Marcin and I built the spool assembly for the Trencher. It is too tall to get out of the garage in one piece so we had to make it removable. We finished hooking up the Hydraulics to the trencher and took it outside to try it out. It was front heavy so the tractor lost all traction on the rear tires. The trencher also didn't quite have enough power to dig, so we put another power cube on the back for additional power and counterbalancing.

started fabrication of the Wire feeder. I need some more 1 1/2" bar stock to complete the task, but Sweiger was closed, so I may have to come up with something else.

Fabricated the guard and added some additional side metal for added protection.

=Wednesday November 27th=

Removed small cylinders from tractor and begun mounting and fabricating larger cylinders. This requires modifying the mounting brackets and creating a custom welded bracket.

[[Image:CylinderUpgrade.jpg|500px]]

Additional lighting in the workshop would be helpful in productivity especially after 5:00 in the winter.

Larger cylinders require moving of both front and rear brackets.

[[Image:CyliderBrackets.jpg|500px]]

Opened spool of PEX piping to see if it unreels. Spool did not unreel. This could be due to the cold temperature, but it seems that we won't need to add the chair on the front of the Trencher unit.

Additional lighting in the workshop would be helpful in productivity especially after 5:00 in the winter.

Larger cylinders require moving of both front and rear brackets.

Further comments:
*make the chute guard more wide so it can withstand larger forces. Make it 3/8"x4" or 3/8"x6" metal.
*Make the arms supported by a threaded rod coming off a vertical attachment - to support arms by tension
*Support the digger with 24" of span - can weld a vertical on the mount tubes

'''Narrow Guard'''

'''Get rid of Bobcat and leave a rectangular structure – assume that we hang with a long flat bar, foggedabout bobcat qa'''

'''Replace the spool bar with a 4x4'''

'''Use a single 4x4 for holding the spool'''

Guard narrowed to 8"
Rectangular mount of tube - 12" h, as we discussed on the phone. I see what you mean about not much support. And regarding the welding of all pieces - that's how it looked to me in the sketches.
Don't think spool bar can be 4x4 - need to be able to put a spool with a smaller hole, like for electric cable.

[[Image:Trencher_guard.png|500px]][[Image:Wire-spool-black-1000.jpg|300px]]

'''Wheel – 5' diameter – need 3.5” hole in center, and do the standard 8 bolt truck wheel pattern but use 1” bolt holes – really do 1-1/8 for the hub mounting'''
Yes.

[[Image:Trencher-8hub.png|600px]]

'''For the teeth, do 3/4”+1/16”'''
Yes. holes are 13/16"

'''Sandwich 2 sheets of 1/4” flats around the chute; chute needs to be lowerable'''

[[Image:Trencher_chute.png|400px]][[Image:Trencher_chute_dtl.png|400px]]

Trencher chute gets pinned between two short 4x4. Notch plate on side of chute to receive pin.

'''Make plane of the quick attach wheel about 10” away from the cutting wheel – to allow sleeve a'''

Not sure I have that one exactly right.

[[Image:Trencher_10in.png|600px]]

'''End the arms with the plate of the qa wheel'''

Holes on motor mount plate do not line up with holes on support arms. We can move these holes wherever we want, right?

'''The reinforcements neeed to be pointing up to achieve 3' dig depth'''

I changed the support arms to the top... don't think this is what you had in mind.

Thoughts:
Add smooth flange at pipe ends to avoid damaging wire or flex pipe fed through it?
Radius shown on chute is probably impossible to achieve through bending. I don't think we want the chute to extend further under the tractor, though. Maybe use long-sweep plumbing fittings?

=Mon Nov 11, 2013=
Words from the founder: Along the lines of Superfast Basic Build -

I think the way forward is to start with absolute basic shell that we can do in one day. I propose that we do a version on a treated lumber footer or stabilized brick footer - for a shed or similar - and see how we can fork from there to additional features - while allowing for a ONE DAY BUILD INCLUDING FOUNDATION + GRAVEL.

Can you draw up an hourly equivalent corresponding to http://opensourceecology.org/wiki/File:MH_Workshop_Schedule_Graphic_Final.jpg but for the 1 day build? I suggest that 7 AM gravel delivery is the start point.

Eventually, add a realtime limestone burn to generate our own mortar, like Frank Lloyd Wright (FLW). Eventually, strawboard manufactured in realtime - which we should have a prototype of by January if Chris sticks to his schedule of tech dev - which so far is on schedule with the trencher build.

What do you think? I think that could be radical.

I could see things like water heater, sink, etc, being mounted right on the brick wall - where we modularize via install onto "quick mounting plates" paralleling, for example, quick mounting plates for tractor hydraulic valves - where 1 bolt and quick couplers intall an item in 5 minutes - pending a quick mounting interface to the object of interest. What do you think of this?

So: say a water system module: sink on a mounting panel featuring quick connects. Water heater on a panel featuring quick connects. Shower module without drain but with small sump pump draining to a single sink drain. Universal Shit Muncher module for toilet - emptying graywater into the same drain. So 1 drain for entire house. Etc.

I think we can radically improve the speed AND approach a modern home standard at the same time. I just think we have to Think Diffferent. Further, we need to figure out how to end a house without having to do all the trim work as in the last one. That is killing us.

==Microhouse Development for 2014==

Marcin requested development of a One Day Microhouse... a great idea, and I think a better label for it than what we had been referring to as the "Third World Microhouse." They are essentially the same thing. To simplify development, there are two main tracks for evolution of the Microhouse, as displayed in this mock-up graphic. (Images for One Day and LBC Microhouses are just place holders.)

