Blog: EMS - Why Isn’t Yours Working as Well as It Should?

Many buildings built for commercial and industrial use today still rely on energy management systems (EMS) from two to three decades ago as part of their industrial energy management tools. As expected, they are hardly up-to-date with the needs of today. 

They can limit the building management and automation potential and other risks such as cybersecurity vulnerabilities and frustrating building occupants. Thus, we return to the original question: why is your EMS not working as well as it should?

The answer to that may be simpler than imagined, and that is it has never fully worked at all. The reason is that the typical EMS in use today lacks the smart features necessary to achieve the expected results in present times. Compared to new smart facility management systems that collect hundreds upon hundreds of data points per minute, the EMS in production now only checks a fraction of it.

Moreover, these systems are typically commissioned initially to only reflect loads for every building, calculating based on variables such as time of day, climate, humidity, carbon dioxide levels, and more. The system works as intended when the data gathered from the environment matches the pre-sets for all variables. However, if only one variable differs, imbalances typically occur, leading to inefficiencies and, at worst, discomfort in the buildings.

Furthermore, your EMS most likely does not feature real-time mobile monitoring, limiting in this age where up-to-date information is essential for everything. If it has no such feature, it is safe to assume that it does not come equipped with remote control capabilities.

Managing things such as lighting, temperature, and equipment schedules are all basic features of a smart building management system (BMS), enabling facility managers to gain real-time insight over those settings and control them anywhere at any time as long as they have internet access via Wi-Fi or cellular service.


What Makes the Smart BMS Work Better?

Another factor wherein smart BMS does significantly better is by managing HVAC systems. Without it, HVAC systems tend to either be mishandled by technicians or not function properly. This, in turn, can lead to energy inefficiency, poor indoor air quality, and unhappy occupants, to name a few.

The lack of proper maintenance of HVAC systems leads to inefficient and over usage of energy, resulting in a significant increase in the power bill for the building. Smart BMS, on the other hand, keeps track of heating and cooling patterns.

Through adaptive algorithms, it calculates the required amount of energy needed for the next day and shifts to a lower energy setting. As a result, energy consumption drops by as much as 50%. Additionally, smart BMS also monitors the performance of HVAC systems. If a piece of equipment fails, it will automatically report the fault to the maintenance team.


Outside Air Optimisation (OAO) and Dynamic Airflow Balancing Make a World of Difference

With smart BMS, HVAC systems can be programmed to better suit the needs of your building. The systems can be shut off at certain times of the day or week when nobody is in the building and turned back on when there are people inside. The temperature and humidity can be adjusted for certain segments of the population. This can lead to happier occupants who are more comfortable in their workspaces, and it can also lead to energy savings.

Combined with modern techs such as cloud computing, machine learning technology, and the Internet of Things, optimising your system for energy efficiency and comfort becomes easier than ever.

For the dynamic needs of your buildings and their occupants, it only makes sense that a similar dynamic BMS fits the bill. It automatically adjusts to current and forecasted weather conditions, and solar levels daily are now made possible.

Among the three technologies mentioned previously, machine learning and cloud computing are the two that enable the smart BMS to come up with a thermal map of the buildings, making it simple to understand its unique characteristics, geographical location, energy loads, and even energy patterns. The system optimises outside air intake and balances airflow to provide a high-quality air supply at the right temperature only when and where required. The system’s efficient use of return air increases free cooling days that ultimately generate heating and cooling savings. With the smart BMS continuously commissioning the HVAC system, businesses can expect around 30% to 50% savings in energy costs.


How Good Are Your Lighting Controls and Scheduling?

Thanks to their smart capabilities, lighting solutions located in the interior and exteriors of a building, including parking lots and outdoor signages, can be fully automated and controlled by building managers no matter where they are as long as they have Internet accessibility. The photocell integration tying lighting zones to outdoor and indoor light levels can save even more time and energy. Furthermore, the smart BMS offers additional savings through dimming and scheduling options that are remotely accessible and backed by real-time visibility capabilities across the portfolio of buildings.


Conclusion

Although EMS functions as intended, for the most part, it is liable to suffer from issues that could lead to more problems and even worsen the system’s inefficiency. But with a smart BMS that is more fit for the current times, such issues are easily resolved while bringing more benefits to the table, notably remote and wireless access and real-time information updates. As such, it is worthwhile to invest in upgrading your buildings with the help of experts that deal with building and facility management in Singapore.
