Reine Energie Reinertrag

Raiffeisen Bank, 818 kW

Budapest XV., Kesmark Street 14-13 - a corner plot on triangle-shaped area: the investment has been made neighbouring to the centre of the bank that was built earlier; in addition to the floor area of the building there was only a limited free area available.

 

When making boreholes, geophysical logging has also been carried out to clarify the geological structure of the area. The area consists of Neogene formations. On the investigated area the 8.0 m thick Holocene and Pleistocene formations are followed downward by Upper-Pannon layers. Holocene consists of thin topsoil. Holocene is followed by clayey, sandy, sabulous formations from Pleistocene period in the successive layers. Pleistocene is followed by rhyolitic tuff, clay, sand and aleurite formations from Upper-Pannon period.
We investigated reconstruction of so-called in situ state after boring on April 18, 2006 (figure 8) with temperature registration that amounted to 10.7-14.3°C depending on depth, and then we performed TRT measuring for both double and simple loop.
