Building Automation Systems (BAS) are essential to maintaining a comfortable and energy-efficient indoor environment in commercial and residential buildings. However, due to technological advances and changing regulations, many BAS systems need to be updated. This article will highlight the ten most common ways to know whether you might need a BAS upgrade and what to do to fix a minor problem. So, let’s get started!
Here’s a few telltale indicators it’s time for a BAS upgrade:
One of the most significant signs of an outdated BAS system is a lack of integration. An outdated BAS system may have to be integrated with the latest HVAC equipment. If it does not get upgraded, you will see decreased system efficiency. For instance, an outdated BAS may not be able to communicate with the latest programmable thermostats, which means the system cannot adjust temperature settings based on occupancy or weather conditions. This is easy to see during a sudden rise or drop in exterior temperatures, but the BAS system doesn’t adjust accordingly.
A modern BAS system should control and monitor HVAC equipment functions such as temperature, humidity, and airflow rates with speed and precision. If your BAS cannot perform these functions, you may not be able to maintain a comfortable indoor environment.
Today’s systems mostly feature smart technology. New equipment and procedures are based on that assumption. An out-of-date BAS may not support automated HVAC control; instead, it will require manual adjustments or operator intervention to maintain desired indoor environments. This can lead to increased maintenance costs and costly errors.
Poor indoor air quality due to insufficient ventilation and adequate filtration can cause health problems. It may have to be addressed even after a filter change. An outdated BAS system may have to be upgraded to integrate with advanced air filtration systems in order to achieve healthy indoor air quality.
An outdated BAS system may not support the implementation of energy-saving strategies such as demand response or variable air volume control. Some states have enacted new laws that older systems cannot meet.
A modern BAS system should be capable of collecting and analyzing data on HVAC equipment performance, energy consumption, and system efficiency. If your BAS cannot provide such data, you could be unable to identify areas for improvement or make informed decisions about system upgrades.
You may want your outdated BAS to become more scalable. Otherwise, it may set constraints on expansions of building floor space or additions of equipment. An upgrade would be necessary to accommodate the increased demand.
Cybersecurity is a critical facet of BAS systems. An outdated BAS should include adequate cybersecurity features, or it might expose the building to cyberattacks and compromise building systems. Plus, it might not be compliant with current cybersecurity standards and regulations.
A modern BAS system should provide a user-friendly interface that supports easy access to building systems data and real-time indicators of system performance. If your BAS has an outdated interface, users could be unable to navigate the system quickly, leading to inefficiencies and increased maintenance costs.
If your energy bills are unusually high, your HVAC system might be consuming more energy than necessary due to an outdated BAS. This can result in elevated operating costs. You can measure your energy use during peak hours and compare it to peak demand rates,thereby determining your system’s efficiency. Unfortunately, if it turns out to be the issue, a replacement is the only reasonable option.
In today’s economy, it’s looking more important than ever to cut costs and save money. When you own a commercial building, energy usage can be an important part of doing just that—and it’s easier than you might think!
Once you’ve grasped the most common reasons a BAS system may be outdated, diagnosing problems and fixing them become easier. A new system is expensive, so checking and trying to fix the following issues first can save money.
- Check the system for error messages, warning lights, or strange behavior. Look for any diagnostic tools the manufacturer or previous technicians provided to get further information.
- Verify the power and connectivity. Ensure the system receives power and the connections between the system’s components, sensors, controls, and the monitoring software or display panel are working correctly.
- Test the thermostat. Due to wiring issues or mechanical malfunctions, a faulty thermostat can cause problems with air conditioning or heating. Make sure the system thermostat works correctly and is set to the correct temperature.
- Clean or replace air filters. Check that the system’s air filters are clear and not clogged with dirt or dust, as this can affect the room’s air quality and overwork the system.
- Examine the sensors and other components. Inspect components like ductwork, sensors, fans, and cooling or heating coils to rule out any potential malfunctions with them. You will likely need a professional for a deep look into this.
- Analyze the software or control panel settings. Check the software or control panel settings, such as setpoints, schedules, alarm settings, and control algorithms to confirm they are configured correctly. We recommend you perform a system reset or restart in case of software errors.
- Contact a professional. If the issue persists after you’ve taken the above steps, it’s best to call an experienced HVAC technician who has the knowledge and tools to diagnose and repair faults with the BAS HVAC system. The technician can also provide routine service and maintenance to the system and related components.
There comes a point when it’s outdated, however, and must be replaced. If you go through the checklist and still do not succeed, at least you’ll know there are no other options. Though it can be expensive, it’s likely to save you money and keep your operations safer in the long run.
