Sustainable design has become a necessity rather than a luxury in today’s world, as the building and operations sector consumes a significant share of global energy. The strategy for reducing the carbon footprint begins with the careful selection of raw materials, where designers consider the concept of embodied energy—the total energy consumed in extraction, manufacturing, and transportation. Choosing sustainably sourced wood or using locally available materials, such as stone, can significantly reduce transportation-related emissions. In addition, passive design strategies play a key role in minimizing reliance on mechanical systems. These include designing spaces to enhance cross ventilation and utilizing the thermal mass of walls to absorb heat during the day and release it at night. Moreover, daylighting is essential—not only for reducing electricity consumption but also for improving the physiological and psychological well-being of occupants. The shift toward a circular economy in design is another critical aspect, where elements are designed for disassembly and reuse rather than disposal. Technology also contributes significantly through smart sensors that monitor energy usage and automatically switch off systems when spaces are unoccupied. Ultimately, the goal is to achieve net-zero energy buildings, where a building generates as much energy as it consumes, positioning interior designers at the forefront of efforts to combat global climate change.
