Energy efficiency

Hello to everyone!

I would like to know if any of you guys have ever read or done some research on energy efficiency on permaculture sites (or of any element on site). I am courently writting about Planning the energy efficient house surroundings in urban areas of Slovenia. I have done all theoreticall parts. Now I have a problem that there is no data about any element or property that work on permaculture principles in Slovenia.

If any of you have any relavant data about that subject I woud be glad if you can share it with me. I will use this data to present the new model of landscape architecture for Slovenia.

Thank you in advance!

Hi Danijel, welcome to permies!  I'm trying to understand your question and I'm struggling.  Could you elaborate on what you are looking for?  Or some hypothetical examples?

No problem. Thanks for asking.

I need (for example) data that shows how much electricity does one household use trough year and how much electricity is produced from solar energy or any other sources that permacultural farm/househol uses.

I need data how much water is actually used, trapped (reservoars, ponds ...) so I can calculate the amount of water that would otherwise be taken from public water supply.

The other thing is data that shows how less electricity does permacultural household uses and with what source of energy they replaced electricity.

Basically I need any data about eficiency (energy, electricity) (not theoretical) that shows numbers (word, excel tables etc.) for actual permacultural sites, houses, any systems (solar panels, water heating systems, houses from natural material etc.) so that I can make calculation on energy input reduction one household can achieve.

Thanks for your patience!

I'll be interested to see what data is posted.  I think the answer will be tremendously variable.  100% energy production on site is possible for many scenarios, it just depends on many things (energy demand, site conditions, financial capabilities, location relative to solar/wind/hydro potential).

I know that results could be very different. I need some evidence that others already did, so I can present the facts.

Later on I will do the research on the actual sites around Slovenia, but for that I need some evidence. That is the only way that the research will be approved.

So basically I would be very happy with any iformation that I can get. Even if you don't know nothing about that and know a friend who might have known this, please share this question.

TNX a million times!

Hi Danijel,
I have no data for you, but some ideas, and you may find they have their own data after some digging.
I know that if your house is well insulated it will be cheaper to heat as you won't have huge energy losses.
Many people build their own homes from local materials and are very happy with them.
You might research Earthships and other house styles such as Yurts, steel containers, Hempcrete and Cob houses.

Cob is perhaps the oldest building material, and some early structures are still standing hundreds of years later.

Boy that is a broad one. I think until you decide what kind of structure and landscape you want to model most of the examples would be much too abstract to provide any reliable evidence. Model a home using conventional techniques and one using a more efficient build technique. Search the internet for comparisons from similar climate zones, there have been a great deal of studies in european countries around passive homes versus standard construction and their energy footprints. That is where I would start...
Cheers,  David
