Why Wireless Devices Result in Lower Cost of Installation

Jul 17, 2017, 10:45:16 AM

Constructing your building management system with wireless devices can provide up to 80% labor savings and a 3-4x faster install, based on completed 75F projects. How is this possible?

Wireless devices use Internet of Things (IoT) technology to pair sensors, monitoring devices and control modules. Much of your existing HVAC, lighting and refrigeration equipment can still be monitored and controlled with a wireless building management system (BMS), so there are not many new wires that need to be routed or holes to be drilled in walls. This type of solution reduces new wiring costs, messes created during install and labor hours necessary.

Can You Trust Wireless, IoT Devices?

Good question. Can you trust the wired energy management system or BMS you currently have installed? Wireless sensors are inexpensive and relatively simple despite their extensive capabilities. Most of the real computing work is accomplished in the cloud. Wireless BMS devices are encrypted behind a strong firewall and operate on a mesh network, in which each node can relay data to any other node on the network. If a node fails or breaks, the nodes reconfigure to form new communication paths, using a self-healing algorithm.

If your Wi-Fi network goes down, the system will generate and send you an alert in 15 minutes and rely on data from the previous 24 hours as fallback data, which has been stored in cloud computing servers. Your system continues to operate reactively, which is still better than a programmable thermostat. As a failsafe, if the communication is down for a prolonged time period, your system can still function based on the last received schedule until connectivity is restored.

Maintenance with Wireless Devices

If a part of the system fails, you can pinpoint the issue immediately. Thanks to wireless monitoring, alerts can appear on your central control unit tablet, phone and via email to notify your facility manager of a malfunctioning node or piece of building equipment.

Most issues can be resolved over the phone. The ability to remotely configure and patch the system saves the expense of calling a technician and causing a truck roll every time your BMS has an issue. Remote diagnosis and isolation of issues reduces the amount of time a technician must spend on site for service calls, resolving issues that cannot be resolved remotely.

Flexibility of the Wireless Building Management System

Let's say your building is being remodeled, or maybe you decide that you want to change the zone dynamics on a particular floor. The wireless BMS and modularity of IoT devices allow you to reconfigure spaces and redefine zones with device pairing and connection methods so simple that school children can do it! Child labor aside, you can imagine the cost savings and freedom offered by such a flexible solution to building controls.
