Weather Data Viewer 6.0 Features. The interface shows input cells in green. Stations can be selected by Region/County, WMO Station Number, or Latitude/Longitude. The Station Summary information updates automatically as the station is selected. After the parameters have been selected (right side), the blue link for Retrieve data.

Using a building envelope as an example, it is shown how to create a construction, how to set boundary, surface transfer and initial conditions and finally how to calculate and assess this example.

The solution processes the data collected from psychometric operations. It automatically generates charts displaying power consumption. The suite features customizable presentation parameters and offers editing tools for the input content adjusting the charts in real time. CARRIER Psychrometrics 5.1 can be downloaded from our software library. B uilding energy simulations require weather data as an essential input. ASHRAE, in collaboration with White Box Technologies (WBT), now provides web access to ASHRAE's IWEC2 'typical year' weather files for 3,012 international locations outside of the US and Canada.IWEC2 weather files can be purchased individually, as sets by country or region or as an entire set for all countries.

Guideline for the calculation of extensive green roofs

The “Guideline for the calculation of extensive green roofs” and the requisite material data sets have been developed to allow reliable WUFI® simulations and planning of green coverings, in particular on wood constructions.
These investigations were performed as part of the project

This *.KMZ file displays the locations of the weather files registered in WUFI’s database by feeding them to Google Earth (which you must have installed).
Some of these weather files are included with WUFI; the others must be purchased from the respective vendor, but they can then immediately be used for WUFI® calculations, without further configuration.

A click on one of the WUFI® icons will display some information about the respective weather file.

The 1991 weather data measured in Holzkirchen can be considered representative for Holzkirchen climate conditions. They are included in the WUFI® installation packages, but IBP also offers them separately for general purposes.

What is CCWorldWeatherGen?

The climate change world weather file generator (CCWorldWeatherGen) allows you to generate climate change weather files for world-wide locations ready for use in building performance simulation programs. It uses Intergovernmental Panel on Climate Change (IPCC) Third Assessment Report model summary data of the HadCM3 A2 experiment ensemble which is available from the IPCC Data Distribution Centre (IPCC DDC) (1,2). The tool is Microsoft® Excel based and transforms ‘present-day’ EPW weather files into climate change EPW or TMY2 weather files which are compatible with the majority of building performance simulation programs.

The underlying weather file generation routines of this tool are based on the so-called ‘morphing’ methodology for climate change transformation of weather data, which was developed by Belcher, Hacker and Powell (3). It builds on previous work by the Sustainable Energy Research Group on climate change transformation of UK weather data (4) (see also the web pages on the CCWeatherGen tool).

The CCWorldWeatherGen tool allows you to generate climate change weather files with a few mouse clicks. You can produce ‘morphed’ EPW and TMY2 files as well as present-day TMY2 files from the original EPW format files. The tool is made available free of charge. However, it is solely distributed WITHOUT the required baseline weather files and/or climate change scenario data! (Please view sections 2.1 and 2.2 of the CCWorldWeatherGen Manual for information on where to obtain the required baseline data.)

Important – please note:
The CCWorldWeatherGen tool uses coarse General Circulation Model (GCM) data. Therefore, CCWorldWeatherGen users are requested to familiarise themselves with the IPCC assessment reports to appreciate limitations and handle uncertainties of the climate change weather data generated with this tool. For sites in the UK it is recommended to use the CCWeatherGen tool instead, as this uses more detailed Regional Climate Model (RCM) data.

Please note that the tool does not currently work with the 2013 version of Microsoft® Excel. We are working on resolving this issue. In the meanwhile please use the 2003, 2007 or 2010 version of Microsoft® Excel for weather data conversion
