Building and Civil Engineering

Our involvement in building and civil engineering

Numerical simulation in building and civil engineering is widespread for the mechanical dimensioning of structures using finite element softwares. With the increasing reinforcement of energy constraints, thermal and fluid optimization is now becoming essential in the design process.

Our skills

The possibilities are numerous, among which:

Aerodynamic calculations (wind loading) around buildings

  • Forces calculation (pressure, drag and yaw) on the structure at any point.
  • Calculation of structures heat transfert coefficients to assess thermal exchanges that occur between inside and outside of building.
  • Calculation and assessment of areas with high wind speeds for discomfort estimation. Wind turbine location analysis.

Thermal comfort calculations, energy efficiency of a building

  • Building energy efficency  (summer, winters ..).

  • Thermal comfort calculations (ventilation, air conditioning..), with or without solar radiation.

  • Dynamic thermal simulations.

Hydraulic network balancing calculations

  • 2D pseudo modeling of a distribution network (pumps, valves, elbows ..). Flow rate calculations for minimum speed and minimum temperature requirements.

  • Column balancing calculations (sizing of pumps, pipes, insulators). Valve settings for balancing columns.

Examples of studies involving building and civil engineering
