Kay 2.0 is a grassroots effort to develop Haiti next generation sustainable modular housing urban template designed for an extreme environment. Higher hurricane frequency and seismic requirements require new approaches and adapted construction methods. Kay2.0 integrates these structural requirements with vernacular spatial syntax.
Two models are in developement
Urban development of dense neighborhoods with shared green space with decentralized services,rain catchment strategies, wind/solar energy production and strong emphasis on shared green space with obligatory landscaping with native fruit trees.
Country side developments cluster around centers of excellence (schools, community buildings, local hospitals, farm coops)with a strong empahsis on reforestation and agronomy.
In each case the idea is to promote community developement and cultural dimensions with vernacular elements.
The goal is to create the NEW Haitian traditions: of resistant building, reforestation, renewable energy.
This project is to provide a truly authentic design that is feasible and realizable in Haiti. It is also design for an extreme environment, subject to hurricanes and seismic activity and economic hardship. The main features are re-enforced construction packaged as a set of prescriptive specifications familiar to Haitian masons and contractors.
Each home is a community building block based on Economy Ecology: rain capture, renewable energy, seismic and hurricane resistance integrated simplicity. housing adapted to local materials, traditions and fabrication techniques. Reforestation with fruit trees are part of obligatory landscaping for greater autonomy.

Kay 2.0 est un effort populaires pour développer en Haïti la prochaine génération de construction durable modulaire: un modèle urbain conçu pour un environnement extrême. Fréquence d'ouragan élevé et exigences sismiques exigent de nouvelles approches et adapter les méthodes de construction. Kay2.0 intègre ces exigences structurelles avec syntaxe spatiale locale.
Deux modèles sont en développement:
Le modele urbain pour quartiers denses avec espace vert partagé et les services décentralisés, stratégies de bassins de pluie, production d'énergie éolienne/solaire et l'accent fort sur l'espace vert partagé avec d'aménagement paysager obligatoire d'arbres fruitiers indigenes.
Le modèle rurale construit autour de centres d'excellence (écoles, bâtiments de Communauté, hôpitaux locaux, ferme coops) avec un emphase avancé sur le de reboisement et l'agronomie.
Dans chaque cas, l'idée est de promouvoir le développement communautaire et les dimensions culturelles avec des éléments vernaculaire.
L'objectif est de créer les nouvelles traditions haïtiennes : bâtiment résistant, reboisement, énergie renouvelable.
Ce projet est de fournir une conception véritablement authentique qui est réalisables en Haïti. Il est également concu pour un environnement extrême: activités sismique, des ouragans et des difficultés économiques. Les principales caractéristiques sont une construction renforcés emballée sous la forme d'un ensemble de spécifications prescritives en kreyol familiers aux maçons haïtiennes et entrepreneurs.
Chaque maison est un bloc de construction communautaire basé sur l'économie écologique : acquisition de pluie, énergie renouvelable, résistance au seisme et ouragan. Logements intégrés et simples adaptés aux matériaux locaux, les traditions et les techniques de fabrication. Reboisement avec arbres fruitiers font partie de l'aménagement paysager obligatoire pour une plus grande autonomie.

4.6m2 per person therefore space for 10 maximum
223/10=22.3liters per day insufficient for daily use but an improvement to Haiti average water use stats OF 15LITERS PER DAY PER PERSON (http://www.data360.org/dsg.aspx?Data_Set_Group_Id=757)
Ideally there should be approx. 100 liters per person better than or equal to China present use.
Rain capture must be extended with communal cisterns or wells.
load balanced by connecting neighboring rain cisterns together a their tops? or bottoms?
if at bottom any over user draws water from neighbor---any over flow fills neighbors AND SHARED CISTERN
if at top over user never draws from neighbors--any over flow fills neighbors AND SHARED CISTERN
-good except for visible pipe running from roof eave across to neighbors roof eave.

The use of bamboo has been suggested by many as a quick and efficient means to stabilize degraded soil AND provide a rapidly renewable construction material. Unfortunately, bamboo is not yet widespread in Haiti but can be imported from Ecuador, Columbia, Mexico, Brazil and other nearby countries. The Kay2.0 project classifies the use of this material as BETA because it is not yet familiar to builders in Haiti. For the longterm however, it is a promising material.
As alternative to steel or scarce wood, bamboo is an excellent lightweight material to build roof trusses, and even reinforcements. It is a rapidly renewable resource that grows on degraded land and provides soil retention and stabilization with its root system etc....etc...

