Mean Radiant Temperature Estimations #144

Open benterich opened 1 week ago

Is your feature request related to a problem? Please describe. Not really a problem, just something I would find useful. There are various ways to estimate Mean Radiant Temperature, hence it would be useful to have it in this package.

Describe the solution you'd like One method that can estimate Mean Radiant Temperature. For example the "traditional method" by Fanger, "Six-directional method", "Black globe thermometer method".

Preferably I would propose, one MeanRadiantTemperature Class, that holds the various methods and its inputs.

Describe alternatives you've considered Otherwise, its also possible to create seperate methods for each estimation independantly.

I can inccoperate them :)!

I completely agree that it would be nice to have equations to estimate the mean radiant temperature.

There is already one function that allows you to do that, it is called solar_gain_on_people. The name for this function is not great and we could consider a better naming convention. Moreover, the function to calculate the MRT from the globe temperature is also there already.

I agree that we should have one class/funcition and then people can choose the method they use. Please note that, I am in the process of updating all the function in pythermalcomfort, you can see how I am structuring them by looking at the development branch. I have not updated all the function yet, but you can have a look at the adaptive ASHRAE function.

It would also be very useful to incorporate a function that estimates mean radiant temperature based on the solar radiant, cloud coverage. The authors of the Clima App, have already done that and they have described the method in this paper.

Could you please help me find all the functions we can use to calculate the mean radiant temperature and then we can have a quick call in which we discuss how we are going to add them to pythermalcomfort?

Yes, i would love to help out!

I saw how you updated the functions and it seems clear to me. I am gonna have a look at the estimation done in the ClimaApp and gonna collect all to me known methods to estimate MRT. Then I can make a quick concept which we can dicsuss, ideal would be after the 2nd December, since then i have conducted my masterthesis defense.

Kind regards, Ben

Great to hear that my new code makes sense. As you can see it is not finished but I am planning to work on it as soon as I get back to Australia.

Yes, after the 2nd of December works perfectly since I will be travelling until the 3rd of December. All the best with your oral defence.

I think it is going to be fantastic if we collate all the code to calculate the MRT and include all these functions in pythermalcomfort. Matzarakis Andreas also did some work on this topic and there are applications like RayMan to do the calculations. Perhaps there are also some review papers that they discuss this topic, if there is not perhaps we could consider writing one once you have collated all the functions. :)
