Sustainability Report

In this project, the strategy focused on sourcing natural and local elements while incorporating recycled content for specific elements:

• Local and Noble Materials: The house utilizes marble, stone, and local woods, reducing the carbon footprint associated with long-distance material transport (for the local woods and stone).

• Recycled Content: Recycled wood decks were used, providing a direct, measurable reduction in embodied carbon compared to using virgin timber for these elements.

• Durability over Lightweight: The selection of long-lasting materials such as concrete, stone, and marble emphasizes durability and structural permanence, which, while high in initial embodied carbon, extends the building's lifespan to reduce the carbon impact per year of use.

The project achieves low operational energy demand through a hybrid approach combining renewable technology and traditional passive design appropriate for the tropical climate:

• On-Site Renewable Energy: Integration of solar panels significantly reduces the consumption of grid electricity, which is the primary driver of operational carbon emissions.

• Passive Cooling: The use of cross ventilation naturally improves thermal comfort, drastically reducing reliance on energy-intensive air conditioning systems.

• Optimized Daylighting: Careful attention to orientation and sunlight exposure allows for efficient use of natural light, minimizing the need for artificial lighting, which is a major energy consumer.

• Water Efficiency: Water recycling systems are incorporated to optimize the use of water resources, reducing energy associated with water treatment and distribution infrastructure.

The core strategy for maintenance is longevity, minimizing the need for replacement and repair over the building's lifespan:

• Extreme Durability: The foundational materials—concrete, stone, and marble—were selected precisely because they are long-lasting and robust, greatly reducing the frequency of maintenance and replacement cycles.

• Low-Maintenance Systems: The reliance on passive systems (like cross ventilation and orientation) means less maintenance is required for complex mechanical and climate control equipment compared to a conventional, actively cooled mansion.
