. It is widely used by architects and urban planners to analyze how design choices—like building placement, vegetation, and materials—affect local environmental conditions like wind flow and temperature. 1. Getting Started
| Limitation | Explanation | |------------|-------------| | | High-resolution 3D simulation of 24 hours can take 24–72 hours on a standard workstation. | | Steep learning curve | Requires understanding of urban climatology, CFD principles, and model parameter choices. | | Limited indoor-outdoor coupling | Buildings are usually treated as isothermal or with simplified indoor setpoints (unless using external BEM coupling). | | No dynamic traffic or moving sources | Pollutant sources are static (line or area sources). No moving vehicles. | | Idealized lower boundary | No large-scale topography (hills) beyond grid-scale slopes. | | No precipitation or snow | Hydrological processes limited to evaporation and soil moisture; no rain interception or snowmelt. | Envi-met Software
Envi-met treats buildings as multi-layer systems. It simulates heat transmission through walls and roofs, indoor temperatures, and the release of waste heat from air conditioning or heating systems back into the outdoor environment. | | No dynamic traffic or moving sources
ENVI-met has evolved into a suite of integrated tools: Envi-met Software
