Protype B: Load Bearing Wall System
Reinforced concrete load bearing wall systems have grown in popularity throughout the developing world as a strategy to provide the strength of monolithic, cast-in-place concrete construction at an affordable price for large development projects. This structural system provides the architect with flexilibity in the initial layout and is a quick and efficient means of construction: allowing a the home to be completely formed and cast in as little as 1 day. The Expo showcases this concept, employing the pattented forming system developed by Western Forms International, as a two room, 288 sq. ft. starter home with a covered porch and both concrete and wood framed metal roof options.
Prototype A: Frame (MRF) and Panel System
In order to overcome the barriers and constraints unique to Haiti, E2E developed a new housing model that decouples the walls from the primary load path of the home. The introduction of a reinforced concrete moment resisting frame (MRF) provides the necessary strength against earthquakes at an affordable price, while employing prefabrication and standardization to deliver quality control. More importantly, the use of the frame allows flexibliity in cladding and partitioning options so that the home can be expanded, adapted and customized with time...critical needs given the financial realities of displaced families. The Expo showcases this concept as a two room, 288 sq. ft. starter home with covered porch and clad with lightweight, precast concrete panels that can be expanded in size over time as a family accumulated more savings.
