Eco in Denmark: Straw bale houses earth quake resistant

My host in ecovillage "Friland", Caroline Meyer White at Engineers Without Borders in Denmark, is currently working on a specific building project in Pakistan after the flood. She and the engineers are building earth quake friendly straw bale houses with the right technique, to shelter the homeless during the cold winter to arrive! This is for the northern parts of Pakistan, where simple tents won't be enough. And here we also learned something new about straw bale houses: When constructed as explained in the link below, they are tested as earth quake resistant! This way, their new houses will not only shelter them, but also keep them more safe in the years to come, and.. it will be much cheaper to build and easier and faster to build as the locals are brought in who already know much of such building and local material is being used.

NEW INPUT: Straw and compressed straw as one of many natural materials, is different to metal/ bricks and compact material, as straw "breathes" and makes holes and space for the air to flow within its structure, so when the ground shakes the material itself "shakes" in circles with airflow and is more unlikely to collapse than a four-edge, thick wall-structure with no natural "airflow".

From abstract: "The objective of the shake table tests was to assess the seismic response of a 14’ x 14’ x 10’ full-scale house constructed with heavy detailing. The input motion was the Canoga Park Topanga Canyon record of the 1994 Northridge, California earthquake, Mw 6.7. The house was subjected to eight levels of seismic shaking, beginning at 25% of the recorded ground acceleration and increasing at 25% increments. The house survived 0.82g, twice the acceleration of the Canoga Park record. Although severely damaged, the building did not appear in danger of collapse, even at the end of the test sequence."

Eco in Denmark: Leaving farm in Kyse

Good memories from the apple ecofarm, here are some goodies:

I love the ocean.

More on the "Beatle" in the background further in this post

THE WOOD PELLET STOVE: The heating came from this modern wood pellet stove, a common ecological use in Denmark for saving money and energy. Combined with solar energy for electricity, the stove has some magnificent effects on amounts of hot water. Wood pellets, bought from left-overs at wood firms etc., are heated up to the hot water storage, which delivers domestic hot water and can supply the central heating system at the lowest possible costs.

Me on the tractor for the first time, it was fun

On a bike ride to the beach at Karrebæksminde (a very popular tourist resort), here is a funny "beatle-bridge" for ship traffic and the sign in front of the bridge says: "Save the environment, turn off your engine!" to the cars arriving to cross the bridge. Again: Motivation campaign in the danish spirit!

Eco in Denmark: WATER. The household wastewater, acid precipitation and groundwater

Fresh drinking water, acid precipitation, soil water storage, as well as wastewater and groundwater, is a big problem or challenge in today's fresh water loss and biomass growth. Not only is it unhealthy for us, but also with our spill of chemicals, important vegetation is losing minerals to grow and the groundwater itself that is moving outside of the community sewer transportation would end up disturbing already fresh lakes,coastline and rivers that we are also using and animals are in. Big, growing problem... and the EU has decided that all the member countries within year 2015 will have to make sure the water condition is good.

Where to find one solution? On my very first stop on this trip, I cannot avoid telling about their very own constructed waterland system (økologisk pileanlegg)! With inspiration from Odsherred, "Fri og Fro"-ecovillage August 9 - 16:
 

 " We're refreshing our own grey wastewater in a special-designed evaportranspiration construction!" - The folder explains, which I got hold of at the ecovillage in Odsherred, Denmark. As well as our own wastewater, it also takes acid precipitation (sur nedbør) and precipitation as it evaporates (fordamper)!

HERE'S HOW:

A polyethylene-lined basin (the ecovillage in Odsherred has installed 6 basins) filled with soil is planted with clones of willow (Salix viminalis) (piler) grown as a short rotation coppice. The basin receives input from wastewater and precipitation and has no discharge, but the water is evapotranspired by the willow and nutrients are consumed by the willow biomass, which is cut down regularly. 

The species Salix viminalis was effective in evapotranspiring (fordampning). It was concluded that the yearly ETA (måling av fordampning) of the constructed wetlands is more than twice as high as potential evaporation calculated from Makkink. The average potential evaporation (Makkink) in Denmark is 582mmyear-1. The measured ETA from a constructed wetland (økologisk pileanlegg) in Jutland (Jylland) was 1332mmyear -1. (Source:Susanne Rosenild,2005).

The willows, which are fast to grow, are using the minerals in the water to grow and evaporate the water through its leaves. The evaporated water is completely clean,and the report also says the system is called "oasis effect", as it basically is a constructed oasis! Some waterland constructions also plant more vegetation and long rows of willows especially around such a site, to create yet more feedback to the ecosystem. The wastewater is conducted from the single grounds til four bottom tanks, where it gets pushed through some cords up to the waterland construction. Here there are some instruments to analyze the incoming water and water level. 

If there is something wrong in the system, the whole construction actually sends an sms and alarms one of the members of the ecovillage community! Also when there is too much wastewater. What an invention!

