CIBSE Weather Data

HI Shane,

Ive had to manually create a weather data folder and within that create a cibse folder. This is where i have saved both my Norwich DSY AND TRY files. I am trying to add these files to the weather data on Hevacomp, however it keeps on saying "weather file not found....". I have tried following step 1 on the 'installing cibse weather data' of downloading the ndx files, however the links do not work. 

Alternatively, i have used the browse button on the weather data to get the correct files up. I have used the TRY files for the ' select new energy weather data file' and the DSY file for the 'summer design year'. I have now run the CIBSE TM52 report and got results. Would you be able to clarify if firstly I have uploaded the correct TRY and DSY file to its correct location in Hevacomp weather data and secondly, if the alternative steps I have taken to complete the cibse TM52 report is correct.

Thankyou Shane.

Hi Aakil,

Thanks for the images - that confirms the reason for this. Your screenshot shows the Program Files (x86) folder.

The weather data is not at that location - it is located in the Program Data as listed here, ie:

C:\ProgramData\Bentley\Hevacomp V8i\Hevacomp\Weather Data\CIBSE\

If you cannot see you Program Data folder this will be because of your Windows settings - please see here.

Thanks Shane I've found the folder and copy and pasted the CIBSE DSY and TRY files in the correct location shown below. 

However, when i try to select the Norwich weather data file, its still coming up with the error message shown above. I have not purchased the future weather data files, only the current ones. I have tried following step 1 of 3 on the 'Installing CIBSE weather data' article, however the links to download the .ndx files are not working. Please can you help?

Hi Aakil,

Great, that looks like the correct location now.

The NDX files are for the future data only, so you can disregard that step.

You will just need to place the data files directly in the CIBSE folder, eg as below:

Hi Shane,

I have placed the data files directly in the CIBSE folder like shown below. I have closed down Hevacomp and started it back up, but I am still receiving the error message when I click 'add new energy year'. under Norwich cibse weather year. 

I realised that there are 3 types of Norwich DSY files, so i deleted type 2 and 3 from the Hevacomp>weather file>cibse folder and tried opening it up again with just type 1 Norwich DSY file in the folder. Unfortunately, the error message still came up. 

Please can you help?

Many thanks. 

Hi Aakil,

Sure, could you perhaps share the files you are attempting to use so I can check they are the correct format? Please find upload link here.

Hi Shane,

Would you be able to send the link again as it has expired. 

Many Thanks.

Hi Aakil,

Sure, please find new link here.

Shane

Hi Shane,

I've uploaded the CIBSE weather files.

Thanks.
