motyvacija: Prefabricated slabs energy efficiency

The main idea of the brand of energy savings is that energy efficiency of the prefabricated slabs is very low. Year after year the prices for the energy recourses are going higher and the big players in the world market such as China, India need more and more resources for their economy. In nowadays Lithuania there is a thousand square meters of the living houses which need much energy for heating and they are still without the renovation which can reduce amount of the heating energy. For that time the renovation is made only from the outside of the building. Such method is more expensive comparison with the insulation inside the building (I still haven‘t counted yet).

Look at the figure 1. Here you can see the empty places in the connection of the two slabs (figure 1). So if we may check those places we can refill them with the insulation material (spray into the checked empty spheres). It isn‘t enough so the wall in the connection corners (the most unprotected sphere for heating losses) must be covered with the insulation material. What still I need for my researches:

I must find the equipment for the detection of the closed sphere of the slabs;

The insulation coverage construction (I still have it in my mind);

The costs of the project;

The ways present it for the market.

FIGURE 2

This figure 2 shows the the insulation process. The prices for the energy at that time were low. Nobody counted the costs of heating. The quality of work was very poor; insulation materials lifetime was 8 years and even so they were not supplied at time. The incoming heating water for the radiators was 95 Celsius. Now the coming heat is approximately 60-70C. The prices for the heating are very high and they are going to be much more.

The energy losses are very high. The connections are not of needed size, materials are not of such quality as it is needed (the sand with the cement isn‘t an efficient heating resistance). Look figure 3.