[[Image:Microhouse_Evolution_for_2014_-_Two_Tracks.png|700px]]

I would love to see a graphic like this flushed-out to be part of the Microhouse promotional materials. A question is raised by this: Do we format the graphics for slideshows (i.e. - widescreen) or for print? I think that the digital presentation version is the way to go, unless graphics are intended to be printed as construction documentation.

==Microhouse Commercial Work with Rob==

Rob and I continued work today on the Microhouse commercial to attract both participants and hosts. A two-column script for video and audio was generated for a second pass. The first pass was posted in log a few days ago.

==Continued Work on Trencher with Marcin, Dorkmo==

Email from James, related to work below:

"minor thing, i think it need to be rotating so that the teeth are coming up out of the ground on the side that the cutter is traveling?

its looking great"

(contained the following image)

[[Image:Trencher_direction.png|400px]]

My response:

"I don't know! I've wondered this very thing :)

Like with a circular saw blade, the blade moves opposite the direction of travel so that the tool does not "get away from" the user. What I wonder is, with such a large device, is the idea the same?

Looking at images of industry wheel trenchers, I get the impression that the machine travels in a backwards direction, and it looks to me from the teeth, that the wheel cuts opposite the direction of travel.

Does it look the same to you?

If so, I'll reverse the direction of the guard, the chute, and the spool, and change the direction of the cutting wheel, too.

==Dorkmo Updates + Trencher Tooth==

[[dorkmo Log]] made changes to tooth attachment. I added a plate to the tooth to widen the trench slightly.

[[Image:TrencherDorkmo1+wideteeth_1.png|400px]][[Image:TrencherDorkmo1+wideteeth_2.png|400px]]

To me, this is the most important functional specification- what is the range of trench widths that this design can support and what is the minimum functional width at a depth of three feet? There is a obviously a maximum width, where the teeth can no longer cut through the soil. On the other end, there is a practical minimum width to the trench that I see to be 3". Especially at a three foot depth.

The walls of a trench, even in stable soil are never totally clean - rocks, roots, and loose soil often project from the walls. There is also the constant tendency of the loose soil that has been excavated to fall back into the trench. For these reasons, in incredibly narrow trench -- just the width of the disk and the narrow teeth (2" as currently drawn) is not functional. 3" may work, but I think 4" or 5" would be even better. There is also the need to clean the trench with a trenching spade, and the standard width of a trenching shovel is 4".

[[Image:trench_sketch.jpg|400px]]

A little research into industry standards shows the relationship between width of trench and depth.

[Image:Width_Depth_Table.tiff|800px]]

Following the standards on this table would mean we would want our trencher to have the power to cut a 6" wide trench.

Using teeth 5.5" wide, with the 1/2" offset created by the disk (should this thickness be 1/2" or 3/4"?), gives a 6" wide trench.

[Image:TrencherDorkmo1+wideteeth5.5.png|600px]]

==Trencher Draft==

Based on Marcin's Sketches (http://opensourceecology.org/wiki/Trencher_Concept_Drawings), an initial 3d Sketchup model of the trencher is born:

[[Image:Trencher_Draft_1.png|400px]][[Image:Trencher_Draft_2.png|400px]]

Next step is to add the Bobcat stand quick-connect. Also, need to add another piece to the tooth component to create the desired width for the trench.

[[Media:Trencher_Draft.skp]]

==Meeting with Zach Dwiel==

Sat down with Zach today for an hour to get an update on their CEB project and share our experience with the Microhouse. Fruitful conversation that covered topics of stabilized bricks, methods of wall construction, and especially figuring out ways to insulate CEB walls that don't require incredibly wide foundations (like Zach's). Also discussed ideas for a machine that could mix pulverized soil with small amounts of cement and/or lime to feed the brick press a homogenous mixture for stabilized CEBs.

I'm going to head out to Zach's this weekend to photograph his home and get some details of how the double wall construction worked and lessons learned. I will write this into a blog post that covers both the technical aspects of construction as well as touching on the human interest of a young couple building their own home with OSE's brick press.

==Meeting with Jean-Baptiste==

I had a google hang-out with Jean during which we discussed next steps for the Microhouse infographics. We talked about the following changes to the main Microhouse graphic:

- showing the plaster cutaway so that it looks more like a cutaway and does not stop at the same point as the brick
- showing siding and wood trim on upper modules, cutaway in the same fashion as the plaster
- showing bricks for trombe wall on inside of window modules
- showing the as-built stacking pattern
- showing bricks near the door frame "stacked up" the same way they are displayed by the utility module
- showing utility module penetrations through wall
- showing CEB walls extending above the loft to reflect actual construction

I provided Jean with a copy of the Sketchup model for his reference. We also discussed another infographic sheet that details the passive solar functioning of the building. It will be a combination of a simple sketch I poster earlier on the log (Windows and Door Modules complete) and the section cut through the Sketchup model:

==Reaching Out==
==Connection formed with Molly Reichert at U of M==

Conversations have begun with Molly Reichert, an architecture professor at the University of Minnesota. Their school has a hands-on maker focus that is in alignment with OSE. Sounds very promising. Molly is interested in bringing Marcin, myself, or both of us there to speak, attend a review/critique, and potentially run a workshop. Here is a description of the class she will be teaching in the spring.

"FarmTECH: A course that builds on the Farm Hack movement, Open Source Ecology, and addresses issues surrounding self-sustaining communities and local food systems. This course fits within the emerging field of urban agriculture and DIY tool building practices. Students will research current farming practices through site visits and workshops with local farmers. Coursework will address unmet needs of the industry through designing and building tools. Tools could range from climactic sensors, to farming implements, to food processing equipment."

