Hudson Square Partnership is a joint venture with Hines, Trinity Church Wall Street, and Norges Bank Investment Management, that owns 12 buildings totaling 6 million square feet in the Hudson Square, Soho, West Village, and Tribeca districts.

The comprehensive retrofit of 345 Hudson Street takes advantage of tenant turnover from now to 2032 as an opportunity to upgrade the building’s infrastructure to new, carbon-efficient, energy cost-saving technology and completely decarbonize the 978,277 square foot property.

PROJECT DETAILS:

345 Hudson Street
New York City

$5 MILLION
NYSERDA investment

$30 MILLION+
of private investment

The floor-by-floor replacement of packaged terminal cooling units and steam heating with a comprehensive water source heat pump system significantly reduces heating and cooling needs by recycling heat from different spaces in the building. The water source heat pump system is accompanied by a new, highly efficient energy recovery ventilation system that minimizes energy waste.

Hudson Square Properties brought together a consortium of global solution providers and engineering expertise that took a solutions-based approach and adapted it to local market needs.

This project will demonstrate the power of thermal networking through an innovative approach by which heating and cooling is shared between tenants throughout the building and eventually between neighboring buildings. Heat will be stored by reusing defunct fire suppression tanks, which first reduces cost, but also allows heat pumps to operate more efficiently, matching heat delivery more closely with building operations.

“The carbon reduction and energy efficiency strategy at 345 Hudson, one of our flagship properties, exemplifies Hudson Square Properties’ stewardship and commitment to the long-term strength of our neighborhood. 345 Hudson will provide a roadmap for sustainable practices throughout our portfolio and beyond.”

The Empire Building Challenge

The Empire Building Challenge (EBC) is a $50 million investment by New York State to demonstrate different pathways for achieving carbon neutrality in tall buildings. Through the establishment of a private-public partnership with leading real estate owners and their engineering experts, exciting approaches to cold climate decarbonization are being tested in the New York market. The EBC’s new Retrofit Playbook for Large Buildings Link opens in new window - close new window to return to this page. includes step-by-step guidance and real-world case studies for decarbonizing and modernizing a range of building types. With the potential to replicate these solutions across real estate controlled by the first cohort of Empire Building Challenge partners and beyond, the impact of each project will accelerate New York’s progress toward the Climate Leadership and Community Protection Act’s (Climate Act) Link opens in new window - close new window to return to this page. goal of reducing greenhouse gas emissions 85% by 2050.
