Where to Place a House?

So you purchased some land and you are wondering where and in which direction to place your home?

We currently know of three considerations which pretty much answer this question:

  • We sleep with our heads in the east and our feet in the west.
  • We’d like to benefit from passive-solar heat – which means most of our windows (and thermal mass considerations) will be facing south
  • We’d like to have a great view

The order they are in is not random – it reflects our priorities. It’s hard to enjoy a nice view from a cold house. It’s also hard to enjoy a nice view in a warm house unless we sleep well. So sleep, warmth and view is how it goes.

Once that is set it can be useful to get more specific about the actual position of the sun over the months and seasons of a year. You can then place the sun relative to other natural elements in the landscape (hills, trees,etc.) and then decide where is best to place windows to make the best of what sunlight is available.

One way to do this is to actually be on-site for a year and make measurements. When this is not possible there are solar calculators to do the trick for you.

To do this you will need a solar map calculator – a few of which are available online:

  • I think the easiest and friendliest calculator is at PVEducation – where you can easily shift the time of year to see the solar path change.
  • A simple and useful charting tool I found (so far) is SunPosition Calculator which has basic free functionality and extended paid options.
  • A more complex and elaborate tools can be found at SunEarthTools.

To use these tools you will need to find the latitude and longitude of your site location. You can do that here or just search the Internet as there are many freely available online options.

Heating Resources

We want to have a really pleasantly warm house when it gets cold outside. Building with hemp insures that we enjoy a wonderfully insulated home. Now we need to deal with heat – which includes both environmental heating and water heating.

In typically built houses which tend to be cold when it gets cold outside it’s more a brute force challenge. With an ecological house it is actually more complicated because it’s easy to design a system that overheats the house. We still don’t have a clear picture or understanding of our heating needs – though we are working at it.

In the meantime I wanted to share with you some great resources that we are using to educate ourselves:

  1. Stoves Online (UK) – it s great resource for learning about the different elements that make up a heating system with a very rich offering of solutions if you happen to live in the UK.
  2. Boiler Stoves (UK) – seems like a sister website which specifically explains how boiler stoves work and can be incorporated into a smart and efficient heating system.
  3. Radiant Design Institute – though not an appealing website has a lot of really well-grounded and useful information I believe can be very useful especially to do-it-yourselfers.

You may also want to visit these two pages:

  1. An animated demonstration of a boiler-stove at work
  2. An article that debates whether radiant-floor-heating is at all appropriate in well insulated eco-buildings

Concrete Basics: A Guide to Concrete Practice

I’ve been struggling to understand on if/why a concrete slab is necessary. I completely understand the need for footings and foundations – but slabs are not that clear. It’s somethinge eveyone seems to take for granted … but I am undecided on it.

Anyways …  I did come across this excellent free eBook generously published by Cement Concrete & Aggregates Australia – which seem to have many more freely available resources on their website. IF we do end up building with concrete foundations (yep – that’s an if!) we will probably hire a contractor for it – it’s one of those jobs where DIY doesn’t seem to have much point/value. Even so – this eBook is a must read because at least I know what to expect, to relate to engineering/design choices and to make sure things are getting done right on site.

I will probably be spending some time with their resources – I’ll let you know if I find anything interesting 🙂

Evolution of Hemp Processing – A Story in Images

I came across this PDF presentation on the European Indutrial Hemp Association website – it has some great and educational images in it on the evolution of hemp processing.
