If you are concerned about the environmental safety and ecological balance in the building constructed by you or for you, there are certain base factors that are to be taken care of. It is a known fact now that inefficient energy consumption and green house gas emissions are the vital causes of ecological imbalance. The first and foremost step in setting up and echo friendly Fertighaus is use of solar power in place of the traditional energy sources. The next important feature would be proper ventilation and setting up of a window frame system to support it.
Even for room and water heating, it would be better to use solar power instead of the electricity from other traditional sources. A heating system that would condense the gas used in boiler will ensure fuel efficiency of the highest order and lowest environmental pollution as a consequence. Apart from installing Garten or Naturkost so that harmful gas emission, especially that of Carbon Die Oxide is reduced to the basic minimum and whatever is emitted is taken care of the green plants around the building, you can also use efficient insulation system like 0.2 watts/m2C U-values in the walls, roofs and even floors. Using low energy light bulbs will be very helpful for the process.
