This whitepaper by Siemens AG, published September 2023, addresses the urgent need to reduce energy consumption and improve efficiency within the built environment. Buildings currently account for 40% of global energy consumption and CO2 emissions, with a significant portion of this impact stemming from building operations. The whitepaper underscores the necessity for a digital and sustainable transformation of buildings to address the intertwined challenges of the energy crisis and climate emergency. By adopting smart technologies and leveraging data, buildings can significantly reduce their environmental impact, improve efficiency, and preserve their value for the future.
