House.
Our strawbale home is moving forward! We ended up getting our mortgage approved through our broker without going through CMHC but had already started shopping elsewhere by then. We went to a bank and got a better deal and lower downpayment requirement and are going in today to sign the paperwork. We knew we were approved last week so went ahead and started the construction process rolling.
Monday the driveway and more importantly house pad were place and compacted on our lot! This seems to be a good time to go over the foundation construction to be used on our home.
We are going to install a Frost Protected Shallow Foundation (or FPSF) as both the base and finish floor of our home. The site was prepped by removing the top cover of topsoil down to the substrate level of indegenous undisturbed layer of brick clay. Then a layer of shale or crushed sandstone was installed level with the existing highpoint of the land and compacted with a vibratory roller. This is where we are at now, the next step will be to form a foundation, using the FPSF Guide developed by NAHB Research Center, Inc. and using Canadian AFI values found in US Army Corps of Engineers AFI maps.
Our foundation will also be 8″ thick at the main section for two reasons, as a thermal heat sink, and to allow us to run 5″ round duct work in the slab which will be connected to a high level return plenum at the top of the second floor for redistributing rising heat from the wood stove and passive solar radiation.
I will add some photos and detail sketches on the weekend to this post, stay tuned!
How much land do you need to be self sufficient?
Assuming everyone followed Canada’s food guide, and using chicken for meat and dairy alternatives and/or trading or somehow offsetting the cost of purchasing some of the food, this is how I see it breaking down (weights of food taken from http://www.stambaughfamily.com/equiv_1.html):
Food Guide per adult male:
10 servings (1/2cup) of vegatables and fruit. Lets say your servings are 1 cup of tomato, 1 cup of spinach, 1 cup of carrot, 1 cup of cabbage and 1 cup of potato. That corresponds 74kg of tomato, 50kg of spinach, 55kg of carrot, 110kg of cabbage, and 83kg of potato per year.
8 servings of grain products. Lets use 4 servings of oats and the equivalent in flour of four servings of bread. That corresponds to 21kg of oats and 20kg of wheat flour per year.
2 servings of dairy. Lets assume soy drink, 1 cup ea. or approx. 23kg of soya beans per year.
3 servings of meat and alternatives. Let’s use chicken for all three (75g ea.) That’s 82kg per year.
More after the fold.

I came across this discussion in the comments section of
Peak Oil Debunked’s post on the chest fridge idea from the famous
mtbest article. The gist of the argument, and I have posted the relevant parts of the argument against the chest fridge, was that the orientation of the cooling device would make no difference and that the original author was sacrificing a large amount of food storage. Seeing as the original post and discussion took place two years ago I doubt I will get a response, but have decided to post my thoughts on it here.
My take on the subject is that you can buy two 15cf deep freeze’s for the same price as one side by side refrigerator freezer unit and have one set up to be a fridge and use the other as is. In my research, the standard 25cf fridge/freezer has a 15cf fridge side and 10 cf freezer side. My research also shows that similarly sized chest freezers use less energy than upright refrigerator only models. So you can in fact have more storage and pay less in utility bills for it!
