[Greenbuilding] energy efficient pop up house

[John Salmen]

Nice building. Looks nicely thought out. Most every building code has a ½ hr
minimum firewall requirement for interior finishes so it would likely have
to have those facings. I think some European standards look at whole
building performance in fires and its possible that eps might qualify as it
doesn’t do too badly in fires doesn’t do too badly in fires (I can hear the
gloves falling off). 

 

Typically the smoke from burning wood components will kill you long before
the foam ignites. Foam is 98% air but low mass so can produce less heat in a
fire which is important. Lots of studies on it.

Further to that note about the energy efficient pop up house, a friend who
read the piece better than did I, pointed out:

There are some good ideas here, but at least one really bad one: the whole
interior is foam plastic, not legal as an exposed finish because it burns
like crazy and produces extremely toxic smoke (in spite of being pumped full
of (probably) carcinogenic flame retardants.) Also, calling polystyrene
recyclable is fudging at best.

I expect Rob Tom would agree fully with an 'echhh' to boot.  The idea
however, of easily putting together a house lego-like is most appealing.
SIPs come close to this idea.  Sacie
