May 24, 2010Portland, Oregon Dear Reviewer, The attached drawings have been prepared by volunteers with Architects Without Borders – Oregon, with input from structural engineers from KPFF. Our intent is that these simple designs can aid the people of Haiti as they rebuild permanent, earthquake- and hurricane-resistant homes. The designs rely on the construction techniques outlined in the Confined Masonry Handbook (the original of this document was authored by Marcial Blondet; our volunteers have worked along Haiti ReWired to adapt this booklet to Haiti). These drawings are in draft form. We would like you to review them and provide insight based on your own expertise, be it that of a designer, a building professional or a person with a deep interest in Haiti. We will incorporate comments and issue final drawings as part of the Confined Masonry Tool, to be distributed through Haiti ReWired. Thank you for your assistance. Please forward comments, either as text or mark-ups, to [email protected] by June 11. Sincerely, Abby DaceyArchitects Without Borders – Oregon

Creole House - 1 Story

General Notes

Kitchen and bathrooms not included on floor plans and are assumed as separate buildings from the main housing building.

All dimensions are in centimeters.

Maximum block wall height to be 3 meters.

General Electrical plan indicates surface mounted outlets, switches, and light fixtures.

Creole House General Notes

All exterior and interior walls to be 2 rows of 15cm wide concrete blocks with 30cmx30cm square concrete columns unless otherwise noted.

For Phase 2 and Phase 3 floor plans, preliminary engineering calculations indicate a two-story house would require 3-wythe construction at ground level.

Refer to exterior perspective images for decorative railing locations.

For two story option of Phase 2 and Phase 3 floor plans, add cantilevered slab for stair landing at floor with two 15cmx15cm concrete columns below for support of landing and stairs.

For two story option of Phase 2 and Phase 3 floor plans, add additional column and double wall inside Main Room. See plans for location and dimensions.

Windows are indicated as vented concrete blocks.

Wood window shutters on exterior of house.

Exterior shade awnings to be either cantilevered slabs if constructing flat roof or second story or option of removable shading device surface mounted to wall. See perspective views of locations.

Single wood doors typical.

The following concepts are an outline for an appendix that will accompany the Confined Masonry Tool. The insights have been gleaned from The Barefoot Architect, Building Without Borders and our own experience. We will appreciate any comments based on your first-hand experience, as well as offers from volunteers willing to help develop these ideas.

Siting

1. Preserve trees for shade and to prevent erosion. Avoid compacting soil around tree roots.2. Site buildings for exposure to calm breezes and protection from hurricanes3. If on a sloped site build on stable ground at the center of the hill, not the exposed top or flood and mudslide prone bottom4. Site buildings to catch breezes and direct flow through the house5. Put bedrooms on the eastern end of house to reduce overheating in late afternoon6. Site kitchens and toilets down wind

Windows and ventilation

7. Windows should be protected from sun by either resilient, fixed sunshades or lightweight awnings to be detached or retracted in hurricane season. Trellises for climbing vines could be a compromise.8. Ventilating openings should be placed opposite each other across the house oriented to catch breezes. Ideally the larger of the openings should be on the down wind side. Openings should be both low (but above the splash line) and high in the wall (assuming the roof is not vented) to promote stack effect cooling when cross breezes are not available. Depending on the design of the roof, the upper openings could be at the gable ends or vented hip ends9. Light colors of paint around the window frame and the building interior will better reflect and diffuse light.

Building Shell – roof and walls

10. The roof and walls should be painted in light colors to reduce solar absorption11. South and west facing walls should be shaded by roof overhangs, assuming that the overhangs are secure against hurricane winds. Otherwise trellises, climbing vines, awnings, trees, etc. can be used

Sustainable Design Concepts



Sustainable Design Concepts

12. A radiant barrier of a shiny material on the underside of roofs can reduce unwanted heat gain to the interior.13. Roofs with a steeper pitch will drain water better, provide more room for heat to rise away from occupants, and enhance the stack effect if vented high in the gable ends. It may be noted however that they present a taller profile to hurricane winds. 14. Ideally walls should be protected from moisture by overhangs, rain screens or reinforced double wythe masonry with a 5 cm cavity

Food and water

15. Rain water can be collected from clean roofs, filtered and/or purified and used. Roofs painted white (with a nontoxic paint) will more readily show if they are clean or not.16. Water for cooking can be preheated in a clean container painted black, thereby saving some cooking fuel. If pipe or clean food grade tubing is available it can be used as the heating coil. If placed lower than the storage tank a natural thermosiphon will circulate the water from coil to tank.17. Sturdy solar cookers should be built for kitchens in a spot with good solar exposure. This will reduce deforestation from the ongoing need for cooking charcoal.
