Geothermal Energy and Concrete Integration Define Sustainable Urban Housing

Project in-detail

Harnessing geothermal energy and incorporating a high-efficiency concrete envelope, the design achieves a net-zero energy goal while providing vital affordable housing in an urban context.
5 key facts about this project
01
Utilizes geothermal heat pumps for efficient climate control.
02
Features a high-efficiency concrete envelope for enhanced durability.
03
Incorporates operable curtain walls to optimize natural ventilation.
04
Design includes adaptable floor plans catering to diverse family structures.
05
Integrates public amenities to foster community engagement and interaction.
The NYC Net Zero Public Housing project is an architectural initiative located at 225 West 28th Street, New York City. This project focuses on providing affordable housing while prioritizing sustainability and energy efficiency. It addresses the ongoing challenge of housing shortages in urban environments, particularly for lower- and middle-income families. Through innovative design strategies and material applications, the project aims to demonstrate how modern architecture can contribute to community welfare without compromising environmental integrity.

Sustainable Features and Adaptability
The NYC Net Zero Public Housing project uniquely integrates energy-efficient systems and resilient materials in its design. The structure employs a high-efficiency building envelope made of concrete, which offers durability and thermal mass benefits. Surrounding the building, operable curtain walls enhance natural ventilation and daylighting, allowing residents to experience comfortable living conditions while minimizing reliance on artificial climate control.

Geothermal heat pumps further contribute to reduced energy consumption by harnessing the Earth's thermal energy. Solar panels on the roof generate renewable energy, guiding the building toward its net-zero energy target. The project’s commitment to sustainability is reflected in its material choices, such as rigid insulation that bolsters the thermal performance of the concrete shell.

Community Interaction and Public Spaces
The architectural design includes public amenities that foster community engagement, setting it apart from typical housing projects. A community bookstore and boutique clothing store located on the ground level serve as interaction points between residents and the larger urban context. These spaces not only provide functional benefits but also facilitate social connections, enhancing the overall quality of life for residents.

Adaptable residential layouts within the building cater to diverse family structures. By incorporating flexible floor plans, the design emphasizes livability and comfort, demonstrating a nuanced understanding of the needs of modern urban families. This focus on adaptability enhances the functionality of the project, allowing it to meet changing demographic trends.

Materials and Technical Solutions
The choice of concrete as the primary material underscores the project’s emphasis on durability and sustainability, while the implementation of high-efficiency solar panels and geothermal systems reflects modern technological practices. Passive design strategies, such as strategically placed balconies, are integrated to optimize airflow and reduce the reliance on mechanical systems, ultimately lowering operational costs.

The NYC Net Zero Public Housing project exemplifies a thoughtful approach to urban living that combines affordability, sustainability, and community building. For a deeper understanding of the project’s architectural plans, sections, and designs, we encourage readers to explore the complete project presentation. This analysis sheds light on how innovative architectural ideas can address contemporary housing challenges while promoting environmental responsibility.

Design a new small-scale home concept in the 10th edition of MICROHOME — 100,000 € prize + construction

Competition organisers

The 10th edition of the MICROHOME architecture competition invites architects and designers from around the world to explore the possibilities of compact, sustainable living. Hosted by Buildner in collaboration with Kingspan and Hapi Homes, this special edition challenges participants to design an off-grid, modular microhome for a young professional couple, with a maximum floor area of 25 m². Designs should prioritize innovation, efficiency, and real-world feasibility. 

A total prize fund of 100,000 € will be awarded, including three main prizes, the Kingspan Award, and the Hapi Homes Award, which will grant 15,000 € and lead to the construction of the selected design. The final registration deadline is September 25, 2025, and winners will be announced on Decebmer 9, 2025. For full competition details and submission guidelines, visit microhome.info.
