Green Building in Haiti
Amanda Johnson, Jeff Price, Rose Haft, Hassan Husain
Purpose StatementThe village of Cange, Haiti currently houses around 12,000 residents and is expected to grow rapidly in the near future partially due to the presence of the Zanmi Lasante hospital but also more recently due to internally displaced persons from the earthquake disaster near the capital city, Port-au-Prince. Cange needs sustainable building design to accommodate this growth. The goal of the project is to provide current and incoming residents with an actual home design to be constructed using predominantly locally available materials at a low cost to the owners and surrounding environment.
Green Building for Refugees • New Cange Residents
o Displaced Haitian citizenso Families of Zanmi Lasante patients
• Eastern Haitio Steep slopeso Extensive rainy seasonso Deforestation
• Needso Cheap materialso Easy to buildo No/low wood requirements
Built at Pwoje Espwa in Southern Haiti
