In Revit 2022, the heating and cooling loads analysis has changed. It is now called System Analysis. The icon for the system analysis may be found on the Energy Optimization Panel on the Analyze Tab.
The systems analysis and the Energy model work hand in hand.
If you use Revit for Heating and Cooling loads analysis, please note that you need to learn the new method before you start a project in Revit 2022. While the methods of modeling Architectural and Structural models will not change, the procedure for generating the analysis will, so Mechanical Engineers will need to adjust.
An easy way to do this is to consult the Revit help. Revit help is one of the most comprehensive resources and many people discount it in favor of YouTube. I have found detailed information that is even beyond the most advanced textbooks available.
Find the instruction and explanation of the new method of doing a heating and cooling loads analysis (systems or whole building analysis) here:
A little know fact learned from experience is that, if you are working with central models where a combination of Architectural and Structural models defines the boundaries of the spaces in an MEP model, it is prudent to close all the worksets of the MEP model when opening it. This ensures that the spaces generate correctly when you load the other links by switching on the worksets on which they are placed.
