This document discusses sustainability and quality lighting design. It defines sustainability as meeting present needs without compromising future generations' ability to meet their own needs. Sustainable design components include low energy use, renewable energy sources, recycled/recyclable materials, local materials, and responsible site selection. Quality lighting has three components - economics, human needs, and architecture. Some conflicts designers face include dark sky ordinances, color rendering, high lighting requirements, energy limitations, and balancing client and code requirements.
