Files — The Weather

The .epw (EnergyPlus Weather) format is a global standard developed by the U.S. Department of Energy . Other common versions include TMY3 and IWEC 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.

These files help predict how cooling demands might increase and heating demands decrease as global temperatures rise. 4. Sourcing & Global Repositories The Weather Files

Tools like the WeatherShift™ tool use climate model projections to adjust historical files for future decades (e.g., 2050 or 2080).

A widely cited repository for updated TMYx files and climate change data. As the climate shifts, historical data (TMY) may

Many countries provide localized data, such as the Building Performance site for Aotearoa New Zealand. An In-Depth Look at Weather Files - ClimateData.ca
