==Engineering Verification==
Hello,
We are looking for consulting assistance on structural engineering of walls for a single family house that we are designing. Instead of using standard framing, we are using modular panels to allow for modular construction. We are a nonprofit appropriate technology organization - you can see my TED Talk on the Global Village Construction Set for more about what we do -https://www.ted.com/talks/marcin_jakubowski_open_sourced_blueprints_for_civilization.  We are interested in using our construction methods to make affordable housing widely accessible to the owner-builder. The types of questions that we have revolve around the structural integrity of modular house panels.
We would like to hire you for consulting time, would this be possible? For example, we would like to ask you if you can verify our structural engineering concept for the walls of a single-story residential construction building. The house is on slab on grade, and we are building using 4'x9' wall panels. These are 2x6 lumber framed panels with a 24" on center stud. The panels sit on a sill plate. Please see the concept document attached - https://docs.google.com/presentation/d/17MiaqQ-yA0U_kpegCGK86HNgPwA1lqh-jJdX-2oyNEs/edit#slide=id.g94d53d4eca_0_248. We are planning to begin the build as soon as we have the complete design. Our question is - is the panel-wall design structurally sound for shear forces? We are using a top plate for shear stabilization of adjacent panels. Adjacent panels are fastened together using nails or screws. We have this and some other structural details to resolve.
Please let us know if we can hire you for consulting on this.
Thanks,
Marcin

Hi ________,


We are taking the Seed Eco-Home to product release next year. We are doing a major campaign with a goal of getting 2000 built over 2 years. The promise is a 1000 sf home for $50k that you can build with a friend in one week. That's a significant offer, and we think we can do it. The trick is: people build and stash modules, then have a week-long build with, at minimum, one other person.  
See [[Seed Home 2 Design Log]].


There is one outstanding issue that we are negotiating: the joint between panels. It is critical - as it's what allows all the walls to be done, from prepared panels - in about 4 hours for a 1000 sf house. We used tongue-and groove exterior panels in our last build, and build the walls in less than a day, including building panels. You can see more pictures of the stellar product after 4 years at https://docs.google.com/presentation/d/1zKOMjNU4qP_xndJ1r5LLmJLNujjfy8LPEyflKgELZWM/edit#slide=id.g5c3be0ce2d_1_28
=Exterior Stain=
Seed Eco-Homne mix is:
#(3) parts Cabot Gold Sun-Drenched Oak Oil-Base Exterior Wood Stain [https://www.menards.com/main/paint/exterior-paint-stain/exterior-wood-stains/transparent-waterproofing-sealers/cabot-reg-gold-satin-oil-base-exterior-wood-stain/140-0003470-007/p-4364363663390696.htm]
#(1) part Cabot Australian Timber Oil Jarrah Brown Exterior Wood Stain [https://www.menards.com/main/paint/exterior-paint-stain/exterior-wood-stains/transparent-waterproofing-sealers/cabot-reg-australian-timber-oil-reg-exterior-wood-stain-1-gal/5533004/p-4364363663390706.htm]
#(3) parts mineral spirits [https://www.menards.com/main/paint/solvents-cleaners-removers/thinners-solvents/sunnyside-reg-mineral-spirits-premium-paint-thinner/80332/paint/solvents-cleaners-removers/thinners-solvents/sunnyside-reg-mineral-spirits-premium-paint-thinner/803g1/p-1444444213131.htm]


That is 1400 sf. We're planning on 1000 sf and flat roof for the product release.
Then we applied a different number of coats on each row of siding panels to get a sort of gradient: 3 coats on the bottom row, 2 coats on the top row, and 1 coat on the top row.
 
For the product release, we'll use plain exterior treated plywood panels to simplify the joint. Please take a look at the doc and comment on - whether the 2 routes proposed can be negotiated through codes and existing inspection schedules. Which one would you suggest? Do you have another solution? Would love your insight, and also your help in the product release. We're planning  a large scale collaborative design where we publish an open enterprise model. We plan on training 100 entrepreneurs to do the builds, and a number of one week on-site training for owner-builders where we build an entire house in each event. So essentially, really taking it to prime time - it's all working and we want to solve housing as promised.
 
Thanks,
Marcin

For the addition I want to match the bottom row, but instead of doing 3 coats of the formula above, I'm planning on doing 1 coat of:
Marcin,

This is exciting... I can imagine this system developed with different materials for application in different contexts.
#(1) part Cabot Australian Timber Oil Jarrah Brown Exterior Wood Stain [https://www.menards.com/main/paint/exterior-paint-stain/exterior-wood-stains/transparent-waterproofing-sealers/cabot-reg-australian-timber-oil-reg-exterior-wood-stain-1-gal/5533004/p-4364363663390706.htm]
#(1) part mineral spirits


On the wall module interface, in the second image it should show exterior sheathing, then weather barrier, then siding.  The weather barrier goes outside of the sheathing.  It could be that the module does not include the weather barrier and siding- this would be a more historic approach.  Similar to stress skin panels that are plywood and insulation- no studs thus decreased temperature bridge issues. See attached images.  The blk and wh from one of Harry's first projects.
I think that for future houses we should use this second formula and do only 1 coat. But I can't know for sure until I see what it will look like once the wood panels darken.
The first solution could be useful for improved structure.  How are the panels and framing connected?  Would be interesting if these 1000sqft house modules could be joined in a larger structure.
The second likely would not work with building codes but there is a newer system that uses a ceramic coating on the plywood sheathing as the weather barrier and a tape at the joints.  I am sure they had to go through all kinds of testing to get this to pass codes.https://www.huberwood.com/zip-system


What are the goals of the prefabrication part other than for a handful of people to be able to raise it in a week?
This is for color only. We'll need an oil-based sealant on top.


==Dan==
I'm going to develop some alternative palettes for other people's houses, which will include paint (in satin sheen). Exterior paint doesn't need a sealant. But I don't know how many coats we'll need nor if we need a separate primer. We'll have to test.