I heard on SignalFM concern over the growing season approaching then it occured to me: CAN USE PLANES TO DROP SEEDS DIRECTLY ONTO PREPARED URBAN VACANT GREEN SPACES?
Growing season will begin soon in Haiti: for long term supply AGRICULTURE: USE PLANES TO DISTRIBUTE FOOD SEEDS into ARABLE LAND IN AND AROUND PORT AU PRINCE.
Either directly or packaged so that Haitians can begin agricultural activities for upcoming growing season.
Agronomy is a corner stone of autonomy for any country.

Earthbag construction can be alternative to wood frame or masonry construction:
material ,sand, is readily available and INEXPENSIVE. Only the bags and some accessories need to be shipped. However codes, traditions and presently the Shelter Haiti 2010 protocols do not allow earthbag construction for its procurement policies. That may change.
more info on earthbag construction resource see links below: http://earthbagbuilding.wordpress.com/
http://earthbagbuilding.com/index.htm
SOME CALCULATIONS:(based on FAQ page http://www.earthbagbuilding.com/faqs/fillingandlaying.htm#number)
A 32x20 10foot high building would require approx. 1560 #50 Polypropylene bags
@190$/thousand bag-------->296.4$
accessories: rebar, barb wire, ties, portland cement parging etc...
Walls can be built at 4sqft/hour/person therefore the Kay2.0 walls can be built in 22hours by a 12 person team.
We should all collaborate. We have a similar project at http://openarchitecturenetwork.org/projects/haitihousing
We also have a website that showcases the project and is serving as a place for discussion and review. Please join!

Housing built with shipping containers have a lot of potential if done correctly and economically. Haiti has the advantage of inexpensive labor so the economics are better than the overprice pre-fabs sold in North America. So if containers are properly finished and ventilated to resist heat buildup and combined to give more spacious accommodation then it is viable. The main advantage over conventional built-in place construction, is the quality control and speed of installation. No civil or structural engineer to analyze custom design for each site. Instead an engineer only needs to design and validate the anchors, seismic and hurricane resistance rating ONCE and , critical modifications are done in a factory and as long as the installation is done correctly, the housing is safe. Masonry re-enforcements are difficult to supervise or verify without an engineer supervising on site during construction.
I have done some container designs but until proper cranes and trucking is available in Haiti, I would be hesitant to call it the silver bullet of Haiti requirement to house 1million displaced persons.
LETS DO THE MATH: ONE FULL SIZE CONTAINER = APPROX.424SQFT
UN STANDARDS REQUIRES AT LEAST 50sqft per person for sleeping quarters ONLY
In theory one containers can house 8 persons maximum in practice it would 6 for sleeping quarters only. For a kitchen counter, bathroom and proper living space the number is much less. A more realistic number is 4 persons per container with bunkbeds and shared facilities.
Therefore to house 1millions persons would require at least 170,000 containers!
One truck must be used to transport ONE container only. IT CAN BE DONE ..we have car plants that crank more cars per month, and with proper logistics and planning convoys of trucks could build up villages overnight. BUT remember each container can transport construction materials and supplies. COntainers housing can (may well) be part of the mix of housing types n Haiti.
BUT Steel building kits Powerbilt will expedite to #Haiti Model sizes range from 20 to 80 feet width -unlimited lengths http://bit.ly/cul25t.
It must be remembered that their are NO local materials(other than dirt. and sans ramming equipment or vast amounts of stucco to cover earthbags, these methods, I believe, will prove prohibitive) to build Sustainable & Survivable housing. I am not sure what "4 building methods" you are evaluating, but surely Composite Panels is one that should be on your list. The materials may not be homemade, but the product certainly can be. ALL materials used in future Haiti Housing will have to be imported, and that includes bamboo. Woven reeds can make great roofing and siding, but not supporting elements for structures that must have a PROVEN record of having survived, intact, catastrophic earth, wind, water and fire events.(it is what the children who survived the January quake draw every day) Would love to meet with you to share fifty years of experience at low-cost safe-housing.

Hello, I see on your website you say minimum bedroom size is 50 sf per person. I looked at a project on Highway Four (LOve a Child) wherein all the houses have one 8'x8' bedroom. Are they building unpermitted housing?
