Unlocking Potential: Using IoT for Energy Efficiency in Smart Buildings

30 May. 23

The dawn of the Internet of Things (IoT) has brought about a paradigm shift in the field of energy management and conservation in buildings. By utilizing IoT, we are ushering in an era of smart buildings that not only prioritize comfort and safety but are also highly energy efficient.

According to the International Energy Agency (IEA), buildings and building construction sectors combined are responsible for 36% of global energy consumption and nearly 40% of total direct and indirect CO2 emissions. These statistics emphasize the necessity for energy-efficient solutions in our buildings.


The Role of IoT in Energy Efficiency


IoT has the potential to revolutionize energy efficiency in buildings by providing real-time, actionable data that can drive significant energy savings. This is achieved through IoT devices like smart thermostats, lighting controls, and energy meters that optimize the use of energy within the building.

A report by the American Council for an Energy-Efficient Economy (ACEEE) suggests that smart buildings could reduce energy usage by an average of 18% with the help of IoT. This indicates the potential of IoT in improving the energy efficiency of buildings.

IoT Implementation for Energy Efficiency


Smart Thermostats


Smart thermostats learn from a building’s daily operations and activities, adjusting temperatures based on real-time data. This ensures the optimal use of heating, ventilation, and air conditioning (HVAC) systems, resulting in significant energy savings.


Intelligent Lighting


IoT-enabled lighting systems can adjust based on natural light availability and room occupancy, dramatically reducing energy wastage. IoT devices can automatically switch off lights in unoccupied rooms and dim them according to the amount of daylight present, optimizing energy use.



Energy Monitoring



IoT devices can track and monitor a building’s energy consumption in real-time. This granular data allows building owners and operators to identify areas of excessive energy usage and take immediate corrective action.


Case Study: The Edge


A prime example of a smart building leveraging IoT for energy efficiency is The Edge in Amsterdam. This building utilizes a connected LED lighting system that doubles as a data-collection network, contributing to a 70% reduction in electricity usage.


Future of Energy Efficiency with IoT


As we head towards a future where sustainability and energy conservation will become paramount, IoT will undoubtedly play a crucial role. With advancements in AI and machine learning, IoT devices will become smarter and more efficient at conserving energy.

A report by MarketsandMarkets estimates that the smart building market will grow from USD 66.3 billion in 2020 to USD 108.9 billion by 2025, at a Compound Annual Growth Rate (CAGR) of 10.5% during the forecast period. A significant portion of this growth can be attributed to IoT.




Predictive Maintenance


Another significant application of IoT for energy efficiency is predictive maintenance. Sensors embedded in various systems like HVAC, lighting, and elevators can track their performance and predict potential malfunctions before they occur. This leads to efficient energy usage and reduces wastage resulting from system breakdowns.

For instance, a study by Schneider Electric indicates that predictive maintenance could reduce maintenance costs by 30%, extend machine life by 20%, and lower breakdowns by 70%.


Automated Systems


Automation is a key component of smart buildings. IoT devices can automate energy-consuming systems such as lighting, heating, and cooling based on occupancy and usage patterns. This eliminates unnecessary energy consumption, leading to a reduction in energy costs.

Green Buildings and Sustainability


IoT promotes the development of green buildings, which use resources like energy, water, and materials more efficiently than buildings that are merely built to code. IoT devices can monitor and manage these resources, thereby reducing the ecological footprint.

The integration of IoT in our buildings is a giant leap towards energy efficiency and sustainability. By unlocking the potential of IoT, we are paving the way for a future where smart buildings are the norm, resulting in significant energy savings and a smaller carbon footprint.
