Manufacturers are touting some interesting new BAS technology developments on their websites. This is welcome news since BAS advances in the recent past have mainly been about web-server operator interfaces and interoperability.
Web servers have now become the de facto approach to operator interface, and the products continue to improve their ease of use across a variety of devices beyond PCs. Interoperability continues on a path of providing more functionality and becoming easier to implement across a greater variety of BAS and other types of systems. However, neither of these advances have made BAS easier to install and use overall or — more importantly — substantively better at improving building comfort and energy efficiency.
