Principles of Sustainable Design

A link to a Wikipedia page which discusses:

Sustainable design (also referred to as "green design", "eco-design", or "design for environment") is the art of designing physical objects, the built environment and services to comply with the principles of economic, social, and ecological sustainability. It ranges from the microcosm of designing small objects for everyday use, through to the macrocosm of designing buildings, cities, and the earth's physical surface. It is a growing trend within the fields of architecture, landscape architecture, urban design, urban planning, engineering, graphic design, industrial design, interior design and fashion design.

The needed aim of sustainable design is to produce places, products and services in a way that reduces use of non-renewable resources, minimizes environmental impact, and relates people with the natural environment. Sustainable design is often viewed as a necessary tool for achieving sustainability. It is related to the more heavy-industry-focused fields of industrial ecology and green chemistry, sharing tools such as life cycle assessment to judge the environmental impact or "greenness" of various design choices.
