Nowadays, the new generation of smart devices allows Building Management Systems (BMS) to easily monitor and optimize building performance, while leveraging the power of the Internet of Things (IoT) to quickly identify potential issues.This article will reveal what the IoT is and how it works; it will also introduce eight use cases of smart buildings where IT-supported BMS devices have helped support a range of cost control and profitability-enhancing applications.
The widespread use of IoT devices has made it easier to promote enhanced smart building functionalities within existing devices. This allows us to easily control costs and gain many revenue-enhancing features. Here’s how:IoT devices come with built-in capabilities to connect to existing internet infrastructure and communicate. IoT devices do not require each individual system in the Building Management System (BMS) to be equipped with a dedicated network; instead, they use a standardized set of communication and security protocols for “plug and play” functionality.This makes it easier to collect information from various types of sensors or monitoring devices and to use this information to control and manage the operation of various building management devices.How does the IoT work?Strictly speaking, IoT devices refer to any devices that can connect to a building’s Wi-Fi or local area network using a standard IP (Internet Protocol) address. This allows IoT devices to share information with other devices or controllers anywhere on the network.Today, IoT devices include a wide variety of devices, from doorbell cameras to HVAC thermostats. They can even be as simple as a single light bulb or door lock. In each case, the individual addressing capability allows the device to provide information and receive instructions from any other connected device with that address.IoT and BMSIoT devices are driving a new wave of smart building automation that enables different types of devices to work together to share information, whether with a central unit managing one or multiple building systems or directly between local sensors and control units.This reduces the cost of installing or upgrading BMS systems, as each independent system controlled by the BMS no longer requires a separate data network for control. Standardized protocols can also sometimes make it easier to integrate older or “legacy” devices with newer control systems.This, in turn, can enable many intelligent features, such as doors or lights that tenants can control via their smartphones. However, IoT-driven intelligent features can also have a real impact on profits.
Eight Major Applications of IoT in Smart Buildings
Let’s take a closer look at eight specific ways IoT devices can help improve building profitability, whether by enhancing control and reducing management costs and other operational expenses, or by adding features or services that existing or future tenants are willing to pay for.
1. Optimize HVAC and Lighting SystemsBy connecting motion sensors that detect occupancy in real-time to HVAC thermostats and lighting systems, areas of commercial buildings can be activated as needed. This also allows tenants to feel more comfortable in the areas they are using while saving heating and lighting costs in unused areas. Connecting real-time occupancy sensors to access control systems or even tenant scheduling software can further optimize energy spending, while smart temperature sensors can compensate for seasonal or daily temperature fluctuations, leading to real savings. What are the results? Monthly and annual energy cost savings provide added value for owners and investors, as well as added value for tenants.2. Better Building SecurityIoT technology means that access control systems, security cameras, motion detectors, and door locks can be connected in one system without each system requiring a separate dedicated network. This makes it easier to control who has access to the property and allows security personnel to track and manage potential threats. This means better protection for property and tenants’ assets across all properties, reducing losses and associated costs such as on-site security and insurance premiums. IoT-supported systems can also be connected to the registration logs of enterprise tenants. For residential buildings, access can be enabled through an integrated smartphone application to manage building access and “additional features” such as delivery or bike storage. By investing in conveniences and value-added services that tenants will appreciate, the value of rental properties can be increased.3. Enhanced Environmental ControlSmarter, more interconnected building management systems allow us to control the environment of buildings, not just adjust heating and lighting systems. IoT-supported sensors, timers, and motors can be installed to alter the geometry of solar arrays for maximum solar tracking efficiency. Similar systems can adjust window shades throughout the day to maximize natural light while minimizing glare and direct sunlight. Fine-grained humidity control can also be added to maintain humidity levels when needed to increase comfort. By fully utilizing installed solar capacity and the building’s natural heating and lighting, direct savings on energy costs will be seen. The indirect benefits of transforming buildings into more comfortable places for tenants to live or work will also be evident.4. Improved Water ManagementBesides electricity, water bills can be one of the largest expenses for owners or tenants. Smart water management can help reduce costs and increase profitability. The cost of heating water is high, but maintaining a certain temperature is relatively inexpensive. IoT-supported thermostats on water heaters can be set to lower temperatures during off-peak or low-demand periods. Sensors monitoring flow rates from heaters, storage tanks, or even individual toilets can quickly detect pipe leaks and shut off water supply, limiting water damage and controlling costs from leaks when the building is unoccupied. Additionally, smart irrigation systems can water during nighttime or cooler periods, helping to control landscaping costs. As temperatures rise, more advanced systems can increase irrigation times.5. Enhanced Remote CapabilitiesAs more businesses shift to hybrid work schedules, both offices and homes need to be better set up to manage remote work. IoT-supported technology can help BMS adapt. While IoT systems allow for 24/7 access to facilities, they also enable enterprise tenants to provide remote “on-demand” access to buildings, as well as advance booking of parking spaces and meeting rooms, which can help reduce costs and protect profitability as many businesses reduce their footprint. Allowing residential customers to open doors for employees or delivery personnel, or remotely start heating or air conditioning, is also a valuable convenience for today’s busy lifestyles.6. Lower Replacement CostsIoT devices are often cheaper and easier to replace. This is because IoT components are more likely to be generic parts designed to provide specific functions for a wide range of applications. Therefore, the installation and operating costs of IoT-based BMS are lower. By providing a standardized way to connect and communicate with devices, IP protocols can replace many types of dedicated devices and reduce the need for a dedicated network to connect them.7. More Predictive MaintenanceIoT sensors collect information about the operational status of key equipment in the BMS. This data helps track the operating time of on-demand devices like heat pumps and compressors for scheduled maintenance. Alternatively, performance information can be used to predict and schedule maintenance to maximize equipment lifespan and minimize system downtime. In some cases, potential issues can even be detected early, allowing for intervention to prevent equipment damage and reduce disruption to tenants.8. Greater Sustainability and ComplianceThe accurate data collected by BMS from IoT sensors also provides valuable insights into the sustainability of buildings and their operations. Data from multiple sensors helps measure impacts, such as improving insulation in parts of buildings, providing actionable information on how similar upgrades affect energy savings in other buildings. Real-time data on how BMS helps reduce energy costs can minimize tenants’ carbon footprints. It can also help comply with local environmental regulations and assist in obtaining tax credits or rebates.
