Green Buildings

What is a Green Building?

Green building is a whole-systems approach for designing and constructing buildings that conserve energy, water, and material resources. Green buildings are healthier, safer, and more comfortable.

In practical terms, green building includes:
  • Using sun and wind to the building's advantage for natural heating, cooling, and daylighting
  • Landscaping with native plants and using water efficiently
  • Building quality, durable structures
  • Insulating well and ventilating appropriately
  • Incorporating salvaged, recycled, and sustainably-harvested materials
  • Maintaining healthy indoor air quality with appropriate building techniques and materials
  • Using energy efficient and water-saving appliances and fixtures
  • Reducing and recycling construction waste
