20 & 30 Hallets Point

Set along the East River waterfront in Astoria, Queens, 20 & 30 Halletts Point transforms a former industrial site into a vibrant residential community. Atelier Ten worked with The Durst Organization to embed sustainability at every level setting a new standard for sustainable and resilient living on New York’s waterfront.

20 & 30 Hallets Point demonstrates how large-scale developments can deliver environmental benefits to support health and wellness for residents and communities. The Halletts Point campus development introduces a community supermarket, retail spaces, fitness facilities, and a public waterfront esplanade with revitalized outdoor spaces designed to enhance livability and access to open spaces.

To enhance occupant well-being, Atelier Ten worked with Handel Architects, Starr Whitehouse Landscape Architects, and the Urban Atelier Group and the project team to implement Durst’s Sustainable Materials Criteria, ensuring healthier, low-impact products were used throughout the development. To support this effort, Atelier Ten managed a comprehensive materials database that will serve as a reference for future projects, and help to shift industry standards toward transparency, responsibility, and innovative use of low-carbon materials.

Life cycle analysis (LCA) during design specifically informed pathways to reduce carbon emissions in the steel and concrete packages. As verified with the as-built LCA, a 19% GWP reduction was achieved. And in total, the structure and enclosure emissions were limited to 406 kgCO2e/m2.

Resource efficiency was a critical focus. The development features an on-site energy plant that was designed to reduce annual energy costs by 36%. By capturing and reusing waste heat, the system achieves nearly 81% reduction in heating demand, significantly lowering greenhouse gas emissions. Water conservation strategies complement these energy savings. Efficient fixtures and the blackwater treatment system further reduce potable water use by 56%, closing the loop on resource efficiency. These water strategies contributed to 42% indoor water use and 51% outdoor water use reductions.
