1245 Broadway (NoMad)

1245 Broadway, also referred to as the NoMad Project, is a 23‑story, boutique Class A office building located at the corner of Broadway and West 31st Street in Manhattan’s NoMad neighborhood. The project, designed by Skidmore, Owings & Merrill (SOM), delivers approximately 200,000 square feet of office space with ground‑floor retail and outdoor terraces integrated into a stepped massing strategy that recalls early 20th‑century Manhattan tower typologies while meeting contemporary performance expectations. 

Rather than employing a fully glazed curtain wall, SOM pursued a contextual concrete-and-glass façade that balances visual solidity with transparency. The envelope is composed of:

• Architecturally finished, poured‑in‑place concrete panels
• Deeply expressed punched openings
• Large, floor‑to‑ceiling triple‑glazed insulating glass units (IGUs)

This approach delivers high daylight penetration and expansive views while preserving a strong relationship to the scale, rhythm, and materiality of surrounding historic masonry buildings in NoMad. 

The curtain wall IGUs for 1245 Broadway were fabricated by Carey Glass, who supplied the project‑specific triple‑glazed units forming the primary transparent enclosure of the building. These assemblies were designed to optimize thermal performance, acoustic control, and visual clarity while supporting the project’s LEED and energy efficiency objectives. 

The insulated glass units incorporate Technoform warm-edge spacers, a hybrid stainless steel and thermoplastic spacer system, selected for both performance and aesthetic compatibility with the façade’s structural glazing expression. 

New York City’s Energy Conservation Construction Code (NYCECC), administered as part of the NYC Building Code, places strong emphasis on:

• Reduction of façade thermal bridging
• Improved whole‑assembly U‑factor performance
• Condensation resistance for high‑rise envelopes
• Long‑term durability of high‑performance enclosures

Warm‑edge spacer technology directly supports these objectives by addressing one of the most thermally vulnerable areas of glazing systems: the edge of glass.

At 1245 Broadway, the integration of Carey Glass–fabricated triple‑glazed IGUs with Technform’s warm-edge spacers delivers a façade system that balances architectural intent with rigorous thermal performance. The result is a high‑clarity, low‑energy envelope that supports NYC energy code compliance, enhances occupant comfort, and contributes to the building’s position as a next‑generation Class A office property in the NoMad district.
