To gain a full and true understanding of the value of campus heritage requires shifting perspective. On many campuses, heritage resources are perceived to have no relevance whatsoever to the challenges of sustainability. This results largely from a profound misconception about what may constitute a sustainable future and what steps may be needed to achieve one. Campus heritage, far from being irrelevant, offers the most complete course in achieving sustainability in the time frame one has. Heritage buildings and the communities they form are models for how long-term benefit can be derived from the investment of material and energy resources. They have proven to be adaptable over time and welcome intervention by succeeding generations. Heritage buildings were built without addiction to fossil fuels. The precincts, neighborhoods, and communities they form are not dependent on automobiles. The places they make satisfy human aspirations and express culture that generation after generation finds valuable. Campus heritage has relevance more today than ever before. It is important to recognize its full and true value and apply its lessons to achieve a sustainable future. (Contains 3 figures.)
