In building automation system applications, the most common types of analog signals are milliamp and DC voltage.
DC voltage signals are most often measured using 0-10V signals, but we also sometimes see 0-5V or 2-10V. The reason for the popularity of the voltage signal is it is easy to troubleshoot and almost all controllers will accept this type of signal.

If your facility currently has a legacy control system that needs upgrading but you don’t have the capital budget for a full retrofit, you are likely considering some form of building automation system integration. By integration, we are referring to an approach that would leverage some portion of your existing system while likely changing out some of the higher-level components such as the front-end software and/or parent-level controllers. Integration is a logical choice in this situation but before moving forward with this approach, there are some important elements that you should fully understand.

Smart buildings are becoming more common in modern-day society. Being that they are made up of a multitude of internet-connected devices, cybersecurity is of the utmost importance. These devices, if not safeguarded, can pose a highly desirable target for cybercriminals.

“Trim and response” is a way of controlling static air pressure (SAP) within a building’s HVAC system. SAP is one of the most important factors in HVAC design. SAP refers to the resistance to airflow in a heating and cooling system’s components and ductwork within a building. The push of the air must be greater than the resistance to the flow or no air will circulate through the ducts.
Continue reading Trim and Response for Supply PressureWhen it comes to building automation systems (BAS), Property Managers tend to lean on their facilities operations team to tell them what is going on and what needs to be done. A BAS can be daunting to understand, but at the same time, it is responsible for a large portion of tenant satisfaction and operational budget. While a property manager or administrator does not need to know the ins and outs of operating a BAS, having a basic understanding of how these systems work and what to look out for when evaluating potential service partners can make all the difference.
Covid-19 is an abbreviation of Coronavirus Disease 2019, which is the new coronavirus currently affecting the majority of the world. Its main transmission process is via the droplets of moisture contained in the air exhaled by people when they breathe or talk. The more rigorous the level of activity is, the more concentrated these exhalations become.
