Report Final Guidance and Implementation of
NPSAB Recommendations (includes summary of NPS
flexibility on the specified topics)
5Interpreting 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. -
6Evaluating 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.
7Replacement 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.
8Documentation 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.
9Documentation Requirements for Proposed Window
Replacement - 2
10Identifying 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.
11Identifying 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
12Changing 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.
13Subdividing 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.
14Retaining 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.
15New 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.
16New 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.
17New 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.
18Codes 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).
19Energy 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.
20Evaluating 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.
21Very 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.
22Functionally 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
