Predictive Climate Data

NC-v4 EAp2:Minimum energy performance
posted by  Dave Hubka  on 

Hello, 

Wondering if anyone is using predictive (i.e., Future) climate data rather than past climate data when performing energy models. 

Thanks!

I'm certifying a huge factory with an attached office building. Is it possible to model only the office area?

Are there any firms performing energy models with future predictive climate data rather past published climate data?

Hi! I know that we have to describe the construction of the opaque envelope and reference the 90.1 Appendix A table in the minimum energy performance calculation.
