UWCEA Boarding House in Arusha: Sustainable Living by Triple A Architects

Triple A Architects, renowned for their commitment to sustainable design, has made its mark on Tanzania with the remarkable UWCEA Boarding House in Arusha.

The UWCEA Boarding House is a unique and iconic series of buildings that not only enhance the cultural experience for incoming international students but also exemplify sustainable design principles.

Developed as part of the newly accredited UWCEA program, the project aimed to expand the school's existing campus facilities to include boarding housing, staff housing, an examination hall, science laboratories, and a canteen.

The architectural design drew inspiration from Maasai boma principles, creating a circular enclosure of sleeping quarters centered around a pavilion. This design not only embraced cultural heritage but also fostered a sense of community among the students.

An essential aspect of the UWCEA Boarding House is its commitment to sustainability. The dorm units incorporate numerous green principles, including rainwater harvesting systems that collect water from the roofs of the dorms and pavilions.

This harvested water serves various purposes, such as irrigation and flushing toilets, promoting water conservation, and reducing the dependence on traditional water sources. Additionally, solar heaters are installed to provide hot water, utilizing renewable energy and minimizing the carbon footprint of the boarding house.

To combat the African heat and ensure comfortable living conditions, the dormitories were strategically designed with openings that allow for natural ventilation. This design feature maximizes airflow, reduces the need for artificial cooling, and promotes energy efficiency.

Moreover, the incorporation of recycled plastic furnishings not only adds a touch of creativity to the dormitories but also educates students about the importance of upcycling and recycling.

The architectural approach of the UWCEA Boarding House aligns with the school's ethos and vision. It aimed to create a low-cost and energy-efficient series of buildings that serve as a supportive learning environment while showcasing innovative and intelligent functionality.

The circular enclosure design, reminiscent of the Maasai boma, reflects the belief of UWC in bringing together students from diverse backgrounds based on their shared humanity.

Furthermore, the UWCEA Boarding House serves as a beacon of sustainable building development in low-tech environments. It showcases the use of simple and traditional building materials and methods while incorporating contemporary architectural language.

The integration of recycled glass bottle walls in the bathrooms and toilets adds both aesthetic appeal and a practical demonstration of resourcefulness.

The UWCEA Boarding House has garnered international recognition for its exceptional design and sustainable features. Voted as the best boarding house among all 18 UWC schools on four different continents, it stands as a testament to the successful integration of cultural heritage, sustainability, and educational excellence.

The Bosco Verticale (Vertical Forest): A Green Oasis in Milan

Although not located in Africa, the Bosco Verticale serves as an inspiration for sustainable architecture in the continent. The Bosco Verticale, also known as the Vertical Forest, is an architectural marvel located in Milan, Italy. Designed by Italian architect Stefano Boeri, this innovative residential complex has redefined the concept of urban greenery and sustainable living.

The Vertical Forest comprises two towers, soaring above the Milanese skyline, adorned with a breathtaking array of trees and plants. The idea behind this visionary project was to integrate nature into urban environments, bringing greenery and biodiversity back to the city.

One of the key objectives of the Bosco Verticale is to combat air pollution and reduce the carbon footprint. The towers host more than 900 trees and over 20,000 shrubs and plants, creating a thriving vertical forest that acts as a natural air purifier. The plants absorb carbon dioxide, produce oxygen, and filter pollutants, contributing to cleaner and healthier air in the city.

The selection of plant species was meticulously done to ensure biodiversity and ecological balance. The variety of trees and plants creates a microcosm of natural habitats, attracting birds, insects, and other wildlife. 

This unique urban ecosystem fosters a sense of harmony between humans and nature, promoting a sustainable and balanced coexistence.

The Bosco Verticale stands as a symbol of sustainable architecture and a testament to the harmonious coexistence of humans and nature. It has transformed the Milanese skyline, offering a glimpse into a greener and more sustainable future for urban living. 

The Vertical Forest is not just a building; it is a living testament to the power of architecture to shape a more sustainable and environmentally conscious world.
