Global Holdings Retrofits 1250 Broadway With Energy-Saving Re-Cladding in NoMad

• Global Holdings upgrading 39-story Nomad Tower
• Replacing 2,000+ windows with high-performance insulation system
• Expected to cut energy use by about 20% and improve compliance

What the retrofit means for Nomad Tower

Renovation is underway at 1250 Broadway as Global Holdings upgrades the building’s exterior performance. Instead of a full façade replacement, the project focuses on replacing outdated windows with advanced insulation technology. This allows the owner to modernize the building while avoiding the higher cost and disruption of a full redevelopment. For landlords, this type of targeted upgrade is becoming a more efficient way to reposition office assets.

How the new technology improves efficiency

The building is installing a transparent insulation system that significantly outperforms traditional single-pane glass. The upgrade improves thermal performance while maintaining natural light. This is expected to reduce overall energy consumption by around 20 percent. It also helps the building move closer to compliance with New York’s Local Law 97 requirements. For investors, these upgrades can lower operating costs and improve long-term asset value.

Why sustainability is driving upgrades

Stricter energy regulations are forcing landlords to invest in building improvements. Instead of full redevelopments, many are choosing focused retrofits that deliver measurable results. This project shows how owners can meet compliance goals while maintaining building operations. It also benefits from utility incentive programs, helping offset costs. Sustainability is now a key factor in office competitiveness.

What this means for leasing and tenants

Energy-efficient buildings are more attractive to tenants, especially companies with sustainability targets. Improved comfort and lower energy costs can also support leasing performance. The property’s location near major transit hubs adds to its appeal, making it competitive with newer developments in Midtown.

What to watch next

Construction is already in progress and is expected to be completed this summer. If successful, this approach could be replicated across other older office buildings in Manhattan. As more landlords look to balance cost and compliance, targeted retrofits like this will become more common