Molly is also interested in the combination of Wiki House and Microhouse ideas, and she asked for my input on her development of a course for fall '14 based around this idea and incorporated into the Microhouse Competition.

==Initial Responses from Udall Network==
Sent out the Microhouse flyer with an introduction to the Udall network. Received three responses in short order regarding finding a workshop host in the south:

1 --------------------------
Hi Chris,

It's not my area of expertise, but here in Austin Texas seems like a good place to try it. Poke around, and good luck,

Oliver

2---------------------------
I am just moving to Quebec from TX. I know you're looking for a southern host but do you have any openings in the spring or summer to do a workshop in QC? I'd be very interested in hosting one?

Hi Chris,
Sounds like a great workshop. Here are a few ideas off the top of my head.

I'm on the board of the Highlander Research and Education Center located just east of Knoxville, TN with an amazing view of the Smoky Mountains, and if you're interested, then I'd be willing to work with you to try to set up something at Highlander.

==Final Flyer and Schedule Promotionals Created==

Posted to FeF blog entry regarding host search for Southern U.S.A.

=Friday Nov 1, 2013=

The search for the Microhouse client is on. Over the past few days, we have been in-house editing the requirements for the workshop hosts and the nature of the agreement between OSE and the hosts. Several documents reflect worked-through but not-quite-final drafts:

[https://docs.google.com/a/opensourceecology.org/document/d/17Y70TaSTr1NrK0ejHiReIQvGwQc61pO1Cj6CaXDGgq8/edit]

[https://docs.google.com/a/opensourceecology.org/document/d/1H_dVFdPMyZFwfs-S_aXjzJEHqbQZ1e6J8RgWcAwMM8E/edit]

I think the best way for potential hosts to become interested is through some kind of media contact - either an image or a video that they see on the internet, or in the case of an image, possibly in print. I wrote a rough script for Rob to make a rough cut of a commercial, and I made a workshop flyer for distribution on the web, and as part of a grass-roots campaign to get our friends and fans everywhere to print it out and hang it up where they think like-minded people may see it.

==Presentation at Ball State Alumni Symposium 2013==

The presentation today went very well. Had a standing room only crowd of roughly 50 in a small room. Who knows how many there could have been. People kept coming just inside the door and then leaving because there was no room left. By the end of it, there were people standing in the hallway and watching, as well as sitting on the floor.

[[Image:bsu symposium 2013 crowd.jpg|400px]][[Image:BSU symposium crowd 2013.jpeg|400px]]

There were seven or eight students that expressed interest to me after the talk about OSE's work and the Microhouse. They were all looking for opportunities here, though, and it makes me think that developing a special workshop just for design students is a solid plan. It would basically be a very similar workshop build like we have done for the Microhouse, but it would include nightly design charrettes, where the students get engage their drawing and creativity in addition to developing their hands-on skills. I would like to try one of these in Bloomington in the '14 building season on my property to give those students from Ball State that are not able to travel the opportunity. We could also try one at FeF and market it to local and regional architecture schools.

John was there, and I promoted his LA471 class as another opportunity to become involved. He and I did not have much time to talk after the presentation, but I will catch up with him soon. I plan to be doing a small but regular amount of my remote work from here in Muncie, to have access to the resources of the University - the architecture library, the professors, and the students - also the laser cutter and the CNC router. If we need to get more items laser cut, I could do them during my time in Muncie and the only cost would be the material that gets cut and the shipping.

I counted about 7-8 professors - I knew four of them: George Elvin (who is working on the Post-Petroluem book with the Microhouse as a case study - I recommended again that in addition to the Microhouse interview, he talk to you, Marcin, about the rest of the GVCS and how it relates to a post-petroleum future. He was excited by that.) Walter Grondzik (who donated some free engineering consultation on Microhouse 1.0), Andrea Schwartz (a professor of structures and studio), and John Motloch. This is great. I feel that over time, "recruiting" professors is an even better plan than recruiting students, because the professors then become recruiters themselves, hand-picking the types of students we want and encouraging them to work with us. I have heard John talk about playing this role successful for Pliny Fisk. In fact, my mentor, Dan Overbey, was connected to Pliny through John and the LA471 class. This is a reminder of what a boon it is that John is making the master plan the focus of his class.

Overall, great response from the presentation. Look forward to doing more. Having the log here on the wiki and the other documentation like the Sketchup model and the instruction manual is great for presentations because I can show people the documents we used to make this happen. Most of the information has already been captured.

=Thur Oct 24, 2013=
==Long-Term Goal==

The long-term goal for the Microhouse project should be that individuals could create every single component of the home themselves, including the insulation material, the nails and screws, the pipes, and even the glass. Microhouse 1.0 is a proof-of-concept learning model, but the ultimate concept is NOT for people to have to go to the building supply store to buy the products needed. People need access to the knowledge and machines to create building components themselves.

==Thought for Immediate Expansion==

One challenge with such a tiny home is finding space to store stuff - not the multitudes of junk that consumer culture pushes on people, but the necessities, like clothing. Here is a thought for how to add a small closet space to the upstairs of the Microhouse and later fill in underneath it.

[[Image:closet addition.jpg|800px]]

The underneath portion could become a low-tech "ice box" or root cellar. If we shade if from direct sunlight (perhaps with an upstairs deck that could be accessed from loft bedroom), and couple it to the thermal mass of a cistern, I think we could maintain a low enough temperature for it to be functional for food storage.

[[Image:closet addition 2.jpg|800px]]

Also have begun thinking about how we might create village clusters of Microhouses at both Factor e Farm and other locations. Basing this information off of traditional neighborhood development wisdom coupled with passive solar ideas. More ideas on this to come... this is just a brainstorm starting point.

