· 28 · Vol 0ne ® The impact of buildings on carbon emissions 36% of the EU’s CO2 emissions are from buildings. These solutions capture indoor light to power IoT sensors and devices, reducing the need for wiring and batteries. This lowers costs and minimises environmental impact. The promise of light-powered devices Indoor solar cells, which capture indoor light to generate power, offer a sustainable and low-maintenance alternative to traditional power sources. This technology aligns with the broader shift towards decentralised energy systems, where energy generation is distributed across numerous small-scale sources rather than centralised in large power plants. Light-powered IoT devices are particularly beneficial for retrofitting existing buildings. Many older buildings lack the infrastructure to support extensive wiring for new technologies. By using light-powered devices, these buildings can be upgraded with minimal disruption and cost. This approach supports efforts to increase building renovations and improve energy performance. Environmental benefits and operational efficiency Light-powered solutions not only reduce energy consumption but also address environmental challenges associated with traditional energy solutions. Smart Spaces In the EU, buildings are responsible for approximately 40% of total energy consumption and 36% of CO2 emissions. This significant impact underscores the importance of improving energy efficiency in the built environment. Legislative measures are essential, setting ambitious targets for energy efficiency and greenhouse gas reduction. Smart technology: revolutionising energy management A major advancement in energy management is the integration of smart technology, particularly the Internet of Things (IoT). IoT devices significantly enhance the management and optimisation of energy use in buildings. By collecting and analyzing real-time data, these devices enable more efficient and responsive building management systems. This not only reduces energy consumption but also improves the comfort and functionality of buildings. Sustainable power solutions and cost efficiency A key factor in deploying IoT devices is the total cost of ownership. Traditional power solutions often require expensive wiring or frequent battery replacements, which can be costly and environmentally damaging. Sustainable power solutions offer an innovative alternative by enabling light-powered devices. Transforming the built environment with light-powered innovations The energy sector is moving towards sustainability, driven by the need to reduce carbon emissions and optimize energy use. Buildings, which are the largest energy consumers in Europe, play a crucial role in this transformation. The integration of smart technologies, legislative measures, and innovative energy solutions is shaping the future of energy management in buildings. One ground breaking innovation is the use of light to power IoT devices, such as sensors and thermostats. Light energy harvesting is set to revolutionise building operations and energy consumption.
