With the rise in global population, we're seeing an increasing number of people gravitating towards city life. But as more people live closer to one another, this urban shift often leads to problems like increased traffic congestion and more complications when managing essential services.

A new trend in developing "smart buildings" offers promising solutions to these problems. These structures use automation technology for managing a range of tasks from intelligent lighting controls and temperature regulation to air quality management and improved security.

But the key to making these buildings truly "smart" lies in harnessing the power of IoT (Internet of Things) technology.

Smart Buildings: What Exactly Are They?

Smart buildings come equipped with a host of IoT devices. These devices use sensors to track different parameters and interpret the information while providing recommendations for improved operational efficiency.

The process involves using real-time data to optimize how a building operates in response to the changing environment and user needs.

The technology can also improve maintenance operations by providing predictive monitoring, and alerting staff to potential failures before they happen. This approach reduces costs associated with reactive maintenance while increasing safety for occupants.

Essential Elements of a Smart Building

Most smart buildings comprise fundamental pieces that help manage the whole structure.

Wireless Connectivity

In today's smart buildings, uninterrupted wireless communication is crucial. It enables the core functionality for devices within the building to connect, interact, and reach out to external networks.

Typically, tools like Wi-Fi, Bluetooth, and 5G are used to ensure a strong wireless connection. These forms of connectivity enable instant data sharing and facilitate remote control over numerous building functions.

Data Collection and Analysis

An integral aspect of smart buildings is their effectiveness when it comes to data discovery and interpretation. Sensors placed throughout the premises monitor various building parameters, from ambient conditions like temperature and humidity to energy use patterns and how populated the spaces are.

By using specific algorithms, the data collected is then processed to discover certain patterns and evaluate the efficacy of different building components. Relevant metrics, such as electricity use patterns, can shed light on potential energy wastage, while data on people's location in the building can help when fine-tuning temperature control schedules.

User Interfaces

The user interface is what serves as the meeting point between inhabitants and the building's smart features. Whether it's a fixed touchscreen panel, a mobile application, or voice-activated assistants, this interface is a crucial element of smart buildings.

For optimal performance in smart buildings, the interface chosen needs to be user-centric, easily navigable, and responsive.

Why are Smart Buildings Beneficial?

  1. Improved Sustainability: One standout benefit of smart buildings is their role in curbing energy consumption and decreasing carbon footprints. They intelligently tweak heating, cooling, and lighting based on real-time occupancy, ensuring no excess energy gets wasted, leading to a greener planet.
  2. Better Efficiency: Every facet of a smart building, from its HVAC system to its security measures, is geared for top-tier efficiency. The integration of automation and instant data processing means these structures not only save energy but also translate into cost reductions in the long run. A smart thermostat, for example, changes temperatures in sync with daily routines and room occupancy, helping to lessen energy use and lower utility costs.
  3. Detailed Reporting Capabilities: Smart buildings generate comprehensive data insights, covering aspects from power use to how spaces within are used. This data analysis equips building administrators with the information they need to make strategic decisions about upkeep, energy conservation tactics, and other key operation features.
  4. Personalized Experiences: Beyond efficiency, smart buildings excel at creating environments that suit the individual preferences of those inside. By picking up on patterns and likes of occupants, these structures modify elements (be it lighting colors, ambient temperature, or even background music) to create a setting that’s both comfortable and promotes efficiency.
  5. Improved Safety and Security: Safety gets a significant upgrade in smart buildings. With innovations like smart locks, CCTV feeds, and responsive emergency systems, security is a built-in feature and not an afterthought. For example, if there was a fire outbreak in a smart building, the system could instantly unlock exits, light up escape routes, and notify emergency services.
  6. Smarter Use of Space: Smart buildings also make more intelligent use of space. Sensors can monitor which areas of a building are being used at what times, enabling organizations to maximize their space usage and potentially reduce real estate costs.

What Industries Make Use of Smart Buildings?

Smart buildings have a wide range of applications and can benefit various industries. Some common sectors that already make use of smart buildings include:

Commercial Real Estate

Within the commercial property sector, the momentum towards smart buildings is unmistakable. These intelligent structures not only streamline facility management but also help to keep employees happier and more productive. Also, in an age where environmental consciousness is paramount, smart buildings stand out as a proactive step for companies aiming to minimize their carbon footprint.


Healthcare facilities such as hospitals and clinics are also using smart buildings. These technologies can support patient care by automating environmental controls, reducing energy costs, and improving security measures. IoT devices are also commonly used to monitor patient health and assist medical staff in their duties.


In the manufacturing sector, smart buildings can help improve production efficiency and safety. By monitoring equipment performance and environmental conditions in real-time. These buildings can predict maintenance needs and prevent potential issues before they occur.


Smart buildings can enhance the shopping experience in the retail industry while optimizing store operations. For example, smart lighting systems can automatically adjust to the time of day or occupancy levels, and real-time data analysis can provide insights into shopper behavior.


The hospitality industry is also beginning to benefit from the use of IoT. Specifically, hotels are able to combat the challenges they’ve historically faced when it comes reducing their carbon footprint and cutting operating expenses.

Lantronix was recently relied on by Hotel Marcel in New Haven, CT to help redesign a 50-year old building into a unique, net-zero energy hotel. Using PoE++ switching solutions in combination with advanced low-voltage solutions provided by Sinclair Digital, Hotel Marcel is now able to generate 100% of its own power and is now one of the few LEED Platinum-certified hotels in the country.

Creating a Smarter Future

There has been a noticeable increase in the amount of sectors that use IoT devices and smart buildings. As this technology continues to advance over time, smart buildings will no doubt redefine how we live, work, and protect the environment for years to come.
