In 1973, during the oil crisismany countries suddenly discovered that cooling buildings had become an energetic luxury. Bioclimatic architecture then returned to the center of the debate and many looked to old solutions: patios, thick walls, shade and cross ventilation. Curiously, decades before, an architect had already built houses following that logic, obsessed with something that today sounds strangely modern: that a home should offer serenity and refuge from the aggressiveness of the outside. Heat also enters through the eyes. For decades we have assumed that fighting the heat at home involves a almost automatic gesture: lower blinds and turn on the air conditioning. It is a mechanical, direct and, above all, solution. face. Long before that became the norm, the architect Luis Barragan Another idea was already working in Mexico City: that the temperature of a house does not depend only on its degrees, but on how the body perceives it. Its architecture, built between pink, yellow, blue walls and dense shadows, had spent decades exploring something that neuroarchitecture is beginning to support today: color, light and matter. alter physical sensation of space. They don’t cool the air, but they can cool the experience. House-Workshop of Luis Barragán Barragán understood the importance of color. In the Barragán’s workcolor was never decoration. Studies on his architecture show that he treated it the same as a wall or a window: as a structural tool of perception. Its pink, ocher or blue surfaces were designed to react to changing light of the day, transforming the depth, closeness and visual temperature of the space. A pink wall under the intense Mexican sun seems to radiate heat, while a deep blue patio prolongs the feeling of sky and distance. That rrelationship between color and light It was a central part of his work. The architecture moved with the sun, and with it the sensation of the inhabitant also changed. House-Workshop of Luis Barragán The house as a sensory laboratory. His best example remains the Luis Barragán Studio Housebuilt in 1948 and today protected by UNESCO. There everything is designed to modulate the bodily experience: thick walls, closed patios, interior gardens, water, darkness and color. UNESCO stands out precisely that deep dialogue between light, space and matter as one of the great contributions of the 20th century. The house is almost a manifesto of how a home can appeal to all the senses at the same time. Barragán saw it as a living organism, constantly evolving, and in that organism comfort did not depend on technology, but on balance. nterior of the Gilardi House, in Mexico City The half light as a refuge. Barragan distrusted of modern glass architecture and total transparency. While much of the 20th century celebrated large windows and abundant light, he argued for the opposite: the “half light”. He believed that human beings need spaces with shade and darkness to rest, think and concentrate. He said that too much light generates anxiety. In their houses, the windows are reduced, hidden or filtered with colored glass. The light never enters all at once; is dosed. This decision not only changes the emotional atmosphere, it also reduces the thermal load and softens the visual harshness of summer. It is an old and simple solution, almost forgotten in many contemporary homes. Patio of Barragan’s studio house The colors of the weather. The famous Barragán palette It did not come from an abstract theory. Its colors were born of the Mexican landscape. The pink of the bougainvillea, the red of the tabachin, the violet of the jacarandas, the ocher of the earth and the blue of the sky. Everything was part of a natural continuity between architecture and environment. In fact, the call “Mexican pink”developed together with the artist Jesús Reyes, became one of his most recognizable signatures. That color, present at the entrance to his studio or in patios like those of the Gilardi Housegenerates a feeling of calm and depth that continues to surprise those who visit it. Its architecture demonstrates that color can be an emotional regulator of space. Eduardo Prieto Lopez House Tradition already knew this trick. In reality, Barragán did not invent all this from scratch. Much of his work includes centuries of vernacular architecture in Latin America. Painted stucco houses, interior patios, thick walls and breathable materials were part of a climatic logic before electricity. Stucco, for example, allowed the walls they will breathe better in hot climates. Painting them prevented the glare of the white surfaces under the harsh sun. In many places, color not only gave identity, it also helped to better inhabit the heat. Barragán took that tradition and brought it to modern language. San Cristobal block Science explains it. Yes, because recent studies about emotional architecture and embodied perception help put words to what Barragán intuited. Today we know that light regulates circadian rhythms, affects mood and modifies thermal perception. We also know that certain colors can make a room feel cooler or warmer without changing its real temperature. The body first processes a sensory impression and then translates it into comfort or discomfort. Barragán worked precisely on that point. He designed spaces where perception and physiology intersected. An old idea for a new problem. Thus, in the era of air conditioning and skyrocketing thermometers, when cities overheat and energy consumption skyrockets every summer, Barragán’s architecture returns to read with other eyes. Their houses remind us that cooling does not always mean cooling the air. Sometimes means control the light, tame the shadow, reduce glass, use appropriate materials and choose a color well. Are slow solutionssilent and long before modern domestic technology. In that sense, his work seems less like an aesthetic relic and more like an open conversation with the present.
