I can hear Kjell saying "All models are wrong, but some are useful." Having said that we are having trouble getting usuable predictive energy use information from our electrical design engineer. They are telling us that their energy models are not for accurate pEUIs but just to compare various scenarios. Are they being lazy? Should we push for... Read more

This is something I have been tracking since last year. The same or similar bill was introduced in 2022 but failed by one vote.

Hi SCL,

I realize that there are already a couple of threads on this topic, but I didn't see anything from the past year.  We have been trying (unsuccessfully) to work with large rental companies to request jobsite trailers that are at a minimum energy efficient, and ideally solar/battery ready and/or built to passive house or similar...

Hey Gurus:

I have a client who is interested in reporting to their superiors on the status on energy codes in different states across the US. They are hoping to find some kind of summary that might show relative costs for HVAC systems under the various energy codes in effect across states. They are also interested in data that is...
