"Here in the tropics, it's the shade not the stove that refreshes and brings people together," says Bruno Stagno about tropical architecture.
Guatemala ha estado construyendo su sombra a lo largo de los años. Nos encontramos con 3 ejemplos que proponen interesantes respuestas a este clima. Proyectos que materializan tanto grandes cubiertas con pendientes para dar sombra y evacuar el agua de lluvia con rapidez, como fachadas perforadas que permiten el ingreso de la brisa y la ventilación interior.
When designing homes, architecture is constantly evolving and adapting to environmental conditions. Each climate has specific needs and requires different solutions in terms of comfort. Hot and humid environments require a very different design from cold and dry environments. Natural ventilation, for example, is very important in projects located in warm climates.
Automation is everywhere around us - our homes, furniture, offices, cars, and even our clothing; we have become so accustomed to being surrounded by automated systems that we have forgotten what life was like without them. And while automation has noticeably improved the quality of interior spaces with solutions like purified air and temperature control, nothing compares to the natural cool breeze of mother nature.
But just like everything else in architecture, there is no one size fits all; what works in Tanzania cannot work in Switzerland or Colombia. This is due to several reasons, such as the difference in wind direction, average temperature, spatial needs, and environmental restrictions (or lack thereof). In this article, we take a look at natural ventilation in all its forms, and how architects have employed this passive solution in different contexts.
Ventilation serves two main purposes in a room: first, to remove pollutants and provide clean air; second, to meet the metabolic needs of the occupants, providing pleasant temperatures (weather permitting). It is well known that environments with inadequate ventilation can bring serious harm to the health of the occupants and, especially in hot climates, thermal discomfort. A Harvard University study demonstrated that in buildings with good ventilation and better air quality (with lower rates of carbon dioxide), occupants showed better performance of cognitive functions, faster responses to extreme situations, and better reasoning in strategic activities.
It is not difficult to see that ventilation plays a vital role in ensuring adequate air quality and thermal comfort in buildings. We have all felt it. But when we talk about ventilation, a light breeze from the window might come to mind, shifting through our hair and bringing a pleasant aroma and cooling temperature that brings fresh air and comfort. In mild climates, this experience can even be a reality on many days of the year. In harsh climates or polluted spaces, it could be quite different.
Patios and gardens play a crucial role in a project's planning and layout. In some instances, they serve as organizing elements while in others, they improve the quality of life in a space by providing light, ventilation, and a connection to the outdoors while maintaining the privacy of the inhabitants.
Nothing is more rational than using the wind, a natural, free, renewable and healthy resource, to improve the thermal comfort of our projects. The awareness of the finiteness of the resources and the demand for the reduction in the energy consumption has removed air-conditioning systems as the protagonist of any project. Architects and engineers are turning to this more passive system to improve thermal comfort. It is evident that there are extreme climates in which there is no escape, or else the use of artificial systems, but in a large part of the terrestrial surface it is possible to provide a pleasant flow of air through the environments by means of passive systems, especially if the actions are considered during the project stage.
This is a highly complex theme, but we have approached some of the concepts exemplifying them with built projects. A series of ventilation systems can help in the projects: natural cross ventilation, natural induced ventilation, chimney effect and evaporative cooling, which combined with the correct use of constructive elements allows improvement in thermal comfort and decrease in energy consumption.
This installation is a bespoke attempt to simplify and reinterpret the concept of air-conditioning, understanding that standardized solutions may not be universally applicable given the constraints of cost and surrounding environment. Using computational technologies, the team at Ant Studio has reinterpreted traditional evaporative cooling techniques to build a prototype of cylindrical clay cones, each with a custom design and size.
In response to the overwhelming growth of cities and neighborhoods in China, architects from Atelier Archmixing’s Shanghai office, have developed a series of proposals that seek to return value to sensitive interior spaces and improve the user’s quality of life through design.
The project consists of an interesting light fixture; a bamboo structure similar in shape to an umbrella, that lets natural light and fresh air into the building.
One of the great ironies of modern urban life is the underlying disconnect that exists amongst us global citizens, despite living and functioning within such dense and close proximities. In order to address this issue in the context of China’s urban landscape, New York firm NO ARCHITECTURE has proposed two alternatives to the typical high-rise – two vertical residential typologies that feature a combination of courtyards, terraces, and gardens, and could be located in a wide variety of cities.
“Conceived around a series of cascading shared walls, ventilated courtyards, stepped terraces, and wind towers, these new vertical organizations re-connect urban living to nature, suggesting how we can live in close proximity today and can continue to do so sustainably for generations to come,” explained the architects.
Professor Alan Short of the University of Cambridge has published a book advocating for the revival of 19th-century architectural ideas to address the crippling energy use of modern skyscrapers. The Recovery of Natural Environments in Architecture proposes an end to the architectural fetish for glass, steel, and air conditioning, instead drawing inspiration from forgotten techniques in naturally ventilated buildings of the 1800s. The book is a culmination of 30 years’ research and design by Prof. Short and his colleagues at the University of Cambridge.
With the goal of harnessing and exploring the benefits of clay as a raw material, which is characteristic of Colombia's Cúcuta region, Architects Miguel Niño and Johanna Navarro created Sumart Diseño y Arquitectura SAS, a studio that designs and develops sustainable architectural solutions.
One of their most successful projects is the Bloque Termodisipador BT, a ceramic block designed with an irregular cross section that allows ventilation to pass through the brick, reducing the amount of heat that enters the interior of the building.
