With its quantifiable objectives and measurable performance, sustainability often passes as a technological challenge. Its primary language is that of data, equipment, and engineered systems, most often translated into a hyper-technologized layer hidden within a design upholding pre-existing aesthetic norms. As architecture is the image of society at one moment in time, how does the focus on sustainability translate into architectural language, further legitimatizing the efforts to establish an equitable relationship with the environment? Architecture serves as an expression of attitudes, and since sustainability has become a fundamental value, it is worth looking at whether or not it has produced an aesthetic transformation.

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.
