The Untapped Potential: Empowering Energy Efficiency in Existing Buildings with IoT and AI


In today’s fast-paced world, the advancement of energy efficiency and sustainability is more important than ever. Commercial buildings contribute significantly to global energy consumption, accounting for 40% of total electricity consumption. As technology advances, data-driven insights have emerged as a powerful tool for optimizing energy consumption. However, many existing buildings, particularly older ones, have yet to adopt these solutions. This has resulted in numerous obstacles to meeting energy efficiency targets.


The Sharp Reality: The Buildings Are Old, So The Used Solutions Are

Let’s investigate the untapped potential of existing buildings as well as the market challenges that block their transition to a greener future.


Outdated Infrastructure

Outdated infrastructure in commercial buildings poses significant challenges to effective energy management, hindering the adoption of modern technologies and best practices. According to a study by the U.S. Energy Information Administration (EIA), approximately 60% of commercial buildings in the United States were constructed before 1980, indicating a large portion of the building stock is equipped with outdated systems and equipment. The impact of outdated infrastructure is evident in the energy consumption statistics. Buildings constructed before 2000 consume 23% more energy per square foot compared to buildings constructed after 2000.


Limited Real-Time Data Visibility

Limited real-time data visibility is a critical challenge in commercial building energy management, limiting the ability to make timely and data-driven decisions. Only 28% of facility managers have access to real-time data on energy consumption and building performance, according to a survey conducted by the International Facility Management Association (IFMA). This lack of real-time data visibility limits the ability to quickly identify energy inefficiencies and effectively respond to changing energy demands.


Fragmented Building Management

Fragmented building management results in inefficiencies and increased energy consumption. According to a report by the Building Owners and Managers Association (BOMA), nearly 60% of commercial buildings manage various aspects of building operations using multiple systems from different vendors. This lack of system integration and coordination results in disparities in data, making it difficult for facility managers to gain a comprehensive view of energy usage and performance throughout the building.


Time-Consuming Energy Audits

Time-consuming energy audits significantly impact the energy management of commercial buildings, often leading to delays in identifying and addressing energy inefficiencies. According to a study by the American Council for an Energy-Efficient Economy (ACEEE), traditional energy audits can take several weeks to complete, which can result in missed opportunities to implement timely energy-saving measures. Moreover, the complexity and manual nature of these audits make them resource-intensive and costly for building owners and operators.


Limited Awareness and Education

Building managers are frequently unaware of the potential cost savings and environmental benefits that energy-efficient measures can offer. Furthermore, a lack of knowledge about available technologies and best practices can result in poor energy management decisions. To address this issue, governments and regulatory bodies around the world are enacting building energy efficiency regulations. The European Union, for example, has set ambitious targets for improving building energy efficiency through initiatives such as the Energy Performance of Buildings Directive (EPBD) and the Nearly Zero-Energy Buildings (NZEB) standard. These regulations aim to raise awareness and encourage the use of energy-efficient building construction and operation practices.



Low Hanging Fruit For Energy Efficiency: IoT and AI

According to the National Renewable Energy Laboratory (NREL), nearly 30% of the energy used in commercial buildings is wasted due to inefficient operations and equipment. Significant energy waste results in significant financial losses for building owners and operators. Commercial buildings can identify energy inefficiencies and optimize their operations by implementing energy consumption monitoring via IoT deployments and AI-based solutions, potentially leading to energy savings of up to 40%, according to Deloitte.

AI algorithms can analyze this data to identify areas of energy wastage and recommend optimized control strategies. For instance, AI can adjust HVAC systems based on occupancy patterns, weather conditions, and indoor air quality to ensure energy is used only when necessary. Additionally, AI-powered predictive maintenance can detect and address equipment issues proactively, reducing downtime and energy losses.

IoT deployments enable the integration of smart sensors and meters, allowing building managers to monitor and manage energy usage remotely. This level of visibility empowers them to make data-driven decisions and implement energy-saving measures effectively. Moreover, IoT-enabled smart devices can be interconnected, creating a network of sensors that work together to optimize energy consumption across the building.
