Application of Earth and Timber as Primary Structural Materials by Cameron Bailey & Aimable Mukire

Описание: Technical Talk 5 titled “Rwanda Institute of Conservation Agriculture (RICA): Application of Earth and Timber as Primary Structural Materials” by Cameron Bailey and Aimable Mukire

Globally, the built environment consumes half of all materials, contributes almost 40% of global greenhouse gases, and produces 30% of waste. While Africa has historically not contributed significantly to these negative environmental impacts, its projected population doubling by 2050 will make it a major player in construction. Fortunately, Africa is home to innovative designers who are actively addressing this issue. MASS has been deeply involved on the continent for nearly 15 years, focusing on healthcare, affordable housing, community resilience, and conservation. Through various projects, MASS has demonstrated how thoughtful design can minimize disruption to ecosystems by reconsidering material choices and usage. Two notable projects exemplify this approach.

RICA, the Rwanda Institute for Conservation Agriculture, integrates biogenic and low-impact materials while using the construction process for training and job creation in regenerative practices. These structures, located in a seismic zone, utilize stone foundations, compressed earth brick walls, and wood roofs to reduce embodied carbon by 60%. Notably, 90% of the project's budget supported the local workforce and material supply chains within 500 miles of the site, fostering community prosperity.

Cameron Bailey:
Cam is MASS Design Group’s Director of Engineering specializing in design using natural materials, particularly timber and earth. Cam also leads MASS’s Conservation & Communities initiative, focusing on regenerative infrastructure that bridges climate resilience, ecological preservation, and community-led development.

Aimable Mukire:

Aimable is a Senior Structural Engineer at MASS with a background in natural material research and development. He has extensive experience in researching and testing locally sourced materials, particularly earth-based construction. He also leads integration of carbon reduction strategies throughout the design process.
