WUFI

Hi,

I got a message about parameters that I have defined previously but, the software detects as an error...so my concern is if the results will not be accurate...
in terms of ach, what is the range of ach for a pitched roof with strong, normal and low ventilation?

Hi Alberto,
the warning indicates that heat transfer coefficients have been defined for the pitched roof model, but the corresponding reduction factors have not been specified. These reduction factors can be selected from the "Reduction Factors" drop-down menu.

This warning does not necessarily mean that your simulation results are inaccurate, but you should review and complete these settings to ensure the model is configured as intended.

For more information, please refer to the "Pitched Roof" guideline, which explains the purpose and correct use of the reduction factors in detail.
