The rapidly increasing number of so-called media façades is one prominent example of how new digital technologies are augmenting urban environments. The majority of media façades covers most of the outer shell of a building, which gives them a 3D form factor. Due to their size and visibility, as well as the dynamic public urban environment they are usually situated in, they offer great potentia...

Media façades are a prominent example of the digital augmentation of urban spaces. They denote the concept of turning the surface of a building into a large-scale urban screen. Due to their enormous size, they require interaction at a distance and they have a high level of visibility. Additionally, they are situated in a highly dynamic urban environment with rapidly changing conditions, which r...

The rapidly increasing number of digital lighting systems embedded into architectural structures offers great possibilities for interaction. One prominent example are media façades, which are created by equipping the outer shell of a building with light emitting elements of various kinds. As a first step towards exploiting their full potential, in terms of providing interactive experiences, and...

Using media façades as a subcategory of urban computing, this paper contributes to the understanding of spatial interaction, sense-making, and social mediation as part of identifying key characteristics of interaction with media façades. Our research addresses in particular the open-ended but framed nature of interaction, which in conjunction with varying interpretations enables individual sens...

Biocide contamination of receiving waters is generally linked with agriculture. However, recent studies have shown that urban contributions should be also considered [1,2]. One of the suspected biocide sources in the urban environment is building paint. Biocides like diuron, irgarol, terbutryn, carbendazim, etc., are conventionally used in paint to control fungi, algae, bacteria and other micro...

Media façades, realized through projection systems, could be a promising technology for scalable public displays in urban spaces. With low requirements regarding the infrastructure and virtually no influence on the buildings’ fabric, projected façades offer exceptional flexibility and extensibility as well as easy maintenance. As cities are increasingly confronted with digital signage products ...

3D building segmentation is an important research issue in the remote sensing community with relevant applications to urban modeling, cloud-to-cloud and cloud-to-model registration, 3D cartography, virtual reality, cultural heritage documentation, among others. In this paper, we propose automatic, parametric and robust approaches to segment façades from 3D point clouds. Processing is carried ou...

Public spaces get increasingly equipped with displays in terms of shopping window plasma screens, electronic advertisements at the point of sale, kiosk systems at points of interest, etc. While this trend enables numerous applications in the pervasive display systems domain, it also has effects on how people perceive urban environments. In this work we describe the concept, implementation and f...

Extraction and analysis of building façades are key processes in the three-dimensional (3D) building reconstruction and realistic geometrical modeling of the urban environment, which includes many applications, such as smart city management, autonomous navigation through the urban environment, fly-through rendering, 3D street view, virtual tourism, urban mission planning, etc. This paper propos...

This work explores the double effect of urban compactness on building energy performance in a Mediterranean climate, namely the increase of urban heat island (UHI) intensity and the decrease of solar radiation availability on building façades. The energy demand of a test apartment has been calculated under varying conditions of UHI intensity and solar radiation for different urban textures. Res...
