The input for CFD analysis is derived from 2-D and 3-D CAD files and information from the design architect and engineers. To ensure computational efficiency, the space geometry must be simple to minimize computational cost (time) but accurate enough to represent the physics of the space. Boundary conditions must be defined in terms of ambient weather conditions (solar loading, wind pressure, temperature and humidity) and material thermal/physical properties.

The CFD model splits the space of interest into a finite number of volumetric elements in a process called "meshing". During the analysis, the software iteratively solves a set of simultaneous differential equations for continuity, energy and 3-D velocity until the solution converges. This process is called steady-state mode. Some problems cannot be solved in steady-state mode because of unstable air flow patterns, in which case transient analysis methods must be used.

CFD modeling represents a relatively new method for architects and engineers to assess and refine their design solutions. It provides the ability to confirm the required performance during the design phases, thus reducing the risk and liability of integrating innovative energy efficiency and sustainable design strategies into the project.

Architectural Energy Corporation air flow modeling staff are experts in applying advanced CFD modeling technologies to complex architectural and engineering design problems, and thus can help design teams move to the next level of advanced high performance building design.
