Some factors that influence whether buildings are sustainable include the materials used in construction, the energy efficiency of the building's systems, the design and layout of the building to optimize natural light and ventilation, the use of renewable energy sources, and the building's overall impact on the environment. Additionally, the location of the building, its water usage and waste management practices, and the maintenance and lifespan of the building also play a role in determining its sustainability. Overall, a combination of these factors must be considered in order to create a truly sustainable building.
