Ladybug Results Problem

Hi Everyone,

I’m studying solar radiance on facade building with Ladybug and I get some results that I think that’s something wrong.

I´m simulating one floor at 10:00am, 15:30 pm and an interval 10:00 to15:30pm to São Paulo, Brazil. The results to 10:00am and 15:30pm are very high, and when I simulate the period (10 to 15:30) are lower. (The image is attached)

I’d like to understand why this soo different results and why results so high. I configure something wrong?

2. The results images has the some solar incidence color results for the four dates (21/03, 21/06, 23/09 e 21.12), but the sun are on different positions, the imagens could be different visual results too. I really don’t know if I’m doing something wrong.

Example 10:00am dates:

21/03, 21/06, 23/09, 21/12

Someone could help me ?

Thanks

Camila

I haven't checked your file but if you're running the simulation for a single hour the legend will be Wh/m2 and when it's for an analysis period it is kWh/m2. That should probably answer the difference between the results.

I attached two images, first one, simulation at 10 to 15:30 and the other one at 15:30h, and both the legend is Kwh/m².

And the results images the colors are the same for four days (21/03, 21/06, 23/09, 21/12).

Hi Camila,

The problem is that the simulation of 10-10 was not taking the period properly. I think it got confused as a period from 10 to 10 is not exactly a period but an instant.

If you change it to an HOY it works
