TOSTEM Carport SC & PremiAL®: Minimalist in Design, Sustainable in Material

The beauty of a building begins with considered choices — from lines that harmonize with the architecture to materials that bring value for the future.

1. Considered Choices for Exterior Spaces

The beauty of a building begins with carefully considered choices — from design lines that harmonize with the overall architecture to materials that deliver sustainable value for the future.

In villa exterior spaces, a carport does more than just protect vehicles from the elements; it serves as a bridge between the home’s architecture and the surrounding landscape. The combination of the TOSTEM Carport SC and LIXIL’s PremiAL® low-carbon recycled aluminum delivers a refined exterior solution: preserving the sleek elegance of its design language while embodying a commitment to environmental responsibility.

2. PremiAL® — LIXIL’s Low-Carbon Recycled Aluminum Solution

According to data from the International Energy Agency (IEA) and the World Business Council for Sustainable Development (WBCSD), the building sector currently accounts for up to 37% of global CO₂ emissions. Against this backdrop, modern architecture is shifting dramatically from merely managing operational energy to reducing Embodied Carbon — the emissions generated throughout the extraction and manufacturing of building materials.

At the core of LIXIL Group’s carbon reduction strategy is PremiAL® — a low-carbon recycled aluminum line standardized on a global scale. Key facts that underline the prestige of PremiAL® include:

• Nearly 30 Years of Technological Innovation & Circular Recycling Solutions for 2050: According to the Japan Aluminum Association, global demand for aluminum is projected to increase by more than 1.5 times by 2050. Although aluminum can be recycled endlessly, the recycling rate in the construction industry currently sits at only around 10% due to technical barriers. Backed by nearly three decades of high-tech processing research, LIXIL is a pioneer in Japan to mass-produce 100% recycled aluminum billets with mechanical strength and surface quality equivalent to prime aluminum, officially realizing a closed-loop recycling model for the exterior industry.

• 97% Energy Savings in Production: Extracting primary aluminum from bauxite ore requires a massive amount of electrical energy. In contrast, smelting and recycling aluminum scrap consumes only about 3% of the energy needed for new ore-based aluminum production (saving up to 97% in energy consumption).

• 50% to 80% Reduction in CO₂eq Emissions: Depending on the proportion of recycled aluminum in the alloy, PremiAL® significantly reduces the carbon footprint of each extruded aluminum product. The PremiAL Standard line (containing over 60% recycled aluminum) achieves an emission level of 7.1 kg-CO₂eq/kg of aluminum (~50% CO₂eq reduction); PremiAL R70 reduces CO₂eq by ~55%; and PremiAL R100 (100% recycled aluminum) reaches 2.9 kg-CO₂eq/kg of aluminum (up to ~80% CO₂eq reduction) compared to primary ore aluminum.

• International SuMPO EPD Certification (ISO 14025): The Life Cycle Assessment (LCA) data for PremiAL® aluminum has been independently verified and awarded the Sustainable Materials and Products Program EPD (SuMPO EPD) certification in compliance with international standard ISO 14025 (Type III Environmental Declarations). This provides a transparent foundation that helps green building projects earn points toward LEED, LOTUS, or EDGE certifications.

• Mass Production Across 5 Global Plants: LIXIL has established a synchronized mass-production system for PremiAL® aluminum across 5 global extrusion plants (including Thailand, Vietnam — the LIXIL VINA plant in Dong Nai, Oyabe, Shimotsuma, and Ariake). This enables low-carbon aluminum to become a large-scale manufacturing standard without passing on additional costs to consumers.

3. TOSTEM Carport SC: The Refined Intersect of Design and Sustainable Materials

Alongside the environmental value of PremiAL® aluminum, TOSTEM Carport SC makes a striking impression through a minimalist design language focused on functionality and seamless integration with the overall architecture of the home. The product fully embodies three essential Eco-Luxury aspects:

3.1 Streamlined “Noiseless” Design

An ultra-thin aluminum roof measuring just 40 mm features sleek, flat lines. All connecting screws, brackets, and secondary hardware are completely hidden inside an internal interlocking structure. The gutter system and drainage channels are seamlessly integrated inside the column core, keeping the product’s appearance clean and visually uncluttered.

3.2 Engawa Philosophy: Connecting with Nature

Inspired by the traditional Engawa buffer space in Japanese architecture, the area beneath the Carport SC roof serves as a natural transition zone between the home and the garden. It provides a peaceful spot where homeowners can pause, relax, take in the fresh air, enjoy a cup of tea, or watch the rain — all while remaining comfortably protected.

3.3 Optimized Long-Term Performance

In addition to the PremiAL® aluminum material, the product surface is treated with TOSTEM’s exclusive TEXGUARD® Anodized coating technology. This electrodeposition (ED) coating blocks UV rays, retains color durability, resists dirt accumulation, and effectively combats corrosion under harsh weather conditions. Thanks to the material’s exceptional longevity, the structure maintains a consistent aesthetic over time, minimizing the need for routine annual maintenance or repainting.

4. Conclusion & Solution Discovery

The TOSTEM Carport SC alongside the PremiAL® recycled aluminum line embodies LIXIL’s commitment to sustainable development: delivering everyday comfort through refined, environmentally friendly design solutions. The combination of minimalist lines and material durability ensures the structure retains both its functional and aesthetic value for years to come.
