The built environment refers to the human-made physical environment in which people live, work, and interact. It includes buildings, infrastructure, public spaces, and transportation systems. The built environment is designed and constructed by architects, engineers, urban planners, and other professionals to meet the needs of society.

The built environment plays a significant role in the quality of life of individuals and communities. It affects the health, safety, and well-being of people and has an impact on the environment. The design of the built environment can influence factors such as access to public transportation, availability of healthy food options, and the quality of air and water.

Sustainability is an essential consideration in the built environment. The use of sustainable materials, renewable energy, and green infrastructure can reduce the environmental impact of the built environment and promote more sustainable living. Sustainable design principles also emphasize social equity, economic viability, and ecological resilience to create healthier and more livable communities. WPI experts on the built environment include researchers in civil, environmental, and architectural engineering, fire protection engineering, and The Global School. Their work includes efforts to meet the infrastructure needs of the future, by using new materials that can reduce energy use and emissions, improve thermal comfort, limit maintenance costs, and address indoor air quality concerns.
