9:15 – 10:15 am Repairing Historic Wooden Windows: What Architects Need to Know

1 AIA Health/Safety/Welfare Learning Unit

Speaker: Brent Hull, Hull Millwork, Fort Worth, TX; craftsman, author and educator

While we usually take in the view of a whole building before we enter, windows are often the first architectural element which we observe at a distance. Like the eyes of a person, they often entice us to look more closely. They are very often important character-defining features of historic buildings. When working on historic preservation projects, they present challenges of energy efficiency, lead removal and maintenance planning. Their loss can be a deal-breaker if historic tax credits are part of the funding mix for your client’s projects. The craft of building, installing and maintaining good wooden windows is an important process for any building professional working on historic buildings or building new traditionally inspired buildings. Join a veteran woodworking craftsman for a master class that covers details common to historical styles, techniques and the importance of saving traditional wooden windows.

Learning Objectives:

  • Review the stylistic compositions and best craft practices that built traditional wooden windows.
  • Discuss craft detailing, storm windows and finishes that expand the life of windows in harsh climates.
  • Explain and specify best practices for installation, maintenance and repairs.
  • Plan for sound operation in high traffic areas particularly when working in historic residential, commercial and institutional settings.

10:15 –  10:40 Networking Break

10:40 – 12:00 pm Managing Change: Getting the details right in window rehabilitation and replacement

1 AIA Health/Safety/Welfare Learning Unit

Speaker: John Sandor, architectural historian, US National Park Service, Washington, DC

The Secretary of the Interior’s Standards for Rehabilitation are the underpinning for decisions on how windows will be treated in many projects. Though accommodating replacement where repair is unreasonable, the Standards require match. Judging what constitutes an adequate match requires a keen observation of a window in all its parts, an assessment of the varying significance windows can have to the overall character of a building as well as knowledge of the possibilities and limitations of the products available to us as replacements. This session will consider strategies for determining what aspects of a window are most critical for conveying an appropriate historic character and what we can expect to achieve with manufactured products.

Learning Objectives:

  • Identify the individual components that distinguish the various types of historic windows and discover the role each plays in the overall visual character of a window.
  • Distinguish the way materials affect dimensions and profiles of typical manufactured replacement windows.
  • Discover how the consequences of replacement in most cases bolster the argument for retention and repair yet understand how the language of the Standards accommodates useful flexibility.
  • Balance competing goals of retaining historic material and achieving a good match when choosing the approach for installing needed replacements; and select replacement windows designed for that approach.

12:00 – 12:55 pm Lunch

12:55 – 2 pm Metal Windows- Case Studies of Repair and Replacement

Metal windows are an important part of the history of windows, particularly when working on late 19 and 20 century historic preservation projects. When it comes to new, traditionally inspired work - whether residential, commercial, or institutional - metal windows have many advantages. The case studies will focus on repair, replacement, substitute materials, installation and maintenance. ​

Learning Objectives:

  • List several best building craft practices when repairing or replacing historic metal windows and installing new windows.
  • Identify the advantages and disadvantages of the different approaches to metal window installation and the products appropriate to each when working on historic buildings or historically inspired buildings.
  • Consider maintenance, ease of operation, and durability when evaluating historic and new metal windows.
  • Assess energy efficiency when repairing historic metal windows or replacing metal windows on historic preservation projects.

Tour Leaders: Kyle Sword, Business Development Manager, Pilkington North America, Toledo, OH

Union Station reopens to the public in September 2019 after extensive rehabilitation. A bus will take us to and from Union Station from Graylyn. This guided tour will discuss the details of the renovation and give participants the opportunity to investigate the building.

The station was built between 1924-1926 and was designed by Fellhimer and Wagner. Alfred T. Fellhimer (1875-1959) was the lead architect for Grand Central Terminal I n NYC. He designed numerous train stations throughout the United States including Union Station in Cincinnati. There will be presentations about the history of the building, Fellhimer and Wagner, and the rehabilitation process.

