Creación de un estilo de vida sostenible en Patagonia パタゴニアでサステイナブルな暮らし作り
I visited the earthbag building blog of Owen Geiger today. I go there often, loads of useful information, presented in a simple manner and read of a new PAHS home being built in the USA.. Above is a photo from the blog.
“Earthen Hand Natural Building recently has created an 800 sf earthbag house on the Olympic Peninsula in Washington state. Passive Annual Heat Storage (PAHS) design features were used in this building, giving it the ability to heat and cool itself passively using the earth beneath the building and the walls themselves as a battery of heat."
Our earthbag home in Patagonia is proving that the PAHS system works and it is very simple. As we enter fall of the second year in our home, we notice that the temperature is between 8 - 10 degrees Celsius warmer than it is outside. In summer it is at least 8 - 10 degrees Celsius temperatures cooler than outside.
We live in one of the wettest places in Patagonia and the world for that matter. So removing moisture has been the biggest issue with our earthbag home. The PAHS system does just that. We put sloping plastic at least three and often to five meters around the home over a base of expanded polystyrine.
When our friends enter our home in winter the first thing they say is 'Calientito' meaning warm, even when we have no fire. And they love having warm feet. which is not what you get in regular wooden Patagonian homes, freezing feet is the norm.
We have built a sunroom at the back of the house to further heat up the home.
