There are two primary categories of weather files used to analyze building energy demand and resilience:
Reliable weather data is available through several major repositories:
Many countries provide localized data, such as the Building Performance site for Aotearoa New Zealand. An In-Depth Look at Weather Files - ClimateData.ca The Weather Files
These are the most common files, created by statistically selecting the 12 most "typical" months from a multi-year period (often 10–30 years).
Relative humidity and barometric pressure. 3. Future Weather Files & Climate Change There are two primary categories of weather files
As the climate shifts, historical data (TMY) may become less representative of a building's future lifespan. Engineers now use to "future-proof" designs.
Tools like the WeatherShiftâ„¢ tool use climate model projections to adjust historical files for future decades (e.g., 2050 or 2080). Tools like the WeatherShiftâ„¢ tool use climate model
