This paper describes the preliminary findings of a post-occupancy evaluation campaign conducted on contemporary and energy-efficient office buildings with different façades treatments. The aim is to investigate occupants’ comfort and perceived productivity and to observe to what extent the space appearance and the façade design play a role in the ultimate user’s satisfaction and overall comfort...

This paper presents a new approach to recognize individual façade objects and to reconstruct such objects in 3D using MLS point clouds. Core of the approach is a primitive shape based algorithm, which introduces building primitives, to identify the façade objects separately from other irrelevant objects and then to model the correct topology. The primitive shape is identified against defined di...

Two groups of subjects were presented with two façade designs, one with the front façade of the existing Atlanta Public Library, an exercise in modern abstract plastic composition by the Bauhaus-trained architect Marcel Breuer, and the other with alteration that toned down its plasticity and enhanced simple relations of its parts like symmetry and repetition. The subjects were asked to recall a...

The adhesion of Klebsormidium flaccidum, Stichococcus bacillaris and Chlorella cf. mirabilis, three strains of green microalgae isolated from biofilms on façade coatings were investigated in a parallel plate flow chamber. The model surfaces tested were glass slides, and -CH(3) (mediated by octadecyltrichlorosilane [OTS] and hexamethyldisilazane [HMDZ] modification) and -NH(2) (aminopropyltrieth...

Measurements of in situ sound reduction index of a façade defines noise source’s incidence angle of 45±5 degrees (ISO 140-5). Seeing as the sound reduction index is dependent from the angle of incidence, it is of interest to examine to what extent results obtained with such incidence represent real sound insulation performances of a façade in different circumstances. The paper presents the resu...

We examine a new method of façade segmentation in a multi-view scenario. A set of overlapping, thus redundant street-side images exists and each image shows multiple buildings. A semantic segmentation identifies primary areas in the image such as sky, ground, vegetation, and façade. Subsequently, repeated patterns are detected in image segments previous labeled as “façade areas” and are applied...

We want to believe HCI has much to offer the game industry, but it goes beyond simply acknowledging differences between the HCI notion of a user and the game design notion of a player. People engage in play in very different ways––and so our evaluation methods should reflect this diversity. Game designers and researchers must be careful in establishing common frameworks for evaluation that stym...

Façade texturing is a key point for realistic rendering of virtual city models, since it suggests to the viewer a level of detail that is much higher than actually provided by the geometry. Façade textures are usually derived from terrestrial imagery acquired from a position on the ground. One problem frequently encountered is the disturbance of texture images by partial occlusion of the façade...

Urban search and rescue (USaR) teams require a fast and thorough building damage assessment, to focus their rescue efforts accordingly. Unmanned aerial vehicles (UAV) are able to capture relevant data in a short time frame and survey otherwise inaccessible areas after a disaster, and have thus been identified as useful when coupled with RGB cameras for façade damage detection. Existing literatu...

This paper describes an approach for detecting windows from multi-aspect airborne laser scanning point clouds which were recorded in a forward looking view. Since the resolution of the point cloud is much lower than from terrestrial laser scanning, new methods have to be developed to detect and, in a further step, reconstruct façade structures. The façade planes are detected using point normals...
