At the manufacture stage both concepts worked well. Timber is a renewable raw material, demanding relatively little energy in processing. The energy employed during the manufacture and build process is only a fraction of the houses' total energy consumption during its operational lifetime. However when the house is finally constructed things begin to happen. It's now that all EKOMER's advantages begin to tell, at all levels.
The dense, very effective cellulose insulation retains the heat and therefore reduces the energy required for heating. The change over from mineral wool to cellulose means a decrease in the total energy consumption from 52,000 to 19,000MJ, ie a total of 63%. Instead of cellplast (polystyrene) under the foundation slab, the recycled glass product, Hasopor is used in EKOMER. That gives a reduction of energy requirement from ca 76,000 to 30,000MJ, ie a total of 61%.
Besides that EKOMER offers the possibility to use renewable energy sources. All houses are prepared for the connection of a water jacketed pellets stove. Pellets are a bio fuel with low emissions. The use of solar panels is positive in an EKOMER house to reduce energy requirement. Solar energy is a so called free source.
Already from year 1 the EKOMER house gives an obviously reduced environmental effect, particularly when it comes to resource consumption and CO2 exhaust emission. After 100 years the positive effect has been greatly increased, and not least the EKOMER house owner will notice economy in the wallet.
According to a newly released report from the World Wildlife Foundation, WWF, planet earth exceeds the total global consumption by 30%. If you choose EKOMER then you are siding with those who are battling to save our climate.
