Energia solar: The Latest Architecture and News

Architecture can no longer be thought of as an isolated object, detached from the technical networks that sustain contemporary life—a scenario that demands different readings and approaches. Against this backdrop, in March, ArchDaily's monthly topic focused on The Technosphere: Architecture at the Intersection of Technology, Ecology, and Planetary Systems, a broad and inevitably complex topic. Stemming from the concept of the technosphere, coined by geologist Peter Haff to describe the collective artifacts produced by humanity, a panorama emerges in which contemporary life is deeply intertwined with machines, data, and energy grids.

When delving into the envelope of construction and examining how the interior relates to the exterior, the concept of greenhouses emerges as an opportunity to cultivate life indoors, whether dependent on external factors or not. Defined as spaces enclosed by glass or other transparent plastic materials, greenhouses facilitate the growth of vegetables and ornamental plants even during periods of adverse external weather conditions. However, what does designing for plants involve? Climate, species, structural design, and the type of covering are just a few of the considerations to take into account.

Autonomy and freedom during the design process are invaluable resources for architects, especially when defining a volume and choosing materials, systems, and solutions for a building. The flexibility of these elements must not only promote their harmonious integration within a structure but, above all, allow architects to incorporate them without the need to change their initial concepts. This design freedom becomes even more crucial in the context of facades, specifically in building-integrated photovoltaic (BIPV) facades. This is due to the unique challenge of incorporating the energy capture function into the design of the building envelope, simultaneously demanding adaptation to the designer's aesthetic preferences and effective performance, as well as the entire infrastructure for capturing and transporting energy.

Traditionally relegated to roofs, photovoltaic (PV) panels tend to have a uniform appearance: large black or dark blue rectangular pieces of shiny glass with metal frames. Partly because dark colors better harvest sunlight to be turned into electricity, but also because silicon –the primary material used in most high-efficiency photovoltaic panels– tends to be dark in its crystalline form. Fortunately, there are now technologies to control luster, color and finish that provide aesthetic variety while maintaining high efficiency. SolarLab and other manufacturers are redefining conventional solar panels, introducing design flexibility and material qualities that allow architects to take advantage of large facade surfaces to generate renewable energy without compromising architecturally.

Including sustainable strategies in architectural projects is not just a trend, it is a necessity. Each day we become more aware of the importance of responsibly managing natural resources and understanding the environmental factors involved in designing a project.

Solar energy is one of the most commonly employed strategies in residential architecture, both active and passive. Many countries around the world offer incentives to encourage the use of solar systems, and the benefits of installing these systems can be seen in a short period of time, with a reduction of up to 95% in the monthly energy expenses, which makes this strategy one of the most attractive of all sustainable solutions. Furthermore, the average lifespan of a solar panel is 25 years, operating entirely on its own and requiring only basic cleaning once a year.
