Historical conservation is an important practice in the US that safeguards our cultural heritage, relating us to our past and instructing our present. However, with rapidly increasing awareness concerning the environment, the intersection between preservation and sustainability needs to be addressed.
Can sustainable historic preservation be a practical and regular alternative?
That is the core question of this blog post, explaining the very importance of historic conservation surveys in achieving a balance between protection and sustainability.
It is a systematic process of identifying and assessing historic resources. These include buildings, districts, and objects that are important for historical, architectural, archaeological, or cultural reasons. In simple words, it is the point of departure for preservation planning, which is a means of intelligently deciding about protecting and managing historic properties.
The Survey and Evaluation Unit coordinates the evaluation of historic structures in New York State. A statewide inventory of historic preservation planning at the local and regional levels complements NY's conservation program. This unit offers technical assistance and more information on the procedure.
Surveys play a crucial role in bridging the gap between preservation and sustainability in several ways:
Surveys thoroughly detail the existing physical condition of historic structures. This includes materials, construction techniques, and energy performance characteristics. All these details will be important in developing appropriate and sustainable interventions. Knowing how a building was originally constructed will enable informed decisions regarding green building retrofits and upgrades.
Surveys will help identify some of the intrinsic sustainable features present in historic buildings. For instance, natural ventilation strategies, passive solar design elements, and the use of locally sourced materials. Those can be preserved and enhanced during the rehabilitation process.
In addition, it will unveil the areas in which energy efficiency could be enhanced without compromising their historic integrity.
By understanding the building’s history, experts can retrieve a lot of information. It informs the sustainable rehabilitation strategies and choice of materials and techniques suitable for the building. For instance, using compatible materials in repairs would help preserve the long-term historic fabric of the building while causing less environmental impact.
Before embarking on projects that would likely impact historic properties, meeting specific environmental review requirements is indispensable, particularly Section 106 of the National Historic Preservation Act of 1966 (NHPA) and its equivalent state-level provisions, such as Section 14.09 of the New York State Historic Preservation Act of 1980.
Surveys can identify historic buildings that can be adapted for new uses while retaining their historic character. Adaptive reuse is inherently sustainable since it reuses existing resources and reduces the need for new construction.
Surveys can measure embodied historic energy audits. Simply put, embodied energy is the power required to extract, process, manufacture, and transport building materials. The fact that there is much-embodied energy in existing structures points out preservation as a sustainable activity.
Generally, historic preservation surveys involve several steps:
This initial phase involves gathering existing information about the area or specific property being surveyed. This includes consulting historical maps to understand past land use and development patterns and reviewing deeds and other legal documents to trace ownership and property history.
It involves on-site inspection to see and document the physical nature of the historic resources. The inspector takes notes of the architectural style, construction material, and more. Moreover, the professionals may even examine the interior and exterior elements of buildings along with the immediate surroundings and other archaeological features of landscapes. A direct investigation supplies firsthand data concerning the physical properties of the historic resources.
In this step, one has to visually record and write the historical resources. Photography will be done on an overall look at the resources and particular details about architectural features. In addition, detailed descriptions will be written describing the notable features of the resources.
When the field survey and documentation are done, the information gathered is evaluated to determine the significance of historic resources. In this, one assesses resources against established criteria, such as those used to list in the National Register of Historic Places. These criteria have factors such as architectural and resource integrity. This helps determine if the resources have met the thresholds for preservation and protection.
All findings are compiled in a comprehensive report. The historical context established during background research is included, and detailed descriptions and photographs from the field survey are included. Finally, the resources' significance is evaluated, and preservation or future management recommendations are made. Such documents provide a valuable tool for planning and future research involving historic resources.
It is an extremely tough and professional job to balance preservation with sustainability. Therefore, it follows some fundamental principles as listed below:
Generally, it is more sustainable to mend existing historic materials rather than replace them with new ones.
Materials compatible with the historic fabric will ensure the durable preservation of the building and avoid potential damage.
Applying heritage building energy efficiency upgrades to minimise the impact on historic character is a wise choice. This might involve installing insulation in inconspicuous locations, upgrading windows with historically appropriate storm windows, or improving HVAC systems with minimal alterations.
It involves assessing the environmental impact of materials and interventions over their entire life cycle.
Finding an appropriate resource to support surveys is vital to the success of a project. Find the most professional advice and execution in your historic resource inspections. Associating with a team of experienced professionals has the skills to conduct thorough surveys. By meeting all necessary federal and state requirements, including Section 106 and relevant state-level regulations, they can help you navigate the complexities of historic preservation.
