Gulf Island Building.


I am curious as to how the Japanese things will look like, the only thing I can think of is dividers or privacy screens. What ever they are I know they will look great.

That is a beautiful sunset buddy, I wish we would be able to see Mars tomorrow night but we got rain here for another 4 or 5 days and turning cold. Right now we have the AC on, it was 72° here today and yesterday, crazy weather. Maybe the bad weather will move away from you soon.

Not much chance of the weather changing at this time of year Jim. I just checked and we have either cloud/flurries for the next few days, along with two days of FOG. Good thing I don't need to go to town for awhile.

So I won't be able to catch Mars either. Dropping below zero ēC every night for at least the next week, so I can expect that hard water to stick around for awhile.

I did manage to get the ceiling beams covered with cedar after all these years.

In the traditional Japanese house, they actually use paper covered screens around the outside of the house. "Washi" Is the name of the paper, and it is traditionally replaced annually just before the new year. In order to do this they use a reversible glue which they make from rice.

The paper is also used for any number of other screens throughout the house, as well as for lanterns. Originally, this paper was made 10 3/4" wide, always by hand, and that had an effect on how the various Shoji screens were made...this goes back for many centuries.

Nowadays, most of the paper is machine made in order to keep the cost within reason. Rolls are typically 36" or sometimes one meter wide and 20 to 30 feet long. Some of the modern paper has additives like rayon in the mix which is supposed to assist in preventing water damage.

I'll get some pics when mine arrives.

I bet that was interesting to see how they made it by hand, I am looking forward to seeing it Keith. Is that all they had on the outside of their house, just paper? Must not have been much crime or bad winds over there.

That is really sharp Keith, it does look good.

Gulf Island Building.


Not much in the way of activity happening here these days, so I decided I would busy myself by attempting a model of the future house.

The plan is to build a net zero energy house suitable for one or two people.

The idea is that it should produce the same amount of energy that it consumes, or more if possible. What this boils down to is that the sun in one form or another will provide the necessary energy.

The cost should be no more than a conventional house after factoring in the normal electricity bill for the standard dwelling. Hooking to the grid will not be necessary.

Since there is a fair bit of information forthcoming about the design, I will chat as we go along with the pictures.

In a nutshell, the house is of double walled construction on the north, east and west sides, single walled on the south side with a solar greenhouse attached to the south side. The roof is exceptionally thick and is packed with 3 layers of R-22 Roxul insulation along with a layer of foam board on top as a full thermal break.

OK, coming up out of the ground, construction is basically a standard reinforced concrete footing and wall, with the exception that there will be a foot of drain rock below the footing itself.

Inside the footings a 6" layer of foam board is laid on compacted (or undisturbed) flattened ground.

Next is a swimming pool liner double the size of the floor area. A foot of drain rock is placed inside the liner, and the top half of the liner is folded over and sealed making a big bag. This bag will eventually be filled with water.

On the model, you get to use your imagination here, so while we don't have any foam board, or liner, or rocks or water, we will get the basic shape of the final floor made.

I started by putting some strips of wood together to derive the shape of the house and greenhouse floor.

The house floor will be about 18" higher than the solar greenhouse floor and there are a couple of reasons for this.

One is so that there will be room for some clerestory windows at the top of the south wall of the house, and another is in the case of any liner problems in the house, water can be drained down into the greenhouse, which will also have the rock/water liner installed.

I should give credit here to a fellow named Meares for this rock/water system under the floor. He and his compadres were investigating ways to see if they could make a commercial greenhouse more efficient to operate, without unduly increasing the cost. He came up with this system and used his own house as a test bed. He put an addition on his house (quite small) and added a somewhat poorly designed greenhouse on the south side. He used only 6" of rock under his floor, which was poured concrete.

The water in the liner was either heated by solar collectors or a wood stove. It proved to be incredibly effective both as far as comfort and cost went. He kept records for many years on the performance until his house was sold.

So my thinking is that with a bigger rock bed covering the entire floor area, that the temperature swings in wintertime will be kept to an absolute minimum.

The rock bed in both the house and greenhouse will have a three inch thick poured concrete floor. That may either be used as is, or Bud will come and tile the whole shebang for me.

So here is what the floor area looks like at 1/12 scale, or one inch to the foot.

That part was pretty easy, and I can only hope that the real thing won't take too terribly long. So now we get to the actual framing of the building, which has an overall size of 28' by 28'.

I made a setup for this little saw that I have to cut scale size lumber, it actually turned out to work really well.

Here I am gluing up a cutting board in preparation for getting out the various studs etc.

The blade is just 2" on that saw with very fine teeth, so it makes dead smooth cuts.

Here is a giant hand doing the deed, gang cutting several boards at once.

And after a short while, there is a stack of lumber ready to go.

One nice thing about building a scale model, is that you can cut 28' long wall plates. Makes life easy.

Here is the first wall being framed using liquid nails. I have to tell you that it would be much faster to nail the full size wall together than building the model wall, seriously. This will be the inside back wall.

There will be some deep trusses made specially to fit, and here is the first one being assembled. Sorry about the crappy pic.

You will be able to see what they look like later when the assembly goes together.

Here I drew out the end wall layout on the floor and used that as the guide to frame the end walls.

Naturally, as soon as I had two walls made I had to do a test fit to see what they were going to look like.

This was just temporary, as the greenhouse was the first section to get built.

Here's a peek at the inside front house wall, with the greenhouse walls framed in behind. That is some veneer I had glued to the wall to keep it square.
