Optimization daylight and energy consumption

Honeybee Radiation Analysis help

Hello @OmidmRashidi I read your discussions which were helpful to me. I just got a couple of questions! In my case, I would calculate daylight that was perforated by blinds inside a room during a year using Honeybee_Run Daylight Simulation with analysis recipe component is HB_Annual Daylight Simulation, and HB_Read Annual Result I. So, I haven’t got a result that mentions how much daylight in each hour during a day, month and year! The blinds or solar screen have variables of thickness to manip…

Hello All,

I’m trying to optimize daylight and energy use as illustrated in the link above. Is it possible to tell Galapagos that increasing the daylight and decreasing artificial lights during daylight time? If so, how to do that? I saw a video tutorial by Mostapha https://www.youtube.com/watch?v=6c32kZN19FU&t=225s. He minimized and maximized the radiation, is it good to follow his expression with mine?
In Galapagos result, I got a thousand of population with variety of total of useful daylight illuminance (from HB_Read Annual Daylight I component) and electricity lights (from HB_Read EP Result component). How to analyze the result? The goal is to see the best thickness of blinds in all daylight time during months in a year?

I really need answers to my question!

Thanks in advance,
Raed

If I understand correctly what you really need to optimize is only daylight availability. The longer the space being day-lit the the less lighting energy you will use.

Thanks @mostapha for your reply,

That’s good!
I did 2 simulations. One is before running Galapagos (All blinds were opened), and another is after Galapagos. See the pics.

As you see the useful daylight illuminance 100_2000 is 595, and the majority of spots are 0! On the other hand, the result of useful daylight illuminance 100_2000 after optimization is 0!!! See pic.

Does that mean my script is wrong??

Also see the last pic. that is the file exported from Grasshopper to see the result from Galapagos.

The side of front blinds is oriented toward East.

Any idea would help!!

I would see better perforation of blinds with maximum daylight and minimum light energy use.
In Galapagos, there is 2 options; Maximize and Minimize in for the fitness. In my case I explained it what should I do?

Any suggestion or ideas?

Thanks,
Raed

use wallacei or octopus to optimize more than two parameters
