How much time does your technician team spend working vs trying to work? You might have the best team of technicians and contract services support that can be found but are you making it more difficult than it should be for them to service your building systems? You might be and not even realize it.

Processes and tools that might have streamlined workflows when they were first introduced could be causing bottlenecks now. But to clear those you don’t have to scrap what you’ve been doing, you can improve operations by building on what works with a BMS app.

What is a BMS App?

A BMS mobile app is a cloud based building management system. It functions much like the traditional BMS terminal that your teams have used for years but instead of placing that data in a static, standalone location it places it in the pocket of team members through a mobile device. A BMS app connects using BACnet protocol to give users a direct, secure connection to key system data points.

BMS Software or BMS Mobile App

You can access BMS data through a desktop terminal or mobile device. While the same basic information can be accessed, the difference is in the details.

 

On-Site Terminal

BMS App

Availability

At a stationary terminal an HVAC technician might have to wait to get the system detail they need until an electrician is done using the BMS for their work.

With a BMS app, every technician can get the information they need, whenever they need it. And apps can be customized and information segmented so each technician only sees the system detail they need.

Access

With a BMS terminal a technician has to get a reading, run back to the equipment, run back to the system, make an adjustment and then repeat the process until everything is operating effectively.

By using an app a technician can get the system readings they need right at the work site.

Accessibility

When BMS data is only accessible in a singular location and format it can be complicated and cumbersome to find and view what you need..

With a cloud based building management system, performance updates and alerts go with you. And in a form and format that matches your usability needs.

Usability

Terminal displays can be “one-size-fits-all” in the way that information is displayed and accessed.

The best BMS app can be customized to the users’ preferences. This makes accessing information easier.

Response

When an issue arises it will only be discovered when someone sees the alert on the terminal.

When an issue arises, everyone with access will get an alert simultaneously.

Satisfaction

Tenants can quickly grow tired and frustrated at always having to bring issues with IAQ, heating, cooling, lighting etc to a building manager’s attention. They expect the management team to find and fix issues quickly.

With alerts delivered to key team members in real-time, issues can be addressed before a tenant is ever aware of them.

The Technician Runaround

Does this sound familiar: You hire an onsite HVAC technician to work on an air conditioning unit on a particularly humid day. The system is on the roof so that’s where they start. They make some adjustments but then have to wander through the building to the basement where the BMS terminal sits. They check some readings and then it’s back to the roof. More adjustments and another trip to the basement. It’s a cycle that continues until the machine is operating efficiently again. What’s not efficient will be the invoice you receive for a technician that spent half of their time walking, not working.

Cloud-native building management systems with mobile access and automation can be used to eliminate this work/check/work loop. Technicians can get information at the equipment, making adjustments and repairs and getting performance data nearly simultaneously. It makes the work more efficient and frees up a technician’s time to do more of it.

Information Access

Teams are more efficient when they are informed and a BMS app allows every member of your team to get the same information at the same time. This doesn’t just make routine maintenance easier, it also helps when systems need immediate support. If an alarm is triggered everyone finds out at the same time and can immediately address concerns with each individual system as needed.

You can also control the flow of information, so if you have a contractor in to support your team you can limit what types of information they can see and how long they can have access to it.

The Only BMS Mobile App You Need

A BMS app can free up the responsibilities involved in building system maintenance and service tasks. It can help technicians work more effectively by allowing every member of the team to have the same point of truth no matter where in the building they are working. In fact, the power of a cloud based BMS software is in its ability to be customized to match your building system data outputs with the needs, schedules, and responsibilities of your staff.

FAQs

How can a BMS app help technicians service building systems more efficiently?

One way that a BMS app can improve efficiency is by letting technicians access system readings directly at the equipment where they are working. This can eliminate repeated trips between the equipment and a stationary BMS terminal. 

Why would a building team replace a BMS terminal with a mobile app?

A mobile BMS app gives technicians access to the information they need without requiring them to use a shared, stationary terminal. It can also push performance updates and alerts directly to the technician. 

Can multiple technicians access building system information at the same time?

That depends. A BMS mobile app can be configured to deliver system data to multiple team members at the same time. With a standalone BMS terminal, technicians can only get the information they need when they are at the terminal. 

How does ODIN’s BMS app reduce technician runaround?

Technicians can get system readings at the equipment they are making adjustments and repairs to while those are happening. This reduces the need to travel between equipment and a BMS terminal to check system performance after every system tweak. 

What is the difference between an on-site BMS terminal and a BMS mobile app?

An on-site terminal requires technicians to access BMS information from a singular location, while a BMS app puts access to that information on a mobile device. The app also allows system information to be customized and segmented for individual technicians. 

What does BACnet connectivity provide in ODIN’s BMS app?

ODIN’s BMS app connects to building systems using BACnet protocol in order to provide users with a direct, secure connection to key system data points.  

How can a BMS app make technician workflows more efficient?

A BMS app can build on existing processes and tools rather than requiring a team to scrap what it has been doing and learn new processes.  

Is information customizable in a BMS mobile app?

Yes, apps can be customized and information can be segmented so each technician only sees the system details they need. This makes accessing information easier than using a one-size-fits-all terminal display. 

What happens when a building system triggers an alarm with a BMS app?

When an alarm is triggered from a building system, everyone on the team can find out at the same time. They can then immediately address concerns with the individual system as needed instead of not realising a system problem is in progress until a catastrophic event.
