WUFI

Hi, I would like to do hygrothermal analysis of sloped roof, which has photovoltaic panels on the roof. I have two question: 1- Without considering the PV on roof, the results of codensation risk and total water content of construction will be significantlz changed? 2-If yes , how can I consider thi...

Hi Dear I try to model a wall construction in wufi 2d that already I have done it by wudi pro. I need to have exactly input data and settings in both of them , but when I select the ' Treat as indoor surface' there are some input and settings that are related to the outdoor surface such a 'Adhering ...

I have already modeled a component in wufi pro and noe i want to simulate it with wufi 2d.When I selected local weather data file both the indoor and out door , I get an error in attached picture. Please help me what is it and what i should do?The out door file format is .epw and indoor is .wac. Tha...

Hi, I modeled an old wall construction that I already measured the temperature and Relative humidity of each layer.I don't have enough information about brick properties of modeled wall i have just thermal conductivity (0.4w/mk) and thickness?(25cm). I guess the brick is hollow brick or hollow concr...

It worked .Thanks very very much for your help.

No i did not switch to "Map/File" , it remained on perilously position and it is possible to choose other option.

Hi Dear, I have already created the indoor climate file in format of *.wac in wufi. I would like to use this file directly in wufi but when i put the tick of use left climate and i import indoor climate file , i should select again one of the standards of indoor climate. Finally output result of sim...

Hi, I Modeled a wall construction with 4 monitoring position that I have already measured temperature and relative humidity of this position via sensors. I would like to import my initial conditions file for each position. As you can see in attached picture the initial water contents which calculate...

I have recorded hourly indoor Temperature and Humidity of my case study in one year period now I want to import my measurement indoor conditions (Relative Humidity and Temperature) during the whole period of my simulation.I have two questions: 1- Is there a special format for indoor climate or it is...

Dear Thomas

Thank you so much for your quickly and completely answer.It was very useful for me.

I simulated a wall with 5 layers and thermal resistance of indoor and outdoor surface have been considered.Also I calculated the R value and U value manually.It can be seen in attachment Picture that the result of this 2 value in simulation and manually calculation are not same while the number , th...

I simulated the external wall and I would like to compare it with measurements data.The Thickness of layer and thermal conductivity of them are same but the total U-Value of the Measurement and simulated wall are not same. How can be considered the indoor and outdoor surface thermal resistance?It sh...

I try to simulate a construction of Aerogel (FIXIT 222), But I can not find some hygrothermal properties . I would like to get some input data of water Content: 1- free saturated water content (wf) RH=100% 2- Reference water Content(w80) RH=80% Is it possible to calculate them manually or just get ...
