In the beginning of August 2009 a long-term monitoring started in a recently built passive house near Isaszeg. The first results were presented in the last year's conference. The present paper gives an overview about a whole-year data evaluation focusing on energy consumption. During the first year of building occupancy three types of heat suppliers and two types of heat exchangers in the ventilation systems were applied and monitored, thus different heating options could be compared.

Nowadays more and more engineering structures are constructed on soft soils of low strength. High compressibility, low permeability and liability to secondary compression of these soils can result in long-term settlements and a menace with critical situations when the construction deadlines are tough. To cope with these problems several technologies have recently been developed in the embankment construction practice. Staged construction, over-filling, vertical drainage, stone columns, dynamic compaction — all of them often combined successfully with geosynthetics — are preferred to the previously predominant technology of soil replacement. Nevertheless, common design methods often do not balance properly the structural modeling, computation, economical and construction aspects. This is why a correct design may become a subject of reconsideration and modification in specific circumstances. There remains a room for innovative approaches, when conventional solutions are used. Two examples seem to prove that construction combined with monitoring may turn out to be good compromises.
The intensity of neutron beams is measured by neutron beam monitor detector at research reactors, in order to allow normalization of neutron scattering data. A two dimensional position sensitive neutron beam monitor has been developed, able to measure the distribution of beam intensity in its cross-section. The neutron adsorption efficiency of these monitor detectors are low enough to minimize the intensity loss, but high enough to provide low statistical error. Since the number of detected events is not too high, the dead time is not crucial for these detectors. A novel readout method has been developed that slightly increases the dead time but eventuates a robust, simple and flexible system. This new method relies on the serial connection of the delay-lines, minimizing the number of analogue signals. Two or three analogue signal outputs are enough to reconstruct the two-dimensional intensity matrix. Combining this new method with a comprehensive acquisition on the primary signals, the quality parameters of the detectors are also improved. Design and measurement results at the Budapest Research Reactor are presented.