[[Image:village microhouse.jpg|800px]]

==Energy Modeling==
Marcin,

Another project I plan to work on during the cooler months, when we are designing and planning for workshops, is to do energy modeling on the microhouse using sketchup and some other available plug-ins.

My mentor for the Internship Development Program, Daniel Overbey, is an expert in these matters and can give me guidance. This guy is awesome. He worked for Pliny Fisk for a while - here's a brief bio:

Daniel is recognized for his work in the area of environmental design and building systems analysis. Daniel brings a unique research and design background to Browning Day Mullins Dierdorf Architects. Prior to joining the firm in 2008, Daniel worked for a non-profit education, demonstration, and research organization in Austin, Texas, an architectural research lab in Las Vegas, Nevada, and served as an environmental design specialist for an architecture firm in Las Vegas, Nevada. Currently, Daniel provides research, design, and building systems analysis services to various projects. Before earning a Master of Architecture degree from the University of Nevada, Las Vegas in 2007, Daniel earned a Bachelor of Architecture and a Bachelor of Science (Environmental Design) degree from the Ball State University College of Architecture and Planning in 2005.

What it doesn't say is that he publishes articles constantly and is very well connected in the national sustainability movement. He's also the president of the Indiana Chapter of the US Green Building Council. Recently helped move graywater legislation through the state house, too.

Anyway - if we sensor the hell out of the Microhouse and compare the actual data with the energy modeling, we'll get a great sense for how accurate the energy models are. This will help us use the modeling tools on future design/builds, at the same time providing valuable research to the world at-large on how accurate energy modeling is - especially to earthen structures.

==Indirect Solar Heater Doubles as Truth Window==

It is quite common in the natural building world to install "truth windows" - a window that let's one see what the wall inside is actually made of. In our case, the truth window doubles as an indirect solar heater. The sun's rays shine through the double-paned glass, warming the earth blocks. The heat energy slowly moves through the blocks and is released into the interior space.

[[Image:truth window 1.jpg|400px]][[Image:truth window 2.jpg|400px]]

I think these large truth windows turned out beautifully!

==Interior Finish Work Moving Along, Electrical System Tested==

We finished all the utility module connections today.

[[Image:utility module connections.jpg|400px]]

We also tested the majority of the electrical system and began installing the kitchen cabinetry.

[[Image:kitchen color.jpg|400px]][[Image:cabinets.jpg|400px]]

==All Exterior Finish Work Complete==

Today we wrapped up the exterior finish work on the Microhouse, and it's looking sweet.

==Trimmed Out Upper Level==

Today saw the siding get finished and the upper level all trimmed out. Really starting to look finished now!

[[Image:trim from NE.jpg|400px]][[Image:trim from SE.jpg|400px]]

We also finished the interior plaster, set upstairs "kickboard" panels, and made 90% of the utility module stub hookups. We also positioned the instant H20 heater.

=Sat Oct 19, 2013=
==Siding Complete on Two Sides, All Windows In==

We were able to get the siding up on the east and north sides - it is wonderful to see the color next to the earth plaster! It is really going to pop once the bottom, top, corner, and window trim goes on.

[[Image:siding 2 sides.jpg|400px]]

We were also able to get all the windows in. This is always a wonderful moment in home-building... where it really starts to feel like a house.

[[Image:south windows cody painting.jpg|400px]]

We were also able to get quite a bit of interior finish work done, but by dusk it was too dark to get photos of the work. More interior shots coming tomorrow!

==Siding and Windows Going In==

Some of the details are becoming apparent - really starting to come together.

[[Image:west window.jpg|400px]][[Image:siding start.jpg|400px]]

==Microhouse Finish Work Gets Underway==

Arrived mid-day yesterday and immediately got to work with Rob, Cody, and Mark on the Microhouse 1.0 finish work. Mark trimmed the metal roof and added the edge trim in addition to finishing screwing down all the panels.

[[Image:Mh roof.jpg|400px]]

Cody and I added the majority of the interior ceiling panels and installed the upstairs window.

[[Image:upstairs window.jpg|400px]][[Image:ceiling panel installation.jpg|400px]]

We also began the caulking and foaming to tighten up the building envelope. Today we continue with more window installation, adding the exterior siding, and beginning wood trim.

Have any of you guys seen this book?

http://www.amazon.com/Tiny-Homes-Shelter-Lloyd-Kahn/dp/0936070528

A book all about tiny (less than 500 sf) homes, by the well-known builder/author Lloyd Kahn (his first big hit was the highly influential book on DIY housing, Shelter).

Here's a little 2:00 minute video trailer for the book.

http://www.youtube.com/watch?v=u-2fsYypJoo

I mention this because I am going to contact him with the intent of getting the Microhouse in his upcoming book Tiny Homes 2. He and I have some mutual friends in the natural building world, so I think I'll be able to reach him without any difficulty.

==Next Microhouse Iterations Move in Two Directions==

More details to come, but I think the next versions of the Microhouse should move in two different directions - one is the simple, very inexpensive, "third world" version. The other, a more refined, "first world" version. The Dwell magazine, version. Microhouse 1.0 is somewhere in between, but closer to the full-blown first world model.

[[Image:Microhouse 2 directions.jpg|400px]]

==Infographics!!==
I love the beginning of the Utility Module inforgraphic that Jean-Baptiste is working on. It looks fantastic!! Way to go, Jean!

