These days, there is an increasing emphasis on making everything we do sustainable. Competition in the marketplace has taken us well beyond LEED, and in order to be “greener” than one's rivals, it helps to be able to embrace as many life cycle and environmental issues as one can. Architect William McDonough and chemist Michael Braungart's “cradle-to-cradle” philosophy, which advocates a “reduce, reuse, recycle” approach to the environment and our consumption of materials, is a starting point for how involved in this we, as both designers and citizens of the planet, have to be.
Light is a common cause of damage to paintings, drawings, books, artifacts, and virtually all types of historic and archival collections. It can cause paper to bleach, yellow, or darken, and it can weaken and embrittle the cellulose fibers that make up paper. It can also cause base materials and dyes used in documents, photographs, and art works to fade or change color.
