Biodigester-Enabled Living Unit with Composite Panels and Water Generation Systems

Project in-detail

Equipped with an advanced biodigester and water generation systems, this unit utilizes composite panels for energy-efficient living while promoting sustainable food production and resource management.
5 key facts about this project
01
Equipped with an air water generator producing 300 liters of drinking water daily.
02
Incorporates a biodigester for efficient waste management and resource reuse.
03
Utilizes composite panels for enhanced energy efficiency and structural integrity.
04
Features a modular design for easy assembly and adaptability to various environments.
05
Supports on-site food production for fish and vegetables, promoting self-sufficiency.

The Global Sustainable Unit (GSU) is an ambitious design aimed at addressing the needs of modern living through a sustainable approach. Situated in diverse geographical contexts, it serves as a self-sufficient habitat that focuses on ecological responsibility. The unit combines multiple functions, including living spaces, food production, and energy generation, into a singular design. This integration promotes an efficient and practical way of life.

Modular Design

The GSU employs a modular design that enhances its practicality and flexibility. This structure allows for straightforward assembly and expansion, featuring a compact form similar to a suitcase filled with essential components. This thoughtful approach makes it suitable for various environments, whether in bustling cities or more remote areas.

Food Production Systems

Central to the GSU are its food production systems. Residents can grow fish and vegetables right within the unit, reducing dependence on outside food sources. This capability allows for a more self-sufficient lifestyle, giving individuals greater control over their food supply. The design supports sustainable living by encouraging fresh, homegrown produce.

Water and Energy Management

Water management within the GSU is efficient, using air water generator technology to produce around 300 liters of drinking water each day. Additionally, it features an 800-liter fountain for water storage. The energy aspect is covered by photovoltaic solar panels that generate 5 kilowatts and wind turbines that produce 1.6 kilowatts. These elements work together to ensure the unit can operate independently, with minimal impact on the environment.

Structural Integrity

The structure of the GSU is robust, using steel for its main framework to ensure durability and strength. PVC materials are included in the projecting windows to improve energy efficiency and lighting. Architectural composite panels are also integrated, offering a lightweight yet sturdy option that enhances the overall performance of the design.

The design of the GSU reflects a commitment to practical sustainability, focusing on resource efficiency and improving the quality of life. Its cohesive form and functional elements serve to create a living space that not only meets the needs of its occupants but also respects the environment.