I've got some various graphics in the works myself ;)

[[Image:Poster_w_exploded.jpg|400px]]

Obviously it's a mock-up. The graphic in the middle doesn't match the element logos for the modules, but I think you get the idea. A simple exploded diagram in the middle (on a white background, not gray), with leader lines extending to element logos for the different modules. Next to the modules, we place a photograph of the actual module. Short descriptions could be added, too. Need to finish element logos for all the modules.

Here's another mock-up - the idea here will be more like the periodic table. A simple arrangement of the element logos of the Microhouse.

[[Image:Poster_w_elements.jpg|400px]]

And here's one more... this one is an aesthetically compelling photograph of the construction process showing which modules are used.

[[Image:Interior_Loft_Construction.jpg|400px]]

I think if we took well-composed (artsy, even) shots of construction, we could make a series of explanatory images showing how the modules come together during the construction process.

As I prepare to leave OSE headquarters and the Microhouse build I feel a mix of emotions.

I am elated at our progress and impressed with the quality and quantity of work that we have put out in the past 6 days. Building projects require the convergence of a multitude of inputs, and this one has gone more smoothly than many do. As a professional designer and builder, I am no stranger to solving problems on the fly and dealing with the unknown, but this project has been full-speed ahead from day 1, with no need to bring things to a halt and make a new game plan, the result of a robust design and planning process and many conversations between Marcin and I... and a very accurate and detailed sketchup model!

In addition to my happiness with how well the Microhouse has been coming along, I am sad that I cannot stay until the last screw has been driven. The house has taken its shape, but it is the detailing of home that really brings it to life, and I really wish that I could be here to make it sing. I have no doubt that I am leaving it in good hands, though, and that one of OSE's very talented DPVs will step up and carry this through.

==Walls Fully Stacked, Top Plate On==

Yesterday, the crew succeeded in stacking the full height of the wall and attaching the top plate. The final form of the house is becoming apparent.

<html><iframe width="420" height="315" src="//www.youtube.com/embed/41UfQQNG4Fk" frameborder="0" allowfullscreen></iframe></html>

Also, made a run to Menard's last night to purchase some long metal tie-down straps, some "power-lags," another drill, and some 3" screws.

=Tues Noon, Oct 1, 2013=

Work on stacking up the walls is really coming along. 11 courses completed at lunch time. Just 5 to go!

[[File:11 courses.jpg|400px]][[File:11 courses w press.jpg|400px]]

Carpentry has been moving forward today, as well. First roof panel box is built up, and members are cut for the next 6. This evening, we will insulate them and put on the ceiling side.

[[File:roof panel box.jpg|400px]]

=Tues Morn, Oct 1, 2013=

I got the first peek at the CEB floor this morning. The guys laid the last bricks in the dark last night, by the light of the film-maker's camera. I was anxious to see how it looked, so as soon as I woke up I ran up to the site before the day's work started and spent a few minutes alone with the Microhouse.

[[File:CEB floor day 4.jpg|400px]][[File:Micro exterior day 4.jpg|400px]]

==Enormous Output of Work Today==

We began the day with four courses of bricks stacked...

[[File:early morn 1.jpg|400px]][[File:early morn 2.jpg|400px]]

We started the day with laying the brick floor. We changed our plan about sand to use last minute, and local hauler Larry McPhee was a hero for bringing us a load of sand first thing. I woke the guy up this morning with my phone call, and at first he said he didn't think he could get us fit in. But when I told him where the delivery was going, he said, "The guys that build the tractors?" He showed up 90 minutes later with our sand. Thanks, Larry, for starting this great day off right.

[[File:cebfloorbeg.jpg|500px]]

==Window and Door Modules Placed==

Before stacking the bricks, we installed the window and door frame modules, plumbed them, and braced them.

[[File:Window door frame erection.jpg|600px]]

==4 Courses of Bricks Stacked==

We started stacking blocks late afternoon, and managed to get four courses stacked before nightfall!

[[File:4 courses.jpg|600px]]

The quick speed of laying up the brick is made possible by the tractor, the pulverizer/bucket, and the brick press.

[[File:loading brick press.jpg|600px]]

==Utility Module Complete==

Today we finished the Microhouse Utility Module - the heart of the Microhouse and the most complex component to assemble.

[[File:utility module complete.jpg|600px]]

==Door Loft Module Built==

The final interior module was completed this morning.

[[File:door loft module.jpg|300px]]

The next carpentry steps will be to create the exterior walls for the upstairs level.

=Sun Mid-Day, Sep 29, 2013=
==CEBs Made==

Hot off the press!! Bricks getting made and stacked. The Microhouse is about to get vertical!

[[File:Bricks coming off press.jpg|300px]]

==Rough Frames to be Erected on Foundation==

Today we will place the rough window and door frames on the foundation.

[[File:Install_frames.jpg|300px]][[File:Dims_for_frames_SE.jpg|300px]][[File:Dims_for_frames_SW.jpg|300px]]

Once the frames are in place, we will begin stacking the compressed earth bricks (CEBs)!!!

=Sat Eve, Sep 28, 2013=
==Utility Module 92% Complete==

Work began today on the utility module - the heart of the Microhouse and the module with the greatest complexity. It contains all the plumbing and the majority of the electrical systems, and is design to "plug in" to the stubs roughed in on the building site.

The process was quite smooth, with a few hitches: not being able to find a small length of 1 1/2" pipe (it was plastic-wrapped to the underside of a long 2" pipe and three of us overlooked it at first), dead batteries on cameras and photo data-dumping necessitating some stoppages (what we're doing is only valuable if others can access the information). These were minor, though, and the end of the day found the utility module nearly complete!

