As I understand, adaptive thermal comfort is calculated as a function of prevailing outdoor temperature. Inputting this value returns a fairly large comfort range, based on the fact that occupants can take adaptive measures (clothing change, opening windows, etc.).
I am currently testing natural ventilation simulations, to explore how building design can affect comfort. Air speed in a building is an important factor - two naturally ventilated buildings in the same location but different air speeds will be perceived differently.
Is there a way to make this explicit? I.e., is there a formula that adds wind speed as a parameter to the adaptive thermal comfort model, or is there a different model for this altogether?
Dear Max,
There is my ATHB approach, which combines
A) PMV and adaptive model (Schweiker, M. and Wagner, A., 2015. A framework for an adaptive thermal heat balance model (ATHB). Building and Environment, 94(Part 1), pp.252–262.),
B) SET and adaptive model (Schweiker, M. and Wagner, A., 2017. Influences on the predictive performance of thermal sensation indices. Building Research & Information, [online] 45(7), pp.745–758. ) or
C) TNZ and adaptive model (Schweiker, M., Huebner, G.M., Kingma, B.R.M., Kramer, R. and Pallubinsky, H., 2018. Drivers of diversity in human thermal perception – A review for holistic comfort models. Temperature, [online] pp.1–35. Available at: .).
As such, you can model adaptive effects together with the influence of air velocity, clothing insulation level and other factors available in PMV, SET, or TNZ. Still all versions are based on limited data and would require further validation, so that you are of course free to use them, but should carefully check your results.
All of those models above are implemented in the R package comf (https://cran.r-project.org/web/packages/comf/index.html) - check the following in R
?calcATHB for help
calcATHBpmv for equations of PMV application
calcATHBset for equations of SET application
?calcTNZPDF or calcTNZPDF for help on TNZ application or its equations
Let me know in case you have further questions or problems to use the R package.
Marcel
Thanks Maohui Luo ! in case you or anyone else would like to add a function to the R package comf, just get in contact with me via mail or through https://github.com/marcelschweiker/comf , I am happy to add more to it.
Hi Marcel Schweiker , thanks for sharing! This looks very promising, I'll try to wrap my head around it this week and get back to you.
Marcel Schweiker, Thank you for sharing all this informations with us,
this my email: [email protected] in case I will have your help I will write you back.
Thank you again
and Thank to Maohui Luo
