the wall section provided an opportunity for the architect, miche booz, and the wall fabricator, bruce jones, to discuss the construction and make refinements that would result in a more efficient build.
the wall section also serves as a check that the wall will be constructed to passive house derived requirements and that the windows will be installed to passive house derived requirements.
this is so much better than starting to build the wall for the house and then finding an oops. my thanks to bruce jones.
in back of the wall section is the house i am living in now. it will be torn down subsequent to the new build. very early in the project, the architect, miche booz, and the passive house consultant, michael hindle, and i discussed the environmental and cost impacts of renovating the existing home. we decided that it was best to go with a new home even from environmental considerations alone.
fabricating the wall section
to be sure the details were right, bruce jones fabricated a wall section. shown to the left is the wall section under construction at bruce’s factory

spill response plan and spill kit
LEED advises that a spill response plan is worthwhile for environmental protection. here’s a picture of our spill response plan and spill kit.

the footings are not thermally insulated from the ground
in compensation the slab, which will form the home’s floor, will be insulated from the footings
feed-throughs for electrical cables
the house will not have wall penetrations for electrical cables and will have only one penetration for plumbing
the roof will not be penetrated
the penetrations go through the footings and will then penetrate the slab. this should make for a more reliably air tight seal than wall penetrations. no roof penetrations will reduce the possibility of leaks
cleanly cut tree roots
during the dig for the trenches, a few of the cherry tree roots were torn. to make it easier to for the roots to heal, i made a clean cut where the roots were damaged
trench and rebar
this dug out area will be filled with concrete, which will provide the house’s foundation
silt fencing to prevent soil erosion. the bottom of the fencing is packed into a trench to keep sediment from getting through
disturbed earth under new grass
one of the first disturbances to the property was the digging of three holes for perc tests. this satisfied howard county that there was sufficient permeable soil for three septic fields should the existing field play out. this left unprotected soil on the surface.
to keep the soil in place, i used recommendations from my landscapers and the epa’s developing your stormwater pollution prevention guide. i seeded the areas with annual rye grass.
