• BAS Design Drawings : A CAD-Intensive Design is Expensive!
• BAS Specifications: Can Too Much Be a Bad Thing?
• BAS Physical Architecture  Why Is It Important To The Design?
• Back to BASics:  Sequences of Operation
• Back To BASics – Point Selection
• Back To BASics – DDC Controllers (Part 2)  Architecture & Interoperability
• Back To BASics – DDC Controllers (Part 1)
• Back To BASics   Sensors and Actuators
• Back to Basics - Control Loops
• Intelligent Building Integration  More intelligent building ideas can be found if you apply this type of Imagineering to each building’s unique operating requirements, especially those that differ from that of a typical commercial (i.e., office) building.
• Multi-Manufacturer BAS  for Large & Multi-Building Owners
• The Future of BAS: A Year Later  For this year-end, I’d like to look at my current vision for the future of BAS over the longer-term.
• Can BAS Terminology Be Standardized? The key here is never to assume that your terms are universal and that they mean the same thing to everyone else.
• New BAS Developments  – Exciting or Good Marketing?
  
• Retrofitting a BAS – The Devil’s In The Details
• Who Are The “System Integrators”?  The challenge to this discussion is that there is no clear agreement about what a System Integrator should be doing.
  
• Should You Sole-Source a BAS?   As with many BAS issues, the answer to this question is “it depends.”
• Upgrading Old BASs  Is a Gateway in Your Future?
• Additions to Existing BASs  There’s more to it than you might think!
• BAS Integration For Factory Mounted Controls  It’s time to revisit the design challenges that continue to plague a successful controls merger.
• Will ASHRAE’s 2016 90.1 Increase the Demand for DDC Controls?  The latest 2016 version of 90.1 has expanded its scope to include remodels/additions to existing buildings.
• The Future of BAS Manufacturers  I believe that analytics and artificial intelligence needs to trickle down into the firmware of DDC controllers to have the maximum impact.
• The Future of BAS  I want to thank Paul Ehrlich for his years of dedication to this column and am excited to be able to provide readers with my Building Automation thoughts, insights, etc. on a monthly basis.
• Co-authored with Paul Ehrlich many columns.
