High-Performance Concrete Arcs with Energy Recovery Systems in Urban Redevelopment

Project in-detail

With cantilevered arcs crafted from ultra-high performance concrete and integrated energy recovery systems, the redevelopment revitalizes urban dynamics while enhancing community engagement.
5 key facts about this project
01
Cantilevered arcs create sheltered gathering spaces while enhancing structural aesthetics.
02
Energy recovery systems improve energy efficiency and reduce the carbon footprint.
03
Ultra-high performance concrete ensures durability while allowing for innovative design.
04
Integrated green spaces incorporate biodiversity into the urban environment.
05
Community involvement in the design process fosters a sense of ownership and connection.
Freedom Square in Kharkiv, Ukraine, is undergoing an architectural redevelopment project that aims to revitalize the public space while respecting its historical significance. This project integrates modern design principles with sustainable practices to create an inviting urban environment. The redevelopment is realized through a thoughtful arrangement of structures, public areas, and amenities, all designed to enhance accessibility and community engagement.

The project comprises various elements, including multi-functional arcs, pedestrian pathways, and infrastructure improvements that collectively foster a vibrant civic life. The central feature of the design is an expansive atrium, complemented by three distinct arcs: the Eternal Arc, the Infinite Arc, and the Reverence Arc. These arcs serve as focal points for social interaction and cultural activities, bridging the historical context of Freedom Square with contemporary urban needs.

Unique Design Approaches

One distinguishing feature of the project is the focus on community participation throughout the design process. The architects have engaged with local stakeholders to understand their vision for the space, ensuring that the redevelopment aligns with the needs and desires of the residents. The integration of transparent design principles allows citizens to feel a sense of ownership over the space.

Another notable aspect is the choice of materials. The project employs Ultra-High Performance Concrete (UHPC) and steel structures to ensure both durability and aesthetic coherence with the surrounding architecture. The use of double-glazed windows enhances energy efficiency while providing natural light to public spaces.

Sustainable energy solutions are incorporated through the use of solar panels on the arc roofs and an Energy Recovery Ventilation (ERV) system. These features greatly enhance the project's energy efficiency and reduce environmental impact, setting a standard for future architectural practices in similar urban contexts.

Architectural Details

The project's layout revolves around enhancing pedestrian flow and visual connectivity across the square, creating a seamless transition between the various public spaces. The canopies of the arcs not only provide shelter but also enhance the overall aesthetic by creating dynamic light patterns throughout the day. These details, along with the integration of green spaces, contribute to a more inviting urban atmosphere.

Moreover, the new infrastructure includes a tunnel that connects different areas of the square, demonstrating a commitment to improving accessibility. This feature addresses urban mobility challenges while fostering engagement among the community.

As this project unfolds, it represents a fresh approach to public space design, balancing historical preservation with modern architectural practices.
