Designed by Pieter van Dijk and completed in 1966, the Anthony J. Celebrezze Federal Building was in need of façade renovations in 2006 that would strengthen the building’s protective design and reduce its energy consumption. The result? A unique, secure glass curtain wall that provides enhanced security for building occupants and an expected 17% energy cost savings for the owner.
We provided structural design and protective design services to Interactive Design Architects for the renovation.
- The original façade was a glass and stainless steel curtain wall system.
- We also analyzed the existing superstructure and the new facade support system for the extreme thermal loadings developed during exposure during construction and within the double wall cavity when complete. Connections were developed, designed and sequenced to minimize the load demands on the existing superstructure.
- Installation of the new curtain wall outboard of the existing façade, together with over night construction, allowed work to be completed while the building remained occupied.
- The new curtain wall creates a double wall system, with a layer of air between the new and old walls that acts as insulation, reducing heating and cooling requirements to provide energy cost savings of about 17 percent.
