Buildings contribute to 40% of the world's energy consumption and 30% of greenhouse gas emissions. Zero-energy buildings are used to reduce energy consumption, fossil fuel consumption and environmental impacts. In this analytical study, data was extracted from reliable databases and sources. 28,090 patents were filed between 1995 and 2024 in the field of nanotechnology applications in zero-energy buildings, with the United States, Europe, China and India leading the way in this field. The study aims to determine the effectiveness of nanotechnology in zero-energy buildings and environmental impacts. Nanomaterials in smart windows are used to regulate light levels, self-cleaning, hydrophobicity and energy consumption. Smart windows reduce cooling energy consumption by 36.9% and lighting energy consumption by 54.5%. Nanomaterials and phase-change materials contribute to thermal comfort by storing and releasing heat in building components during the day. Nanomaterials in building materials lead to a 40% increase in strength, a 35% increase in useful life, and a 20% decrease in energy consumption in the construction process, and these materials harm human health by entering the food chain and becoming toxic. Green synthesis, environmentally friendly nanoparticles, and recycling of nanomaterials play a role in reducing environmental impacts. Green nanoparticle synthesis effectively reduces energy consumption by 30%, production costs by 40%, and production efficiency by 50%. Municipalities, the government, industry, and universities contribute to sustainable urban development and confronting the energy and climate crisis in Iran through financial incentives, the development of laws and standards, and the establishment of nanotechnology observatories in construction projects.
