Meteonorm !!exclusive!! Review

Meteonorm acts as a "stochastic weather generator." It doesn't just store old data; it uses complex algorithms to create synthetic hourly or minute-by-minute weather files based on long-term averages.

Meteonorm’s default datasets are historically anchored (e.g., 1991–2010). In an era of anthropogenic climate change, the assumption of a stationary climate is increasingly flawed. A building designed today using a historical TMY or synthetic dataset may face a significantly different climate by 2040. meteonorm
