“Energy demand is one of the most pressing concerns today and will remain a critical challenge in the future. While exploring new energy sources is one solution, optimizing the energy consumption of existing systems is equally important. According to leading agencies—including the U.S. Department of Energy (DOE) and National Renewable Energy Laboratory (NREL), Natural Resources Canada (NRCan), and the European Commission—buildings account for approximately 40% of total energy consumption, 75% of electricity use, and 35% of carbon emissions in developed regions. With most existing buildings being energy-inefficient, improving building energy performance remains one of the most impactful strategies for reducing energy demand and emissions.”
