NPSAB Recommendations (includes summary of NPS
flexibility on the specified topics)
5
Interpreting and Applying the Secretary of the
Interiors Standards for Rehabilitation
  • Project meets Standards when overall effect of
    all work is consistent with propertys historic
    character, even when some individual features may
    not have been given recommended treatments.

6
Evaluating Historic Windows for Repair or
Replacement
  • Other factors may be considered, in addition to
    deterioration, in determining that historic
    windows may be replaced.
  • Historic windows that do not meet safety
    requirements may be replaced with matching
    windows.
  • Replacement of very small percentage of total
    number of historic windows does not need to be
    justified by deterioration.
  • A full window survey is not required to document
    deterioration.

7
Replacement Windows that Meet the Standards
  • The more important a window is, the more critical
    it is to match
  • Primary facades, 3 stories or less.
  • Primary facades, base of high-rise.
  • Existing windows that are not historic may be
    replaced with compatible new windowsthese new
    windows need not replicate missing historic
    windows.
  • Substitute materials may generally be used for
    replacement windows on secondary elevations of
    buildings, and above the base on all elevations
    of tall buildings.

8
Documentation Requirements for Proposed Window
Replacement
  • Clear photos of existing windows.
  • Same-scale drawings (with measurements,
    materials)
  • Elevations, horizontal and vertical sections of
    existing windows.
  • Elevations, horizontal and vertical sections of
    proposed replacements.
  • Small projects, windows with simple design cut
    sheets may be acceptable.

Identifying Primary and Secondary Interior Spaces
in Historic Buildings
  • Primary spaces essential in conveying the
    historic character of a building.
  • Secondary spaces less critical in defining a
    buildings importance because of size, location,
    or function.

11
Identifying Primary and Secondary Interior Spaces
in Historic Buildings - 2
  • Guidance on primary and secondary spaces within
    certain building types
  • Houses, rowhouses, duplexes
  • Apartment Buildings and tenements
  • Shotgun houses
  • Schools
  • Factories, industrial buildings and warehouses
  • Fraternal and lodge halls
  • Commercial office buildings
  • Churches
  • Hotels
  • Hospitals

12
Changing Secondary Interior Spaces in Historic
Buildings
  • Secondary spaces offer more opportunities for
    change and alteration
  • May be subdivided vertically (new walls) or
    horizontally (new floors, mezzanines).
  • New floor openings may be introduced.

13
Subdividing Assembly Spaces in Historic Buildings
  • Public assembly spaces, such as auditoriums and
    ballrooms, usually most significant spaces.
  • More opportunity for change is provided where
    finishes and features are seriously deteriorated
    or missing, or where space has already been
    significantly alteredsurviving historic
    character must be maintained, but such spaces are
    never required to be restored or reconstructed.
  • Opportunity for alteration or subdivision is
    provided in treatment of assembly spaces that are
    not primary, or are secondary to other assembly
    spaces in same building.

14
Retaining Corridors and Other Circulation Spaces
in Historic Buildings
  • Corridors almost always primary spaces.
  • Opportunity for change provided through
    shortening or truncating corridor ends.
  • More opportunity for change where integrity of
    corridors was previously eroded.

15
New Additions to Historic Buildings
  • Evaluating new additions in accordance with
    Standards 9 and 10
  • Historic buildings form/envelope, materials and
    features must be preserved.
  • Addition must be compatible (massing, size,
    scale, features, location).
  • Addition must be differentiated from historic
    buildingStandards do not dictate style so long
    as compatibility is achieved and historic fabric
    is preserved.

16
New Additions to Historic Buildings - 2
  • New additions in densely built environments,
    urban historic districts
  • May be opportunity for larger addition when
    façade of addition can be broken up into elements
    consistent with scale of historic building and
    surrounding structures.

17
New Construction within the Boundaries of
Historic Properties
  • Propertys historic function and setting must
    remain evident.
  • Compatibility of new construction viewed in a
    wider context, and may allow greater size and
    design flexibility the further away the new
    construction is from historic buildings.

18
Codes and Regulatory Requirements for
Rehabilitating Historic Buildings
  • Evaluations for code and other performance
    requirements must be done on a building-by-buildin
    g basis. NPS continues to encourage early
    consultation to ensure that proposed
    modifications comply with both code requirements
    and the Standards.
  • NPS will continue to work with national
    code/regulatory organizations and preservation
    organizations to seek solutions that promote
    preservation of historic materials and features
    (performance-based requirements).

19
Energy Efficiency, Sustainability, and Green
Building Practices in Historic Buildings
  • Rehabilitating a historic building, rather than
    constructing a new one, reflects philosophy of
    environmental sustainability and green building
    practices.
  • NPS will continue to work with consortium to
    re-evaluate Leadership in Energy and
    Environmental Design (LEED) requirements in
    context of historic buildings and the Standards.

20
Evaluating Substitute Materials in Historic
Buildings
  • If original material is too deteriorated to
    repair, compatible substitute material may be
    acceptable.
  • New technologies will likely lead to improvements
    in appearance and performance of substitute
    materials.

21
Very Large and Diverse Historic Properties Listed
in the National Register as Historic Districts
  • Very large historic properties, such as military
    bases, will be treated as historic districts,
    allowing NPS to review distinct usage-related
    groupings as functionally related buildings.
  • Each grouping, along with associated site and
    environment, will be considered single project
    (further defined by ownership parcel).
  • Long-term lessees will be treated as owners.

22
Functionally Related StructuresGeneral Criteria
  • Select criteria on specific property types
  • Industrial sites
  • Commercial properties
  • Domestic properties
  • Apartments, public housing and other multi-family
    housing
  • Military bases, university campuses, medical and
    corporate campuses
