Our built environment contributes a high percentage of carbon emissions and is one of the causes for global warming. Sustainable architecture and design (often called green construction and building) is the "practice of erecting buildings and using processes that are environmentally responsible and resource efficient. Green buildings limit their environmental impact by conserving as much energy and water as possible and are constructed of recycled or renewable materials in order to achieve maximum resource efficiency."
Typically, buildings are designed to meet building code requirements, whereas green building design challenges designers to go beyond the codes to improve overall building performance and minimize life-cycle environmental impact and cost. Many sustainable architecture and design professionals earn the Leadership in Energy and Environmental Design (LEES) Accredited Professional (AP) credential. With a degree in sustainable architecture or design, graduates can work for professional architecture, building, landscape and design firms. These positions typically require time in the office as well as in the field working with clients to design, construct and monitor/certify designs.
