Featuring a curvilinear form complemented by integrated wind towers and reinforced concrete, the design promotes passive ventilation and energy efficiency in a residential setting.
5 key facts about this project
01
Curvilinear design enhances solar gain management and passive cooling.
02
Integrated wind towers facilitate natural ventilation throughout the structure.
03
Reinforced concrete provides durability while allowing for unique geometries.
04
Ceramic tiles are used for both aesthetics and practical maintenance.
05
Strategic solar orientation optimizes energy use across seasons.

### Overview

Located in an urban setting, the project "The Formula" emphasizes sustainable architectural practices by integrating mathematical principles and organic forms into the design. The intent is to create an eco-friendly living environment that fosters a connection between urban architecture and the local ecosystem, addressing energy efficiency and occupant comfort through innovative solutions.

### Design Principles

#### Curvilinear Geometry and Environmental Integration

The project's most notable feature is its use of curvilinear geometry, which not only enhances the aesthetic appeal but also functions to optimize energy management. Curved surfaces are strategically designed to redirect solar radiation, mitigating direct sunlight exposure during peak hours and, consequently, reducing cooling costs. This design approach promotes a harmonious relationship with the environment by limiting ecological footprints.

#### Passive Climate Control Strategies

A key innovation within this design is the incorporation of four wind towers that channel breezes into the interior spaces, enhancing natural ventilation and improving air quality while minimizing reliance on mechanical cooling systems. Additionally, strategically placed courtyards facilitate cross ventilation, creating microclimates that maintain comfort and support environmental adaptation. The careful orientation of the building components further maximizes solar gain in winter and minimizes it in summer, thereby optimizing energy consumption throughout the year.

### Material Selection and Performance

The choice of materials reflects a balance between durability and aesthetic qualities. Reinforced concrete forms the structural framework, while extensive glass elements enhance natural lighting and energy efficiency. Lightweight aluminum features provide decorative details without compromising structural integrity, and ceramic tiles contribute to the cultural aesthetic of the interiors while allowing for easy maintenance. The overall design philosophy emphasizes both functionality and a visual connection to the surrounding environment, aligning with sustainable architectural goals.

The Buildner’s Unbuilt Award 2025: Celebrating Architectural Creativity and Visionary Unbuilt Designs with a Total Prize Fund of €100,000

`
Competition organisers

The Buildner’s Unbuilt Award 2025 is an international architecture competition dedicated to recognizing and celebrating the value of unrealized architectural designs. It invites architects, designers, and students worldwide to submit visionary projects that have not yet been constructed, highlighting the power of ideas and the creativity behind the design process. By focusing on unbuilt work, the competition aims to bring forward concepts that shape the future of architecture and push the boundaries of the profession. 

Participants can compete in three categories based on project scale: Small Wonders (up to 100 m²), Medium Marvels (101–999 m²), and Large Visions (over 1,000 m²). Each category winner will receive €20,000, and additional prizes include honorable mentions, student awards, and a special Best Presentation Award. Winning projects will gain significant international exposure through Buildner’s publicity campaign and a feature article on ArchDaily, providing a unique opportunity to showcase creative ideas to a global audience. 

The Buildner’s Unbuilt Award 2025 encourages entrants to submit any type of unbuilt project, from conceptual visions to detailed designs, celebrating bold innovation without the constraints of realization. Important deadlines: registration closes on October 30, 2025; submissions are due by November 20, 2025; winners will be announced on December 17, 2025.
