Calculating the optimal thickness for insulation is really tricky!
Thread Content
The formula for calculating the optimal thickness for insulation is quite clear; what’s problematic is that many parameters are unavailable, such as the cost of energy, the unit cost of the insulating material, and the annual depreciation rate for insulation-related investments； What is the difference between this and the value calculated based on the maximum allowable heat loss? How did you calculate it? Could you share these parameters?
It’s a professional issue; it would be great if it could be shared!
I hope some seniors can share their experience so I can learn from it
Look up these specifications; they all contain the relevant parameters. However, the calculated thickness is a bit large; basically, the minimum standard should be applied
