Reglazing Modernism: Intervention Strategies for the Renewal of 20th Century Icons
The extensive use of exterior glazed enclosures is one of the most character defining features of Modern architecture. After decades of service, many Modern buildings from the pre- and post-war periods of the 20th century have deteriorated and have required various types of interventions to address decay, reestablish functionality and improve appearance or performance.

Reglazing Modernism – Intervention Strategies for 20th Century Icons by Angel Ayón, Uta Pottgiesser and Nathaniel Richards (Birkhäuser, 2019) presents twenty international case studies of culturally-significant Modern buildings in the US and Europe where the original steel frame window walls, curtain walls or ribbon windows have been intervened according to different criteria and with varying outcomes. The case studies presented in the book are organized according to three main intervention categories: Restoration, Rehabilitation and Replacement. These three main categories are expanded into further intervention strategies that portray a wide range of options for reglazing Modernism. Each case study is presented through a combination of historical analysis, technical evaluations and compelling graphics that include historic images, technical details and existing conditions photographs.

Conceived as a critical assessment instead of as a catalog or technical guide, the book presents a range of approaches to intervene on Modern steel frame glazed assemblies. It evaluates each case study in terms of how the intervention helped to preserve culturally significant features and how it adhered to current understanding of building science, Modern heritage conservation and contemporary requirements for building envelope design for energy conservation and optimum environmental performance. This is the first publication to present a wide range of international case studies with the purpose of delineating much-needed best-practices for intervening on culturally-significant Modern exterior glazed enclosures. The book also presents a set of emerging high-performance technologies that are becoming available in the building construction and renovation marketplace as a response to the challenges posed by some of the reglazing Modernism case studies included in the publication. Angel Ayón’s and Uta Pottgiesser’s presentation will be followed by a Q&A with Kyle Normandin.