Please Note: Wear sturdy shoes for walking, the building is wheel chair accessible and please advise us if wheelchair accessible bus transportation is needed by contacting jhayward@aimmedia.com

Learning Objectives:

  • Explain the history of Alfred T. Fellhimer as an architect for some of the United States’ most important train stations of the 20 century.
  • Reflect on the frequent use of Beaux Arts architectural elements in American train stations of the early 20 century.
  • Discuss the transportation design history of Union Station.
  • List key aspects of the building’s recent rehabilitation such as codes, fenestration, preservation work and accessibility.

9:00 – 9:15 am Welcome and Introductions

9:15 – 10:15 am The Restoration of Stone Tracery for Stained Glass Windows- Ancient Craftsmanship/Modern Technology

1 AIA Health/Safety/Welfare Learning Unit

Speaker: Laurie Wells, Vice-President of Sales, B.E.S., M.A.; Old World Stone Limited, Burlington, Ontario

In 2017, a weather event known as a micro-burst impacted the First Presbyterian Church of Oklahoma City, causing its beautiful west window to bow inwards 16 inches, cracking or fracturing every stone tracery unit. 3-D scans were made of the damaged window to rebuild each piece using robotic milling, CNC routing and the manual talents of stone masons. Once shipped to Oklahoma City, these units were carefully installed by a local masonry contractor, and the new stone tracery window is now fully assembled. The south tracery window of First Presbyterian, also damaged in the micro-burst, is currently in production and will be discussed.

Learning Objectives:

  • Appreciate current processes for recording, cutting, and carving stone when both high-tech equipment and traditional hand tools are in use.
  • Improve the ability to accurately record field dimensions and sculptural detail for shop drawings and CNC programming.
  • Identify possible and potential applications for 3-D modeling for other tasks in architectural restoration work.
  • Assess the benefits and consequences of applying new technology to an ancient craft like stone carving.

2:05 – 2:15 pm Break

2:15 – 3:20 pm Windows: Conservation & Compliance - Window Repair & Replacement Projects

1 AIA Health/Safety/Welfare Learning Unit

Speakers: Richard W. Off, AIA, Senior Staff Architect, Hoffman Architects, Inc. and Rachel Palisin, PE, LEED AP, Senior Engineer, Hoffman Architects, Inc.; New York, NY

In addition to fulfilling the fundamental requirement of providing natural light and fresh air into interior spaces, windows play a key role in the defining the character and style of buildings. Restoring historic facades is  critical in both maintaining and potentially improving building envelope performance. Without proper assembly fabrication and installation detailing, windows are potential weak links within building enclosure systems, and they can easily become prime opportunities for air and moisture infiltration, thermal bridging, and structural distress. 

However, with ever more stringent building codes being established, especially energy codes, certain choices may already be made, especially on structures without official landmark designation. These competing forces generate the need for even more creative solutions, and some potential solutions will be explored in this presentation through a series of select case studies including a comprehensive window replacement project at a National Historic Landmark, early 20th century, Beaux-Arts style armory. As an active military facility, the replacement windows not only need to comply with specified air, water and structural requirements, but also blast-resistance criteria, creating the additional challenge of achieving high security with unreinforced decorative wood frame windows. This presentation will delve into the most relevant codes, essential testing procedures and critical details applicable to historic window replacements but will also examine the possibilities and limitations involved in the repair and retrofit of existing windows.

Learning Objectives:

  • Gain insight to make critical choices, such as having to balance competing needs by sacrificing one or more aspects of stylistic integrity in order to meet contemporary performance standards, or vice versa.
  • Apply lessons learned from a window project on a National Historic Landmark serving a high security function to other historic structures found in communities across the US.
  • Follow procedures to comply with contemporary energy codes.
  • Identify common problems and solutions with windows to design better building envelope performance.
  • Evaluate potential repair and/or retrofit options for existing historic windows when replacement is neither desirable nor possible.
