Sustainability doesn’t only pertain to environmental factors; in terms of affordable housing, sustainability is broken down into three parts: environmental, social and economic. Environmental sustainability addresses the minimized use of resources, minimal pollution and the protection of local biodiversity. Social sustainability covers a wider swath of factors, including adhering to ethical standards during building development, integrating the building with the surrounding community, providing housing to meet various needs, and providing social services and facilities. Economic sustainability is simple: Social housing developments should support local economic diversity and provide employment opportunities to residents.