[[File:utility module w DWV.jpg|350px]][[File:utility module 92 percent.jpg|350px]]

==Window Frames Constructed==

The window frame is more elegant than it actually appears. It is both a direct gain passive solar heater on the top, which quickly heats a space, and an indirect gain solar heater on the bottom, which heats a trombe wall which will store heat and release it into the space later.

[[File:window module diagram.jpg|300px]]

The crew today finished three of these modules.

[[File:window frame cody seth.jpg|300px]][[File:checking to make sure window fits.jpg|300px]][[File:window module cody.jpg|300px]]

==Loft Modules Constructed==

The Microhouse loft is composed of two modules. One is sized for a king-size bed, the other is intended as a small hang-out space or for storage. Both have minor electrical components of lights for the spaces below them, the kitchen light for the large module and bathroom light for the small. The small module also contains two outlets to bring power into the loft.

[[File:small loft frame.jpg|300px]][[File:loft module electric.jpg|300px]][[File:loft module light.jpg|300px]]

==Door Frame Re-Work Done==

On my first visit to Factor e Farm a month ago, I built a door frame with their intern Lucas. I called out the wrong dimensions for the opening, though. A couple weeks later, I had a moment where the first thing I thought of when I woke up in the morning was, "OMG, I think I messed up those dimensions!!" Sure enough, upon returning, I measured the frame and found the rough opening 2" too short in each direction. Today, the door module re-work was done. Thanks for redoing my work, Seth, so I could focus on the utility module!

[[File:Door frame seth thomas.jpg|300px]][[File:door frame module.jpg|300px]]

==Many Volunteers On-Hand==

We were blessed with many hands today...
Seth Jenkins helped run crews. John Motloch helped build and document the processes. Catherine Austin Fitts helped organize time tracking of the utility module. James Wise helped Lucas Warner, one of OSE's Dedicated Project Visitors (DPVs), and Marcin modify the tractor. Emmett McGregor, a DPV focusing on documentation, shot video, stills, and time-lapses of the day's work. Cody Harrison and Rob Beddingfield did a little of everything. Thomas and Noah Devick came mid-day and jumped right in. Rob Kirk, OSEs documenter, arrived mid-afternoon and started shooting along with Emmett. Many hands make for lighter work, and this group is a joy to work with!!

=Sat Morn, Sep 28, 2013=
==Parts laid out for utility module==
Getting materials laid out to be easily accessible when building is key to a successful workflow. Having a large table really helps! Materials are laid out in sections: DWV and supply plumbing, LP gas plumbing, and electrical.

<html><iframe width="420" height="315" src="//www.youtube.com/embed/vPrlzxFaZq4" frameborder="0" allowfullscreen></iframe></html>

=Fri Eve, Sep 27, 2013=
==Drain Pipe and Chase Installed==
Installed the drain pipes, the water inlet and the chase to enable thermal hydronics to connect to a future module.

In order to facilitate measuring the fall on drain pipes at 1/4" per 1', a small 1" jig is taped to the end of a 4' level.

[[File:jig on level.jpg|350px]]

Strings were attached to the foundation form boards; intersections show where pipes come through floor. Final dimensions shown on marked up sheet to make any adjustments needed to utility module.

[[File:strings on foundation.jpg|250px]][[File:Pipe_layout_dimensions.jpg|250px]][[File:marked up pipe layout sheet.jpg|250px]]

3" blackwater pipe was installed first. Gravel was dug out, pipe was put in place and checked for proper fall. "Shit runs downhill," the old plumber's golden rule says, but it runs downhill best if it sloped at 1/4" per 1'. Too much fall, and liquids can outrun solids.

[[File:Blackwater w level.jpg|350px]]

Always prime pipe before gluing to ensure a good bond. The vent pipe for the blackwater outlet (not shown in original drawing) penetrates the floor to come into the utility module. String intersections were used as guides and pieces were held in place to determine pipe lengths for cutting.

[[File:priming pipe.jpg|350px]][[File:checking pipe location.jpg|350px]]

Once the 3" pipe was in place, a similar trench was dug out for the 2" line using the string as a guide. Here, the 2" and 3" lines are shown exiting the building. Both were kept low enough that the 6" line can go above them.

[[File:2 inch line excavation.jpg|350px]][[File:2 and 3 inch pipe exit.jpg|350px]]

The last pipe to go in was the 6" chase that will eventually contain insulated PEX pipes to carry thermal energy to a future module. The 90 was too tall, so one of the bell-ends was cut off of it. Once the pipes were installed, the ends were capped with plastic bags and duct tape to avoid debris getting inside them before use.

[[File:6 inch pipe.jpg|250px]][[File:6 inch 90 cut.jpg|350px]][[File:capping pipes.jpg|350px]]

<html><iframe width="420" height="315" src="//www.youtube.com/embed/v8qdbueT-Jg" frameborder="0" allowfullscreen></iframe></html>

The end result... pipe stubs right where we want them to be!

==Meeting with Walter Grondzik, PE==

Walter Grondzik is the author of Mechanical and Electrical Equipment for Buildings, the "bible" on building MEP systems and passive design, as well as The Green Studio Handbook, a reference for incorporating sustainability into schematic design. This afternoon, he graciously donated an hour and half of his time to the project. We talked about small design details regarding thermal performance, as well as ways of gathering some solid data on building performance.

[[File:MEEB11-Cover.jpeg|150px]][[File:GSHcoverfinal.jpeg|150px]]

Here's a video of Walter discussing the uses and rationale for adding sensors to a building - then we'll look at some details that were discussed.

