DDC and BAS concepts
As an HVAC teacher I am constantly seeking new ways to explore and teach this subject, DDC and BAS. With the diversity of this particular topic, the number of manufacturers, it is very hard to know how to approach this subject from the point of view of someone brand new to this topic. I have been studying this stuff for years, and am now using Automated Logic hardware and software to teach this topic (only because that manufacturer donated this equipment and software with the hope of one day paying off and hiring some of my students), anyway, I have forgotten how I began to study this subject, and it's hard to prepare powerpoint presentations from the point of view of a beginner. But I keep trying. If anyone has a website, or even a good intro textbook please let me know...thanks.

If it's a book you're looking for I was given this book "Building Environments: HVAC Systems" when I started in DDC. It has plenty of mechanical stuff but there is a lot of stuff on generic controls as it was written by Johnson Controls. It'll suit any DDC system though.
Another good FREE download is the Honeywell's Engineering Manual of Automatic Control
Al did a very good job on his book and it has a lot to offer.

I use to teach controls and we always started with pneumatic controls. The students learned some basic formulas and how each component worked within a system. Then the students would learn DDC systems and have a basic understanding of control concepts.
