Weather Files for iPIM

WeatherShift

Provides the option to submit any current simulation weather file and apply WeatherShiftTM process to generate files that represent the given location in a future time period using predicted climate change scenarios.

CIBSE 2006 Weather Files (For UK Building Regulations)

CIBSE TRY & DSY datasets are required to run simulations using ApacheSim method in VE Compliance. These datasets are owned by CIBSE and each user requires a license to use them. IES acts as an agent for CIBSE and the licence to use the data may be purchased on our website.

CIBSE 2016 Weather Files

Purchase CIBSE 2016 updated simulation weather files for 14 UK Locations. Test Reference year (TRY) and Design Summer Year (DSY) available based on current weather data and future predicted climate change data (UK Climate Impacts Programme).

METEONORM

METEONORM can produce energy plus weather files for almost any location in the world. Users can either purchase a license or ask them to generate datasets for certain location at a cost of around €80 per file.

Prometheus Weather Files

The PROMETHEUS project has produced a number of future weather files (.epw format) which can be used to 'future-proof' buildings against predicted climate change. The files were created using the UKCP09 weather generator. The weather files are currently available for 45 locations, 3 time periods and 2 emissions scenarios.

Australia Weather Files

A selection of EPW weather files for 78 locations in Australia can be found on the Energy Plus website. Place the .epw files in your Standard Data and Weather Files installation weather folder to read them in Apache simulations and VistaPro.

Agrément South Africa

Authorised weather files for use in energy compliance simulations in line with the National Building Regulations of South Africa and Agrément South Africa’s Energy Software Protocols (SANS 10400-XA Item 4.3).

ATHENIUM Analytics

Options to purchase weather data for individual locations as either AMY or TMY via Athenium Analytics (formerly Weather Analytics). Data is available for any global location using a 30km x 30km grid and is provided as both .csv (data) and .epw (simulation weather file).

Energy Plus Weather Files (EPW)

A selection of EPW weather files for more than 2,100 locations can be found on the Energy Plus website. Place the .epw files in your Standard Data and Weather Files installation weather folder to read them in Apache simulations and VistaPro.

Climate.OneBuilding.org

Provides TMYx climate data for more than 16,100 locations in more than 250 countries and another 3,200 files from other data sources. Place the .epw files in your Standard Data and Weather Files installation weather folder to read them in Apache simulations and VistaPro.
