Although on the EBNet Haiti team (in addition to the BWB SB Haiti team), I'll jump into the GSBN forum with a couple thoughts on the plaster and the security issue.<BR>
<BR>
The security concern will be greater in some locations than others. Generally, the more urban the greater the concern. It seems obvious that both in perception and as a physical obstacle, mesh reinforced cement plaster would be the most secure plaster, and I’ll say probably secure enough. (Notwithstanding Derek’s proposed method of breaking and entering, that still takes time, effort, makes noise, etc, and thus is a deterrent). In some cases clay, or lime plaster may not be enough, in other cases it will. Installing a second plaster on the inside face of the bamboo framing would provide additional security (real and perceived). <BR>
<BR>
For the Home Expo building I suggest installing a cement plaster (with up to 50% lime if you can get your hands on it) on half the building, and a clay plaster with a durable finish on the other half. With and without a second plaster on the interior. Let people see how they both feel, look, and sound, and allow them to decide which would work for their circumstance.<BR>
<BR>
Cordaid, a Dutch organization, built a prototype wood-framed house in Leogane, Haiti with no less than 7 enclosure-finish systems. (I can send photos, if you haven't seen it already.) I think it goes too far to the point of being chaotic/confusing. But a couple variations in one prototype building seems valid to me. Looking at opposite corners you might only see one finish at a time.<BR>
<BR>
In terms of security, doors and windows (shutters?) will probably be a greater point of vulnerability than the wall enclosure system. I would show how that can be addressed on at least one opening. <BR>
<BR>
Also, although security can be a serious issue in parts of Haiti (and other places in the world!), there of course is much more to consider about this building . . .<BR>
