I have a HB problem- Outdoor thermal comfort related.
I’ve been working on comparing MRT field measurements with the outputs from the HB UTCI component but am having trouble getting results close to my measurements. I THINK because I don’t have the correct material properties set for the model’s ground/floor so I’m wondering if anyone can help my finetune the material properties? - The ground is a kind of pebble dash roofing tile which i’ve currently set based off a mix of the properties from Solid rock & Dry Dust because Solid Rock was giving me close LW MRT and Dry Dust close SW MRT. But that isnt really working out
Images of experimental set up and HB model below. (Basically the roof tiles are the roof of the ground zone with an ‘orphan’ shade connected to the model as the textile)
Here are the current results with red as the simulated values and blue as the measured values. First pic is: MRT, longwave MRT and MRT shortwave delta
Second pic is: air temp under the shade, and ground surface temp
And here are the direct and diffuse rad values for the same period if anyone is wondering about that weird peak mid morning. Wouldn’t mind an explanation for that too?
Also the EPW values have been replaced with local weather data collected on the analysis day including air temp, rh, wind speed and direction and radiation values.
