Moisture Transfer in Ventilated Facade Structures

Analysis of coupled heat and moisture transfer in masonry structures

Evaluation of effective or macroscopic coefficients of thermal conductivity under coupled heat and moisture transfer is presented. The paper first gives a detailed summary on the solution of a simple steady state heat conduction problem with an emphasis on various types of boundary conditions applied to the representative volume element – a periodic unit cell. Since the results essentially sugg...

Stochastic Recognition of Regular Structures in Facade Images

We present a method for recognition of structured images and demonstrate it on the detection of windows in facade images. Given an ability to obtain local low-level data evidence on primitive elements of a structure (like window in a facade image), we determine their most probable number, attribute values (location, size) and neighborhood relation. The embedded structure is weakly modeled by pa...

Detection and Description of Repeated Structures in Rectified Facade Images

We present a method for detecting repeated structures, which is applied on facade images for describing the regularity of their windows. Our approach finds and explicitly represents repetitive structures and thus gives initial representation of facades. No explicit notion of a window is used, thus the method also appears to be able to identify other man made structures, e.g. paths with regular ...

Lightweight ventilated facade prototype: acoustic performance evaluation when the ventilation surface of the air chamber varies

Determination of Facade Attributes for Facade Reconstruction

In the last years more and more applications make use of 3d building models. Automatic reconstruction is essential for the acquisition and updating of the huge amount of data. For many applications it is useful to be able to transform the object representation automatically in order to generalize the geometry. For this task a structurally rich description of the object is needed. We presented a...
