Premnath,
I enjoyed viewing the sequence of diagrams on your blog and I've bookmarked it for future reference, (for when I get on my next project!).
Yes, I believe being able to show such diagrams on design iterations very helpful... But we as architects also need to know the underlying concepts of what we can do to collaborate with MEP engineers and to plan and specify to achieve energy savings - so we we get it right from the get go and not have too many iterations.
Thanks for sharing.
