Ecological, Lightweight, and Slender: Energy-Efficient Architecture with Translucent

In the contemporary context, global warming has marked a turning point in the way we think about architecture. We are witnessing record temperatures on our planet and a challenging panorama in many large cities, characterized by heatwaves and, in some cases, more severe winters. These circumstances have triggered a cycle in which the demand for heating and cooling systems increases, which, in turn, translates into higher energy and operating costs for buildings.

Given this situation, it becomes imperative to design energy-efficient buildings to reduce both the environmental impact and the associated costs. One of the strategies to achieve this is to properly plan the facade, which, serving a function similar to the building’s skin, can help reduce the energy required for heating and cooling. In this context, the polycarbonate panels developed by Rodeca contribute to the energy efficiency of buildings, in addition to their lightweight, slender construction, and translucent aesthetics.

Features and Architectural Applications of Polycarbonate Panels

Translucent building elements combine effective thermal insulation and translucency to create a striking visual appearance in architecture. Made of thermoplastic polycarbonate, the panels are particularly lightweight, making them suitable for retrofit projects of any scale or complexity. Their low weight also helps prevent any structural issues, and their co-extruded layer protects against UV rays, ensuring long life and durability. These panels find diverse applications, from interiors to exteriors, where they are especially suitable as facade and roofing solutions for industrial and commercial buildings.

The structure of the translucent building elements is composed of several layers that form air chambers acting as multi-level insulators, which reduce heat transmission. Depending on the specific project requirements and the energy demand in the building, it is possible to use panels that have from four to twelve layers. In this manner, the multi-layer structure effectively minimizes heat transfer through the facade. Furthermore, polycarbonate possesses a naturally low thermal conductivity in comparison to materials like glass or metal.

Technical Characteristics and Load-Bearing Structure

In a vertical installation scenario, the 60 mm thick translucent construction elements achieve a heat transmission coefficient (U-value) of 0.75 W/m²·K, reducing heat loss and contributing to a comfortable indoor environment.
