Commission approves window master plan for 45 Tudor City Place, asks staff to review mullion thickness
Summary
The commission approved a master plan allowing multilite black aluminum casement windows at 45 Tudor City Place while asking the applicant to work with staff to reduce the apparent thickness of the new mullions and consider more historically compatible details where feasible.
The Landmarks Preservation Commission approved a window master plan for 45 Tudor City Place on Jan. 6, finding the proposed black-painted multilite aluminum casement units would match the historical configuration and operation while providing improved thermal performance.
Dane Barnes of BHK Engineering presented the proposal including 11 window types, HVAC options and details for through‑wall sleeves, insulated infill panels, and louvers. He told commissioners the new insulated units will "make the residents much more comfortable and allow their building to become more energy efficient." The application noted similar units have been approved and installed at neighboring Tudor City buildings.
Preservation groups urged caution. Manor/Manur Fatima of the Historic Districts Council said the project "has significant reservations about replacing the original steel casement windows with modern aluminum units," warning that bulk and finish can differ and that simulated surface muntins can be inappropriate. John Graham of the Victorian Society argued for refurbishing original windows and considering interior storms or thermally broken steel where feasible.
Staff told commissioners simulated divided lights can be approved at staff level under established criteria and that for large buildings an applied exterior grille may satisfy detail requirements. Commissioners unanimously approved the master plan with a motion that asked the applicant to work with staff to explore whether the thickness of the mullions could be reduced within the system and to ensure uniformity across the facade.
