calculated indoor environment meets requirements.
If the CFD modeling shows a deviation from the required values, the design solutions are corrected to eliminate or limit the deviations identified.
In this case, CFD modeling is compared and repeated until satisfactory results are obtained.
