Sustainability in architecture is no longer limited to selecting materials with a low environmental impact. Increasingly, professionals are taking a holistic approach to evaluating the performance of construction systems, including those elements that remain hidden once a project is completed.
Among these, installation substructures play a fundamental role, as they directly influence resource consumption, the project’s carbon footprint, transport logistics, installation efficiency, and the amount and type of waste generated at the end of the building’s life cycle.
In this context, innovation in installation systems has become one of the main opportunities to optimize the environmental performance of buildings. Reducing the quantity of material used, simplifying installation processes, and minimizing the overall weight of a system are strategies that make it possible to move toward more responsible construction without sacrificing the technical and aesthetic requirements of contemporary architecture.
The Hidden Impact of Substructures on Project Sustainability
When assessing the environmental impact of a ventilated façade or exterior cladding system, attention is often focused on the visible material. However, the substructure supporting these elements represents a significant share of the raw materials consumed by the overall system.
Aluminium, one of the most commonly used materials in these applications due to its durability and corrosion resistance, requires substantial amounts of energy during production. Therefore, any reduction in the quantity of aluminium used generates direct environmental and economic benefits.
Beyond the footprint associated with manufacturing, the weight of substructures also affects transportation, on-site handling and the loads transferred to the building. A lighter system enables optimization throughout the entire value chain, from production to end of life.
Designing More with Less: The Evolution Toward Simplified Systems
Technological advances in the construction sector are demonstrating that efficiency does not always depend on adding more components, but rather on designing smarter solutions. Simplifying construction systems allows redundant elements to be eliminated while maximizing the performance of each component.
In cladding fixing systems, this trend translates into the development of substructures capable of maintaining the same levels of safety, stability and durability while using less material. The challenge for technical teams lies in validating through testing and structural analysis that these reductions do not compromise long-term system performance.
When optimization is carried out correctly, the benefits are numerous. Resource consumption is reduced, installation becomes simpler, logistics costs decrease, and the overall sustainability of the project improves.
Weight Reduction as a Technical and Environmental Advantage
One of the most important factors in optimizing installation systems is reducing the overall weight of the construction solution. While this is often associated solely with transportation, its impact is much broader.
A lightweight system makes handling easier for installers, improves on-site safety conditions and helps accelerate installation times. It can also reduce structural requirements for the building, especially in renovation projects where existing load limitations are a significant constraint.
From an environmental perspective, weight reduction means lower transport-related emissions and reduced consumption of raw materials. This approach is fully aligned with circular economy principles, which seek to maximize resource efficiency throughout the product’s entire life cycle.
Innovation Focused on the Entire Life Cycle
The sustainability of a construction system must be analyzed from a global perspective. It is not enough to assess the impact of materials during manufacturing; transportation, installation, maintenance and end-of-life management must also be considered.
Solutions that reduce material consumption without affecting durability deliver significant improvements across all of these stages. Fewer materials mean less energy consumed during production, reduced logistical requirements and simpler management at the end of the system’s service life.
This holistic vision is particularly relevant for architects, specifiers and sustainability consultants, who increasingly require more detailed information about the environmental performance of the products and construction systems incorporated into their projects.
Parklex Prodema’s Commitment to More Efficient Installation Systems
Innovation in installation systems is part of Parklex Prodema’s continuous improvement strategy, focused on developing solutions that are increasingly durable, efficient and environmentally responsible.
One of the most significant developments in this area is the “Onesiding” project, an initiative that has enabled a complete redesign of certain substructures used for panel fixing. Traditionally, these solutions combined continuous aluminium rails with clip systems, resulting in high metal consumption and a significant increase in the overall weight of the assembly.
Following an extensive process of technical analysis and validation through testing, Parklex Prodema developed a substructure based exclusively on clips, completely eliminating continuous aluminium rails. Thanks to this optimization, the aluminium weight per panel has been reduced by approximately 80%, from 5.2 kg to just 0.89 kg per unit.
The company has also implemented further improvements in other existing systems by reducing the thickness of the aluminium rails used, without compromising installation strength or durability. This optimization has resulted in an additional 15% reduction in the total aluminium weight required.
These initiatives reflect Parklex Prodema’s commitment to innovation that goes beyond the visible product, targeting also the systems that make it possible. The objective is to offer solutions that combine technical performance, ease of installation and sustainability, helping to reduce environmental impact throughout the entire life cycle of a building project.
