Great Videos!

Thank you Elif for creating these videos! You do a wonderful, thorough job explaining each topic. The videos with the helpful graphics do help me understand concepts better as I was struggling with that just by reading text books. Would be interested in seeing some content on HVAC systems.


  1. Christina, thank you so much for your kind review. Made me so happy…
    Yes, I will eventually cover all technical content, and mechanical systems are next in line. I still have one or two more lectures on Sustainabilty and & Environment related topics, though. But next is HVAC.
