Speaker: Giovanna Fernandes, Architect and Sales Associate, Architectural Glass Division, Pilkington North America. Giovana Fernandes is an architect and sales associate at Pilkington North America representing the Central Region. She advocates for advanced glass technologies like Vacuum Insulating Glazing to boost energy efficiency while preserving historic architecture, aligning with NSG/Pilkington’s mission as a global leader in innovative glazing solutions.
Description:
Windows and their glass are defining characteristics as a traditional building. By deconstructing the basic components (glass, coatings, and design), it is possible to better analyze and understand historic window restoration or repair. The basic levels of performance and aesthetic impact of window design will be described and detailed. This course details how vacuum insulated glazing (VIG) is made and how this differs from traditional glazing.
This course will detail some of the differences in VIG technology for window usage, seal, and construction. Case studies on how VIG has been used in historic restoration and key takeaway lessons from the projects will be discussed, including how the use of VIG reduces waste while improving energy efficiency
Learning Objectives:
- Understand thermal and sound performance factors related to window design.
- Identify alternatives for performance and aesthetics when faced with repair or replacement glass for historic preservation and traditional new products.
- Be able to explain the history and development of glass and insulated glass (IG) products as well as the impact on the internal environment of the building.
- Describe the properties and performance of vacuum insulated glazing (VIG) and other types of glazing and cite lessons learned from case studies of the use of VIG in historic buildings including the carbon impacts.
