The battle at hand Can historic preservation
be squared with environmentally friendly
buildings? The sides appeared evenly matched.
At one point in the meeting, during a discussion
of windows, an attendee proclaimed that
environmentalists could rip the drafty wood
windows out of her historic building. "over her
dead body."
Balance
Prospects for peace appeared dim, .... until the
subject was examined more closely.

• Sustainable design
• Provide a healthy
• environment for the inhabitants -
• Good ventilation
• Natural lighting
• Use materials that are biodegradable, recyclable
  and made from renewable resources
• Consume less energy in new systems than market
  standards
• Have a recycling plan for waste and water
• Sustainable Design and Historic Preservation
• by Sharon C. Park FAIA.

• Historic buildings
• Have intrinsic value based on style,
  construction techniques, craftsmanship and
  setting
• Retain historic character and character defining
  features (i.e., windows)
• Retain significant historic materials
• Retain site and landscape features that
  contribute to the setting
• New additions must be sensitive in scale,
  character and design

19
Governing Standards
LEED (Leadership in Energy and Environmental
Design) Green Building Rating System is a
voluntary, consensus-based national standard

• The Secretary of the Interior's Standards for the
  Treatment of Historic Properties were codified in
  the July 12, 1995 Federal Register.
• 4 methods of treatment
• Preservation
• Restoration
• Rehabilitation
• Reconstruction

Secretary of the Interiors Standards and
Guidelines for Rehabilitation

Smathers Library Library East

• Constructed 1927
• East Wing Addition 1931
• North Wing Stacks Addition - 1946

23
Maintenance Issues

• Wood Frames Steel Sashes were deteriorated
• Broken Operators
• Cracked Glass Panes
• Conditioned air leaking out
• Air infiltration
• Reading Room now used for archival items

24
Project Approach

• Survey all windows to
• Identify character defining features
• Document condition of frames, glass, sash
  operators.
• Environmental Survey
• Asbestos
• Lead paint
• Architectural Restoration Documents
• Restore Windows Keep Library Functional

25
Removal

• Abatement of asbestos and lead paint Windows were
  removed.
• Openings were covered with plywood.
• Sealed to prevent water air intrusion.
• Library operational

26

• Each window frame was identified.

27

• Rusted steel frames to be cleaned, repaired and
  primed.
• Controlled environment
• of the shop.
• Operators were brass and steel.

28

• Final removal of lead and asbestos under
  controlled conditions

• Window frames to be restored

29

• Window frames under restoration

30

• Paint was removed to bare wood.
• Rotted wood was replaced.

31

• Existing glass

• Glass prepped for
• application of UV film.

32

• Re-installation of window frames and sashes.

33
Restored windows

• Constructed 1950
• Administration Bldg.
• Contributing Bldg. in the Historical District

36

• Existing Conditions

• Air sound intrusion
• Preservation of interior materials (marble)

37

• Multiple interior sill conditions

38

• Average air loss per window was 44 CFM.

Project Approach
Survey all windows to Identify character
defining features Document condition of frames,
glass, sash operators. Environmental

40
Checking Window Sizes

• Each window was measured and categorized so that
  replacement units would fit snugly in specific
  openings.

41
Checking Fit of Components

• Samples were brought in to assure fit over
  existing frames.
• Original window frames were retained to avoid
  damage to tile and marble window sills and
  plaster jambs and heads.

42
Mockup Installation

• Fit, appearance and compatibility are checked.

• New window near (below) existing.

43
Window Installation

• Building occupied through installation
• Assembly Trailer on site
• Windows were not removed unless they could be
  replaced the same day.
• Window being transported from the assembly
  trailer to its scheduled opening.
• Openings ready for windows.

44

• Consideration had to be given to ceiling
  conditions, furniture, scheduling to accommodate
  occupants, etc.

45
New Completed Windows
Benefits

• External Noise Reduction
• Air infiltration minimal
• Ultraviolet reduction
• Heat gain reduction
• Water infiltration eliminated
• Low E glass

46
Lobby Area

• Installation did not damage irreplaceable marble
