<br>
Although on the EBNet <st1:country-region w:st="on"><st1:place w:st="on">Haiti</st1:place></st1:country-region>
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 <st1:place
w:st="on"><st1:City w:st="on">Leogane</st1:City>, <st1:country-region w:st="on">Haiti</st1:country-region></st1:place>
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 <st1:country-region
w:st="on"><st1:place w:st="on">Haiti</st1:place></st1:country-region> (and
other places in the world!), there of course is much more to consider about
this building . . .<br>
