Sustainable architecture, often referred to as 'green building', is an approach to design that seeks to minimize the negative environmental impact of buildings. This is achieved through the efficient use of energy, water, and other resources, as well as by protecting occupant health and improving employee productivity. Key principles of green design include optimizing site potential, utilizing renewable energy sources like solar power, and specifying sustainable building materials. The implementation of these principles not only reduces a building's contribution to climate change but can also result in lower long-term operational costs. Consequently, governments and private organizations are increasingly adopting green building standards to mitigate environmental degradation and promote a healthier society.
