The Ultimate Guide to Smart Buildings IOT Technology


Smart buildings have been around for a long time, though not in the form in which they exist today.

Building automation goes back to the late 1800s, when a Wisconsin schoolteacher named Warren Johnson invented the thermostat. While early automation focused on controlling indoor environmental conditions, a budding environmental movement in the 1960s and an ensuing energy crisis in the early 1970s saw energy conservation begin to drive building design. The arrival of digital building controls, building information modeling, open protocols, and WiFi further transformed the way buildings function.

Today, networked IoT devices, cloud computing, and analytics driven by machine learning (ML) are revolutionizing smart buildings in ways never before possible. But capitalizing on this cutting-edge technology requires understanding your options.

What Are Smart Buildings?

A smart building automatically controls building operations based on real-time variables to achieve specific goals. As technology writer Phillip Tracy says:

A smart building uses sensors, actuators and microchips, in order to collect data and manage it according to a business’ functions and services. This infrastructure helps owners, operators and facility managers improve asset reliability and performance, which reduces energy use, optimizes how space is used and minimizes the environmental impact of buildings.

Technology is what gives built structures “intelligence”. However, that intelligence isn’t a characteristic of a single system component. Rather, it is the result of a technological ecosystem that includes IoT devices, ML-driven analytical software, and automated building management systems (BMSs).

The Benefits of Smart Buildings

Smart buildings have significant benefits over traditional built environments, including:



Analytics software continuously collects, organizes, and analyzes data to provide critical insights into building conditions and performance.


Environmental Impact

Efficiency-focused smart technology is a critical tool for minimizing the carbon emissions that contribute to climate change.



Intelligently automating systems that regulate lighting, heating, cooling, and air quality creates more comfortable spaces for building occupants.


Health & Safety

Smart technology monitors indoor air quality, controls building access, and maintains healthy lighting and thermal conditions to keep occupants safer.



Analytics software identifies potential issues with building systems before they become big problems and makes automatic adjustments to restore optimal performance.


Reduced Energy Costs

Smart building systems use energy only when and where it is needed, reducing costs.

Many new builds are designed to realize these benefits from the start. However, building owners who retrofit existing structures with smart building technologies will also see a meaningful return on their investment.

Smart Buildings Technology: The Essentials

Smart buildings are created using well-architected systems software and hardware. Each component within these systems should be thoughtfully chosen to ensure you achieve your goals.


IoT Devices

Smart buildings rely on IoT sensing devices with a wide range of capabilities. These devices can work within the existing wired infrastructure of retrofitted structures but typically use wireless access points.

The most common IoT devices include:

  • Temperature
  • Humidity
  • Motion
  • Occupancy
  • Contact
  • Indoor air quality
  • Gas
  • Smoke
  • Pressure
  • Proximity
  • Water quality
  • Electrical current monitoring

Many IoT devices work on open protocols. This allows them to communicate with other devices and systems, along with analytics platforms and other building software.



Wireless devices are essential for smart buildings but won’t completely replace the wired legacy systems found in many structures. Rather, wireless devices supplement the capabilities of a smart building’s cabling backbone. Yet due to how conduits in older buildings are constructed, retrofitting buildings often requires tearing down walls or adding ports. Because of the added expense, new approaches have been developed.

In newer smart buildings, IoT devices depend on built-in wireless access points while wired IT infrastructure follows pathways and consolidation points in common with a building’s electrical system. Power over Ethernet (PoE) technology combines these two roles, making Internet cabling capable of also carrying electricity.

Though this still uses fixed cabling routes, it offers considerably more freedom for designers and architects of smart buildings. Technology continues to advance, and newer innovations like Li-Fi, which may replace other wireless technologies, are being developed to make connectivity in built environments even more accessible and reliable.

Wi-Fi reliability is a key concern in smart buildings. IoT devices need connectivity in order to transmit data. There are strategies, however, to control smart buildings even when connectivity is temporarily lost, including:

  • Using a mesh network to allow devices to communicate with each other rather than sending data to the central control system.
  • Using smartphones or other mobile devices to create a mobile ad hoc network (MANET).

A smart buildings service provider with a controls background will understand both the control systems and the smart technology that overlays them.


The Cloud

Cloud computing is opening up new opportunities to safely harness the potential of building data. The cloud allows you to avoid the upfront cost of on-site data storage and offers great flexibility as your needs change.

Some buildings need some level of on-premises data storage for regulatory reasons. However, cloud servers are often more secure than their on-premises counterparts, as the best cloud providers use cutting-edge cybersecurity strategies and do not require virtual personal networks (VPNs). A cloud provider also has the ability to continuously back up critical data across a range of servers in multiple locations for redundancy.

Though there is still considerable discussion over which security strategies to use, best-in-breed measures allow users to integrate the most innovative software and devices from multiple developers and manufacturers.



Analytics software is what makes building data powerful. An advanced analytics platform continuously mines data to provide deep visibility into building performance and optimize building systems. This means more comfortable, healthy, and energy-efficient environments.

Key features of analytics applications:

  • A mobile-first dashboard gives you access to insights from any connected device.
  • Advanced automation opportunities based on custom rules minimize the need for manual intervention and the risk of human error.
  • Machine learning capabilities improve automation over time.
  • Advanced fault detection and diagnostics identify anomalies as early as possible, use multiple layers of analysis to identify root causes, and recommend solutions.
  • Prioritized alerts reduce nuisance alarms.
  • Predictive analytics identify technical issues before failures occur and empower you to create better strategies for the future.
  • Customizable reports with user-friendly graphics ensure all stakeholders have the information they need.

With analytics, you gain a new level of control and get direct access to the brains behind your smart building.



In order for IoT devices, analytics applications, and building systems to work together seamlessly, they need to be integrated. An integration platform-as-a-service (iPaaS) that uses open protocols is one of the most innovative ways to do this.

An integration platform ensures data flows into and out of a smart building’s systems unencumbered. Supported by cloud servers, such platforms negate the need for complex configurations, manage relationships between data sets, and normalize data. The result is a unified system with powerful capabilities and great scalability.
