ES. 2_LAB. 6_SOLAR RADIATION_Alimo Tatti

PROCESS:

To check the solar radiation that afflicts your home you have to:

1. First of all take the file from your former excercise

2. Add particulars to your home/building such as balconies, cornices, or openings that may vary the incidence of the sun on it: you can do this by clicking on "Create Mass", "Set" and specify the work plane on which you want to draw, then draw your shape and extrude as u need.

3. Once you have detailed your house you can click on "Analyze" and then on "Solar Radiation", click on the arrow on the top left of the window to select what you want to analyze, when you've selected all reclick it. Then choose in which season you want to have your check: click on the three dots at the right of Sun Study, select Multy Day and then choose the season, i suggest you to change the dates and put the ones you think fit better for a proper analysis, for example i changed the summer study from the 2nd of June to the 3rd of September. Then click on "Sunrise to Sunset". Choose the Accuracy of your analysis (i saw that it changes a lot if you get more accuracy so i put 85). Change the units in the one you know better as we always do (kW/m2 in my case) and watch your model all colored and analysed! your job is done!

ANALYSIS:

  here we see the radiations of the NorthWestern side of my house

 and here the SouthEastern one

we can see how during the summer the roof is a lot exposed to the sun radiations, in fact the second floor is really hot, unfortunally for me and my sister that sleep there.. but the jut of the roof is a really good thing for the facades, that are not afflicted by the sun, expecially the SouthWestern the should be the hotter. In fact during the summer i have to say that the living room and the dining room are really fresh and comfortable and they permit me to have some rest from the hot outside.

 winter radiations on the NorthWestern side

  winter radiations on the SouthEastern side

During the winter instead we can see that the roof is not that irradiated by the sun as during the summer, and instead the SouthEastern facade, where the kitchen and the dining room are, is a lot exposed, permitting the sun to warm the inside. Conversely the NorthWestern side is not that exposed, in fact that side of the house is really cold (obviously my bedroom is on that side.. i should have know this program before to choose better..).

In the end i have to say that i'm happy of my house, eventhough my bedroom is not the best one, as i prefer cold to hot, and my house is in general a fresh house.

Unfortunally for this exercise but fortunally for me my home, as i said in the former exercise, is in a new district, so it is relatively new, and it doesn't present forms of degradation. Maybe one day they'll come out and i'll remember this exercise... or maybe not...
