Windows: Materials, Methods, and Jobs-Boston – April 28-29, 2015
(Schedule as of February 11, 2015, subject to change)

Welcome to our 3rd National Windows Conference produced in collaboration with the National Park Service.

Windows are an important character defining feature of buildings. But, when they suffer from neglect and lack of maintenance, they present significant challenges for rehabilitation including cost, detailing, and return on investment. For additions to historic buildings or new construction, getting the details right is critically important for achieving the right look and long-term durability. We will examine wood, steel, aluminum, and bronze as we move further into preservation of 20th-century materials. Window work, from restoration of old windows to the design and installation of new windows, generates jobs and serves as an important economic engine. Join us for two days of demonstrations, discussions and direction about working with windows – historic, old and new, traditional, and mid-century modern.

1.75 AIA HSW Learning Units

Getting good verifiable data to document the performance of windows whether new or old is an important ethical consideration when advising clients about energy efficiency, climate response and durability. This session will provide an examination of contemporary standards, field testing, and laboratory analysis of windows.

Learning objectives for participants in this session include the following:

  • Apply industry standards and testing protocols for windows to both historic preservation and new construction projects.
  • Compare and contrast factors such as solar gain/loss; air tightness; infiltration; climate response, weather stripping and glass selection.
  • Use third party testing or self-directed field testing of windows.
  • Evaluate the performance of historic and new windows.

12:30 pm - 1:30 pm Lunch

1:30 pm - 2:30 pm TB1702 Managing Change: Getting the details right in window rehabilitation and replacement

Speaker: John Sandor, architectural historian, US National Park Service, Washington, DC
1 AIA HSW Learning Unit

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.

  • 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 often 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.

2:30 pm – 3:00 pm Break

3:00 pm - 4:30 pm TBC142 Trends in Wood Window Design and Manufacture

Speakers: Marvin Windows and Doors, Warroad, MN; Andrew Keefe, Green Mountain Windows, Rutland, VT, and others TBA
1.5 AIA HSW Learning Units

This session will feature brief presentations by leading manufacturers of wood windows on design matters, hardware, energy and code requirements, regulatory issues, and commercial pressures that drive the industry today. A Q&A session will follow the presentations.

Learning objectives for this session include the following:

  • Consider and apply the challenges of wood window design and manufacture to historic and traditional projects including but not limited to energy efficiency, minimal maintenance, ease of operation, code compliance, appearance and affordability.
  • Identify the advantages and disadvantages of the different approaches to installation and the products appropriate to each when working on historic buildings or historically inspired buildings.
  • Improve your ability to estimate costs and production needs for historic preservation and new projects.
  • Work with manufacturers’ representatives to design new windows that reflect important historical features for replacement on and additions to historic buildings and traditionally inspired new construction.
