Building Automation 101 – The Basics
Last week we focused on the concept of using the most powerful network available, the Internet, as the single data communication medium “connecting” all of the now disparate systems in our buildings into a single, integrated network. By doing so, we gain the ability to control, monitor, and gather data from all of these systems from anywhere, using only a web browser. Ultimately, having the ability to automate building operations will result in optimal efficiency and reduced operating costs, all the while giving tenants more control over their comfort.
By plugging these systems into our network backbone we can now achieve that goal of having the ability to control, monitor, and gather data from all these systems using Internet Protocol (IP) in a single, integrated network environment. The prerequisite, of course, is that we have a broadband and wireless infrastructure that will support the management of these systems and their requisite applications.
Building Automation Components
Let us briefly examine the most common building functions that might be tied together in an automated building:
Ideally, lights turn on at the correct lighting level when they are needed and are dimmed or turned off when not in use. Lighting systems today can be accessed and computer-controlled by the building operator or, in some cases, by the tenant via web-based control systems. Lights can be dimmed and turned on or off depending on whether or not the room is occupied. Lighting systems can now be linked to a centralized information system that can show current usage and usage patterns for either a single building or an entire portfolio via a Graphical User Interface (GUI).
Heating, ventilation, and air conditioning systems are often the core processes in a Building Automation system. Once automated, these systems can control the temperature, humidity and airflow, allowing tenants to adjust the environment in their individual spaces, thus conserving energy and controlling costs. Furnaces, chillers, and compressors can even be equipped with sensors that continually monitor the equipment for any indication of the need for preventative maintenance.
Fire & Life Safety
In addition to detection monitoring, many building functions need to be controlled in the event of a fire, earthquake, terrorist threat, or other emergency. Emergency exit locks need to be released, pre-recorded status messages need to be broadcast to relevant parts of the building, HVAC systems enabled for smoke extraction, etc.
Ingress to parking areas can be controlled via access cards or other electronic identification methods. In addition to access control, parking systems can integrate with security, lighting, elevator, and HVAC systems. These systems can be programmed to turn on and off for the individual tenant when they enter the parking structure. Visitors parking costs can be monitored and accounted for electronically, thus reducing administrative overhead.
Elevators and Escalators
Escalators do not need to run at full speed during off peak hours and all the elevators need not be operational when traffic is light. Access control cards can allow tenants programmable, selective access to certain floors. Interactive elevator terminals can stream content from CNN feeds to emergency instructions in the event of a fire or life safety situation.
Visitor management, access control, intrusion alert, and surveillance are the main functions of the security system. We can tie these functions together to allow a single operator control and monitoring of entryways, parking structures, elevators, hallways, and offices. Using IP-based video cameras, security personnel can now monitor multiple cameras via a web-based wireless device such as a Tablet PC without being tethered to a desk peering at an array of fixed monitors.
As we all know, the cost of oil, gas, and electricity fluctuate both seasonally as well as with market conditions. Building Automation systems can adjust the usage of the differing environmental control systems (electrical, gas, solar, oil), taking into consideration the cost of energy for each while also providing optimal tenant comfort.
By using computer controlled plasma or LCD screens, we can tie our digital signage to our Building Automation system, to our enterprise information and have real-time control of our signage content. When our leases become digital, tenant directories will be immediately updated once the tenant puts their digital signature on the lease and clicks the “OK” button. Building visitors are able to videoconference with tenants from the lobby and digital concierge services are now available to tenants for ordering business services, supplies, work orders, and pizza.
All of these systems need to be integrated into a single network in order to allow them to share information with each other. The problem is that these systems often use different data standards and protocols to communicate with each other, making integration difficult. The good news is that more attention is being paid to using Internet Protocol (IP) as the communication standard. We are not entirely there yet, but many more sensor and controls companies are developing IP-based products that will allow us to achieve seamless integration into an integrated Building Automation backbone.

UPCOMING REALCOMM WEBINARS
Commercial and Corporate Real Estate Cyber Risk - Developing a Comprehensive Strategy - 10/25/2018
Hardly a day goes by that we don’t hear about a Cyber breach. The most recent of scale was Equifax, the credit reporting agency in which credit information of 143 million of its clients was breached. While most of the incidents we hear about involve data or financial theft, there is a looming threat…our built infrastructure. This infrastructure includes everything from power plants to dams, but also includes the millions of buildings we use every day to work, shop, learn, recreate, manage our health and more. The threats range from unwanted building access to pirating of video surveillance and everything in between. This webinar will focus on the entire spectrum of Commercial and Corporate Real Estate cyber challenges, solutions and strategies.
