Between now and 2050, worldwide installation of cooling appliances, like air conditioning, is projected to triple, resulting in a twofold increase in energy consumption. This reliance on such devices, often seen as exacerbating global warming, poses a paradox: how can we fight rising temperatures in cities while simultaneously contributing to them through our dependence on these solutions?
The duality of sunlight in the field of architectural design presents fascinating contrasts, especially when addressing the question of how to interact with it through the built environment and the materials that define architecture. The sun's influence in this discipline has become an essential part of the cultural heritage of some countries, as evidenced by Spanish architecture, where the interaction with sunlight manifests through elements such as lattices. These lattices are recognizable on the facades of buildings from the Middle Ages, exemplified by structures like the Alhambra, to 20th-century constructions such as Casa Gomis, considered historical monuments.
The facade, being the skin of the building, is the architectural component that is usually directly exposed to sunlight. Based on this premise, we seek to establish a dialogue between openness to the environment and the need for protection, thus creating a synergy between functionality and aesthetics. In this context, sunscreen facades have been developed through various approaches, standing out for their ability to address this design condition. For this reason, we have selected solar control solutions from Spanish brands, distinguished by their technical characteristics and materiality through various approaches.
Shade refers to a region or state where sunlight is partially obstructed by objects or structures. This concept plays a crucial role in architectural design, as it significantly impacts comfort and functionality. It offers relief from direct sunlight, helps regulate temperature, and reduces glare. For these reasons, architects strategically incorporate shading elements to enhance the quality and utility of spaces, especially in outdoor residential areas. In this context, ShadeFX are manufacturers of innovative sun, rain and privacy solutions that are customized for every project regardless of size or complexity.
Whenever light falls on a surface there will be a shadow, no matter how insignificant its focus is. The outline will hardly be visible, but other shapes will come to the fore in this play of light and dark. In the case of being projected by solar dance, a latent dynamic is added to the shadows that can be used to intensify everyday phenomena, breaking the monotony of space. Orthogonal openings in a long corridor or woven pieces in a courtyard are examples of constructive elements that create patches of light and shadow, bringing in addition to aesthetic delight and thermal comfort to its users. In this way, it becomes evident that these intangible elements are essential parts of an environment that, long before Louis Kahn declared the power of shadows, was already being manipulated.
Traditional building solutions tend to work well in their respective contexts, as they have withstood hundreds of years of testing and improvements, and use techniques and materials available locally. Although globalization and the democratization of access to technology have brought more comfort and new opportunities to humanity, it has also led to the homogenization of solutions in the construction sector and a dependence on global supply chains for construction materials and components. This has also caused a rupture in how knowledge is passed on to new generations and, eventually, the disappearance of traditions.
In particular, the topic of passive cooling solutions for buildings is currently having a resurgence, with an effort to recover ancient techniques used throughout history in locations that have always had to deal with hot climates. This is even more evident due to the high energy costs imposed by artificial cooling, the global warming scenario, and mainly because, among the projections of population growth, a significant portion of megacities will be located in the predominantly hot climates of Africa and Asia. When we think about the future, is it possible to be inspired by the past and apply ancient cooling techniques to contemporary buildings?
Pantone has revealed its Color of the Year for 2023, 18-1750 Viva Magenta, a brand-new color "brave and fearless, whose exuberance promotes a joyous and optimistic celebration." The shade falls under the red family and is inspired by the tone of cochineal extract, one of the most precious dyes historically used to color textiles, cosmetics, and food.
Understanding how shadows will act in and around an area is a necessary understanding to ensure greater spatial quality. Shadows can influence natural lighting - therefore, the perception of space - and also issues of thermal comfort. Thus, mapping your projections and visualizing their movements during each season of the year can be fundamental to improve your project. The good news is that there are simple tools that help you visualize this in your city and in natural environments.
Pantone has revealed its Color of the Year for 2022; 17-3938 Very Peri, a brand new color "whose courageous presence encourages personal inventiveness and creativity". The shade falls under the blue color family but with violet red undertones, illustrating the fusion of our modern times and how the digital world has morphed with our physical one. In architecture, shades of periwinkle blue and lavender have long been used in installations, commercial spaces, and lighting, instilling an overall calming, optimistic, and positive effect on the human mind.
Although an architectural project comes to life with palpable materials, it is also defined by intangible qualities that give it richness, dynamism, and liveliness. Among them, the interplay of light and shadow can transform environments and affect their perception, determining the user's spatial experience. Besides providing natural ventilation, privacy, and thermal comfort, lattices allow this duality by filtering the entry of sunlight while projecting repetitive figures on the surface. In this way, perforated walls and ceilings can create multiple geometric patterns of light and shadow that become design elements capable of generating unique atmospheres.
"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.