Eco in Denmark: The 100% Renewable Energy Island

BEST OF BOTH WORLDS: 

Samsoe (Samsø / Samso) is an island between island Sjaelland and the Jylland in Denmark, 114 square kilometres and 4000 inhabitants. We took a local ferry to find an island with top technology from both worlds! The farmers, the scientists, the locals and the top technical equipment for becoming a leading flagship of energy. Today, after 10 years of developement, Samsoe is hosting lots of "energy tourists" and curious energy enthusiasts from all over the world. How they made it happen, is a nice story itself. The key is participation. This trip was done August 9th to discover how this island is 100% self-sustained from renewable energy, and managed to get a guided tour around the wonderful island:

Eco in Denmark: Copenhagen eco city

I'm in Copenhagen. Because of the ecovillage development, unfortunately city developers think that the bunch of conscious consumers are moving out of the city and that there is no need for green market in the biggest cities. That is wrong. Green implementation can be done anywhere, and eco cities are starting to see the light - with China as a frontier so far (ShannonMay's projects etc). In Scandinavia, the leading eco city is by far Copenhagen. These few days of mine here, just confirms this by walking the streets. Above is an english presentation video and here are some great articles in norwegian language from norwegian tourist information centres about Copenhagen eco city:

Eco in Denmark: Motivation campaigns everywhere

The danish people, from private institutes and businesses -to governmental plans, are very good at public attitude campaigns through posters,products labels and commercials about global changes and personal growth, which we do not have this much in Norway.

It came as a shock to me to discover how well organized this informal arts-campaign works all over the region! In norwegian stores, the most common bag is a plastic bag when you buy something.

In a danish store, the most common bag is a recycled bag, and it is for the same amount of cost as a backwards-plastic bag in Norway, just alittle less than 1 DKK/1 NOK almost. Whereas recycled bags in Norways would cost 1,70 DKK/NOK almost and bags of other material than plastic - about 17 DKK/NOK.
I will post some examples of the messages printed. Even on the Coke bottle, which is made of recycled plant material by the way, one has a message. 

 And every train has a garbage bag with message, as well as every station has a poster with one. Shops and retails have recommended products with HUGE signs "Ecological" on the front row in the stores, and not hidden in the back of the store. I can name examples: Superbest, Super Brugsen, Lidl, and also the smaller ones.

CORE VALUES IN CULTURE: Without glorifying the danish people as one, it is something special of danish cultural spirit to do information like this, and few people complain about the informal arts because the individuals of danes have something rare in common; to develope common ground at the bottom-up philosophy. As it is not only governmental information, it shows that private businesses care just as much about core values of the people as any rural person does.

The danish people are very proud people of their core and stable social culture, so they keep feeding it to their citizens. If things like this happened in Norway, I think people would immediately start saying there are some few leaders trying to put an idealistic view into some peoples' minds. Instead in Denmark, it is a part of their culture to motivate and engage people in social core values.

Eco in Denmark: Odsherred.

Arriving in Odsherred on August 1-9, there was a little village in the middle of the yellow fields. 16 families with children live here, the ecovillage established at a parking lot where the public road ends. In Denmark it is not called "ecovillages", though rather eco society. This is because ecovillages do not only appear in the middle of yellow fields, but also nearby the towns. Because they are so integrated as local contributors, that they are not separated from the average citizen and not seen as anything "exotic". 


Welcoming me at the community, were two parents who were architects from Copenhagen and little girl. Sun was shining, and the garden smiling at my willing hands to take a big deep dig into its soil. Like a village, these houses do have quite big gardens. The biggest investment they probably had to make, was acres of space and field to build their sustainable home. The rest of the upwards - and widely constructed area, costed them the minimum of money.

To understand how cheap it is to build this home and how much they gain from its sustainability, to create yet more freedom and yet more flexible activities in everyday life, one has to know its ground philosophy and ground fundament which I'll try to explain through some of these blog posts. This is not something new in Denmark. In fact, Norway where I come from, is estimated 15 years behind - both in the infrastructure and development of societies like this. 

But the interesing part, is that all industrial countries seem to move towards ecological balance as a result of consumer needs and consumer's deadly health from functional lifestyle, so therefor Denmark and Germany are frontiers of life style whereas countries like Norway do have a lot of peace development across borders and energy research. The sad thing, is that we seem to group ourselves as "they do this" and "we do that" , instead of looking at the society as one building and developing board where we need the eco balance as the pre-fabricated lifestyle seem not so much in balance at all. I'd avoid saying commercial lifestyle, as ecological lifestyle can be super commercial when given a chance, like we have proves in Denmark. So there is no separation between earning and slow consumption here.  

In fact, slow consumption and models given thoughts to profit the society and planet just as much as yourself, seem to be the winning gain in the end. And this we must not forget; our future and now is dependant on each other both ways. So if you want a good now, look at coming aspects so that you can relax. Knowing that your future will be a good one is surprisingly healthy for stress and concentration it seems here at the ecovillage. And the only "stressful" thing you really need to worry about, is to dedicate time for creativity and social meetings to develope the common ground where your house lives. 

Yes, lives. The house lives. And by building breathing straw bale houses, external air conditioning is a no buy and no use. The more natural material, the more they figure out how the elements work with each other to get all the resources we normally just copy from nature in the other synthetic way anyway.
