Sustainability Report

Sustainability information provided by Mariana de la Mora Padilla, Architect at Di Frenna Arquitectos.

Embodied carbon overview

• The project was not developed under a specific international certification system. Instead, the design approach is grounded in a contextual and climate-responsive understanding of sustainability, rooted in local practices and environmental conditions.
• Material selection prioritised durability and low maintenance, reducing the need for replacement over time. The use of exposed materials such as concrete and steel eliminates additional finishes, reducing layers, waste, and resource consumption.
• The project emphasises material authenticity over branded systems. Most elements were developed through close collaboration with local builders, fabricators, and artisans rather than relying on standardised or industrialised products. Steel components, including walkways and structural elements, were custom-fabricated locally. The charred wood was treated using traditional techniques adapted on site, while the concrete was cast in place with carefully designed formwork to achieve the desired texture and expression.
• Locally sourced broken stone, extracted from a nearby quarry in the region, is used in the landscaping areas. It is selected for its natural texture and integration with the surrounding landscape.
• Construction processes relied on local labour and craftsmanship, reducing transportation impacts and supporting regional economies. 
• While not quantified in carbon metrics, these decisions contribute to a reduced overall environmental footprint.

Operational emissions overview

• At this stage, there is no quantified data regarding operational energy performance.
• The building operates primarily through passive environmental strategies. Natural ventilation, shaded courtyards, thermal mass, and controlled openings reduce reliance on mechanical systems. These strategies contribute to a stable indoor environment adapted to the local climate, lowering operational energy demand over time.

Maintenance overview

• Material selection prioritised durability and low maintenance, reducing the need for replacement over time. The use of exposed materials such as concrete and steel removes the need for additional finishes, reducing ongoing material use and maintenance requirements.
• Longevity and durability were central considerations throughout the design process. The use of exposed materials such as concrete, steel, and charred wood prioritises resilience and reduced maintenance.
• Details were developed to respond to local climatic conditions, including heat, humidity, and weathering. Materials are left exposed and allowed to change over time while maintaining structural and spatial integrity.
