In recent years, Building-Integrated Photovoltaic/Thermal Double-Skin Façade (BIPV/T-DSF) shows great potentials on improving indoor thermal comfort and energy efficiency for buildings. Previous studies assessed both of a BIPV/T-DSF building through the use photovoltaic devices ventilation types BIPV/T-DSF, however, which did not evaluate effect other dominant design parameters BIPV/T-DSF's per...
Matching street-level images to a database of airborne images is hard because of extreme viewpoint and illumination differences. Color/gradient distributions or local descriptors fail to match forcing us to rely on the structure of self-similarity of patterns on facades. We propose to capture this structure with a novel “scale-selective self-similarity” (S) descriptor which is computed at each ...
Modeling of urban facades from raw LiDAR point data remains active due to its challenging nature. In this paper, we propose an automatic yet robust 3D modeling approach for urban facades with raw LiDAR point clouds. The key observation is that building facades often exhibit repetitions and regularities. We hereby formulate repetition detection as an energy optimization problem with a global ene...
Data from the Hyperspectral Mapper (HyMap), which is acquired with a field of view (FOV) of 61.3 degrees, is disturbed by the bidirectional behavior of the covered surface and its complex geometry. The resulting phenomena, an across-track brightness gradient and spectral differences caused by shifted objects, were described and analyzed in detail. An appropriate correction method for the object...
What is believed to be the first fluorescence imaging of the facades of a historical building, which was accomplished with a scanning fluorescence lidar system, is reported. The mobile system was placed at a distance of ~60 m from the medieval Lund Cathedral (Sweden), and a 355-nm pulsed laser beam was swept over the stone facades row by row while spectrally resolved fluorescence signals of eac...
In recent years there has been an increasing demand among home owners for cost effective sustainable energy production such as solar energy to provide heating and electricity. A lot of research has focused on the assessment of the incoming solar radiation on roof planes acquired by, e.g., Airborne Laser Scanning (ALS). However, solar panels can also be mounted on building facades in order to in...
This research is part of the MetabuildingsLabs project on Open Innovation Test Beds, aimed at providing a platform for open source, access and data technology providers, with focus building facades. Within this paper, we adapt digital twin paradigm façade testing facility, using tools. We formulate conceptual system architecture based previous research, key particularities beds end-users. descr...
Influenza activity in the United States began to increase in early November 2017 and rose sharply from December through February 3, 2018; elevated influenza activity is expected to continue for several more weeks. Influenza A viruses have been most commonly identified, with influenza A(H3N2) viruses predominating, but influenza A(H1N1)pdm09 and influenza B viruses were also reported. This repor...
Sound reflections at building facades are generally calculated applying the mirror image method and therefore it is assumed generally that specular reflections occur. But in many cases of structured surfaces with balconies, jutties and other irregularities these facades are obviously not acoustically plain and therefore diffuse reflections may occur. With financial support by the German BAST (B...
