Superadobe Technology

Developed by Architect Nader Khalili, Superadobe is a form of earth bag construction using sandbag and barbed wire technology [2]. In the Philippines, Beau Baconguis adopted the Superadobe technology and designed and constructed the Kapusod Earth Dome and the Climate Resiliency Field School. Kapusod Earth Dome is a part of an ecological resort serving as accommodation in Batangas. Meanwhile, the Climate Resiliency Field School is a farmer training centre run by the Municipal Agriculture office of Gerona and its NGO partner, Rice Watch and Action Network. [3]

Climate Adaptation Effectiveness

Superadobe considered as climate-responsive architecture can be cyclone resistant [3]. Dome and arched structures built from soil are claimed to perform better in countries prone to typhoons or strong winds [1]. Likewise, passive cooling systems or natural ventilation is an advantage for superadobe earth domes [3]. The Superadobe structures built in the Philippines used elastomeric paint as a water-proofing material for roofs and walls. To ensure that buildings are flood-resistant, these were built on porous ground and gravel bags for the foundation were utilized. Drain canals were also dug around the structures. [1]. Extreme precipitation poses some issues for Superadobe structures (e.g., water infiltration), and would require regular maintenance to ensure structural integrity [3]. This solution might be more suitable in areas that don't experience high precipitation rates.

Evaluations

Economic / Financial Effectiveness
High

Superadobe is a low-cost building technology that uses locally available materials. There is minimal need for industrial background and use of machines, low shipping costs, and low energy input. [2]

Technical Feasibility
High

Beau Baconguis learned about Superadobe through an apprenticeship at CalEarth [1]. However, anyone can learn this building technology [2]. Since Superadobe earth domes are susceptible to extreme rainfall, continuous maintenance and some troubleshooting might be needed. Knowledge on proper plastering and prevention of water infiltration is needed [3].

Social Acceptability
Low

This solution is yet to be replicated in other places.

Environmental Impact
High (+)

Superadobe makes use of natural, reversible, and recyclable building materials causing no harm to health and environment [2].

Mitigation co-benefit

Emissions for the earthbag building method is very low due to minimal use of cement, concrete, steel and timber. During construction, intensive transport and use of machinery are not required. Additionally, natural ventilation for the building reduces energy use. [3]
