More on VAV...

Hi again!

We received a lot of comments on VAV over the lass three weeks.

First, many of you agonized over how complex and involved it is to get a VAV system to operate, particularly in a large facility.

Second, those of you involved in promoting this technology commented on the safety and savings it offers.

Third, others involved in air filtration technologies suggested that current methods allow many fumes to be removed from materials in containment devices and the purified air re-introduced into the lab at great energy and financial savings.

Fourth, California is now trying to assemble and codify some specific issues into 2019 Title 24 CASE Proposal for Automatic Sash Closure Systems (12/13/2016). Among other things, this Title 24 revision would mandate auto-sashes be added to new VAV systems in very specific ways.

These issues, to make a long story short, will not wait. They are being debated and judged right now in at least one state.

While we on this site have been evaluating a variety of solutions and discussing our varied experiences, others are saying "enough already" and moving to codify certain solutions. Maybe this is good, maybe this is a bit premature.

What do you think? Many of you who are involved in these matters may feel my characterization of this whole situation is not accurate. Many may have first hand experiences that are relevant here. I would like to step back and see if I can generate some discussion on this whole situation. After hearing from you all, I will try to put something together to summarize all your viewpoints. Thanks in advance for your comments!
