HI
I requested both OTTV and solar gains for a building for two months.
The model shows values for solar gains higher than that of OTTV. (Units for both are total heat gain in Kwh for two months)
Since OTTV includes solar gains (or gains from windows via direct transmittance), in addition to gains via conduction, OTTV should be greater in all cases ( also as mentioned in OTTV (Overall Thermal Transfer Value) calculation method with Honeybee?)
Please suggest.
Is there a question here? What do you mean by “Please suggest”?
Hi Chris
I wanted to understand both the logic and listen to possible views (if any).
Hello,
We’ve created a Free OTTV Tool to calculate Overall Thermal Transfer Value automatically according to your local code.
1- Upload your IDF or GBXML file via this form: https://forms.gle/VGX51h5vgA8EFyZQ8
2- Download your OTTV Report according to your local code.
3- Improve your OTTV Output by modifying your Inputs via Table.
For more info, Feel free to email me
