Sustainability

Designed with care for
the  people and the planet

Designed for life today, with tomorrow’s people in mind.
At Sian, we create sustainable modules that are as mindful of the planet as they are of the people who inhabit them. Our approach is based on a strong environmental ethic, aiming to preserve our planet through our building practices, foster a socially connected community, and maintain transparency in our governance.

Our dedication to the environment extends beyond our construction practices. We prioritize the development of a dedicated local workforce by integrating locally sourced materials and services into our production chain, including craftsmanship, furniture, finishes, and materials. We seek partnerships with businesses that share our commitment to ethical and sustainable production.

We believe in openness and accountability. As we move towards becoming a B Corp, we are dedicated to maintaining transparency in our governance model, ensuring that our processes meet the highest standards of social and environmental performance.
Reduced Carbon Emissions
The building and construction industry contributes substantially to global carbon emissions. At SIAN, our sustainable modules are designed to minimize environmental impact by reducing greenhouse gas emissions, supporting a more climate-conscious future.
Greenhouse emissions avoided with SIAN
Over its lifespan, a SIAN model* is expected to emit at least 2.10 tonnes of CO2 per year less compared to standard buildings of the same size and functionality. This significant reduction highlights our commitment to sustainable design and environmental responsibility.

This is equivalent to:
136

trees
08
tons of
oxygen
18
miles travelled in a commercial plane
8323
people breathing for an entire day
476
gallons of water evaporation
80
hrs. of cooling effect of 5 HVACs working

Energy efficiency

Slide 1

Energy efficiency

  • Incorporation of energy-efficient light bulbs and appliances with high energy ratings.
  • Utilization of passive solar and biophilic design principles.
  • High-level insulation on roofs, walls, and floors.
  • Double-glazed windows to minimize energy loss and gain.
  • Featuring air chambers in modules for active thermal regulation.
  • Adding terrace covers to prevent direct sunlight from entering the interior.
  • Designing suites with high ceilings to facilitate airflow.

Water Efficiency

Slide 1

Water Efficiency

  • Installation of water tanks starting from 2100 liters to conserve water and eliminate reliance on mains water.
  • Reduced water consumption in construction compared to traditional processes.
  • Efficient environmental management of wastewater.
  • Reduction of stormwater runoff.
  • Water-saving strategies such as low-flow faucets and showers, and dual-flush toilets.
  • Optional: Possibility of including a rainwater harvesting system.

Air Quality

Slide 1

Air Quality

  • We ensure the use of low VOC paints, varnishes, wood treatments, and wood products.
  • We strategically place windows for optimal air quality and cross ventilation.
  • Our interior finishes feature Viroc panels, a non-toxic, durable material made from recycled wood and cement.
  • Apart from wood, we use natural fibers for interior finishes, handcrafted by local artisan communities.
  • Our flooring is made from regional wood, reducing transportation costs and supporting the local economy.

Materials and sustainable finishings

Slide 1

Materials and sustainable finishings

  • We source sustainable plantation wood, preferably, when possible, of local origin.
  • We offer sustainable exterior cladding products known for their durability and low maintenance.
  • Our countertops are made from wood fiber from sustainable forests and reclaimed materials.
  • We adhere to strict environmental and social standards for our carpentry materials.
  • Our double-glazed windows have a five-star rating from the Window Energy Rating System.
  • We minimize waste during the construction process.
  • We design exterior and interior spaces separately to facilitate maintenance and possible replacement due to extreme environmental deterioration.
  • We recycle excess construction materials whenever possible.
  • Our wood coating leaves an “open pore” finish, allowing the wood to breathe, regulate humidity, and facilitate moisture release.

Passive Solar Design

Slide 1

Passive Solar Design

  • We prioritize passive solar design to create spaces that maximize natural light, utilize effective shading, and minimize dependence on artificial energy sources. Through strategic orientation, advanced insulation, optimized glazing, and airtight sealing, SIAN modules are designed to work with the environment, providing year-round comfort while reducing energy demands.

Waste Management

Slide 1

Waste Management

  • The compact design of each module minimizes wasted space, resources, and costs.
  • We use standardized panel sizes, reducing waste.
  • We recycle excess construction materials whenever possible.
  • We adhere to strict on-site guidelines to minimize waste and environmental disruption during delivery.
  • Our modular structure facilitates assembly and disassembly without the need for special machinery or tools.
  • Both the interior and exterior are designed in sections that can be easily assembled and disassembled, allowing the module to grow or shrink as needed.
  • We use clip or screw connections that enable easy disassembly and subsequent reuse.
Slide 1

Modular Architecture

Slide 1

Modular Architecture

  • Our constructions adapt to the needs of occupants, growing as families grow and changing according to life's various stages.
  • We avoid the use of heavy machinery.
  • Our construction times are significantly reduced due to our efficient modular design.
Slide 1

Ecosystem and biodiversity protection

Slide 1

Ecosystem and biodiversity protection

  • Our low-impact foundation system uses pilings, limiting excavation and earth movement.
  • We create specific spaces that protect local fauna and biodiversity.
  • Our architecture is designed to harmonize with the natural, cultural, and social environment, creating minimal visual impact and using vernacular design strategies (such as palm-thatched roofs in tropical areas, regional woods, and gabled roofs).
