High-Performance Buildings & Automation

Older BAS are typically replaced when BAS controllers and/or operator interface (the “brains”) are at the end of their useful life.

It will surprise no one that the smartphone app sector has taken a few shots at this problem.

When I first started in the HVAC industry working in a design consulting engineering firm, I came to accept that the HVAC sequence of operation and its associated contract specification, Automatic Temperature Controls (ATC), were provided by an ATC sales engineer.

Integration of a variety of non-BAS controls and systems has become an increasingly important aspect of building projects.

In many situations, sole-sourcing a BAS offers some definite advantages as long as you can skirt around any requirement to bid the work out.

In May’s column, I detailed the benefits to the owner of defining and enforcing a standard VAV terminal unit control sequence.

Is it time for a total system replacement or a phased approach?

There are various situations where integrating BAS products from multiple manufacturers can be useful.

Last month, this column addressed the fact that VAV terminal units are substantially more “variable” than even their name implies.