<html><iframe width="420" height="315" src="//www.youtube.com/embed/4hWGPiU3zA0" frameborder="0" allowfullscreen></iframe></html>

Walter gets excited about building science. I wish I had captured on video our conversation about the different types of data collection he recommends. Here is the list:
1. Sensors, like the ones recommended in the video for ambient temperature, relative humidity, and illuminance.
Plug-ins to the sensors that are thermal probes.
2. Infrared (IR) Camera study
3. Blower door test.
Ball State has this equipment, but it needs to be looked into if it could be brought to the site at a later date during building operation.

One item we discussed was getting the best performance from the direct solar gain heating system (heating of the CEB floor by sun shining through windows). Walter highly recommended putting in a thermal break between the floor and the foundation. Without this break, there heat will travel easily from the floor to the foundation. He suggested a 1" thick piece of foam, but he agreed that a 1/2" piece would be acceptable. Even at 1", the plaster and a trim board would cover it.

[[File:Foundation section w thermal break.jpg|750px]]

Walter reviewed the window design including the indirect gain solar heating system, and thought it was an idea that would work well. He also felt that the amount of glazing to floor area seemed appropriate.

[[File:Window_frame_labeled.jpg|750px]]

This modular system - combining both direct and indirect gain systems - balances the quick warming felt with a direct gain system and the time-lag heat release experienced with an indirect gain system.

We spoke quite a bit about air sealing the building - a critical component when maximizes passive gains. He liked the idea of using a foam gasket (referred to often as "sill seal," in the field) between the window and door frames and the blocks stacking up next to them. Also, between the block wall and the top plate.

(More to come soon...)

==Utility Module Design==

[[File:Microhouse_utility_module_full.jpg|750px]]

The utility module contains all the connections for the electrical and plumbing, and doubles as a partition wall separating the kitchen from the bathroom. This particular location allow all the plumbing connections to be inside a single wall.

[[File:Microhouse_utility_module_no_framing.jpg|750px]]

==Interior Partitions and Loft==

==Precise dimensions for pipe layouts==

[[File:Pipe_layout_dimensions.jpg|750px]]

Notes:
1. Measure and mark opposing interior form boards with dimensions listed.
1a. Measure from outside of inner form board (in other words, from what will be inside of concrete).
2. Put small nail into form top at location of mark - string between similar mark on opposing form board.
3. Run designated pipes under foundation formwork and make sure vertical pipe is directly under
proper intersecting strings.
4. 6" chase for future hydronics does not need to be at any slope.
5. 2" graywater and 3" blackwater lines MUST BE AT 1/4" slope per 1' of length.
This is required for proper drainage, otherwise liquids will outrun solids.
6. Pipe layout shows 6" chase running over 2" and 3" lines, however, it is typical to conserve as much
elevation as possible when exiting graywater pipes... best practice will be to run 2" and 3" pipe
out just below bottom of foundation formwork. 6" pipe will most likely run beneath level of 2" and 3" pipes.
7. Run pipes past foundation forms by roughly 5' and cap with cardboard/duct tape or old rag, etc.
Leave vertical pipes at a length of 1' taller than foundation forms. Cap this end, as well.
Staking the vertical pipe in place with rebar will prevent it from getting disturbed.

Pipe Elevations:

Updated bracing for concrete forms. Almost all bracing will occur with threaded rod, placed through holes drilled in the forms, and secured with a washer and a nut. Pattern for installation is shown in below photo. Staking can be kept to a minimum... 2 stakes per corner... just to keep forms square and in place.

==Flyer Created and Distributed in BSU CAP==
[[File:Microhouse2013_build_flyer.jpg|750px]]

This flyer is being placed in the hands of key professors and students in order to recruit talent for our first Microhouse build. I have no doubt that we will be able to fill a van with bright young designers to help us execute this project.

==Speaking Engagement Booked==
I have been given a time slot during Ball State College of Architecture and Planning's Alumni Symposium to present the Microhouse project. During my last presentation at the CAP student symposium, I spoke to a standing-room-only crowd of over 200 students and faculty. I expect this time will be no different. The timing is perfect, too, as it comes just a month after we will finish the build of Microhouse 1.

==Profile in Book on Post-Petroleum Design==
I have arranged a profile to be included in Dr. George Elvin's upcoming book on post-petroleum design that will feature the Microhouse. George and I became friends during my time as a student at Ball State, and he had been planning to include a profile of my other natural building work in his book. When we crossed paths this morning at a Muncie coffee shop, he was working on the book and reminded me that we need to schedule an interview. I suggested we focus the profile on the Microhouse and do the interview after I return from the build week. I'm very excited about the exposure this can bring to the project!

==Current Microhouse Design and Overview of Build Week==

[[File:exterior.jpg|400px]][[File:overhead.jpg|400px]][[File:Interior_shot_of_kitchen_and_loft.jpg|400px]]

During the last few days of September and the first week of October we will be constructing a prototype house, using prototype machines, and using a prototype process: swarming construction. Numerous volunteers, with various skill levels, will be refining a method of parallel processing to construct modular components of a house that can be quickly assembled to create a beautiful, durable, and sustainable dwelling for a couple: the Microhouse.

The build processes will proceed from an instruction manual, currently being designed, that will open the doors of creating one’s own shelter to almost anyone.

Every step of the process will be rigorously documented. As components are built, the instruction manual will be marked up with times for each step and notes for how both the process and the manual can be improved. At the end of each work day, debriefing sessions will capture lessons learned to refine the process. As the next day’s work proceeds, while some volunteers are building in the field, others will be revising the manual to reflect the lessons learned the day before. In this way, the learning will be captured as it happens. At the end of the build week, the product we will deliver is far more than a house, it is a process that makes building more accessible to everyone.

