Hi!
While not specifically a modeling remark, the attached paper from Rocky Mountain Institute shows how changing your design mindset can bring huge energy benefits.
For you experienced modeler / designers: if you designed a system to require less pump or fan energy (larger duct/pipe with fewer / wider bends), do you try to capture this in your model? How so?
Thanks!
