I’m trying to use CoolVent.
I’ve installed last version on my laptop, but, unfortunately my internet access is through a proxy server.
So, when I launch CoolVent, the program tries to check the last version and I get an error message.
+ Downloading did not succeed.
+ The remote server returned an error: (407) Proxy Authentication Required.
Is it possible to define a proxy for CoolVent or bypass the last evrsion check?
Congratulations on the great development of this tool! Nice to see how much has been done on the natural ventilation topic in the last 15 years. I noticed you had linked to Brian Dean’s research site. I also performed natural ventilation research work at the same time which is still up at cmiserver.mit.edu/natvent. I’d love to find a way to collaborate by providing access to buildings we’ve been involved in with a mixed-mode or natural ventilation scheme.
Please provide a website address for your results and we will post it.
Hello, I am trying to install coolvent in my computer, but is a Mac and the file does’t run. Do you have a Mac version?
Thank you very much
Unfortunately, CoolVent only works on Windows
I’m getting this error when trying to visualize the results:
Could not find file ‘C:\User\me\AppData\Local\Apps\……..\TemperatureOutput.txt’
Hi. if both java and .net framework have been properly installed, this problem is generally related to the decimal indicator. In the US we use a point, instead of a comma to separate decimals from integers. To solve this problem, it is necessary to change the computer configuration from a comma to a period as decimal separator.
The decimal symbol were the problem. 🙂
Hi I had the same error when trying to visualize the results. I checked my computer default. It is using period for decimals. Is there something else I should check?
This problem is generally related to not having Java (more likely) or the .net framework installed. You can download Java from here: http://www.oracle.com/technetwork/java/javase/downloads/jre8-downloads-2133155.html
Sometimes, uninstalling and installing it again helps. Also, I recommend that you reboot your computer after installing it, even if it does not tell you to do so.
When I run the setup, it says “cannot continue. The application is improperly formatted.”
This problem could be solved by updating t0 .net framework 4.5. If after updating you still have this problem, please have a look at this: https://support.microsoft.com/en-us/kb/974620
If this does not solve the problem, let us know.
May I ask if the weather files downloaded from Energyplus can be used in CoolVent since I would like to work on another city in Europe? Thank you.
Yes, you can. You can use .epw files by selecting “Other” in the city combobox and then click on the Browse button to select the weather file you want to use
Great! May I ask if we could export the weather files which already implemented in CoolVent so I have an idea how it looks like? Besides, do you have some standard case studies (detailed information about the parameters settings, like a tutorial)so that I can practice? Right now I used the data provided by Maria-Alejandra Menchaca-B. at chapter 9 of her phd thesis (2012, MIT) to model a steady case, but I got really weird results. Thank you.
May I ask if the temperature stratification model has been implemented in the present version? Thanks.
The model by Menchaca Brandan (https://dspace.mit.edu/handle/1721.1/74907) has been incorporated. Due to the assumptions of the model, it is only available when modeling buildings with no thermal mass. To see the stratification profile, double click on the zone of interest in the zone list in the results window
It is possible to know the wind pressure coefficient that CoolVent uses for urban low rise context?
CoolVent uses the method by Swami and Chandra in: “Correlations for pressure distribution on buildings and calculation of natural ventilation airflow”. ASHRAE Transactions 94(1), p. 243-266