=Sunday, September 1, 2013=
==Update on Prep Weekend for Microhouse Build==

Over the past two days, Marcin and myself have refined numerous details of the Microhouse design. We have settled in on a roof panel module that we believe will be quick to assemble in the field by removing the tight tolerances necessary if panels mate tightly with one another. In this system, panels will be spaced apart roughly 14" or 15", eliminating the need for precision. 2' wide sheets of plywood will be screwed into place from the bottom to contain insulation, and once insulated, 2' wide sheets of OSB will be screwed onto the top.

[[File:roof_panel_sketch.JPG|300px]][[File:roof_panel_sketchup.JPG|300px]]

The idea of the modular components for the mechanical and electrical system has evolved into the module being one of the partition walls in the building itself. This wall will contain the electrical and plumbing connections of the sink, shower, toilet, stove, and electrical receptacles. The partition wall will also support the loft panels. Loft panels will be pre-wired for electrical connections, and will plug in to receptacles on the electrical module-wall.

Layout for the interior of the Microhouse was determined.

[[File:layout_microhouse.JPG|300px]]

An intern at OSE, Lucas, and I built the rough door frame from the instructions I had created. We timed each step of the process, and also marked up the instruction sheet for the second iteration. All pictures can be found on trovebox under the tag "microhouse."

Spoke with both Walter Grondzik ($50/hr for up to 10 hours) and Ryan Zaricki ($40/hr - 4-5 hours for hydronics) ... both are interested in contributing to the design of the project from an engineering perspective. Ryan had several ideas for moving heat with hydronics from one module to another. He has worked on several such projects. Walter is willing to consult on any MEP issues and to review the passive heating/cooling strategies used in the design.

[[File:perspective.jpg|800px]]

Perspective shows earthen walls, door and window frames, bond beam, and roof panels.
My feeling is that with the loft, there is too much wood framing... the design no longer celebrates the earth blocks like it should... too much carpentry involved.

[[File:Direct Solar Gain.pdf]]

[[Image:MHsolar.jpg|900px]]

Passive Solar - Direct Gain

Chosen as the best passive heating strategy because of the building size. Future designs should explore indirect gain systems, as well. The page of calculations is a starting point for determining apertures.

Notes, in addition to what is on drawings pages (should be added to drawing pages)
-Aperatures must be within 15 degrees of true south (north, in southern hemisphere) for the building to receive 90% of optimal winter heat gains (Green Studio Handbook 107)

also note that the Green Studio Handbook states…
“The first, and most important step in the design of a passive solar heating system is to minimize the rate of heat loss through non-south-facing envelope components (including infiltration losses).” (109)

The single-wythe version of the CEB building will have the potential for large heat losses. Although thermal mass can help, uninsulated earth walls, when they get cold, they take some time to warm up. My experience in the earthen section of my home is that if I am at home throughout the day or at least in the mornings and the evenings, the home will stay cosy. If gone for a couple days in the winter, it takes a half a day or better to make the home feel good again.

The double-whythe section offers greater potential to use the solar gain by being better insulated.

==Roof Panels==

[[File:Roof Module.pdf]]

[[Image:mhroofmodule.jpg|900px]]

[[Image:mhroofmodule2.jpg|900px]]

Despite an enormous amount of information on prefabrication on the internet and at the library, it is clear that we are not working in the mainstream here. Every prefabbed roof panel I could find was a single, lifted-into-place-with-a-crane-type. We want something that four people can comfortably lift to a height of 8+ ft. Ideally, we want this technology replicable on two-story and greater buildings.

My explorations were based on the idea that four people could move a panel with a weight of about 200 pounds. The weight for the first iteration of the roof module is about 180 pounds without straw infill. (add weight calculations to drawings – also, final documents should include both English and metric units).

I think that the roof panel design can be improved as the details are explored. I think encasing the open side of the panel so that the straw cannot impede the panels coupling together would be slick. Something like luan plywood or masonite. Ideally, this thin piece is caulked into place, and the panels are caulked together when assembled.

The roof will have more linear feet of potential crack than any other component (assuming that the stucco is impermeable to moving air).

I would like to add to the schedule of events for the Labor Day visit that we build a full-scale test of a roof panel and track the process closely. It also makes sense to prebuild a jig for assembling the roof panels.

==Construction Process==

Numbers listed in contract add up to 28.

I think the mechanical unit might be best conceived as two units – one for plumbing, one for electrical – the idea of having critical connections of water and electricity and gas all next to each other is uncomfortable, indeed. This would break the team for the mechanical unit into two teams of 2.

What type of stucco is being used? Depending on the answer to that question, I think the stucco team of 4 could be smaller earlier in the day. We could go with 10 for bricks – 3 sliding and 5 laying. This could be one way of re-arranging if we are trying or needing to stay at exactly two dozen volunteers. If not, I think your numbers for adding up to 28 are comfortable.

==House Layout==

The two modules, separated by a courtyard, will create a wonderful outdoor space to be used for eating (cooking even, if desired), for relaxing, and for entertaining. However, two buildings separated require two separate MEP systems. Is it possible to arrange the building program so that functions are separated that have similar MEP needs? Could one space function without plumbing and gas?

One module with electricity, data, plumbing and gas:
*Kitchen
*Shower
*Toilet
*Dining

One module with electricity and data only:
*Bedroom (sleeping loft?)
*Living space
*Work Space

==Brick Stacking Patterns==
[[Image:brickstacking.jpg|600px]]
This makes the most sense to me as a couple trying to build a microhouse. Why plumb, and water a space that I just want to sleep in? Separate functional spaces. Esp in hot climates an outdoor kitchen is great, but that provides shade.
