Are your sequences state based? Is there a finite set of conditions that drives your control sequences? If not, you may be missing out on one of the most intuitive ways to write control sequences. 

An increasing emphasis on variable speed pumping as a means to save energy in commercial buildings has provided engineers with many paths to efficient hydronic system design.

Last month, I started to explore when to use simple sequences and when to use complex sequences. Part of creating the correct sequence lies in the proper use of technology. 

It’s the heating season here in North America and that means building operators and controls contractors will soon be scrambling to ensure their heating systems are working properly.

In our day-to-day work as design engineers, this term is typically used in design discussions with an owner to imply some level of building data collection and analysis. 

The control systems we use in commercial buildings today have evolved over the last 30 years to provide systems that are cost effective, and provide good performance.
