1. Green Building in Haiti
Amanda Johnson, Jeff Price,
Rose Haft, Hassan Husain
2. Purpose Statement
The 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.
3. Green Building for Refugees
• New Cange Residents
o Displaced Haitian citizens
o Families of Zanmi Lasante patients
• Eastern Haiti
o Steep slopes
o Extensive rainy seasons
o Deforestation
• Needs
o Cheap materials
o Easy to build
o No/low wood requirements
7. For the Next Set of Slides
• We can delete this but for
• The next few slides we need to cover the

o Climate considerations
o Applications
o Scale
o Assumptions
o Limitations
o Explain Deliverables

Hinweis der Redaktion
I'd like to talk about the basic technology of earthbags here, and why they're ideal for our purposes -Amanda
This would just be talking about -low technical needs (tools) -local labor force (easy to learn) -soil vs wood or concrete (cheap and no deforestation)
Hey guys - Are the trees, water filters, etc. considered materials? Do we need to talk about where we're getting those from?

Hey guys – we need to add these costs into everything too. I’ll do some quick calculations if I haven’t heard from you! - Rose
