Reconstruction:
The act or process of depicting, by means of new construction, the form, features, and detailing of a non-surviving site, landscape, building, structure, or object for the purpose of replicating its appearance at a specific period of time and in its historic location.
The Reconstruction Standards establish a limited framework for recreating a vanished or non-surviving building with new materials, primarily for interpretive purposes.
Rehabilitation:
The act or process of making possible a compatible use for a property through repair, alterations, and additions while preserving those portions or features which convey its historical, cultural, or architectural values.
The Rehabilitation Standards acknowledge the need to alter or add to a historic building to meet continuing or new uses while retaining the building’s historic character.
Restoration:
The act or process of accurately depicting the form, features, and character of a property as it appeared at a particular period of time by means of the removal of features from other periods in its history and reconstruction of missing features from the restoration period.
The limited and sensitive upgrading of mechanical, electrical, and plumbing systems and other code-required work to make properties functional is appropriate within a restoration project.
The Restoration Standards allow for the depiction of a building at a particular time in its history by preserving materials, features, finishes, and spaces from its period of significance and removing those from other periods.
Scientific value:
The embodied illustrative and/or associative values of a site and its capacity to reveal more about an aspect of the past through examination or investigation of the place, including the use of archaeological techniques. In addition, scientific value may pertain to past scientific accomplishments, advances in scientific thought, or the potential of a site to advance scientific research.
Social and communal values:
Social value is associated with places that people perceive as a source of identity distinctiveness, social interaction and coherence.
Communal value derives from the meanings of a place for the people who relate to it, or for whom it figures in their collective experience or memory.
Therapeutic Landscape:
The concepts of therapeutic landscapes and medical topography acknowledge the intentional design and perception of the natural environment in relation to the prevention and cure of disease.
Use values:
The use and appropriate management of a place for its original purpose illustrates the relationship between design and function.
Vulnerability:
Any factor that may alter or impact the site’s significance now or have the potential to do so in the future.
