Hello everyone !
I’ve been getting into honeybee for a few weeks now and i’m amazed by what it can do! right now i’m simulating a small building located in a tropical area for my thesis, and since humidity is an important factor in a tropical zone , i’m wondering how can i account for the humidity buffering capacity of, say a clay brick wall or a cellular concrete wall in an EP energy simulation ?.
Thanks in advance !
Interesting question. I believe you’ll need to find a way to translate the effect of a porous media into the U-value of a wall. From that point onwards, honeybee workflows will help you analyze energy and comfort metrics.
hi Devang and thanks for the feedback !
i believe that tweaking the U value will indeed simulate accurately the thermal behavior of a porous material, but won’t simulate (as far as i know , i may be wrong) the passive humidity comfort that the dehumIdifiying an rehumidifying capacity of such a material provides , and thus won’t reflect humidity comfort on the psych chart , for now just for the sake of visualising the effects on hygrometry on the psych chart i’ve worked arithmetically on the results to buffer humidy by a third ( for acurate numbers i’d recommend reading Dr. Tim Padfield articles ) to simulate a clay wall by using this function: Rh=(x-y)/3+y
x is the relative humidity output from the EP simulation and y is the average humidity .
