# Environmental Simulation for AEC Computational Design This skill provides a comprehensive reference for environmental performance simulation in the Architecture, Engineering, and Construction industry. It covers daylight analysis, solar radiation studies, energy modeling, computational fluid dynamics for wind, thermal comfort assessment, acoustic simulation, and the Ladybug Tools ecosystem that ties these workflows together within parametric design environments. --- ## 1. Performance-Driven Design Philosophy ### Why Simulate Early The single most consequential decision in building performance is made in the first five percent of the design timeline. Orientation, massing, window-to-wall ratio, and floor plate depth are locked in during concept design, yet their impact on energy consumption, daylight quality, and occupant comfort persists for the entire operational life of the building — typically 50 to 100 years. Late-stage simulation is a diagnostic exercise. Early-stage simulation is a generative tool. The distinction matters because retrofitting performance into an already-resolved form is orders of magnitude more expensive than shaping the form around performance from the beginning. **Cost of late performance analysis:** | Stage where issue discovered | Relative cost to fix | |------------------------------|---------------------| | Concept design | 1x (baseline) | | Schematic design | 5x | | Design development
