As a standard rule, please post the eQUEST file you are using to get these results, so we can see what other inputs may be affecting the outputs.

The reason for using an energy model is to capture the interactive effect of all building components when one item is changed, so the intuitive answer may not be the actual answer in any one specific scenario.

Subject: [Equest-users] Expert advice on Wall Insulation study in eQuest

Dear All,
We are working on a national level research project in India. A building envelope analysis is a part of this project. By doing analysis, we have found a vague results in trend (linearly downward) of reduction in energy consumption with reducing wall U-value in eQUEST.

Theoretically, the energy consumption should approach to stagnant with reduction in wall U-value.
Please refer figure.

Appreciate if anyone put light on this.

Thank you.
Regards,
Mayank Bhatnagar
Theoretical should come like this.
