Our forefathers had a deep, instinctive wisdom when they embraced the circle. Their choice of circular huts spoke volumes about their understanding of harmony with the world around them. As they nestled into their rounded homes, they found themselves in spaces that flowed with the natural curves of life—spaces that invited the whisper of the wind to pass by gracefully, that harnessed the power of nature's gentle ventilation.
The curves of these structures provided resilience against the storms that raged, whispering secrets of resilience and strength. The simplicity of the circular form maximized warmth and energy, creating sanctuaries that comforted the body and spirit.
In our quest for modernity, we often default to square and rectangular blocks, but the soul of the circle endures. It's a call to reconnect with the essence of the past, to remember the wisdom of circular harmony our forefathers knew so well. Let us rethink our structures, embracing the beauty and sustainability of the round as we design for the future.

Introduction:
In the world of architecture and building design, traditional square-based structures have been the norm for centuries. However, there is an increasing interest in exploring and rethinking building morphology, particularly in temperate climates. Circular-based structures offer a range of benefits that square-based designs cannot provide, especially in terms of ventilation, wind resistance, and sustainability.

This comparative study will focus on the advantages of circular-based structures over square-based ones and explore the potential for sustainable departures from the standard square-based plans.
Air Flows and Ventilation
In temperate climates, effective ventilation is crucial for maintaining comfortable indoor temperatures and air quality. Circular structures provide natural and efficient air flow due to their shape. Air can flow smoothly around the entire circumference of the building, allowing for better cross-ventilation and circulation. This design helps in reducing the need for artificial cooling systems and enhances the comfort of the inhabitants.

On the other hand, square-based structures often struggle with air flow due to their sharp angles and corners. These corners can create stagnant areas where air does not circulate as effectively, leading to uneven ventilation and potential pockets of stale air. This can make square-based structures less efficient and less comfortable in terms of natural ventilation and indoor cooling for human comfort.

Wind Load Dissipation
Circular and spherical structures offer a significant advantage in dissipating wind loads compared to square-based structures. The curved surfaces of circular buildings allow wind to flow smoothly around them, reducing the pressure on any one area of the structure. This can prevent damage to the building, as the wind load is evenly distributed around the structure.

In contrast, square-based structures act as windbreakers, creating points of high wind pressure on flat walls. This can lead to roof uplifting and even partial wall collapse in extreme weather conditions.

Circular buildings, therefore, offer superior resilience to wind loads, making them a more reliable choice in temperate climates prone to storms or high winds.

Other Advantages of Circular-Based Structures
1. Energy Efficiency:
Circular structures often have better thermal performance due to their shape, which reduces heat loss and gain through the walls. This can lead to energy savings in heating and cooling the building.
2. Aesthetic Appeal:
Circular and spherical designs offer a unique and visually striking aesthetic that can enhance the architectural landscape. This can add value to properties and create more engaging spaces.
3. Space Utilization:
Circular buildings can maximize interior space by eliminating corners and making rooms feel more open and connected. This can lead to more efficient use of space.
Sustainable Departure from Square-Based Plans
To encourage a departure from square-based plans, architects and builders can focus on integrating circular-based structures in new projects. This shift can be achieved through the following strategies:
- Education and Awareness:
Educating architects, builders, and clients about the benefits of circular structures can promote their adoption.
- Incentives for Sustainable Building:
Governments and organizations can offer incentives for building circular structures that prioritize sustainability and efficiency.
- Research and Development:
Ongoing research into materials and construction methods for circular structures can help reduce costs and improve accessibility.
- Integration of Technology:
Utilizing advanced modeling and design software can facilitate the creation of circular buildings that are both functional and aesthetically pleasing.
Conclusion
Circular-based structures offer numerous advantages over square-based ones, particularly in temperate climates. From efficient ventilation and wind load dissipation to energy savings and aesthetic appeal, these structures present a compelling alternative to traditional building designs. By rethinking building morphology and embracing circular and spherical designs, architects and builders can create more sustainable, resilient, and attractive buildings for the future.
