Custom Window Opening Profile

[Farhan34]

Hello,

I wanted to know weather it would be possible to make a custom window profile within daily profile without the need to use scripted ADO (UK TM59 Part O compliance) profile provided by IES. For someone who doesn’t work with Python scripts, I was hoping to get a simple editable version of this.

According to Part O, all of the following limits on CIBSE’s TM59, section 3.3, apply.
a. When a room is occupied during the day (8am to 11pm), openings should be modelled to do all of the following.
i. Start to open when the internal temperature exceeds 22°C.
ii. Be fully open when the internal temperature exceeds 26°C.
iii. Start to close when the internal temperature falls below 26°C.
iv. Be fully closed when the internal temperature falls below 22°C.

I wanted a editable version of this within the daily modulating profile. Which supposing if I want to have window being opened at night with a degree, I can just add a fraction and it would work while the profile still doing everything as mentioned above.

Now I made different formulas within daily profile but I don't know that they satisfy above criteria (Part O) or not. If someone can help would be greatly appreciated.

Formula (two options):
1. IF(ta <= 22, 0, IF(ta >= 26, 1, (ta - 22) / (26 - 22)))
2. ramp(ta,22,0,26,1)

Any other workaround to the scripted ADO profile would also be welcomed.

Thanks.

Hi Farhan,
you can use the scripted profile and make some changes in that to keep the window open during night with some restrictors.

Hope this helps, thanks.
