I was asked to do an Indoor Comfort Analysis. I am trying to use different SHGC values in order to decide the best strategy. I did both PMV and Adaptative simulations. When the material on the glass is OFF there is lower heat in the areas. But when I add the SHGC trhough eponstructions the heat is higher and it doesn´t matter the value I add. I trying that the calculate the difference of heat between glass with 0.55 SHGC and 0.80 SHGC.
The issue hee is that I don´t know if I am doing it correctly or not. Because as far as I know I am following the correct method but the result is the same.
Here find attached the Rhino model and both the PMV and Adaptative comfort on grasshopper.
The VT is a required input is required. For early-stage, low-resolution simulations I often just set it to the same as the SHGC, but ideally you would check the manufacturer’s datasheets:
The EPWindowShades component finds the windows in a model and applies shades parametrically to these windows. Therefore, your addHBGlazing should come before this:
You have set natural ventilation to occur every time the indoor and outdoor temperatures are between 0 and 50 degrees, but realistically no one opens windows at 0 degrees:
As you can see, the results are quite similar. This is because the space is air-conditioned; in the SHGC 0.8 variation, you are probably just using more energy to keep the room temperature acceptable. If you are interested in comfort, I suggest either using comfort maps, or, switching off the AC for the simulation to see how well your space performance in passive mode:
Wow!! Thank you so much, I am an amateur with this softwares, I´ve been struggling with this simulation for a week and always having the same result. I did try though the shades as a context, but still my mistakes where in other areas I did not knew how to solve. I started from the example of Hydra, and as you can see I didn´t need the SolveAdjacencies that where in the original model.
I´ve been monday to sunday learning this amazing software, and the forum is quite helpful, thabk you again Max!!!
Hi @MaxMarschall
do you know that EP Window Shades can also be used in the Honeybee Plus algorithms? Or the equivalent of this component is available in Honey Plus! I did not see .
